Now researchers at The Institute for Genomic Research and colleagues report that the sharpshooter's deprivation diet is sneakily supplemented by two co-dependent bacteria living inside it.
Some electric fish in Africa have different communication patterns and won't mate with each other, although their DNA is the same, find Cornell scientists. They think the fish are living examples of a species of fish diverging into separate species.

Polar bears from East Greenland contain the highest recorded concentrations of organohalogen contaminants (OHCs)--more than any mammalian species in the world.

The study is published in the latest Environmental Toxicology and Chemistry.
A new monkey species discovered last year by scientists with the New York-based Wildlife Conservation Society (WCS) and other groups is now shown to be so unique, it requires a new genus "“ the first one for monkeys in 83 years.
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.

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.

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.

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).
A study of zoo lions across U.S. by Dr. Bruce Patterson of The Field Museum shows that cold temperatures result in longer, thicker manes. Differences in manes are not a result of natural selection, but a flexible trait matching local weather conditions.
The Bronx Zoo-based Wildlife Conservation Society (WCS) today applauded a decision today by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as "chiru," as an endangered species.
If you think you've got a bad boss, one who loves to chew people out, or if you work with backstabbing co-workers, be thankful you are not a wasp. If you were, chances are your nestmates might bite you to communicate that it is time for you to leave the nest and forage for the colony.
