In the migratory marathon, parasitized monarchs drop out early

... from Canada to Central Mexico ?one of the longest migrations of any insect species. Emory University researchers found that monarchs infected with a protozoan parasite fly slower, tire out faster and expend more energy flying than healthy monarchs. These results, published in the March issue of Ecology Letter...

Butterfly migration could be largest known

...ld be just the advance guard of one of the largest migrations of the species on record, said Arthur Shapiro, a professor and expert on butterflies at UC Davis. "This may be the biggest migration of modern times," Shapiro said. Shapiro said he is getting reports of "billions" of butterflies around Trona, near ...

New understanding of cell movement may yield ways to brake cancer's spread

...isease through the body. Scientists studying these migrations didn't know how cells determined where to go. Until now. A Burnham Institute study has identified a fragment of a protein that senses chemicals that induce a cell to move into the right direction. Guided by this fragment, the molecular machinery nee...

Displaced songbirds navigate in the high Arctic

...rds that breed in northern Canada and perform long migrations covering a few thousand kilometers to winter in the southern United States. In the study, young and adult white-crowned sparrows were captured with mistnets near Inuvik, NW Territories, Canada, during mid-July to mid-August--the end of the breeding p...

Multiple genes permit closely related fish species to mix and match their color vision

...t Lakes are renowned for their diversity: Owing to migrations of ancestor species out of Lake Tanganyika and into other lakes, such as Lake Malawi, it has been estimated that hundreds of new cichlid species have arisen in these lakes in the last 100,000 years. Thanks to the relatively recent colonization by the...

Horseshoe crab decline threatens shorebird species

... Argentina to the Artic Circle ?one of the longest migrations of any bird. And each year from April to June, the red knot stops over in the Delaware Bay to feed on horseshoe crab eggs resulting from the largest spawning of horseshoe crabs found on the East Coast of the United States. Researchers from Virginia...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...oceanographers, yielding new information about the migrations and behavior of the animals and about the environments in which they live. "We're using these animals as ocean sensors to tell us about oceanographic conditions, and we're also learning how they use the ocean--where they go and what they do," said D...

Parachuting allows krill to eat and run

...e researchers found that krill are capable of many migrations each night. What is more, the downward migration may be particularly rapid as the krill fan out their swimming legs and enter a controlled descent, akin to parachuting. The behavior is most apparent when their stomachs are full and may be an effectiv...

Creating a window on 'oceans in motion'

Academics, scientists and technical experts at the meeting aim to throw open a large, vivid new global window on...

Agriculture and tropical conservation: rethinking old ideas

...s that are left, and will it support the necessary migrations from patch to patch as local extinctions occur, which they inevitably do?" If forest patches are separated by barren pastures or fields of single crops, such as soybeans, then monkeys, birds, and other forest animals probably won't travel through t...

History-hunting geneticists can still follow familiar trail

But University of Florida researchers writing this month in an online edition of Science validate the approach, which involves tracking ...

NASA snow data helps maintain nation's largest, oldest bison herd

...el through time. "Bison have one of the longest migrations of any large mammal in the country. The fact that they are moving to low-elevation winter ranges outside the park is actually a sign of how successful our restoration efforts have been," said Rick Wallen, leader of the Park's Bison Ecology and Manage...

DNA analysis reveals rapid population shift among Pleistocene cave bears

The new work, reported by a collaborative group of researchers including Michael Hofreiter of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, appears in the February 20th issue of the journal ...

From the deep -- Researchers find new species of sea anemone

...inted out that there are now far fewer major whale migrations along the California coast. While the flesh of a dead whale decomposes within weeks, the bones can last anywhere from 60 to 100 years. "As that happens, the bacteria that break down the bones release sulfur," Daly said. "A whole community of aq...
