Abstract: The overall research goal is to understand the composition and changes in cryptic nongame fish species composition associated with increases in temperature. The investigator will address this research goal with two specific research objectives: (1) Define the cryptic species, their distributions, and habitat use by describing currently unknown sculpin species within the Clark Fork River basin (and determine their status as a likely exotic species). (2) Assess potential responses of sculpin assemblages to temperature gradients through determining thermal tolerances and temperature-dependent competition. Link these results with current distributions to explore the vulnerability to these species to changing stream temperatures.
