The number of Adélie penguins living in East Antarctica may be double what scientists previously thought. New data collected by researchers at the University of Adelaide in Australia estimates the population number at nearly six million—almost four million higher than previous estimates.
Stress is a factor not only in the best human families; it also appears among animals. To see how bird family members interact with each other in stressful situations, researchers from Vetmeduni Vienna and the University of Gdansk, Poland, studied parent-offspring interactions in a long-lived seabird, the little auk (Alle alle).
While global pollution is a serious issue for most of the researchers in the field, a team of scientists have discovered that the levels of mercury in seabirds off the coast of British Columbia did not change over the past half a century. The new research suggests that, in fact, the mercury in seabirds is a little lower. Although in normal conditions this would be great news, a drop in the number of fish stocks close to the surface has caused the birds to make a change in their dietary habits, which resulted in eating from areas that are lower in bacteria. This occurrence is all the more negative, as bacteria have a role in controlling the levels of mercury in their bodies.
Publishing in Nature Communications and featured by the American Association for the Advancement of Science, Associate Professor of Atmospheric Science Jeff Pierce and graduate student Jack Kodros present evidence linking ammonia emissions from summertime Arctic seabird-colony excrement, called guano, to newly formed atmospheric aerosol particles. These particles can in turn influence Arctic cloud properties and their effects on climate.
As the oceans fill with plastic debris, hundreds of marine species eat astonishing amounts of it. Yet the question of why so many species, from the tiniest zooplankton to whales, mistake so much of it for food has never been fully explored. Now a new study explains why: It smells like food.
New research shows that frigatebirds can sleep on the wing, with just one or both halves of their brain
Shifts in the distribution of Spectacled Eiders, a predatory bird at the top of the Bering Sea’s benthic food web, indicate possible changes in the Arctic’s marine ecosystem, according to new research.
New Monash University research has paved the way for drones to revolutionise ecological monitoring.
Are die-offs occurring more often?
(From the New York Times/by James Gorman) — To the casual reader, it can certainly seem that reports emerge on a regular basis of thousands of animals of a species suddenly …
A local scientist and entrepreneur is leadinga mapping project to find out where potential oil spills could have the worst effects on seabirds.
Bird watchers know where sea ducks like the surf scoter breed — across Canada and Alaska — and where they spend their winters — along the U.S. coasts, in bodies of water like the Chesapeake and Delaware bays.
In the storm debris littering a Washington State shoreline, Bonnie Wood saw something grisly: the mangled bodies of dozens of scraggly young seabirds.
