Mussels are considered one indicator of good water quality in rivers, but over the past 20 years mussel populations have continued to decline, while water quality improves. According to the Ohio Environmental Protection Agency (OEPA), water quality in the Cuyahoga River is now within safe levels for all parameters. However, what are safe levels for humans may not be safe for mussels. An analysis of freshwater mussel populations in two similarly sized watersheds, the Upper Cuyahoga River and Tinkers Creek was conducted. Correlations of mussel abundance and diversity were assessed by multivariate GIS/remote sensing tools to contrast water flow rates, …

Restoration outcomes can be variable and there is a need to understand the short- and long-term responses of the vegetation community. It is important to see if management goals are being met by evaluating restoration outcomes. Restoration goals often include establishing native species, increasing conservation value, and providing pollinator resources throughout the year. Assessing communities is commonly done though a taxonomic approach by using species presence and abundance. Another method of evaluation is through functional traits or species traits and their abundance. Both give different perspectives on how the community is achieving management goals. While taxonomic assessments can give insight …

Disturbance regimes, i.e. frequent fires, historically maintained oak barrens until European settlement patterns, and eventually, Smoky the Bear and the fire suppression campaign of the U.S. Forest Service snuffed out the periodic flames. In the absence of a disturbance regime, ground layer floral composition at many historical oak sand barrens will change predominantly because of a buildup of leaf litter and shading of the soils. Termed mesophication, this process of ecological succession will drive Black Oak Sand Barrens to an alternate steady state. A survey conducted on Singer Lake Bog in Green, Ohio, demonstrated that succession shifted the community to …
