Small lizards.
Big questions.
Exploring how populations respond to new environments, from Mediterranean islands to neighborhoods across the United States.

CONNECTING BIOGEOGRAPHY ✳ BEHAVIOR ✳ HABITAT USE ✳ & CONSERVATION TO UNDERSTAND SPECIES INTRODUCTIONS
Our research focuses on a few central questions:
What happens to native communities when Italian wall lizards arrive?
Italian wall lizards connect questions about population history, individual behavior, and the ecological communities they join. Research combines field observations, experiments, and spatial data to understand these connections.

01 / Across landscapes
Islands & introductions

Your observation can help
Share a photograph and location to help document where wall lizards occur.
A scientist behind the stories
Meet Breann.
Breann Richey is a Ph.D. candidate in Ecology and Evolutionary Biology at Texas A&M University. Her research examines the ecological and evolutionary processes contributing to introduction, establishment, and spread, and how native communities respond.
Her work brings together international field research, student mentorship, spatial analysis, and observations from the people who know their local landscapes best.
