armi.usgs.gov — The U.S. Geological Survey's Amphibian Research and Monitoring Initiative (ARMI) is a multidisciplinary effort to determine the status and trends of amphibians in the U.S., research the causes for amphibian declines, and provide scientific information to decision-makers to help halt or reverse declines. This website includes information on ARMI's More...

www.npwrc.usgs.gov — Interest in amphibians continues to rise as people become more aware of this fascinating group of animals. To the uninitiated all frogs may look alike; ditto for salamanders (in the same manner that beginning birders are overwhelmed by the immense variety of small brown birds). One of the purposes of this checklist and online identification guide More...

www.fort.usgs.gov — This report provides a preliminary review of adaptation options for climate-sensitive ecosystems and resources in the United States. The term "adaptation" in this document refers to adjustments in human social systems (e.g., management) in response to climate stimuli and their effects. Since management always occurs in the context of desired More...

armi.usgs.gov — At least 13 amphibian species are found on the Colorado Plateau, although some have very limited distributions in this bioregion. Amphibian declines have been documented in many parts of the world, but knowledge of amphibians on the Colorado Plateau is inadequate to determine population status or trends for most species. The U.S. Geological More...

www.fort.usgs.gov — This publication is a technical conservation assessment of the wood frog (Rana sylvatica). Using cross-validation techniques, scientists evaluated the ability of several published and new predictive equations to estimate lean and lipid mass of Semipalmated Sandpipers (Calidris pusilla) and White-rumped Sandpipers (C. fuscicollis).
