Fish conservation

Anticipating future threats to fish in dryland streams requires a predictive, proactive scientific approach that aims to identify and priority critical conservation areas and endemic species at risk. Our research explores how native fishes in Arizona respond to the multi-scale effects of dams, climate and invasive species with the goal of advancing the science and conservation of this highly imperiled and under-studied fauna.

Landscape genetics

Amphibians face a particularly tenuous existence in desert environments, with suitable habitat patches often fragmented or ephemeral during periods of prolonged droughts; thus even small differences in climate and water management are expected to have significant impacts on the persistence of these organisms in dryland streams. Our lab is using desert amphibians as a model system and applying landscape genetics as a tool to explore the linkages between climate, hydrologic connectivity, and population loss, range shifts, and phenological change.
