Stunning 3D Scan Reveals the Inner Workings of a Mouse Brain

A pioneering research has produced the most comprehensive map of a mammalian brain ever recorded.

The 3D diagrams showcase over two miles of neural connections, nearly 100,000 neurons, and approximately 500 million synaptic junctions—all within a fragment of mouse brain not larger than a speck of sand.

Dr. Clay Reid from the Allen Institute for Brain Science in Seattle stated, "Within this minuscule particle lies an intricate network of connections, governed by principles we are just starting to unravel."

The specimen originates from an external section of the brain called the cortex, a zone that plays a role in vision. Times reports.

Dr Forrest Collman, of the same Institute, said: 'By studying how the cortex functions in the mouse brain, we can generate better ideas and hypotheses about how our own brains work.'

His group thinks that having the ability to chart and examine the brain’s internal connections at this scale could pave new avenues for understanding and addressing neurological disorders like Alzheimer's disease, Parkinson's and autism.

He described it as the 'Google Maps for the brain', which doesn't just show major motorways but every small street, house and room inside that house.

Similar to how individuals utilize Google Maps to determine the optimal path from location A to location B, or simply to verify if such a route is possible, this comprehensive neural map enables researchers to identify whether two neurons are interconnected and precisely pinpoint where these connections take place.

What made this research particularly intriguing was that the mice needed their brain activity documented as they viewed YouTube videos. This enabled researchers to observe the interactions between various clusters of neurons.

Following this, they cut the tissue into 25,000 slices, with each slice being merely 1/400th the thickness of a human hair, before examining them through powerful electron microscopes.

The images were combined to generate a 3D model with the help of artificial intelligence. The final result not only depicts the structure but also illustrates which brain cells interact and the manner in which they do so.

Nuno Macarico da Costa from the Allen Institute remarked that one of the outcomes of their project reveals "just how extraordinarily beautiful the brain truly is."

Simply observing these neurons allows one to grasp their complexity and size, instilling an overwhelming sense of wonder towards the brain.

[PHOTOS] Giants of the Savanna: Tranquilized and Relocated from Rumuruti

A group of elephants was sedated before being moved during the relocation process in Rumuruti.

The sedated elephant had its oxygen levels and heartbeat monitored using a pulse oximeter at Naibo on April 4, 2025, in Rumuruti.

This occurred as part of the elephant relocation to Meru National Park because of a rise in human-wildlife conflicts.

The Kenya Wildlife Service stated that moving animals helps promote harmonious relationships, enabling communities to prosper while providing wildlife with ample areas for safe and unrestricted movement.

Four elephants were safely captured in the Rumuruti–Naibor area following a rise in human- wildlife conflict.

They will be translocated to the landscapes of Meru National Park.

17 Nations Set to Thrive with Sustainable Livestock and Aquatic Foods Initiative

By Sharon Atieno

Over 15 lower- and middle-income nations stand to gain from the Sustainable Animal and Aquatic Foods (SAAF) initiative launched by the CGIAR, which was previously called the Consultative Group on International Agricultural Research.

The listed nations encompass Kenya, Egypt, Ethiopia, Ghana, Nigeria, Tanzania, Uganda, Zambia, Mali, India, Malaysia, Vietnam, Bangladesh, Cambodia, Colombia, and Guatemala.

Rodrigue Yossa, the Acting Director of the CGIAR Sustainable Animal and Aquatic Foods Science Program, stated this during the CGIAR Science Week held in Nairobi, the capital city of Kenya.

Yossa states that SAAF’s objective is to enhance the quality of life for individuals in these nations through sustainable changes in animal and aquatic food systems. This transformation seeks to create inclusive, nutritious, and eco-friendly food supply chains that are both climate-resilient and environmentally conscious.

“We want to improve the livelihoods of 1.7 million people across Africa, Asia Pacific and South America, making sure that they have access to nutrient-dense quality animal and aquatic foods,” he said, adding that this will be achieved through focusing on six interlinked areas of work.

One of the areas is productivity plus, where CGIAR will support animal and aquatic food producers in a socially inclusive manner as they adopt productivity enhancing innovations which are profitable reduce emissions and increase food nutrient value.

“This is really about making sure that we close the productivity gaps through innovations around genetics, feeds and forages as well as the health bundles… The plus here means that we want these systems to be profitable, to facilitate adoption by the youth and women. We also want them to be resilient,” Yossa explained.

In the climate and environment area, the program will bolster the efforts of communities within animal and aquatic food systems to adopt innovations that will increase social, economic, and environmental resilience.

Within the One Health framework, CGIAR aims to create and promote advancements in livestock and aquaculture systems to enhance communal health and welfare. "Our objective is to guarantee the security of food production not only for the wellbeing of animals and aquatic life but also for those who consume these products, along with safeguarding overall ecological health," he stated, emphasizing that their efforts will concentrate on biosecurity measures, combating antibiotic resistance, and ensuring safer practices in both aquatic and animal food production.

The organization aims to enhance market players, particularly women, young individuals, and underrepresented communities, so they can engage more effectively in fair, low-carbon, and robust animal and fish production systems. This effort falls within an additional focal point of improving market mechanisms through strategic policies and expansion initiatives.

"We aim to create business strategies centered on livestock and aquaculture production to ease their acceptance and guarantee our connection with scalable initiatives for significant impact. This ensures widespread uptake and utilization of all the advancements generated through the SAAF program," Yossa stated.

In terms of gender, youth, and social inclusion, the initiative will back the endeavors of livestock and aquaculture producers as well as their communities to embrace fairer practices that empower both women and young people.

Finally, within the domain of data and digital solutions, the entity will aid in crafting scalable innovations at every program level to enhance overall productivity. This data will prove especially valuable for shaping policies.

The six-year initiative (2025-2030) involves a partnership between six CGIAR centers: WorldFish, the International Livestock Research Institute (ILRI), the Alliance of Bioversity and CIAT, the International Center for Agricultural Research in theDry Areas (ICARDA), the International Water Management Institute (IWMI), and the International Food Policy Research Institute (IFPRI).

5 Fakta Mengagumkan tentang Elang Alap Kelabu: Si Predators yang Memukau

Penghuni langit tidak selalu tampil dengan kesan gagah dan menyeramkan. Ada beberapa jenis burung pemangsa yang justru memiliki penampilan cukup memesona dan tak kalah indahnya dibandingkan spesies burung lain yang populer karena keindahan mereka. Salah satunya adalah elang abu-abu (elang alap kelabu). Accipiter novaehollandiae ).

Burung indah ini mempunyai kombinasi warna plumase yang amat memesona. Pada bagian punggungnya umumnya berwarna biru-keabu-abuan ketika sudah matang, sedangkan pada masa remaja berubah menjadi coklat. Di sisi lain, area perutnya senantiasa bercorak putih. Bahkan, terdapat beberapa spesimen yang sesekali tampak dengan bulu seluruh badan berwarna putih. Ini menjadikan mereka sebagai satu-satunya pemangsa udara yang memiliki penampakan seperti itu. Paruh dari elang abu-albino berwana kuning dengan ujung hitam, serta pasangan tungir berwarna kuning yang diberi lengkapan cakar se Tajam silet bisa merapatkan tubuh mangsanya secara efisien.

Dari segi dimensi, elang abu-abu memiliki ukuran yang cukup besar dibandingkan dengan spesies lain di dalam genusnya. Accipiter Panjang badan mereka berkisar antara 40-55 sentimeter, beratnya mencapai 180-990 gram, dan lebar sayapnya adalah 70-110 centimeter. Ternyata betina dari jenis ini lebih besar daripada jantan. Elang abu-abu juga mempunyai beberapa hal unik lainnya yang bakal kami bahas di sini. Sudah tak sabar ingin mengenal hewan pemangsa ini? Mari scroll ke bawah!

