Declines, Pesticides, & Abnormalities


Monday, December 16, 2013, 2 - 3:30pm Eastern

A joint webinar briefing by USGS and USFWS

Michael J. Adams, USGS Forest and Rangeland Ecosystem Science Center

Kelly Smalling, USGS New Jersey Water Science Center

Mari Reeves, USFWS Anchorage Fish and Wildlife Field Office


·         Part I: Monitoring Amphibians to Inform Decisions: New Findings from a New Approach

Mike Adams will talk about a recent paper that provides the first estimate of how fast amphibians are declining in the US. This paper was produced by the USGS Amphibian Research and Monitoring Initiative (ARMI), which works with federal agencies to address amphibian information needs. ARMI has a uniquely flexible but rigorous approach to a national monitoring program. The paper suggests that the problem with amphibian declines is worse than we thought.

·         Part II: Fungicides and Frogs: Occurrence, Accumulation, and the Implications of Being Downwind

Kelly Smalling will discuss a recent paper that documents the first occurrence of several fungicides in frogs collected from remote, high elevation national parks and forests in California. The study was a collaborative effort between ARMI and the USGS Toxic Substances Hydrology Program. The paper suggests that pesticides are moving from California's highly agricultural Central Valley to remote locations and are accumulating in frogs. Documenting the occurrence of fungicides is only the beginning and we hope this study will lead to future efforts to understand the effects of these pesticides on frogs.

·         Part III: The Landscape of Amphibian Abnormalities on US Wildlife Refuges: What We Know and Why We Care

The USFWS just completed a ten-year study of abnormal amphibians in National Wildlife Refuges across the United States – the largest scale survey of this phenomenon to date. Mari Reeves will describe the nationwide spatial and temporal patterns in this dataset.
