While 2018 marks the centenary of the death of the last captive Carolina parakeet -- North America's only native parrot, a team of researchers have shed new light on the previously known geographical range of the species. Their data paper, published in the open access Biodiversity Data Journal, is the most comprehensive occurrence dataset for the species ever produced.
Polar bears are under increasing risk and one of the threats was thought to be an inefficient walking style, which could drive them to starvation as they are forced to walk further to find food as the summer sea ice retreats. However, new measurements of the metabolic rates of captive polar and grizzly bears suggests that their walking style is as efficient as that of other large mammals.
A graduate student at Scripps Institution of Oceanography at the University of California San Diego and colleagues from NOAA's Office of National Marine Sanctuaries have discovered the world's first known manta ray nursery.
Past studies have shown that biparental care of offspring can be affected negatively when females and males are exposed to bisphenol A (BPA. In a study published today in the journal PLOS One, researchers at the University of Missouri found that mice pups whose grandparents had been exposed to BPA, had different vocalization patterns. This, in turn, could also affect the amount of parental care they received. Scientists believe results could have important relevance to humans.
Local conservation actions can significantly boost coral's resilience to, and recovery from, climate-induced thermal bleaching by reducing other energy-sapping stresses the coral faces, a Duke-led study finds. Scientists found they could reduce the extent of bleaching by half if they removed or reduced populations of coral-eating snails from affected reefs. The coral's recovery from bleaching was also enhanced.
A new paper in the journal Animal Behaviour examines whether smarter animals might be better at learning to live in cities -- but, at the same time, also may come into more conflict with humans.
A new study by a team of international experts, led by University of Witwatersrand Ph.D. candidate Kathleen Dollman and Professor Jonah Choiniere published today in the American Museum Novitates, endeavoured to further explore the mouth of one of the earliest occurring and least understood groups of crocodilians, the shartegosuchids.
Tracking data from two great white sharks reveals that they spend more time deep inside warm-water eddies, suggesting that's where they like to feed.
University of Queensland (UQ) and Wildlife Conservation Society (WCS) researchers argue that the world needs more diverse, ambitious and area-specific targets for retaining important natural systems to safeguard humanity.
An international team of scientists have discovered small communities of corals that are flourishing against the odds while so many around the world are dying.