1. Sebaran dan lingkungan hidup spesies tersebut

Elang abu yang disebut elang alap memang berasal dari Australia dan menjadi spesies endemik di sana. Berdasarkan laporan tersebut, Birds in Backyards Burung ini cukup umum terlihat di bagian utara sampai timur dari Negeri Kanguru. Mereka juga dapat ditemui di Pulau Tasmania. Tentang pemetaan sebarannya, tampaknya dipengaruhi oleh warna bulunya. Disebutkan bahwa individu-individu yang tinggal di wilayah utara dan barat laut biasanya mempunyai warna bulu putih murni, sedangkan yang ada di timur memiliki kombinasi antara abu-abu dan putih.

Tempat hidup utama untuk elang abu-abu adalah hutan dengan pohon-pohon besar. Akan tetapi, mereka mampu bertahan dalam sejumlah ekosistem lain seperti hutan terbuka, hutan tropis, bahkan kadang-kadang area perkebunan atau pemukiman orang. Elang ini lebih memilih dataran rendah daripada gunung-gunung, biasanya ditemukan pada ketinggian kurang dari 500 meter di atas permukaan laut.

2. Masakan Favorit serta Cara Berburunya

Elang abu-abu termasuk dalam kategori pemangsanya oportunis dengan ragam pilihan mangsa yang luas. Burung tersebut mengonsumsi beraneka macam mamalia mini, kelelawar, reptil, beberapa spesies burung lainnya, dan juga serangga. Teknik berburunya bervariasi sesuai dengan sasarannya masing-masing.

Menurut laporan dari The Peregrine Fund, cara berburu utama yang digunakan adalah dengan menyamar di antara dedaunan tinggi, kemudian menunggu hingga kesempatan datang. Mereka akan melakukan serangan saat buruan tidak curiga dengan mendekati secara terbang rendah langsung menuju korban tersebut. Teknik ini cukup efisien apabila mangsanya sedang ada di permukaan tanah. Akan tetapi, ketika melawan mangsa lainnya seperti spesies yang dapat terbang, elang abu-abu harus mempercepat laju terbangannya dalam pengejaran. Kuku pada kakinya memiliki fungsi vital yaitu mencengkeram, menjepit serta membunuh siapa pun atau apa saja yang sukses menjadi tangkapan mereka.

3. Burung tersendiri yang penuh teka-teki

Di luar musim kawin, elang Kelabu cenderung memilih tinggal sendirian. Animalia Menurut sumber, burung ini tidak melakukan perpindahan musiman. Sehingga, mereka lebih condong untuk tinggal dalam area tetap dengan range spesifik. Walaupun setiap individunya memiliki range masing-masing, informasi tersebut tidak menjelaskan apakah mereka akan bertarung melawan pengganggu luar yang masuk ke daerah miliknya atau justru tidak.

Oleh karena itu, elang abu-abu ini termasuk jenis yang amat pendiam. Kehadiran mereka sungguh langka dan lebih memilih untuk menghindar apabila mendeteksi adanya ancaman. Menariknya, bila dibandingkan dengan burung lain di genus tersebut, perilaku mereka berbeda secara signifikan. Accipiter Lain, elang alap kelabu cenderung terbang lebih rendah mendekati permukaan daratan dibandingkan melayang di ruang udara atas. Memandangkan habitatnya adalah hutan tebal dengan pepohonan raksasa, kebiasaan terbang rendah tersebut malah menjadikan mereka agak susah ditemui.

4. Sistem reproduksi

Elang alap kelabu ternyata merupakan hewan yang menganut poligami tunggal. Ini menunjukkan bahwa spesies tersebut hanya akan memiliki seekor pasangan selama masa hidupnya. Masa kawin untuk elang-elang ini terjadi dari bulan Juli sampai Desember. Sebelum bertelur dan menjalani prosesi perkawinan, sepasang elang ini bekerja sama dalam membangun sarang menggunakan batang kecil kayu serta dedaunan hijau diatas dahan pohon.

Menurut The Peregrine Fund, seekor betina dari elang abu-abu biasanya bertelur antara 2 sampai 4 butir setiap tahunnya saat berkembang biak. Proses pengincubasan tersebut berlangsung kurang lebih 30 hari di mana kebanyakan ditangani oleh sang betina sedangkan jantannya pergi mencari makan. Sesudah menetas, bayi-bayinya bakal tinggal bersama orang tuanya selama 30-38 hari. Selama periode ini, ibunya yang paling sering merawat serta menyusui si anak, sementara ayah hanya fokus membekali mereka dengan makanan. Walaupun sudah mulai belajar terbang ketika genap satu bulan umurnya, masih dibutuhkan waktu tambahan yaitu enam pekan bagi anakan-elang abu-abu agar benar-benar bisa melakukan pemburuannya sendiri dan hidup tanpa bantuan kedua orangtuanya.

5. Status konservasi

Menurut daftar merah IUCN, elang abu-abu termasuk spesies dengan ancaman rendah (Least Concern). Meski demikian, jumlah populasi dari burung tersebut ternyata sedang berkurang. Diperkirakan terdapat antara 2.500 sampai 10 ribu ekor dewasa yang masih bertahan hidup dan tersebar luas sesuai wilayah distribusinya.

Walaupun termasuk dalam kategori hewan dengan risiko rendah, pemerintah Australia sesungguhnya telah memulai program proteksi untuk jenis tersebut. SWIFFT Usaha yang dilakukan pemerintah daerah meliputi pemetaan jumlah dan tempat perkawinan elang abu-abu, perlindungan habitat dengan mengendalikan dampak negatif terhadap lingkungan, serta menyampaikan pendidikan kepada publik tentang betapa pentingnya langkah-langkah pelestarian jenis burung tersebut. Penyusutan populasi elang abu-abu disebabkan oleh hilangnya habitat dan pertentangan antara manusia dan hewan.

Beragam fakta Dari elang abu-abu tadi terlihat sangat mengagumkan, bukan? ternyata, tidak selalu burung berwarna cerah mudah dilihat oleh para peneliti. Elang abu-abu telah membuktikan bahwa mereka tetap dapat menjalani kehidupan yang cukup membingungkan bahkan untuk para peneliti sekalipun.

Berapa Lama Lidah Katak Bisa Menjangkau?


categories: 

Gigi ular merupakan struktur anatomi yang istimewa dan mengundang minat. Ukuran serta jenis spesies akan mempengaruhi panjang rata-rata dari gigi tersebut. Secara umum, panjang gigi ular biasanya mendekati satu pertiga total panjang badan mereka. Maaf atas kesalahan sebelumnya dalam merespons dengan konteks yang tepat. Berikut adalah versi paragraf Anda tanpa ada perubahan konten atau makna: Lidah katak menjadi salah satu bagian anatomi yang mencolok dan menarik untuk diperhatikan. Jenis dan dimensi hewan ini sangat berperan pada lebar normal lidah mereka. Biasanya, ukuran lidah katak kira-kira setengah dari panjang seluruh tubuhnya.

Akan tetapi, sebagian katak memiliki lidah yang jauh lebih panjang atau bahkan lebih pendek dibandingkan ukuran tersebut. Penjelasan berikut akan membahas tentang struktur tubuh katak serta fungsi lidahnya dalam proses mencari makanannya.

Bagaimana cara kerjanya?

