Tyler Pilger

Fisheries Biologist

Tyler Pilger is a fisheries biologist with extensive experience in population genetics and community ecology of freshwater fishes in the Great Plains and desert Southwest, USA. He has experience with electrofishing, mark-recapture studies using PIT and VIE tags, and radio telemetry of fish. Additionally, he has a wide array of sample collection and laboratory experiences that include genetic, stable isotope, diet, geometric-morphometric, and otolith microchemical analyses. His quantitative skills include univariate and multivariate statistics, genetic analyses, simulation, programming in both R and Python languages, and Geographic Information Systems (GIS).

Tyler’s professional research focuses on landscape-scale factors associated with patterns of fish abundance, as well as genetic and demographic resilience to disturbance. He also assists in study design, statistical analysis, and technical reporting for a variety of complex research projects. Tyler holds a Ph. D. in Biology from the University of New Mexico, where he studied conservation genetics of threatened and endangered fishes and the influence of interspecific life-history differences on population genetics. He received a M.Sc. in Biology at Kansas State University studying the effects of nonnative predators on native fish trophic dynamics
