Ohio State University's experimental wetland research park seeks scientists

Ohio State University’s experimental wetland park sits nestled in a bend in the Olentangy River, where things are changing in Ohio’s capital city. The Wilma H. Schiermeier Olentangy River Wetland Research Park is in a rebuilding phase after the retirement of the original director, Bill Mitsch. He coordinated the construction of the wetlands, starting in 1992. Lynn McCready, interim director for the wetlands, is working to get more research underway at the facility. “Our primary focus of study will still be on the wetland ecology, but we do want to widen that focus to other aquatic ecosystems,†she said. The experimental wetland has opened its doors to scientists interested in doing research there.

Banking on a Wetland

Southwest Ohio’s first wetland mitigation bank is in early stages of development, but has already been deemed “great.†Five Rivers MetroParks, based in Dayton, saved 364 acres of earth from becoming a landfill to construct the Great Miami Wetland Mitigation Bank (GMWMB). A mitigation bank gives developers destroying wetlands the option to purchase credits that will make up for lost land resources. The GMWMB is the only bank in Ohio to offer stream restoration credits. It is also the only mitigation bank in Ohio to be owned, designed and managed by a conservation organization. The GMWMB will contain 61.2 acres of restored wetlands, 77.5 acres of wetland and riparian buffer, 220 acres of prairie and forested habitat and 4,920 linear feet of restored headwater stream habitat.

Acidification May Ease Struggle to Survive for Herring Larvae

Survival in the ocean is no easy task, especially for ichthyoplankton, the eggs and larvae of fish. For most, including herring larvae, once they're released into the water, they're on their own, with survival as their sole goal. Climate change is making that goal more difficult to obtain for many species, but the changes to the marine atmosphere that come along with a warming climate are complex, and they affect various species in different ways. Scientists are still trying to research what some of those differences might look like. Struggle for survival Ichthyoplankton are vulnerable to predators, of course, but they are also highly sensitive to their environment. This means changes in dissolved oxygen levels, temperature, and pH can all be dangerous to fish eggs and larvae.
