Amphibians, United States

During a 3-year postdoc with the U.S. Geological Survey (program: Amphibian Research and Monitoring Initiative), I participated in several studies that investigated the trends and stressors of amphibian populations in the United States. I led the analyses of most of these studies.

The results of these studies are published in several scientific papers:

Responses of amphibian populations to climate change. 
(I led the analyses of this study)

Effect of cattle exclosures on Columbia Spotted Frog abundance. 
(I co-led the analyses of this study)

Effects of multiple drivers on continental-scale amphibian declines. 
(I was a minor contributor on this one)

I also worked on the development of various statistical methods to deal with false positive detections and species misidentification errors in amphibian occupancy studies.

This work led to the publications of several scientific papers:

Two-species occupancy modeling accounting for species misidentification and nondetection.

A new framework for analyzing automated acoustic species-detection data.

Modeling false positive detections in species occurrence data under different study designs.

Project’s Status: Completed. Results are published in peer-reviewed scientific journals (see links above).
