Migrating birds can and do keep their travel dates flexible, a new study published online on January 28th in Current Biology, a Cell Press publication, reveals. But in the case of pied flycatchers, at least, an earlier takeoff hasn’t necessarily translated into an earlier arrival at their destination. It appears the problem is travel […]
ANCHORAGE, ALASKA, January 2010 — A long-term study showing the changes in habitat associations of polar bears in response to sea ice conditions in the southern Beaufort Sea has implications for polar bear management in Alaska. Karyn Rode, a polar bear biologist with the U.S. Fish and Wildlife Service in Anchorage, Alaska and one […]
By Steve Gorman, Wed Dec 23, 2009 8:14pm EST LOS ANGELES (Reuters) – Earth’s various ecosystems, with all their plants and animals, will need to shift about a quarter-mile per year on average to keep pace with global climate change, scientists said in a study released on Wednesday. How well particular species can survive […]
ScienceDaily (Dec. 21, 2009) — All insect-eating migratory birds who winter in Africa and breed in the Dutch woods have decreased in numbers since 1984. This has been revealed by research conducted by the University of Groningen, the SOVON Dutch Centre for Field Ornithology, Statistics Netherlands (CBS), Radboud University Nijmegen and Alterra, published on 16 […]
Rising temperatures and sea levels brought on by climate change could have devastating effects on British wildlife from salmon to wildfowl, the Environment Agency warned. The agency said the country’s waterways could be hit by invading species, such as African clawed toads and South American water primrose, which spread disease to native wildlife and clog […]
Complex responses to Arctic climate change that may have broader community and ecosystem consequences. A developing trophic mismatch between the timing of caribou calving (blue), which has not changed, and the timing of plant growth (red), which is advancing with warming in Greenland [updated from E. Post, M. C. Forchhammer, Philos. Trans. R. Soc. B […]
By Mark Kinver, Science and environment reporter, BBC News Milder winters in the Arctic region have led to fewer Pacific brants, a species of sea goose, migrating southwards, say researchers. A study by the US Geological Survey (USGS) found that as many as 30% of the birds were overwintering in Alaska rather than migrating to […]