Kodok bisa mengeluarkan lidahnya yang panjang ke luar melalui mulutnya, menuju ke arah angin, untuk menangkap serangga, sebelum kemudian ditarik lagi masuk ke dalam mulut.

Agar bisa mendapatkan makanannya, mereka mengandalkan lidah yang memiliki sifat viscodelastic serta lendir dengan karakteristik non-Newtonian. Sifat di mana sesuatu itu bisa tebal (kental, lengket, hingga berbentuk cair), sekaligus juga lentur (dapat melenting dan pula merambung) dikenal sebagai viscoelasticity.

Air liur yang mengelilingi lidah katak bersifat "non-Newtonian", artinya saat ditekan, ia tak bertingkah layaknya air ataupun fluida biasa. Saat dijulurkan atau dipadatkan, lapisan tersebut justru membesar dan membuat serangga susah lepas begitu ditangkap.

Ia bisa menonjolkan lidah dengan kecepatan hanya dalam hitungan milisekon, kadang-kadang bahkan lebih cepat daripada respon serangga. Gerakan kilat tersebut diperkuat oleh otot spesifik yang berfungsi layaknya sebuah penembak sling, mengeluarkan lidah hingga melewati bibir luar mulut kodok.

Sesudah lidah menyentuh serangga, ia akan menghasilkan sebuah lendir yang bertindak layaknya lem untuk menahan korban secara aman. Lendir tersebut memiliki proporsi ideal di antara kekentalan dan fleksibilitas, membantu katak tetap menjaga genggaman yang kuat ketika menarik mangsa dari mulutnya.

Penglihatan hebat katak memiliki peranan besar dalam mekanisme tersebut. Dengan kemampuan uniknya, katak bisa menangkap dan mengawasi gerakan serangga yang gesit secara tepat, membantu mereka untuk menyempurnakan momen tepat menjulurkan lidah sebagai serangan.

Setelah serangga itu ditangkap, lidah katak akan kembali ke dalam mulutnya bersama mangsanya yang sudah terjebak dengan aman.

Penampilan lidah katak

Lidah katak merupakan struktur organ yang lunak, lentur, dan ototnya terdapat guna khusus dalam proses penangkapan makanan. Berbeda dari lidah manusia, lidah katak umumnya lebih luas dan datar dengan permukaan yang licin, membantu mereka menangkap serangga serta hewan-hewank ecil lainnya dengan cara yang efisien.

Ia terletak di bagian depan mulut katak, bukan di bagian belakang, sehingga memungkinkan ia untuk melintir keluar secara cepat dan menjangkau jarak yang cukup lebar dari bibir mulut katak.

Ibuan ini memiliki tekstur agak kasar yang ditutupi oleh lendir spesial dan sangat lengket, membuatnya mudah untuk menggenggam prey secara aman.

Bagian itu umumnya memiliki warna pink muda hingga cokelat, walaupun tingkat kecerahan dan nuansa bisa saja berbeda-beda bergantung jenisnya.

Mengapa begitu panjang?

Perubahan pada lidah katak berkorelasi dengan jenis serangga yang menjadi makanan mereka. Lidah yang panjang dimiliki oleh katak untuk mengejar prey berupa serangga penggerayangi udara tersebut.

Sebagai akibatnya, katak harus mengembangkan cara untuk menangkap serangga tanpa perlu bergerak terlalu banyak, sebab mereka hanya bisa lompatan pendek.

Sebuah hewan yang dapat terbang atau lari mungkin berhasil mengejar dan mengalahkan serangga, namun sebagian besar serangga bergerak terlalu cepat bagi katak pelompat untuk mendapatkan mereka.

Lidah yang ekstensif memungkinkan mereka mengambil serangga tanpa perlu berpindah posisi atau bersusah payah dalam pencarian makannya. Dengan pertambahan panjang lidah katak tersebut, peluangnya pun bertambah besar untuk mendapatkan mangsa.

Seberapa cepat lidah katak?

Katak merupakan predator alami bagi serangga, di mana mereka menangkap makanan dengan bantuan lidah yang bergerak sangat cepat. Proses ini memerlukan dua otot khusus yaitu retraktor dan pemanjang.

Mereka memiliki lidah yang bisa menjulur keluar dan menangkap serangga hanya dalam waktu kira-kira 0,07 detik, yaitu lebih cepat dari sekedar menyipitkan mata.

Otot penghisap lidah mereka dapat mengembalikan lidah ke dalam mulut dengan kecepatan 12 kali lipat dari percepatan gravitasi, melebihi tingkat percepatan yang dihadapi oleh astronot selama peluncuran roket.

Berikut adalah tiga katak berlidah panjang.

1. Katak banteng Afrika

Katak Banteng Afrika, dikenal sebagai Bullfrog Afrika dalam bahasa Inggris, merupakan jenis katak raksasa yang bisa berkembang hingga panjang 9 inci dan bobotnya sampai 2 kilogram. Mereka memiliki kulit berwarna hijau keabu-abuan, sementara bagian dagunya biasanya memancarkan warna kuning hingga jingga. Selain itu, laki-lakinya cenderung lebih besar dibandingkan perempuannya.

Dewasa ini, lidah mereka berukuran kira-kira 3 inci. African Bullfrog bisa bertahan sampai usia 16 tahun dan akan memakan apapun yang berhasil dimasukkan ke dalam mulutnya, bahkan mencakup burung-burung kecil. Mereka menggunakan lidah yang panjang tersebut untuk menangkap makanan seperti jangkrik, laba-laba, cacing, serta ulat.

2. Bullfrog Amerika

American Bullfrogs berasal secara alami dari sebagian besar wilayah Amerika Utara dan umumnya ditemukan di lembah-lembah, telaga, danau, serta arus sungai yang melambat.

Speesis ini bisa berkembang sampai dengan panjang 8 inci, sehingga membuatnya menjadi katak terbesar di antara spesies lain pada benua tersebut.

Kodok ini mempunyai rahang besar yang bisa dibuka cukup lebar untuk mengonsumsi makanan sampai separuh panjang badannya, serta memiliki lidah yang ekstensif dengan ukuran kira-kira dua inci.

Katak tersebut terkenal pula sebagai pemangsa ular, katak, salamander, udang-udangan, serta hewan-hewan kecil lainnya yang berada dalam jangkaunya.

3. Katak goliath

Katak Goliath, yaitu jenis katak dengan ukuran terbesar serta mempunyai salah satu lidah panjang tertinggi di antara katak lainnya, berasal dari wilayah Afrika Barat dan sering kali dimiliki sebagai binatang piaraan.

Kamu bisa menjumpainya di Kamerun, pantai-pantai, serta Guinea Equatorial. Ikan ini mampu berkembang sampai panjang 12 inci dengan lidah berukuran 3,5 inci yang dimanfaatkan untuk mengejar mangsanya.

Mereka memakan aneka jenis binatang, mulai dari serangga, laba-laba, sampai mamalia mini serta amphibian lainnya seperti salamander, kodok, dan ular. Katak Goliath bertempat tinggal di hutan lebat tropis yang terletak tidak jauh dari rawa, sungai besar, maupun aliran air perlahan.

Katak goliath meletakkan telurnya di perairan dangkal dan beroksigen tinggi, lokasi ideal untuk berudu menetas. Larva-larva tersebut kemudian mengonsumsi tumbuhan air bernama Dicraeia warmingii, yaitu jenis rumput air yang menjadi sumber makanan primer bagi kecebong hingga mencapai kedewasaan.

Ancient "Vehicles" Traced Back 20,000 Years Found in New Mexico

A recent study indicates that the first known inhabitants of North America utilized wooden contraptions for transporting goods—and potentially humans—over 20,000 years ago.

