Scientists have discovered the world’s first known naturally fluorescent amphibian — the South American polka-dot tree frog.

Wild ducks and shorebirds do not appear to carry Newcastle disease viruses that sicken or kill poultry, according to a new study led by the U.S. Geological Survey.

A new report by the USGS finds that although snow geese are increasing rapidly in northern Alaska, they are not having a negative effect on black brant. Brant are a goose species that shares its nesting habitat with snow geese.

It has long been suspected that spiders are one of the most important groups of predators of insects. Zoologists at the University of Basel and Lund University in Sweden have now shown just how true this is – spiders kill astronomical numbers of insects on a global scale. The scientific journal The Science of Nature has published the results.

A new study from a Coastal Waters Consortium team of researchers led by Rutgers University postdoctoral researcher, Michael McCann, has found which birds, fish, insects and other animals affected by the Deepwater Horizon explosion should be given top priority for conservation, protection and research.

The giant panda’s graphic pattern has stumped biologists for years … now they have an answer.

Despite recent changes to the growing season for plants in the Arctic, Alaska, caribou appear to have remained in sync with these changes over the last 30 years. 

The speed at which a tiny ant evolves to cope to its warming city environment suggests that some species may evolve quickly enough to survive, or even thrive, in the warmer temperatures found within cities, according to a new study by researchers at Case Western Reserve University.

Projected increases in the frequency, intensity and duration of heatwaves in the desert of the southwestern United States are putting songbirds at greater risk for death by dehydration and mass die-offs, according to a new study.

Scientists can now predict which avian species are most sensitive to the increasingly dominant shrub habitat spreading across Alaska, a capability that will be useful for natural resource agencies in Alaska charged with managing these resources.
