LANDSCAPE ASSOCIATIONS WITH NATIVE AND INVASIVE FRESHWATER MUSSELS IN THE KALAMAZOO RIVER, MI, USA
Understanding threats that imperiled organisms like freshwater mussels face is imperative for aquatic management. Knowledge of the ways in which freshwater mussels interact and are influenced by the environment provides insight into the focus of management and conservation actions. This study examined the impacts of land use, surficial geology, and slope on native freshwater mussel (unionid) and invasive mollusk (corbiculid) abundance, as well as unionid species richness, in the Kalamazoo River, Michigan, USA using data collected in 2018 and 2019. GIS and Spearman's rank correlation analyses at multiple spatial scales indicated that relationships exist among unionid richness and abundance or corbiculid abundance and various land use and geology types within the watershed. In addition, different species of freshwater mussels exhibit varying relationships with differing land use and geology types. Our results emphasize the need to incorporate spatial information into our understanding of the relationships between organisms and their environments and contribute to existing evidence of the impacts that landscape factors can have on the abundance and distribution of both native and invasive organisms.
