Researchers at the University of Montana recently discovered that hybridization played an important role in snowshoe hares' ability to match their environment.

A team of scientists and students, conducting research aboard the R/V Akademik Ioffe, will offer select museums, as well as classrooms and citizen scientists worldwide, an opportunity to explore with them in real time a dramatically changing Arctic Ocean, and to discuss their research in the first-ever live, interactive broadcasts from the fabled Northwest Passage.

In a new study in Science Advances, researchers describe a way to quickly sift through thousands of hours of field recordings to estimate when songbirds arrive at their Arctic breeding grounds. Their research could be applied to any dataset of animal vocalizations to understand how migratory animals are responding to climate change.

A new study by Los Alamos National Laboratory scientists and colleagues confirms that increasing minimum winter temperatures allow beetles to expand their range but reveals that overcrowding can put the brakes on population growth.

University of Kansas researchers discovered friction -- or 'basal drag' -- between ice sheets and the hard bed underneath has no influence on how fast glaciers flow.

Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future.

An international team describes the climate change-induced responses of the tropical atmospheric circulation and their impacts on the hydrological cycle. It also depicts the theoretically predicted changes and diagnose physical mechanisms for observational and model-projected trends in large-scale and regional climate.
