Dr. Karin Limburg, an ecologist at the State University of New York (SUNY) Colleg of Environmental Science and Forestry, will present the 2020 Pasakarnis-Buchanan Scientific Lecture, titled "Through the Heads of Fishes: Revelations in Fish Ecology Through Otolith Chemistry."
She will discuss otoliths, the small calcified organs in the hearing and balance systems of fishes. Their very structure and the chemistry they entrain represent some of the most detailed "natural logbooks" of any vertebrate group known to date. Both otolith structure and to some extent otolith chemistry provide natural calendar-clocks which date the timing of life-history events. Her talk is based on case studies of complex migration of diadromous fishes and the exposure to and impacts of aquatic hypoxia on marine and Great Lakes fishes.
Dr. Limburg will also present a public lecture on April 7 at 7 p.m. Details are available online.
