Project

The Brook Floater (Alasmidonta varicosa) is a stream-dwelling freshwater mussel native to the Atlantic Slope of the United States and Canada that has experienced large population declines over the last 50 years and is at high risk of extinction. This project will focus on strategies for achieving conservation for Brook Floater through multiple objectives: We will develop standardized surveys that will be conducted throughout partnering states to estimate abundances and predict occupancy of Brook Floater. We will develop species distribution models from the results of surveys from partnering states to inform future surveys and understand the habitat needs of Brook Floater.   We will develop propagation methods and build capacity for Brook Floater propagation throughout the range to aid in for population restoration. We will use structured decision making to focus monitoring design at the state and regional scale

Project

Climate change-driven shifts in distribution and abundance are documented in many species. However, in order to better predict species responses, managers are seeking to understand the mechanisms that are driving these changes, including any thresholds that might soon be crossed. We leveraged the research that has already been supported by the Northeast Climate Adaptation Science Center (NE CASC) and its partners and used the latest modeling techniques combined with robust field data to examine the impact of specific climate variables, land use change, and species interactions on the future distribution and abundance of species of conservation concern. Moreover, we documented biological thresholds related to climate variability and change for critical species in the Northeastern and Midwestern U.S. Our objectives were to identify the primary drivers (e.g
