Cheryl Brehme

Biography

Cheryl has been a biologist with the USGS, Western Ecological Research Center since 2003. She specializes in long-term monitoring programs, conservation ecology and road ecology.  She uses current ecological concepts and principles to design, implement, improve, and interpret complex research and monitoring projects for reptiles, amphibians and mammals. In addition to conducting fieldwork for her projects, she uses occupancy and mark-recapture models to analyze dynamic spatial and demographic processes as well as multivariate models for community dynamics in response to habitat change.
