Abstract (from Science of the Total Environment): Changes in climate are known to alter air temperature and precipitation and their associated thermal and hydrological regimes of freshwater systems, and such alterations in habitat are anticipated to modify fish composition in fluvial systems. Despite these expected changes, assessing climate change effects on habitat and fish over large regions has proven challenging. The goal of this study is to describe an approach to assess and identify stream reaches within a large region that are susceptible to climate changes based on responses of multiple fish species to changes in thermal and hydrological habitats occurring with changes in climate. We present a six-step...

Climate change is expected to alter the distributions and community composition of stream fishes in the Great Lakes region in the 21st century, in part as a result of altered hydrological systems (stream temperature, streamflow, and habitat). Resource managers need information and tools to understand where fish species and stream habitats are expected to change under future conditions. Fish sample collections and environmental variables from multiple sources across the United States Great Lakes Basin were integrated and used to develop empirical models to predict fish species occurrence under present-day climate conditions. Random Forests models were used to predict the probability of occurrence of 13 lotic fish...

The overall goal of the Midwestern regional-scale assessment was to identify river reaches in the Glacial Lakes Partnership regions (focusing on Michigan, Minnesota, and Wisconsin) that are most vulnerable to potential impacts of projected climate and land use changes. Because fish assemblages are strongly influenced by river water temperature and flow regimes, which are in turn affected by climate and land-use conditions, we will attempt to model fish habitat response to climate and land use changes through changes in temperature and flow. This project intended to: (1) develop three models that predict daily summer temperature for all river reaches in each state; (2) develop a single model to predict non-winter...

One goal of the National Scale Assessment included identifying regions and associated river reaches across the United States that are most vulnerable to projected climate and land use changes. As an initial attempt to characterize river system vulnerability, we followed the definition posed by Kasperson et al. (2006) that incorporates exposure of systems to stresses like climate and land use changes, sensitivity of systems to those changes, and system resilience. This project intended to provide (1) a framework of stream classification to assess vulnerability of fish habitat under future climate change, (2) a framework of stream classification to assess vulnerability of fish habitat with projected urban and agriculture...