Scientists found drag marks resembling those of a sled next to ancient footprints at White Sands National Park in New Mexico, which could be oldest human footprint site in North America.

The Indigenous participants involved in the research indicated that the markings were likely created using a travois, which consists of a wooden structure formed by two poles tied together, as stated in the study released in the January issue of the journal. Quaternary Science Advances .

The Indigenous peoples of the Great Plains, which encompasses portions of present-day New Mexico, utilized travois dragged by canines (later substituted with equine species) for transporting their dwellings, household items, and personal belongings during initial interactions with European settlers roughly five centuries ago. According to research findings, young individuals and elderly females were known to travel within these structures as well. The investigators inferred from the dimensions and arrangement of historic foot impressions discovered adjacent to the trail marks that adult members probably hauled the travois, trailed closely behind by younger ones.

" numerous individuals might recognize the experience of maneuvering a shopping cart through a grocery store, shifting from one area to another with kids clinging onto it," according to the study’s lead author. Matthew Bennett , a professor specializing in environmental and geographical sciences at Bournemouth University in the UK, stated in an interview statement This seems to be the early version, though lacking wheels.

Related: The first Americans turned out to be different from what we believed.

Bennett observed that researchers understand our forebears had to use some method for transporting their belongings during global migrations; however, such wooden devices have long decomposed over time. These newly found scrape marks offer the initial evidence of how ancient humans shifted bulky items. before wheels , he said.

In 2020, researchers initiated the excavation of the drag marks site at White Sands. Here, trackways are embedded within layers of ancient dried mud that lie underneath sediments. Thousands of years ago, humans walked across this area. trudged through this landscape beside woolly mammoths, enormous ground sloths, camels, and numerous other species ice age creatures.

The scrape marks include lines in the soil stretching over 165 feet (50 meters) upwards. These marks sometimes consisted of individual lines, potentially created by two poles tied together at one end forming an A-shape. Alternatively, some instances featured two parallel lines, presumably resulting from two poles intersecting in the center to form an X-shape, as stated in the report.

The Indigenous peoples of the Great Plains commonly employed an A-frame structure featuring wooden beams connected either by crossbars or woven baskets designed to secure items, as indicated by the research. Investigators posited that early inhabitants of this area utilized similar contraptions. In order to validate their hypothesis, they constructed travois using wood poles and pulled these structures across muddy flats in the United Kingdom and coastal areas of Maine for testing purposes.

"In our experiments, the imprints and mud trails from the poles looked identical to the fossilized specimens we discovered in New Mexico," Bennett stated.

Bennett and his colleagues previously dated The human footprints found at White Sands date back approximately 21,000 to 23,000 years ago—this challenges the earlier belief that humans first arrived in North America between 13,000 and 16,000 years ago. While not all scholars concur with this timeline for the site, the study’s authors emphasized that regardless of the exact timing, these recently discovered traces highlight early Indigenous activities. Any discussions about the dates should not overshadow the significance of uncovering evidence related to ancient Native American traditions.

Each finding we reveal at White Sands enhances our knowledge about the individuals who were among the earliest inhabitants of the Americas, according to the co-author of the recent research. Sally Reynolds A mammalian paleontologist at Bournemouth University stated in the release, “These individuals were the initial explorers to journey to North America. Gaining insights into their movements is crucial for accurately narrating their history.”

Mammoths, Bison, and Rhinos: Hidden Prehistoric Masterpieces of French Cave Art Revealed

Hundreds of depictions of ancient creatures and females adorn the walls of a cavern in southwestern France. Each year, for four weeks, scientists are granted access to document this site.

In the depths of a winding cave located in southwestern France, early humans from approximately 30,000 years ago etched images of horses, mammoths, and rhinoceroses onto the walls, revealing an extraordinary collection of Ice Age creatures seldom witnessed before this point.

Found in 2000 by an amateur spelunker, the Grotte de Cussac located within the Dordogne region houses old human remains, remnants of extinct bears, along with delicate and remarkable artwork which those who protect this site strive diligently to safeguard.

Usually, the French authorities limit entry to the cave for researchers, who are permitted to access it only during a four-week period each year.

The authorities are eager to prevent a recurrence of the damage inflicted on France. Lascaux caves By microorganisms carried in by visitors.

The Lascaux caves, situated in Dordogne as well, have artworks believed to be several millennia more recent than those found at Cussac. They were shut off from the public in 1963 to preserve their valuable murals.

The Cussac cave is accessed via a narrow passage through boulders that have closed off its inner chambers for thousands of years.

Guided by the beams from their headlamps, tourists traverse expansive caverns filled with stalactites and stalagmites, treading the same slender route as Marc Delluc, the late amateur spelunker who unearthed this grotto in September 2000.

In 2017, Delluc passed away after noticing an air current emanating from the crevices in the stones. He navigated through the limestone and discovered a pathway approximately 100 meters (110 yards) long that led to the carvings.

It was likely sealed shortly after being inhabited, thereby safeguarding the soil and remnants within.
Emeline Deneuve from the cultural affairs division of the Nouvelle-Aquitaine region

He recounted the "surge of excitement" he experienced upon spotting the curved shapes and outlines etched into the stone above him.

He mentioned how he recognized the privilege bestowed upon him, allowing access to a site sanctified since antiquity.

The cave, extending for 1.6 kilometers (1 mile), features over 1,000 carvings of various creatures and abstract female shapes.

Researchers have determined their age to be between 26,000 and 35,000 years old, corresponding to the era of the ancient Gravettian culture in Europe.

The Grotte de Cussac stands out due to its excellent preservation. It likely became sealed shortly after being inhabited, thus safeguarding the contents within from disturbance,” stated Emeline Deneuve, who leads heritage conservation efforts at the cultural affairs division of the Nouvelle-Aquitaine region’s government.

Scratch marks and indications of digging suggest that it was also utilized by cave bears, which were prehistoric ancestors of the brown bear.

Within their cryopreservation pods, scientists discovered the remnants of six human bodies, which date back to the same era as the carvings.

According to Jacques Jaubert, the site’s lead archaeologist, this is the sole known instance where a cave was utilized by ancient humans for both interments and artwork.

He stated that the location served as a "safe haven" rather than a place of residence. The collective chose to live outdoors, either in exposed areas or beneath rock formations for shelter.

Jaubert believes the cave might have served as a site for initiation rituals, "a transition ceremony for teenagers to enter adulthood," which is a custom frequently seen among early hunter-gatherer communities.

He mentioned that it would also be viewed as "a transitional space between the realm of the living and the domain of the deceased".

The carvings, referred to as "pieces of folklore" by him, were created using materials like flint, wood, and bone.

They portray bison, ibex, geese, and various other creatures, along with women who are frequently shown with oversized heads and minuscule feet.

"Following the examination of the cave’s walls, where he left marks using his fingertips, the artist etched initial depictions of animals. These were later supplemented with additional layers of images," explained researcher Valerie Feruglio, who employs 3D imaging techniques to analyze these works of art, aiming to unravel their narratives.

The cave remains unexplored to this day.

However, the authorities are very careful about safeguarding the location, designated as a historic monument back in 2002.

"Deneuve, who leads conservation efforts, stated, 'We are the custodians tasked with safeguarding and recording this site,' " he mentioned.

We back the research conducted there, provided it aligns with conservation and heritage standards. Our aim also includes documenting the cave and creating a 3D digital version to make it accessible to everyone.

In October, a complimentary exhibition showcasing the cave was unveiled in Buisson-de-Cadouin, a commune located in France’s Dordogne region, featuring replicas of its artistic wonders.

However, officials state that there are currently no intentions to make the cave accessible to the general public.

