Megan Winzeler
Megan Winzeler is a Biologist at the National Wildlife Health Center.
Megan has worked across multiple scientific and educational disciplines throughout her career. Her research focuses on the effects of natural and anthropogenic stressors on amphibians and reptiles (including contaminants, hydroperiods, and diseases). At the NWHC, she works with teams that combine field ecology with genetic tools to answer important questions about amphibian and reptile disease dynamics and conservation. Megan has a strong background in science communication, working with communities in Georgia and South Carolina to understand the information presented in state and federal environmental monitoring programs. She has given over 100 educational talks and events that reached over 15,000 individuals annually while at the University of Georgia. She has created curriculum and presentations ranging from native wildlife and habitat conservation to understanding risk associated with environmental contaminants.

Broad-scale assessment of methylmercury in adult amphibians
Mercury (Hg) is a toxic contaminant that has been mobilized and distributed worldwide and is a threat to many wildlife species. Amphibians are facing unprecedented global declines due to many threats including contaminants. While the biphasic life history of many amphibians creates a potential nexus for methylmercury (MeHg) exposure in aquatic habitats and subsequent health effects, the broad-scal
