Ohio Sea Grant

Ohio Sea Grant looks at relationship between smallmouth, invasive round goby in Lake Erie

For humans, if the temperature rises by a few degrees, the immediate impact is minimal. Some people might peel off a layer of clothing. Others might not even notice a difference.
But for fish living in Lake Erie, such a temperature increase in water could spell disaster. Fish are ectotherms, meaning that their body temperature is dictated by the water they live in. As water heats up, fish metabolism increases, causing fish to work faster and use up more energy.

Microbe diversity at heart of new Lake Erie study

Ohio Sea Grant researchers at the University of Toledo spent the past two summers collecting samples of various bacteria and algae at sites across the region’s shoreline to study microbe diversity. The tiny organisms are critical to Lake Erie’s ecosystems, providing energy for the entire aquatic food web through photosynthesis.
“There’s this tension between microbes being the foundation of a healthy ecosystem but also potentially something that can cause issues for humans and other organisms,” said Trisha Spanbauer, assistant professor of environmental sciences at the University of Toledo. “So, better understanding the players, how they’re connected to each other, and their functions within the lower food web is really vital to understanding the health of that ecosystem and the resilience overall.”

Opportunities to explore Lake Erie science and history offered on Ohio’s South Bass

Visitors to South Bass Island once again have the chance to explore Lake Erie science and history at the South Bass Island Lighthouse, the Aquatic Visitors Center, and on Gibraltar Island this summer.
The South Bass Island Lighthouse is located at the southwest tip of the island and was in operation until 1962. The lighthouse grounds are open to the public dawn to dusk free of charge unless otherwise posted. Free tours will be offered from 11 a.m. to 5 p.m. Friday, July 14 and Friday, Aug. 11.

Sea Grant research could inform decisions on migrating songbirds

New research indicates nocturnal migrating songbirds might rely on archipelagos like North, Middle, and South Bass islands on Lake Erie as a navigation aid or resting place.

“Lake Erie is a barrier for migrating birds. It’s not huge like the Gulf of Mexico, but there are 30 to 40 miles between Ohio and Canada, and a bird that gets in trouble over water is going to have a large problem,” said Verner Bingman, distinguished research professor of neuroscience in the Department of Psychology at Bowling Green State University.
