Ohio Sea Grant Researchers Study Microbe Diversity in Lake Erie
Ohio Sea Grant researchers at The University of Toledo have conducted a study over the past two summers to examine the diversity of bacteria and algae in Lake Erie. These microorganisms play a crucial role in the lake’s ecosystems by providing energy through photosynthesis for the entire aquatic food web.
Importance of Microbes in Ecosystems
Microbes are both the foundation of a healthy ecosystem and a potential source of issues for humans and other organisms. Understanding their interconnections, functions, and roles within the lower food web is vital for assessing the overall health and resilience of Lake Erie’s ecosystem.
Research Methodology
The research team, led by Trisha Spanbauer, assistant professor of environmental sciences at The University of Toledo, collected aquatic microbes from nine sample sites along the shoreline. These sites represented different land uses and shoreline management techniques, including areas with agricultural and industrial impact, as well as intact wetlands. The collected samples were then subjected to DNA analysis using high-throughput sequencing to identify species, genus, or family and quantify the diversity of the microbiome.
Data Analysis and Implications
The team is currently analyzing the collected data to identify resilient and vulnerable environments in the lake. This information will be shared with partner agencies, such as the Ohio Department of Natural Resources Coastal Management Office and the Old Woman Creek National Estuarine Research Reserve. The results may also help identify ecological indicators that can predict changes in the ecosystem before it reaches a state where it no longer provides essential services.
Preliminary data suggests that silica, along with factors like temperature and stratification, may influence competition among algae and contribute to harmful algal blooms. Silica is abundant in the Great Lakes and is found in minerals like quartz and sandstone.
Community Science Initiative: ERIeDNA
As part of the project, Spanbauer’s team has initiated a community science program called ERIeDNA. This program involves University of Toledo students and local residents in the research process. Participants collect water samples from nearby sources, filter them, and return the filters to the researchers for analysis. Spanbauer plans to expand the program and create kits that people can use to collect and filter water samples.
“This technique is easy to implement, and sequencing has become more affordable. It provides an opportunity for everyone to better understand these microscopic organisms that sustain healthy fisheries in the Western Basin,” said Spanbauer.
