Work in our Riverscape Ecology Lab focuses on the conservation and sustainable management of freshwater fish diversity, understanding reasons for its decline, and developing approaches for mitigating threats in Texas, the southern Great Plains, and beyond. We address questions regarding species- and community-level change across spatial and temporal scales using a variety of study approaches, including meta-analyses, field experiments, natural snapshot and trajectory experiments, landscape modeling, and molecular techniques.
