The Office of the Vice President for Research is pleased to host the next Water@Wayne seminar on Thursday, January 10, 2019 at 2:30 p.m to 4:00 p.m. in the Bernath Auditorium located in the David Adamany Undergraduate Library. The seminar is free and open to the public; registration is requested.

The Water@Wayne Seminar Series presents "Toxicologic Tinkering with Life's Rhythms" with Gerald A. LeBlanc, Ph.D., North Carolina State University. Dr. Gerald LeBlanc is a Professor in the Department of Biological Science, North Carolina State University. Dr. LeBlanc maintains an active research program in environmental endocrine toxicology. This research involves elucidating neuro-endocrine processes that contribute to the regulation of biological processes and their disruption by environmental agents.


Many of life’s processes conform to biological rhythms. These rhythms vary in length from seconds to years and are often synchronized to environmental cues. This linkage to “natural” environmental cues renders biological rhythms potentially susceptible to disruption by “unnatural” environmental cues such as environmental chemicals. This talk will address the following questions. 1) What environmental and physiological processes regulate infradian rhythms (rhythms that are longer that 24-hour circadian rhythms)? 2) What aspects of the rhythms might render them susceptible to disruption by environmental chemicals? 3) What chemicals actually perturb these rhythms? 4) What are the consequences of such perturbations? The seminar will address these questions in the context of two infradian rhythms, the bi-annular sexual reproductive rhythm and the multi-day molting rhythm in the freshwater crustacean Daphnia sp..

A short reception will immediately follow the seminar.
