Lecture on motorized watercrafts affects on aquatic life presented today

A professor of zoology at Miami (Ohio) University will speak today at the University of Nevada, Reno on the effect of motorized watercraft on aquatic life.

James Oris was among the first researchers to link the toxicity impact of motorized watercraft emissions on fish and zooplankton at Lake Tahoe.

His research on a process known as photo-enhanced toxicity – a mixing of sunlight’s ultraviolet rays and emission chemicals in the water – is vital to understand how watercraft can impact high-altitude lakes such as Lake Tahoe, said Glenn Miller, interim director for UNR’s Center for Environmental Sciences and Engineering.

“As (photo-enhanced toxicity) progresses, it partitions into algae or small animals, increasing their toxicity dramatically,” Miller said. “This is a significant issue nationally, but most pointedly at Lake Tahoe.”

What: Presentation by James T. Oris on toxicity of motorized watercraft
