Welcome to The Riverscape Ecology Lab
Work in our 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. Our work strongly emphasizes how anthropogenic environmental manipulations, either destructive or restorative in nature, cause shifts in fish abundance, distribution, and community structure.

In the busiest summer in REL history the gang visited >200 sampling sites and conducted >2000 seine hauls. We seined minnows in the Great Plains (led by Erin Nguyen), tracked movement of multiple imperiled minnows (led by Zach Steffensmeier), completed tracking of Alligator Gar in the Brazos River (led by Hayden Roberts), sampled 102 locations in the Colorado River basin (led by Lindsey Elkins), and resurveyed historical sites sampled by Bill Matthews and Edie Marsh-Matthews from the 1970s and 1990s (led by Steph Parker). The slideshow below is a sampling of some of our sampling.