Minat Merawat Burung Kakatua? Ketahui Syarat dan Tipsnya Sebelum Mulai

, Jakarta - Bagaimana mungkin seseorang tidak iri saat melihat burung? kakatua , dengan keindahan warna serta kemampuannya menggiring suara manusia? Jika Anda ingin merawatnya, berikut adalah hal-hal penting yang harus dipertimbangkan.

Walau terlihat menggemaskan berkat bulu yang menawan dan suaranya yang imut, Dr. Amelia Baldwin, seorang dokter hewan dari Rumah Sakit Hewan Ekotik di Chicago, AS, memberi peringatan kepada mereka yang tidak memiliki pengetahuan tentang merawat hewan tersebut. burung Dan menginginkan seekor kakatua. Lagipula terdapat lebih dari 300 spesies burung ini di seluruh dunia.

"Burung ini kurang cocok untuk pemula yang baru mengurus hewan. Kakatua memerlukan perawatan intensif serta rangsangan mental yang cukup," jelas Baldwin kepada USA Today edisi 14 Maret 2025.

Kakatua Butuh Ketelatenan

Baldwin menyebut bahwa merawat kakatua cukup rumit lantaran hewan tersebut membutuhkan paling tidak lima jam per hari untuk pelatihan serta interaksi bersama manusia supaya dapat bertahan dengan cara alamiah. Selain itu, burung ini cenderung membuat tempat tinggal menjadi kotor dan memiliki kulit yang ekstremis terhadap sentuhan.

Klinik di mana Baldwin berpraktik merekomendasikan untuk meletakkan kakatua dalam kandang yang luas sehingga tidak mencegah gerakan sayapnya ketika dia menyebarkannya. Bagian dalam kandang perlu dilengkapi dengan tiang vertical buatan baja tahan karat serta posisikan kandang tersebut di ruangan dengan kontrol temperatur optimal dan tanpa adanya asap.

"Berpikirlah, jalur pernafasannya sangat peka terhadap stimulus. Jangan gunakan lilin, semprotan, atau perlengkapan memasak non-antilengket," nasihat Baldwin.

Oleh karena itu, hindari meletakkan sangkaran di sekitar daerah dapur atau biarkan burung berkeliaran di sana, terutama jika ada uap dari peralatan memasak yang bisa saja berbahaya serta risiko burung bersentuhan dengan kompor yang masih panas. Klinik Burung dan Hewan Eksotis di Long Island juga mencatat bahwa kakatua cenderung sangat suka kotoran dan sering menyimpannya dalam sangkar mereka. Sebagai akibatnya, klinik lain di New York merekomendasikan pembersihan harian agar tetap menjaga kebersihan sangkar.

"Harusmembersihkansangkarsecaramatamdilakukantidaksedikitsekaliseminguataulebihseringlagi,tergandungsampondankebersihanburung.Pastikankamuembersikhiseksilerjeruyangi,danmainanyangada,komadanlubangsudutyangbermasalahsepertisketandanbekas-makana,"tulisnyadiklinaikketersebut.

Perhatikan Makanannya

Seputar pemberian makanan, Baldwin serta dokter hewan lainnya merekomendasikan untuk memberikan burung cakakailu dengan pelet bersama dengan camilan seperti buah dan sayur yang masih segar. Di klinik Pender Exotics di Fairfax, Virginia, mereka menegaskan agar tidak memberinya alpukat ataupun makanan yang memiliki kadar garam, gulanya terlalu tinggi, atau banyak lemak. Mereka juga mendesak pemilik jangan sepenuhnya mengandalkan jenis makanan beras butir ini sebab dapat membawa risiko obesitas dan kurangnya asupan vitamin.

"Berbagai macam biji-bijian ditawarkan sebagai sumber vitamin; meskipun demikian, vitamin ini hanya terdapat pada lapisan luarnya saja dan akan ikut terbuang ketika burung membuka cangkangnya untuk memakannya. Tidak apa-apa apabila Anda menyediakan biji-bijian dalam pemberian makanan mereka tetapi pastikan tidak melebihi 15-20% dari total asupan harian burung," tambah klinik tersebut.

Walaupun perawatannya kompleks dan tidak murah, Baldwin menyebutkan bahwa kakatua tetap menjadiilihan. hewan peliharaan Jika Anda ragu tentang di mana harus mencari atau membeli, cobalah mengunjungi tempat penampungan atau pusat penyelamatan untuk burung-burung kakatua liar. Apabila Anda takut bahwa usia burung tersebut mungkin melebihi masa hidup Anda sebagai pemiliknya, pertimbangkanlah untuk memilih seekor kakatua yang sudah berumur lanjut.

Zweedse hondenrassen: Originele tophonden en hardwerkende loophonden

Hoog in het noorden, waar elanden, lynxen en beren door het ongerepte landschap zwerven, zijn negen prachtige Zweedse hondenrassen ontstaan. Lees verder om erachter te komen welke hondenrassen bij het grootste Scandinavische land horen en wat hen kenmerkt.

Zweedse hondenrassen worden gekenmerkt door hun robuustheid en bereidheid om te werken. Veel van hen werden gebruikt voor de jacht op Zweedse wilde dieren of voor het hoeden van kuddes. Een dikke vacht met ondervacht was ook een voordeel bij het werken in het soms polaire klimaat van Zweden.

Vanwege hun zeldzaamheid moeten liefhebbers van de FCI-erkende Drevern, de Zweedse Lapphund en co. veel geduld hebben bij het adopteren. Kennis van het oorspronkelijke gebruik van de hondenrassen is ook nuttig.

In de zeldzaamste gevallen kunnen de Zweedse viervoeters een leven in de stad en in een flat aan.

Scandinavische honden zijn buitenmensen die in het beste geval een groot stuk land tot hun beschikking hebben.

Kortom, ze zijn geschikt voor een heel speciale groep hondenliefhebbers. De lage verspreiding van Zweedse hondenrassen heeft echter één groot voordeel: Je zult in het Noord-Europese land tevergeefs zoeken naar overgefokte viervoeters.

De “dwerg” onder de Zweedse jachthonden: De Drever heeft een schouderhoogte van 30-38 cm. Zijn kleine formaat is geen toeval: hij is het resultaat van een kruising tussen de kleine Westfaalse Dachsbracke en lokale jachthonden.

Als zijn gezin hem puur als gezelschapshond ziet, zal de Drever snel verveeld en gefrustreerd raken. Hij wil immers zijn grote werklust en zijn uitstekende jachtinstincten bewijzen. Daarom is de Drever in Zweden bijna uitsluitend thuis bij jagers.

Gotlandstövare

Zeldzame schoonheid: de Gotlandstövare is zelfs in zijn thuisland uiterst zeldzaam. Het is een middelgrote jachthond die speciaal werd gebruikt voor de hazenjacht.

In de 17e en 18e eeuw namen Zweedse troepen jachthonden mee naar huis. De Oost-Europese en continentale jachthondenrassen speelden een doorslaggevende rol in de ontwikkeling van dit hondenras.

Uiterlijk is de viervoeter gemakkelijk te herkennen. Zijn vachtkleur is meestal geel, maar geelrood met witte aftekeningen is ook toegestaan.

Hamiltonstövare

Driekleur: De Hamiltonstövare heeft een zwart-witte vacht en is een gepassioneerde jager. Om precies te zijn is het een robuuste jachthond die gespecialiseerd is in de jacht op hazen en vossen. Zijn voorouders zijn Duitse jachthonden en windhonden, evenals de kiekendief en de Fox terriër.

