Earthwatch teams working on St. Croix, Virgin Islands report this year's first leatherback hatchlings emerging from protected nests at Sandy Point National Wildlife Reserve. Scientists have documented a ten-fold rise in leatherbacks nesting here, and a twenty-fold increase in hatchlings produced, in response to 25 years of monitoring and conservation efforts.
When it comes to fire ants, most people prefer to wipe the venomous little varmints off the face of the Earth "“ or at least out of their own back yards. The reviled South American native that invaded the U.S. Sun Belt via 1940s Mobile, Ala., is known in biology circles as Solenopsis invicta and everywhere else as a painful pest in the grass, so to speak. Then there's Walter R. Tschinkel.
A new University of Maryland study finds that echolocating bats use a strategy to track and catch erratically moving insects that is much like the system used by some guided missiles to intercept evasive targets and different from the way humans and some animals track moving objects.
If otherwise healthy humans temporarily lost their skeletons, they could neither protect themselves nor move around. Millions of small animals, however, do lose their skeletons one or more times a year in a risky process known as molting. As arthropods grow, they must shed their tough outer shells, or exoskeletons, to have room to expand.
Dave Christianson and Scott Creel are researching elk in the northwest part of the Yellowstone Ecosystem to see how they're affected by wolves.
Collaring elk and wolves has become a welcome social event for MSU researchers who live isolated lives from mid-December through April.
New University of Washington research shows that a regulatory gene named broad, known to be necessary for development of insects that undergo complete metamorphosis, also is key for the maturation of insects that have incomplete metamorphosis.
Certain species of coral have surprised researchers by showing an unexpectedly successful approach towards survival when seriously bleached. Their innovative strategy is gluttony. The discovery, derived from experiments on coral reefs in Hawaii, provides new insights into how these tiny animals face a multitude of environmental threats.
The European starling "“ long known as a virtuoso songbird and as an expert mimic too "“ may also soon gain a reputation as something of a "grammar-marm." This three-ounce bird, new research shows, can learn syntactic patterns formerly thought to be the exclusive province of humans.
Linguists have argued that certain patterns of language organization are the exclusive province of humans. These syntactical capacities have been used to define the boundaries between humans and other creatures. Now researchers have discovered the capacity to recognize such patterns in starlings.
The Painted Bunting Observer Team (PBOT) at the University of North Carolina Wilmington is seeking help from volunteer citizens to support a research study in North and South Carolina to develop strategies to sustain and increase the numbers of these brightly colored migratory birds whose numbers are dwindling.
Three previously undescribed species of mites were discovered high in the tree canopy in the Adirondack Park, along with a species of lichen that has not been seen in New York state in some 40 years. The discoveries by a graduate student at the SUNY College of Environmental Science and Forestry raise questions about what other secrets the forest holds.
Frogs and lots of them are being discovered in the Southeast Asia nation of Lao PDR, according to the Bronx Zoo-based Wildlife Conservation Society, which says that six new frog species have been found by scientists over a two-year period.
When 10,000 honeybees fly the coop to hunt for a new home, they have a unique method of deciding which site is right. And their technique, says Cornell biologist Thomas Seeley, includes coalition building until a quorum develops.
A team of scientists from the Howard Hughes Medical Institute (HHMI) at the University of Wisconsin-Madison, reveal the discovery of the molecular mechanisms that allow animals to switch genes on or off to gain or lose anatomical characteristics.
Use of insecticides in agriculture is believed to be a major factor in regional declines in bird populations. A new study provides analyses that make objective assessments of the risk to birds at the local level anywhere in the world. The study is published in the latest Environmental Toxicology and Chemistry.
Just as baby mammals depend on their mothers' milk, the young of the African amphibian Boulengerula taitanus nourish themselves by stripping off and eating the fat-rich outer layer of their mothers' skin, according to an international team of researchers that includes University of Michigan biologist Ronald Nussbaum.
The most cost-effective way to stop non-native rats and mongoose from decimating highly endangered species on larger tropical islands is not by intensive trapping, but instead by preserving the forest blocks where wildlife live, according to a new study.
Scientists have reported an unprecedented number of unaccompanied and possibly abandoned walrus calves in the Arctic Ocean, where melting sea ice may be forcing mothers to abandon their pups as the mothers follow the rapidly retreating ice edge north.
The living fossil that still patrols the rivers of the Pacific Coast recently received a boost from the US government, but the new 'threatened' listing for the green sturgeon only applies to the southern population, and may fail to protect these fish leaving California's Sacramento River System unless stiff measures are applied over a wide geographical range, said the Wildlife Conservation Society (WCS).
