Researcher to speak at FLI

Tim Sellers, an assistant professor of biology and environmental science at Keuka College and director of its Center for Aquatic Research, will speak on “Microscopic, But Macro-important: The Phytoplankton of Keuka Lake,” beginning at 6:30 p.m. Wednesday, Jan. 24 at the Finger Lakes Institute Classroom, 601 S. Main St.

Phytoplankton, which are floating microscopic algae in lakes, are central to water quality issues and the lake’s ecological health. “The Center for Aquatic Research is doing a series of experiments to determine what factors affect phytoplankton growth and type,” said Sellers, an expert on nutrient limitation studies.

These plants can respond rapidly to changes in the watershed including nutrient runoff, and form the base of energy and nutrition sources for the majority of aquatic organisms in the lake’s food web. Researchers are working on ways to better understand the mechanisms that influence the phytoplankton and the resulting food web, as part of the effort to improve water quality.

Sellers’ talk will cover how students and faculty researchers are integrating their phytoplankton-based research studies with the existing field work conducted by many regional groups. The Center for Aquatic Research is partnering with the Finger Lakes Institute in studying the quality of the water in the region’s many lakes.

His program is free and open to the public; registration is requested by calling ext. 4382 or e-mailing Details on the programs and other offerings of the Finger Lakes Institute are available by visiting FLI