De speelse viervoeter is vernoemd naar graaf Adolf Patrick Hamilton. De naamgever was een jager en hondenfokker en presenteerde voor het eerst een reu en een teef op een Zweedse hondenshow in 1886.

Jämthund

De Jämthund vergezelt mensen al sinds de kolonisatie van Noord-Zweden bij de jacht op elanden. Hij staat ook bekend als de “Zweedse Elandhond”. Maar ook andere wilde dieren zijn niet veilig voor hem. Zijn veelzijdige jachttalent en robuuste lichaam zijn net zo gewild bij de jacht op beren en lynxen.

Dankzij zijn achterdochtige karakter slaat de viervoeter, die tot 30 kg kan wegen, ook een goed figuur als waakhond . Belangrijk om te weten: De Jämthund is niet voor beginners. Zijn sterke persoonlijkheid vereist mensen met hondenervaring.

Norrbottenspets

Als we het hebben over oude Zweedse hondenrassen met een opmerkelijke robuustheid, dan is het de beurt aan de Norrbottenspets Volgens de weegschaal wegen ze niet meer dan 10 kg. Hoewel hun kleine postuur erop kunnen wijzen dat zij niets waard zijn, mogen zij zeker niet ondergewaardeerd worden. In het verleden hielpen zij jachtgezellen bij de Noordkaap door hen te begeleiden tijdens de jacht, op jagt uit te gaan en molentjes op te sporen.

De grauwe Spitz afkomstig uit de nordeurkoude streken is behendig en kent een passie voor meerdere canine-activiteiten. Het dient eveneens te worden vermeld dat deze hond soort een tamelijk onafhankelijke karakter heeft en vroegtijdige sociale interacties nodigt.

Schillerstövare

De Schillerstövare Zijn naam wordt gegeven aan hem door zijn fokker Per Schiller. Het Zweedse hondenras heeft zich gevormd uit meerdere loophonden afkomstig vanuit Groot-Brittannië en Zwitserland. In het jaar 1907 kreeg deze aktieve en jacht-liefhebbende vierpotige erkenning bij de Zweedse Kennel Club.

Zijn kenmerk: de Schillerstövare jaagt nooit in groepen, maar steeds solo - desondanks geldt hij als verenigbaar en sociabel met andere honden. Toch moet men voorzichtig zijn met katten: Zijn prooidrangschikking maakt het delen van huis met katten buitengewoon moeilijk.

Zweedse Lappenhond

De Zweedse Lappenhond Hoort bij de categorie "Skandinavische wacht- en korthoringsschachten" en was vroeger ingezet voor het bewaken van rendieren. Tegelijkertijd behoort dit ook tot de groep die... Finse Lappenhond Het wordt gezien als het originele hondenras dat de ouder is van alle Spitz-rassen die zich langs de kusten van de Balzische Zee hebben ontwikkeld.

De vroegere werkzwijnpuppent die nu in zijn geboorteland steeds meer fungeert als gezelschapsdier en familiehond. Het evenement kent een verscheidenheid aan activiteiten zoals honden-dansewedstrijden, fietsen en nog vele andere dingen waar kindvriendelijke schoothondjes bij betrokken raken.

Smålandstövare

Als de Smålandstövare Zodra hij een geur opsnuift, blaft hij direct hard om het alarmerend kenbaar te maken. Dit is immers zijn functie; de Zweedse vierpotige speurhond staat bekend om zijn jachtprestaties op vossen en wilde herten. Zijn rauwe, strakke vereniging van vachtlaag en ondervacht functioneert als bescherming tegen de kille Scandinavian windstoten.

Ondanks zijn onafhankelijke karakter kan hij gemakkelijk als gezinshond worden gehouden. Hij heeft echter elke dag lange wandelingen en speelsessies nodig om hem mentaal en fysiek bezig te houden.

Västgötaspets

Wolf in het klein: Met zijn wolfachtige vacht doet de Västgötapets denken aan de voorouder van alle huishonden. Het bevat echter ook de kortbenige Welsh Corgi. Men gelooft dat Vikingen ooit het Engelse hondenras naar Zweden brachten en dat het een belangrijke rol speelde in de fokkerij.

In dit land staat de kleine hond ook bekend als de Zweedse Vallhund of Visigoth Spitz. Ondanks zijn kleine formaat kan hij gemakkelijk grotere dieren hoeden. Veel moed en een zekere vasthoudendheid zijn een voordeel bij deze veeleisende taak.

Australian Politician Slams Trump's Tariffs as 'Dog Act': The Insult's True Meaning and Offense Level Explained


categories: , , ,

Caitlin, this week Australia's Industry Minister, Ed Husic, referred to President Donald Trump's tariffs on aluminum and steel a “dog act” . I hail from New Zealand, a nation closely linked to Australia but blissfully untouched by the term "dog act." Could you explain—what exactly does this expression signify, and is there truly any connection to canines?

Your country has failed to receive a genuinely harsh criticism.

Even though this expression includes the term "dog," it isn’t related to our faithful four-legged friends at all. While we typically view dogs as loyal, gentle, and obedient creatures—I must admit, being a devoted Labrador parent—when someone refers to an action as a "dog act,” they mean something deceitful, spineless, and entirely inappropriate.

That’s according to Oxford University Press which designated "Dog Act" as their word of the month for September way back in 2018.

Even though this expression has become a typical insult in everyday Australian speech, it does not have an extensive history. The Oxford University Press discovered the earliest usage of the term in a 2003 article from The Sydney Morning Herald.

Intriguing. If somebody said you performed a "dog act," how upset would you reasonably feel?

You ought to feel completely shocked. A "dog act" doesn't just involve messing with somebody's composure or grabbing a snack right out of an innocent person's hand without them noticing (in this case, referring to the mentioned Labrador). Instead, a "dog act" challenges a person's honesty. It represents a breach of trust.

That's likely why it frequently appears in sporting or political settings, where loyalty is treated like sanctity. Each fortnight, AFL or NRL athletes face accusations of committing "dirty plays," taking "unsportsmanlike shots," or delivering "rough tackles" during matches.

In the words of one Reddit user When I refer to you as a dog, I'm not talking about an animal that moves on four legs and barks. Instead, I'm referring to what I consider the most despicable beings on this planet.

I've come across "raw-dogging" and "dogging." Is this related to those practices?

Fortunately, a "dog act" doesn’t have any sexual undertones, unless maybe you're being unfaithful to your partner.

You're not playing the role of a peeping tom or a voyeur. You’re also avoiding unprotected sex or engaging in similar activities. a more contemporary understanding of the phrase "having coffee black," consuming caffeine sans milk or completing a nine-hour journey with only the flight map for amusement.

In Aussie slang, referring to someone as a "dog" can be quite insulting by itself. Change it to "dogging," however, and it transforms into a noun — the action of behaving like a dog by backstabbing or disappointing others. The key factor remains the way you say it.

Okay, I believe I'm getting it. Given these conditions, which additional Aussie expressions should I know about?

Get ready. This isn't the first instance of an Australian politician using local lingo to upset their overseas colleagues.

In 2014, former Prime Minister Tony Abbott created mayhem (along with bewilderment) when he threatened to "confront" Vladimir Putin When the Russian president came to Down Under – referring to performing a frontal chest bump or similarly robust greeting. It was noted as being "rather uncommon." by a Russian diplomat .

However, there are numerous additional Australian slang terms that can be used based on the situation. If someone is acting foolishly, you might use "drongo," "dingbat," or "dipstick." To be particularly harsh, you could say "flog," and for a condescending remark, "OK champ" works well.

Next up is my personal favorite, expressed with a straight face and directly meeting someone's gaze: "Yeah, righto, mate." I'm eager to hear this used by an Australian politician sometime soon.

