Eastern tiger salamanders are on the move! This one was spotted crossing the road at St. Croix Wetland Management District in Wisconsin. Tiger salamanders mostly eat small insects and worms.

Scientists sample a rough-skinned newt for the fungal pathogen Batrachochytrium salamandrivorans, or Bsal, at a pond near Portland, Oregon. Bsal is decimating wild salamander populations in Europe and could emerge in the U.S. thro

USGS and other scientists have studied in-depth alligator populations in Florida and Louisiana, but basic ecological knowledge is lacking for populations at the northern edge of their range.

South Carolina alligators occupy a patchwork of diverse habitats, including rivers, lakes, wooded swamps, tidal marshes, and impounded freshwater wetlands. As a mobile, opportunistic predator, alligators seasonally adjust their habitat use for feeding.

Reports of golden eagle mortality linked to wind energy facilities are cause for concern especially when coupled with the knowledge that golden eagles move great distances between breeding and wintering areas. Mortalities at a particular wind energy facility can consequently affect breeding populations of golden eagles at local and continent-wide scales.

This auger is used to collect 1 meter deep soil cores for a carbon budget study associated with the SageSTEP project. SageSTEP is a long-term, multi-disciplinary experiment evaluating sagebrush restoration methods in the Great Basin.
