To determine whale pregnancy, researchers have relied on visual cues or hormone tests of blubber collected via darts, but the results were often inconclusive. Research from the National Institute of Standards and Technology (NIST) points to a weakness of previous testing and evaluation methods and provides a new hormone testing regime that offers better results.
A new study from University of Michigan biologists presents the first genetic evidence of resistance in some bats to white-nose syndrome, a deadly fungal disease that has decimated some North American bat populations.
By watching videos of each other eating, blue tits and great tits can learn to avoid foods that taste disgusting and are potentially toxic, a new study has found.
A growing body of research shows that birds' spring migration has been getting earlier and earlier in recent decades. New research from The Auk: Ornithological Advances on Black-throated Blue Warblers, a common songbird that migrates from Canada and the eastern US to Central America and back every year, uses fifty years of bird-banding data to add another piece to the puzzle, showing that little-studied fall migration patterns have been shifting over time as well.
Otago scientists studying sperm whales off the coast of Kaik?ura have discovered earthquakes affect their ability to find food for at least a year. The University of Otago-led research is the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.
A secret to survival amid rising global temperatures could be dwelling in the tidepools of the US West Coast. Findings by University of California, Irvine biologists studying the genome of an unusual fish residing in those waters offer new possibilities for humans to obtain dietary protein as climate change imperils traditional sources. Their paper appears in Proceedings of the Royal Society B.
Analysis of Paleolithic-era teeth from a 28,500-year-old fossil site in the Czech Republic provides supporting evidence for two groups of canids -- one dog-like and the other wolf-like - with differing diets, which is consistent with the early domestication of dogs.
Researchers from the University of Oxford have discovered that the Himalayan wolf is a unique wolf characteristically adapted to the harsh life in the Asian high altitudes where low oxygen levels challenge all life forms.
First evidence that animal DNA methylation patterns can be passed to the next generation.
Researchers from the Department of Zoology at the University of Oxford have contributed to a monumental international study, published today in Nature, that has shown what factors determine how many bird species can be found on any given island.
