dc.description.abstract Unionids are considered ecosystem engineers in aquatic ecosystems, but they are endangered because of human-induced changes that have altered their habitat and negatively impacted their ecophysiology. Environmental stressors (conditions that exceed their normal range of variation) do not act alone, rather they interact as multiple stressors. The goal of this study was to examine how changes in temperature, total suspended solids (TSS) and flow affected the clearance rates (CR) and oxygen consumption (OC) of Lampsilis siliquoidea in laboratory experiments. The CR and OC of L. siliquoidea increased with acclimation temperature and water velocity, and decreased with TSS concentration and exposure to acute temperature change. The main stressor effects depended on acclimation temperature; temperature was the primary stressor at 12.5°C, velocity at 20°C, and TSS concentration at 27.5°C. These results provide information on the effects of multiple stressors on mussel ecophysiology which will inform policy decisions regarding their conservation. en_US
