Amy Yackel Adams, PhD
Amy Yackel Adams is a Research Ecologist focusing on improving management decisions of invasive reptiles worldwide.
Amy leads a diverse research program with other USGS scientists and various collaborators (NPS, USDA-NWRC, USFWS, DoD, universities, and state agencies) pertaining to early detection and rapid response, biology, ecology, genetics, control tool evaluation, eradication, and quantitative model development to improve adaptive management of invasive reptile species. Yackel Adams’ research areas in the Greater Everglades Ecosystem and Pacific Islands include: 1) Population and vital rate estimation of invasive Burmese Pythons, Veiled Chameleons, and Brown Treesnakes; 2) Estimating the impact of Brown Treesnakes on prey populations; 3) Enhancing early detection of invasive reptiles using new tools; and 4) Development and evaluation of removal and abundance models to inform and optimize eradication efforts.
