Current Lab Members
Dr. Rickey Cothran
I'm an ecologist that studies aquatic ecosystems. My students and I work in a variety of freshwater systems from small springs to large reservoirs and natural lakes. We ask questions in the areas of behavioral ecology, community ecology and evolutionary ecology.

Lab Alumni
Arissa Mercer
Arissa studied resource competition among cryptic species of amphipods. She is now pursing a Ph.D. in microbiology at Tulane.
Denton Parsells
Denton studied how cultural eutrophication affects sexual selection in amphipod populations. Denton is in medical school at the University of Arkansas, Fort Smith.
Casady Sublett
Casady surveyed streams in SE OK for the elusive three-tooth longhorn caddisfly (Triaenodes tridontus). She is now applying to vet school.
Rachel Uhlig
Rachel explored how mate choice affects offspring sex ratios in amphipods. She is now a graduate student at Oklahoma State University in Shawn Wilder's lab.
Joseph Alcuitas
Joseph is studied how mate quality affects offspring sex ratios in amphipods. He is working on a medical lab science degree.
Shanna Simmons
Shanna explored how female diet affects the outcome of sexual conflict over precopulatory mate guarding. She is a graduate of the PharmD program at SWOSU.
Dr. Ashna Dhoonmoon
Ashna's research centered on understanding how population parameters affect the costs associated with sexual conflict in amphipods. Ashna earned a PhD at Penn State Hershey and is currently a postdoc at Penn State College of Medicine.
Sinthia Youmbi
Sinthia addressed how predator cues affect the mating behaivor of amphipods. Sinthia is pursuing medical school.

David studied animal personality in amphipods.
Allison Statton
Allison studied the foraging preferences of aquatic hemipterans. She is now an adjunct chemistry instructor at Mid-American Christian College.
Lindsey Hendricks
Lindsey explored how very low concentrations of pesticides, that are typically found in nature, affect the growth, survival and development of amphipods. Lindsey is a CNA in western OK.
Shayla Miller
Shayla studied how female diet affects the resolution of sexual conflict in amphipods. She is currently attending OSU College of Osteopathic Medicine.
