Ever since the nineteenth century scientists have recognized that some regions contain more species than others, and that the tropics are richer in biodiversity than temperate regions. But why are there more species in the tropics? A new study publishing 28 January in the Open Access journal PLOS Biology scrutinizes most of the living mammalian species and reveals a two-fold mechanism; the rate at which mammals arose was higher in the tropics, and the rate at which they became extinct lower....

National Park Service Collaborates With Outside Experts To Conserve Migratory Wildlife
2014-01-17 09:59:12

Wildlife Conservation Society A new paper details a collaboration between the National Park Service (NPS) and outside experts, including Wildlife Conservation Society (WCS) scientists, in developing recommendations to conserve aerial, marine, and terrestrial populations of migrating wildlife that move in and out of US national parks, often coming from distant regions of the globe. The paper, "Optimism and Challenge for Science-based Conservation of Migratory Species in and out of U.S....

Global Warming Behind Early Bird Migration
2013-11-13 10:00:44

Brett Smith for redOrbit.com - Your Universe Online Scientists have been seeing some bird species migrate earlier and earlier each year and now a team of UK and Icelandic researchers has shown that warming temperatures are behind the creeping back of this instinctive behavior, according to their report in Proceedings of the Royal Society B. “We have known that birds are migrating earlier and earlier each year – particularly those that migrate over shorter distances,” said report...

Sandpipers Exhibit Different Feeding Behavior Depending On Position In Group
2013-10-28 11:52:55

University of Montreal The behavior of semipalmated sandpipers (Calidris pusilla) feeding during low tide in the Bay of Fundy, New Brunswick, surprised Guy Beauchamp, an ornithologist and research officer at the University of Montreal's Faculty of Veterinary Medicine. While individuals on the periphery remained alert and used short pecks to feed on the mudflats, birds in the middle of the group relaxed their vigilance and fed on a different resource. The more peripheral group members were...

Molecular Clock Of The Common Buzzard
2013-10-23 09:27:24

University of Bielefeld Bielefeld biologists reveal the influence of genes on dispersal behavior Be it hibernation or the routes of migratory birds: all animal behavior that is subject to annual rhythms is controlled by a molecular clock. Although this has been known for a long time, in many cases it is still unclear how far genes are involved in setting this internal clock. Up to now, this also applied to the common buzzard and its migration from parental breeding grounds. Behavioral...

Lack Of Rain Halts Migration Patterns Of Christmas Island Crabs
2013-10-11 08:56:41

April Flowers for redOrbit.com - Your Universe Online The Christmas Island red crab makes a hard and amazingly-precise journey every year from its earthen burrow to the shores of the Indian Ocean for weeks of mating and egg-laying. The crabs are native to the Australian territories of Christmas Island and the Cocos (Keeling) Islands. When the November rains begin, millions of the crabs begin rolling across the island roads and landscape in crimson waves. Crabs scuttle for two weeks...

Paleoclimate simulations reveal potential 'green corridors' across North Africa Three ancient river systems, now buried, may have created viable routes for human migration across the Sahara to the Mediterranean region about 100,000 years ago, according to research published September 11 in the open access journal PLOS ONE by Tom Coulthard from the University of Hull, UK, and colleagues from other institutions. Simulating paleoclimates in the region, the researchers found quantitative...

Studying The  Importance Of Learning How To Migrate
2013-08-29 15:07:19

University of Maryland Scientists have studied bird migration for centuries, but it remains one of nature's great mysteries. How do birds find their way over long distances between breeding and wintering sites? Is their migration route encoded in their genes, or is it learned? Working with records from a long-term effort to reintroduce critically endangered whooping cranes in the Eastern U.S., a University of Maryland-led research team found evidence that these long-lived birds learn...

The Green Pygmy Goose (Nettapus pulchellus) is a small perching duck found in southern New Guinea and northern Australia. It is largely resident, apart from dispersion during the wet season. The habitat is well vegetated lowland lagoons and other permanent fresh waters.

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...
