ASSESSING CONTEMPORARY DISTURBANCE AND CLIMATE CHANGE RISKS FOR MICHIGAN’S VULNERABLE STREAM FISHES
We assessed the vulnerability of stream fishes of greatest conservation need in Michigan to current and future environmental threats. We first developed habitat suitability models for 27 stream fishes using MaxEnt, incorporating current stream temperature and flow estimates as predictors. We then developed future habitat suitable projections using 13 climate change models for mid and late century. Model results were then used to examine both the individual and combined vulnerability of highly suitable stream habitats to habitat fragmentation, anthropogenic landscape disturbances, and climate change. Warmwater and large river fishes gained habitat under climate change due to increased water temperatures and stream flows, while coolwater and coldwater fishes are projected to lose habitat. Analysis of fragmentation among streams habitats indicates high levels of fragmentation for many stream fishes. In addition, nearly 53% of highly suitable stream fish habitats are moderately to severely disturbed from agriculture and urban development. Assessing multiple threats to stream fish habitats, both contemporary and future, is needed to provide information vital to ongoing stream fish conservation efforts.
