Dramatic distribution losses and a few major distribution gains are forecasted for southwestern bird and reptile species as the climate changes, according to just-published research by scientists with the U.S. Geological Survey, the University of New Mexico, and Northern Arizona University.
Just released, the latest edition of the nation’s most comprehensive look at land-surface conditions from coast to coast shows the extent of land cover types from forests to urban areas. The National Land Cover Database (NLCD 2011) is made available to the public by the U.S. Geological Survey and partners.
Warming temperatures due to climate change are exposing endangered Hawaiian forest birds to greater risk of avian malaria. But new research led by the U.S. Geological Survey holds out some hope that the birds may be able to adapt.
The recent recipient of two major awards, Craig D. Allen, a research ecologist with the U.S. Geological Survey Fort Collins Science Center, has loved trees since childhood. He is now considered an expert of world renown on the twin phenomena of forest changes and tree mortality resulting from climate warming and drought, and in 2010 was twice recognized for his scientific contributions.
Climate change has had a significant effect on mountain vegetation at low elevations in the past 60 years, according to a study done by the University of California at Davis, University of Wisconsin-Madison, and U.S. Geological Survey.
TEMPE, Ariz. — Climate change and growing human demands for water are leaving an indelible mark on rivers and streams, shortening food chains and eliminating some top predators like large-bodied fish, according to a new study led by Arizona State University and co-authored by a U.S. Geological Survey scientist.
WASHINGTON — Dust caused by human activities in the American desert Southwest is a contributing factor in speeding up the melting of snow and reducing runoff in the mountains of the Colorado River basin, according to a new study led by NASA and co-authored by the U.S. Geological Survey.
LEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.
TACOMA, Wash. — Washington’s only “benchmark” glacier continues to lose mass as a result of changes in climate, according to a report by the U.S. Geological Survey.
