Susan E. Riechert

Susan Elise Riechert (born October 20, 1945) is an American behavioral ecologist known for her research in evolutionary biology, evolutionary game theory and the behavior of spiders. She is also known for her "biology in a box" teaching materials, used by hundreds of thousands of elementary and secondary school students in Tennessee.

Until her retirement in 2020, Riechert worked at the University of Tennessee as UTK Distinguished Service Professor and as UTK Chancellors Professor of Ecology & Evolutionary Biology. She was president of the American Arachnological Society for 1983–1985, and president of the Animal Behavior Society in 1997.

Early life and education Riechert lost much of her hearing through scarlet fever as a child. After nearly drowning trying to catch fish for the class, she switched to a subject that was safer to catch, spiders.

Of particular note is the fact that several of her studies were focused on the effect that variations in a species had on the behavior of its members. In 1988, she and Peter Hammerstein conducted a study that led her to hypothesize that riparian populations of Agelenopsis aperta could not fully adapt to their new environs because of gene flow from non-riparian populations of the species that lived nearby. In 1989, Riechert co-authored a paper titled "Genetically-based variation between two spider populations in foraging behavior," in which she and fellow arachnologist Ann Hendrick discussed how genetic differences in the population of one species can have an impact on the way they search for food.

Members of the genus Agelenopsis (American grass spiders) featured prominently in Riechert's work, particularly the species Agelenopsis Aperta. Riechert demonstrated that the aforementioned spiders engaged in territorial disputes similar to those seen in much larger creatures. In 2008, Riechert was named a Fellow of the American Association for the Advancement of Science, "for distinguished contributions to the field of behavior and ecology". She won the Southeastern Conference Faculty Achievement Award for 2016. The Animal Behavior Society gave Riechert their 2018 Penny Bernstein Distinguished Teaching Award. A festschrift symposium, sponsored by the Animal Behavior Society, was held in her honor in 2020.

Notable associates Jonathan Pruitt achieved a PhD with Riechert as his advisor and was able to attain prestigious positions in academia despite his youth thanks to his acclaimed publications. However, the validity and truthfulness of his research data was called into question in 2020. Since then, many of the papers Pruitt co-authored based on his data have been retracted, others called into question, and papers from other authors which cited Pruitt's compromised papers have had to have been corrected and updated. In November 2021, University of Tennessee Knoxville removed Pruitt's dissertation from its library. Riechert said she was "devastated" by the news, but added that if Pruitt had truly falsified data, he had to "pay the price".
