Ashley Long

As a research scientist for the Texas A&M Institute of Renewable Natural Resources, Dr. Ashley Long examines factors that drive species’ distributions and wildlife population dynamics. Her current research collaborations in Texas and California include investigations of avian movements, survival, and reproductive success in relation to vegetation management (e.g., prescribed burning, thinning), development (e.g., road construction), and natural landscape alterations (e.g., wildfire). In addition to bird research, she has contributed to studies on bats, bobcats, snakes, and ectoparasites and is most interested in how spatial and temporal variation in environmental conditions and human-induced habitat change influence interactions among organisms.

Prior to joining the Institute, Dr. Long was a graduate research assistant at Texas A&M University under Dr. Michael L. Morrison and conducted her dissertation research on the influence of vegetation structure and composition on golden-cheeked warbler abundance and productivity. She received her master of science in biological sciences from Emporia State University where she studied the effects of prescribed burning on birds nesting in shrub-encroached, shortgrass prairie under Dr. William E. Jensen, and she received her bachelor of science in biology at Northland College.
