New Model Accurately Describes Migratory Animals’ Extinction Risk
2011-11-17 04:14:41

Predicting the risk of extinction is a complicated task, especially for species that migrate between breeding and wintering sites. Researchers at the University of Georgia and Tulane University have developed a mathematical model that may make such predictions more accurate. Their work appears in the early online edition of the Royal Society journal Biology Letters. "The concern is that for a lot of species, we don't know very much about their wintering grounds," said Richard Hall,...

US Forests Are Not Keeping Pace With Climate Change

More than half of eastern U.S. tree species examined in a massive new Duke University-led study aren't adapting to climate change as quickly or consistently as predicted. "Many models have suggested that trees will migrate rapidly to higher latitudes and elevations in response to warming temperatures, but evidence for a consistent, climate-driven northward migration is essentially absent in this large analysis," says James S. Clark, H.L. Blomquist Professor of Environment at Duke's...

Mimecastâs new Exchange migration guidelines now provide explanations on how to prepare the existing infrastructure, what safeguards to put in place and how to perform the Exchange migration. The company has just introduced six-month package of Migration Services aimed at organisations upgrading to Microsoft Exchange 2010 or Office 365, helping to prevent email downtime and data loss during the migration process. (PRWEB) October 11, 2011 An Exchange migration can produce a...

In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia. The research, published in the American Journal of Physical Anthropology, is part of a special section which explores who the first Americans were and how they were able to settle in the last great unexplored habitat. The research, by Sohini...

Researchers at Brown University and Stanford University have pieced together ancient human migration in North and South America. Writing in the American Journal of Physical Anthropology, the authors find that technology spread more slowly in the Americas than in Eurasia. Population groups in the Americas have less frequent exchanges than groups that fanned out over  Europe and Asia. How modern-day humans dispersed on the planet and the pace of civilization-changing technologies that...

HARRISBURG, Pa., July 26, 2011 /PRNewswire-USNewswire/ -- Early Canada goose and dove hunters will be able to take to the fields of Penn's Woods on Sept. 1, as part of Pennsylvania's 2011-12 migratory bird seasons announced today by Pennsylvania Game Commission Executive Director Carl G. Roe. Dove hunters will have the opportunity to participate in a triple-split season, which will see some shifts due to the way the calendar falls this year. During the first season (Sept. 1 - Oct. 1),...

Until recently, migration patterns, such as those adopted by birds all across the Amazonian rainforest, have not been thought to play an important role in the spreading of beneficial genes through a population. Researchers have now, for the first time, been able to predict the chance of a gene spreading when given any migration pattern, potentially providing an insight into the migration patterns of animals throughout history. Even more impressively, the concepts from these predictions can be...

In the final article in a six-part PLoS Medicine series on migration & health, Anita Davies and colleagues from the International Organization for Migration (IOM) discuss the specific health risks and policy needs associated with return migration. As global migration increases generally, so too does return to home countries, where the health of returnees is impacted by the cumulative exposure to social determinants and risk factors of health during the migration process, during the return...

The Canada goose (Branta canadensis), also called the Canadian Goose in North America, belongs to the Branta genus of geese. This genus contains species with largely black plumage, distinguishing them from the grey Anser species. The species name, canadensis, is a New Latin word meaning "of Canada". The black head and neck with white "chinstrap" distinguish this goose from all except the Barnacle goose, but the latter has a black breast and grey, rather than brownish, body plumage. There...

The Red Knot (Calidris canutus), or Knot in Europe, is a species of bird found in the tundra and Arctic mountains in the far north of Canada, Europe and Russia. North American birds migrate to coastal Europe and South America, while European birds migrate to Africa, Papua New Guinea, Australia and New Zealand. This species has an extensive range and a large population of about 1.1 million individuals. There are six subspecies. The adult is 9 to 10.25 inches in length with an 18.5 to 20.8...
