Long-Term Trends Of Stream Fish Community Assemblages In Southern Missouri With Contemporary Land Use Impacts, Stephanie Marie Sickler
Long-Term Trends Of Stream Fish Community Assemblages In Southern Missouri With Contemporary Land Use Impacts, Stephanie Marie Sickler
MSU Graduate Theses
Stream fish communities in the Ozarks are structured via a number of different mechanisms, including basin, stream size, and human land use. The purpose of this study was to understand the structuring mechanisms of stream fish communities in southern Missouri. I compiled 48 years of historical fish collections performed by the Ichthyology class at Missouri State University consisting of 140 sites. I resampled 45 of these sites in summer of 2016. First, I tested whether communities are different between basins and stream size. Next, I tested associations of land use at three spatial scales to local fish communities. Last, I …
Comparison Of Habitat And Water Quality In The Blue River's South And Salem Forks In Southern Indiana To Support Watershed Management, Erin Crone
Undergraduate Theses
A stream’s habitat and water quality are heavily influenced by land use and geology within its watershed. Pollutants and sediment loading from watershed drainage can make streams less habitable for certain species, reducing biodiversity. Watershed management strategies, such as the promotion of best management practices in agriculture, can help to combat stream degradation from watershed inputs. The upper Blue River in southern Indiana is a biodiversity hotspot but is experiencing degradation and biodiversity loss due to watershed inputs. This is exemplified by the disappearance of the eastern hellbender salamander, an indicator species, from this area. Fine sediment loading is particularly …
