Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Stone Lab: Cyanobacteria Monitoring in Ohio Lakes
Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.

From Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing
Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
