A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.
A total of 174 chicken breeds are described in a publicly accessible database which scientists from the University of Göttingen and the Friedrich Loeffler Institute in Neustadt-Mariensee have built up in recent years with numerous international partners. This database, the Synbreed Chicken Diversity Panel (SCDP), includes information about a large proportion of the available chicken species and their diversity.
GAINESVILLE, Fla. --- Feet from the raw bars and sherbet-colored condominiums of Florida's Cedar Key, researchers discovered a new species of egg-sucking sea slug, a rare outlier in a group famous for being ultra-vegetarians.
Sea otters have low genetic diversity, which could endanger their health as a species, a UCLA-led team of life scientists has discovered. The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction.
Dogs have evolved new muscles around the eyes to better communicate with humans. New research comparing the anatomy and behavior of dogs and wolves suggests dogs' facial anatomy has changed over thousands of years specifically to allow them to better communicate with humans.
BATON ROUGE, LOUISIANA, June 17, 2019--Getting an excellent rabbiteye blueberry harvest requires helpful pollinators--particularly native southeastern blueberry bees--although growers can bring in managed honey bees to do the job, according to Agricultural Research Service (ARS) scientists.
A recent study published in the peer-reviewed journal PeerJ - the Journal of Life and Environmental Sciences highlights the fact that the economic benefits of commodity export for primate habitat countries has been limited relative to the extreme environmental costs of pollution, habitat degradation, loss of biodiversity, continued food insecurity and the threat of emerging diseases.
Climate and ecosystems are changing, but predation on shorebird nests has changed little across the globe over the past 60 years, finds an international team of 60 researchers. The study published in Scienceon 14 June 2019 challenges a recent claim that shorebird eggs are more often eaten by predators due to climate change, and more so in the Arctic compared to the tropics. The research shows that these claims are a methodological artefact.
Many of an organism's traits are influenced by cues from the organism's environment. These features are known as phenotypically plastic traits and are important in allowing an organism to cope with unpredictable environments.
DURHAM, N.C. -- Duke University scientists have given us another way to tell which endangered lemur species are most at risk from deforestation -- based on the trillions of bacteria that inhabit their guts.
Fossils of a giant new species from the long-extinct group of sea creatures called trilobites have been found on Kangaroo Island, South Australia.
Giant petrels will be "temporary" winners from the effects of climate change in the Antarctic region - but males and females will benefit in very different ways, a new study shows.
When a male or female white-browed sparrow-weaver begins its song, its partner joins in at a certain time. They duet with each other by singing in turn and precisely in tune. A team led by researchers from the Max Planck Institute for Ornithology in Seewiesen used mobile transmitters to simultaneously record neural and acoustic signals from pairs of birds singing duets in their natural habitat.
New research published in the Journal of Natural History indicates that zebras' stripes are used to control body temperature after all - and reveals for the first time a new mechanism for how this may be achieved.
When it comes to making friends, it appears dolphins are just like us and form close friendships with other dolphins that have a common interest. The findings, published in the Proceedings of the Royal Society B by an international team of researchers from the Universities of Bristol, Zurich and Western Australia, provides further insight into the social habits of these remarkable animals.