Top 10 Shark Myths You Need to Stop Believing Now


categories: , , , ,

Sharks are cold-blooded killers

"[A lot of individuals believe that] sharks are intent on harming humans and will 'assault' as soon as our little finger touches the water," explains shark scientist Blake Chapman, PhD, who authored Shark Attacks: Legends, Confusions, and Human Fears “. Yet, each year, millions of individuals swim near sharks without being aware of their presence, and the majority remain unscathed. Only an extremely small number of people experience adverse interactions with sharks." Actually, these 22 creatures pose significantly lesser risks than commonly perceived." more dangerous to humans than sharks .

They acquire a preference for consuming human meat.

Experts concur that many unprovoked shark bites often appear to be exploratory—"What's this here? Could it be food?" Those large, assertive sharks known for feeding on seals and other sea mammals such as great whites, bulls, and tigers fall into this category. those most prone to biting individuals According to the National Geographic Society, as highlighted by the National Ocean Service, sharks have been evolving for hundreds of millions of years prior to human existence; hence, we are not included in what they naturally eat . The majority of sharks primarily feed on smaller marine life such as fish and squid. To provide further assurance, consider these additional points: comforting—and fascinating—facts about sharks .

Female sharks require males to reproduce.

Some female sharks possess the power of parthenogenesis —The capability to fertilize their own eggs and produce offspring without a male shark. This phenomenon is typically observed in plants and insects such as wasps, ants, and bees.

Dolphins scare sharks.

You might have come across the belief that spotting dolphins in the water indicates it’s "safe" to swim since sharks would likely be far away. However, this notion about sharks and dolphins isn’t accurate. frequently sail through the same areas Due to their similar diets, which include schooling fish, squid, and crustaceans, as reported by the Sarasota Dolphin Research Program, both creatures often compete for food sources. Additionally, they can be predators of one another; dolphins may consume smaller shark species, whereas larger sharks have been observed attacking dolphins.

Every shark species is identical.

Sharks often receive negative attention, yet they come in more than 500 distinct varieties—every one uniquely different," explains Dr. Chapman. "These creatures stand out as real survivors and masters of evolution. Each shark type has evolved with remarkable precision for specific environments, dietary requirements, methods of locating food and partners, and even strategies to evade threats. Consequently, you won’t find just a single 'shark.' Rather, we have over 500 extraordinary species worthy of discovery.

Although many shark species develop considerable size and possess sharp teeth, the biggest ones such as whale sharks and basking sharks often reach lengths of around 40 feet but remain harmless to people. Additionally, numerous small shark varieties also exist; the dwarf lantern shark is minuscule enough to rest in an outstretched human palm, whereas coral catsharks seldom exceed two feet in length, which makes these creatures particularly favored choices for private fish tanks. Nonetheless, there does exist One kind of shark you'll find never see in an aquarium.

Sharks have no predators

As mentioned earlier, dolphins occasionally consume small sharks. Furthermore, orcas—the biggest species within the dolphin family—do this as well. assault and prey upon great whites According to the Sarasota Dolphin Research Program, but the greatest danger to sharks comes from humans. Studies indicate that humans slaughter approximately 100 million each year Unfortunately, declining shark numbers could potentially harm the ocean ecosystem—as these top marine predators are crucial for our seas.

Shark nets effectively safeguard swimmers.

Australia ranks second globally for unprovoked shark attacks, following the United States, as per research conducted by Dr. Chapman along with her co-author Daryl McPhee, Ph.D., who is an environmental science associate professor at Bond University. The majority of these incidents occur off the coast of New South Wales, reports the International Shark Attack File (ISAF). To safeguard swimmers and surfers, the Australian government has implemented various measures. has conducted tests of shark nets in the region For numerous years, people have aimed to capture aggressive shark species like great whites and bull sharks, which are most prone to human interactions. However, during this time, countless other creatures—including several that are threatened—have ended up ensnared in these traps. During a particular five-month span, among the total of 145 animals captured, Only two were targeted as shark targets. According to media reports, the majority of creatures ensnared in these nets do not survive.

If sharks cease swimming, they will perish.

Sharks possess multiple gill slits on either side of their heads—while swimming, water enters through their mouths and passes over their gills, with the gills extracting oxygen from the water. Great whites, makos, and whale sharks rely solely on this method for respiration. They must continuously swim to obtain oxygen. According to the Smithsonian Institution, this applies to some species. However, numerous others have the ability to draw water into their mouths and direct it across their gills without moving, even when stationary. This includes nurse sharks, angel sharks, as well as the uniquely shaped tasseled wobbegongs.

Shark fins possess therapeutic benefits.

Shark fin soup is considered a luxury dish in China and has historically been thought to offer various health advantages. However, contemporary researchers highlight that shark flesh, particularly from their fins, often contains dangerously high levels of mercury and other harmful substances. Additionally, extensive shark hunting, largely driven by demand for these expensive soups, leads to the death of as many as One hundred million animals annually , putting numerous distinct species at risk and potentially jeopardizing the entire marine ecosystem.

If you get bitten by a shark, your chances of survival aren’t good.

You have more than double the chance to perish due to a lightning bolt Shark bites occur less frequently than many might think, as noted by the Florida Museum’s International Shark Attack File (ISAF). Moreover, even when an attack does happen, "most individuals manage to survive," states Dr. Chapman. In 2018 globally, there were just 66 unprovoked shark attacks recorded, with merely six proving lethal, based on the same file.

What to Do If a Coyote Visits Your Yard: Expert Tips

According to two experts.

Coyotes are intriguing animals that were not originally present east of the Mississippi River. Over approximately the past hundred years, though, they've extended their territory throughout North America. "This expansion might be attributed to alterations in habitat and also because competing species like the eastern red wolf have been eliminated from the environment," explains Michel Kohl, PhD, who is a Certified Wildlife Biologist, wildlife extension specialist, and an associate professor of wildlife management. University of Georgia They're among the scarce big meat-eaters found in North America, and they thrive even when living near humans.

Although you might believe identifying a coyote ( Canis latrans While coyotes might seem unusual in your area, they're actually quite common. "Coyotes can adjust to nearly any habitat they encounter," explains Sheldon Owen, PhD, who serves as a wildlife extension specialist. West Virginia University Even in an urban environment, they create their own space.

The highest danger posed by coyotes is that they can carry diseases These diseases that can be transmitted to both humans and pets include conditions like canine distemper, parvovirus infection, as well as pests such as fleas, ticks, and mites responsible for causing mange. Similar to other mammalian species, coyotes may also contract rabies; however, this occurs infrequently with less than 1.5% of all wildlife rabies instances being linked to them.

Typically, coyotes do not pose a problem for residents. prefer to avoid us The most frequent complaint we receive regarding coyotes is when people say, 'I spotted a coyote in my backyard,' " explains Owen. "This can pose problems, particularly for those with tiny pets. However, the majority of these potentially adverse encounters can be avoided.

Identifying Coyotes

Similar to domestic dogs in taxonomy, coyotes can appear like them when seen from afar. Indeed, they're comparable in size to an average-sized dog, typically weighing around 30 to 35 pounds and standing approximately 36 inches high at their shoulder blades. These animals look quite slim with a thick furry tail carried at a slight downward slope, according to Owen.

The coloration of coyotes can vary from dappled gray to reddish hues or even completely black. According to Kohl, in southern regions, you'll find a greater number with entirely black fur. They typically display peak activity around twilight hours; however, spotting one during daylight isn't uncommon and shouldn't automatically imply they're infected with rabies, as stated by Kohl.

