                    <title>Seals and sea lions provide clues to evolution of vocalization</title>
                    <description>Neuroscientists have uncovered new insights into a key evolutionary question: Why can humans talk when most animals can&#039;t? The journal Science published the research led by Emory University and the New College of Florida. The findings suggest that seals and sea lions may have vocal flexibility as a side effect of developing a brain &quot;bypass&quot; for voluntary breath control. This same bypass allowed them to adapt to aquatic life.</description>

                    <description>Their icy hunting grounds are rapidly shrinking, but polar bears in Norway&#039;s remote Svalbard archipelago have defied the odds by bulking up instead of wasting away, a study said Thursday.</description>

                    <description>Arctic sea ice has large effects on the global climate. By cooling the planet, Arctic ice impacts ocean circulation, atmospheric patterns, and extreme weather conditions, even outside the Arctic region. However, climate change has led to its rapid decline, and being able to make real-time predictions of sea ice extent (SIE)—the area of water with a minimum concentration of sea ice—has become crucial for monitoring sea ice health.</description>

                    <description>The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations of polar bear population declines coinciding with sea ice loss across the Arctic.</description>

                    <description>The ancestors of our furry cats and dogs once looked similar to today&#039;s modern mongoose, a mammal with a long body and small, round ears. In fact, all members of the order Carnivora, which includes a variety of mammalian species, such as bears, wolves and even seals, evolved from these &#039;mongoose-like&#039; creatures.</description>

                    <description>In the animal kingdom, penises can be spiked, split, corkscrewed—even detachable. They&#039;re one of the most diverse structures in biology. The human penis is so uniform, it&#039;s an anatomical outlier. Understanding why penises evolved, and why they differ so widely, also helps explain why humans have one at all.</description>

                    <description>A new paper by University of Rhode Island post-doctoral researchers Emily Sperou and Renato Borras-Chavez published in the journal Polar Biology discusses a unique phenomenon observed in a reclusive Antarctic animal: postmortem attentive behavior, or PAB, in the solitary leopard seal. The two are members of URI&#039;s CEAL Lab in the Department of Natural Resources Science.</description>

                    <description>As the Arctic warms faster than anywhere else on Earth, animals that have evolved to survive the cold face unprecedented challenges. While scientists are learning more about how modern wildlife responds to environmental change, we still know little about how species coped in the past.</description>

The research, led by British Antarctic Survey (BAS) scientists in partnership with The Alan Turing Institute, WWF and the Government of Nunavut, demonstrates how this technology could assist local agencies in protecting critical migration routes which cross areas of land and sea ice.</description>

                    <title>Assessing the sustainability of the Pacific walrus population over the next 75 years</title>
                    <description>The Pacific walrus, a critically important resource for Alaska and Chukotka Native communities, is subject to rapid habitat loss associated with climate change and increasing human activity in the Arctic. New research published in The Journal of Wildlife Management assessed the sustainability of varying degrees of Pacific walrus harvest to the end of the 21st century under different climate and human disturbance scenarios.</description>

                    <description>By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trading ivory in remote parts of High Arctic Greenland, several centuries before Christopher Columbus &quot;discovered&quot; North America.</description>

                    <description>A new discovery by a team of paleontologists, led by Dr. Mathieu Boisville (University of Tsukuba, Japan), has uncovered a new species of the extinct genus Ontocetus from the Lower Pleistocene deposits in the North Atlantic. This species, named Ontocetus posti, displays surprising similarities in feeding adaptations to the modern walrus (Odobenus rosmarus), highlighting an intriguing case of convergent evolution. The research is published in the journal PeerJ.</description>

                    <description>A study led by Baylor University biologist Sarah Kienle, Ph.D., and published in the journal Polar Biology has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. Kienle and her team&#039;s third published study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.</description>

                    <description>While the sounds of our oceans may be familiar to us through the lens of nature documentaries, from the haunting calls of whales to the barks of some fish, this acoustic environment can provide a wealth of knowledge to scientists regarding the complex interplay of nature and humanity. Not only this, but ocean soundscapes can record environmental changes, hinting at the ever-evolving underwater world and its response to climate change.</description>