Groups might include a breeding couple along with several juvenile offspring. You have the highest chance of spotting coyotes during spring as the pups learn hunting skills, and in autumn when adolescents leave to establish their territories, according to Owen.

It’s equally likely that you might hear them at nighttime instead of spotting them. Coyotes use vocalizations to protect their territory and communicate within packs. They possess one of the most intricate and diversified sets of sounds among animals. "What seems like a chorus of coyotes could just as easily be from a pair or trio," explains Kohl.

Understanding Coyotes

Coyotes possess a remarkable knack for adjusting to various environments and boast a flexible diet. Although they prey on smaller creatures like rabbits, mice, voles, and occasionally even small dogs and cats, these adaptable animals will consume carrion, pet food, garbage, along with fruits, grasses, and plants according to Kohl’s observations. Typically seen alone during hunts or scavenging activities, coyotes may form packs at times to take down larger game.

Coyotes mate from late winter through early spring, resulting in litters usually born in late spring, each containing around five pups on average. These coyotes make their dens beneath fallen trees, within dense shrubbery, or among rocky outcrops. Generally, they prefer not to establish these dens near human settlements; this preference also applies to other wildlife species akin to them. groundhog or raccoon They might take place beneath a shed or within a crawlspace. The size of their territories can vary based on food competition; these creatures typically claim several square miles in an urban environment and a bigger area in a more rural location.

How to React When Spotting a Coyote in Your yard

The majority of unpleasant encounters with coyotes can be prevented by adhering to these guidelines provided by Kohl and Owen:

  • Keep in mind that coyotes are a natural part of our environment, including urban areas. As coyotes extend their range, you might find them in your yard or garden. "Be conscious of the possibility that they could be present, even within a suburban environment," advises Owen.
  • Ensure your dog remains leashed while walking, particularly during early morning and late evening hours. Kohl states that coyotes may target small dogs, but attacks on medium and large dogs typically do not occur frequently.
  • Keep an eye on your pets when they're outside, even within a fenced space. Owen mentions that coyotes are skilled at climbing and can easily climb over a six-foot fence.
  • Prevent cats from wandering around. According to Kohl, research indicates that both domestic and feral cats serve as prey for coyotes.
  • Avoid leaving pet food outdoors. Similar to various forms of wild animals, like raccoons , opossums, and skunks Coyotes enjoy a effortless dinner and will swiftly figure out where they can get one, according to Owen.
  • Ensure that trash cans and compost bins remain closed. So they aren't used as food sources, according to Owen.
  • Make sure your pets have current medication schedules. This encompasses preventative measures for fleas and ticks And heartworm along with vaccinations for parvo, distemper, and rabies, according to Kohl.
  • Ensure that chicken coops and farm animals are safeguarded. If utilizing fencing, an electric wire At the top and bottom of fencing, adding certain features can deter coyotes without causing them harm, according to Owen.
  • Employ hazing methods to deter a coyote from your property. Should a coyote wander into your vicinity, try banging pots and pans together, shouting loudly, or using an air horn to frighten it away; they generally tend to be timid and will retreat. Alternatively, employing a motion-activated water sprinkler could prove effective too. "Our aim," states Kohl, "is to maintain their fear of humans."
  • Disregard sprays and essential oils. According to Owen, these methods are of dubious or no efficacy. Actually, the coyote might simply urinate on any odor deterrents you apply.
  • Reach out to your state’s local wildlife agency if you have worries regarding a recurring visitor. If your livestock or poultry keep vanishing, if you often spot a coyote around your land, or if you come across one that appears unafraid of people, removal might be necessary. "When you shout at a coyote and it remains unfazed, staring back at you, this is not something we should allow," warns Kohl.

Can Coyotes Assault My Dog?

Although interactions between pets happen from time to time, their results tend to be inconsistent and hard to predict. Coyotes usually target small dogs, whereas assaults on medium-sized or larger dogs are relatively rare. "In the canine social structure, dominance plays a crucial role; hence, coyotes often bully smaller dogs yet generally avoid attacking bigger ones as they realize such confrontations would likely end unfavorably for them," explains Kohl.

When individuals report that a group of coyotes has attracted a big dog deeper into the forest, it’s often because the dog was asserting territory and pursuing the coyote. Nevertheless, after the dog ventures into the woodland, the other members of the coyote pack typically step in to protect their own, as stated by Kohl.

Are Coyotes Dangerous?

Usually, coyotes tend to avoid humans. "However, this can vary based on their past interactions with people," explains Kohl. "Even though incidents where coyotes attack humans are uncommon, these cases often stem from someone having fed a coyote, causing the animal to get accustomed to human presence."

If you see a coyote, it's probably just traveling through and isn't interested in you.

"The primary danger coyotes present to us is the possibility of transmitting diseases to our pets," explains Kohl. To safeguard your animals, ensure that all their vaccinations are current and consistently apply treatments to shield your pets from heartworms, fleas, and ticks.

Brown Bear Emerges From Semi-Hibernation After Pioneering Brain Surgery

A brown bear that received groundbreaking, lifesaving brain surgery in October has come out of partial hibernation looking fantastic, happy, and healthy.

The three-year-old Boki, residing at Wildwood Trust close to Canterbury in Kent, has been experiencing seizures thought to be due to hydrocephalus (fluid accumulation on the brain).

He was treated with prednisolone for the inflammation and excess fluids, however, zoo personnel wouldn’t have been able to provide care after he entered torpor (a state similar to hibernation).

The decision was made that brain surgery would be the most suitable choice for Boki, leading him to undergo an operation lasting five hours on Wednesday, October 9. This procedure marked his status as the first documented brown bear to receive such treatment.

The renowned veterinarian Romain Pizzi, who did not charge for his services, implanted a stent connecting Boki’s brain and abdominal area to facilitate the drainage of surplus fluids.

A representative from Wildwood stated that the bear has shown "extraordinary recuperation" and was gradually taken off his medication without experiencing any negative side effects shortly before entering hibernation.

Jon Forde, who leads the bear care team at Wildwood, mentioned that Boki coming out of partial hibernation marks an important phase in his rehabilitation process.

He stated: "He looks fantastic, joyful, and fit; we have not noticed any adverse indications from him. All of his character attributes remain intact—he's still the beloved Boki we know and care for."

Boki performed admirably during his inaugural hibernation. He shed approximately 30 kilograms—likely due to significant growth occurring while he slept, which consumed considerable energy.

Our initial task will be to help him gain some weight. This season, food isn’t abundant—primarily just plants. We'll work on getting his weight up gradually, proceeding slowly to ensure everything goes well and confirm without any doubt that he’s in good health.

Boki was taken in by Port Lymphe Wild Animal Park in December 2022 when he was abandoned by his mother and needed to be raised manually by the staff members.

The spokesperson stated: "The group from Wildwood, famous for their efforts with brown bears, assisted him in understanding bear behaviors. During this process, they started integrating him with their two mature bears—Fluff and Scruff."

This must end due to his seizures, but the hope is that they'll come together again before long.

Mark Habben, Wildwood's head of zoo operations, stated: "We've witnessed quite an amazing change in this young bear; he has returned to his former self – just like the Boki we initially encountered. It seems as though he doesn’t recall having undergone surgery at all."

“Even though the indicators are quite promising, we must still move cautiously and ensure careful reintroduction for Fluff and Scruff.”

This will include rowdy play, something we aim to reduce during these initial phases after emerging from torpor.

“We will monitor him very closely and, at some point over the coming months, we will conduct that introduction if everything continues to go well.

“We have to take this step for his wellbeing and theirs as well – they want to be together.”
