The study is geared towards understand the role of California Roach (Hesperoleucas symmetricus), a native, non-threatened minnow in ecosystem functioning with an emphasis on response to shifting climate conditions. All fish will be collected from the South Fork Eel River, Mendocino County using dip net, seine, and/or minnow traps SCIN marked. A total number of 400 H. symmetricus will be collected, 400 of which will be sacrificed using MS-222 and preserved for later analysis. All experiments will be performed in stream reaches where roach are already present and no translocation will be involved. Research will be conducted using a three tiered approach incorporating stream-bank and snorkel surveys, in-stream enclosures, and the analysis of wild-samples. The data collected during the study will be part of an attempt to draw inferences on the response of H. symmetricus across various life history stages to temperature such as stage duration and resource utilization and implications on the species? role in community dynamics. Future applications of this data include modeling approximations of ecosystem productivity and nutrient availability across trophic levels as a function of both biotic and abiotic conditions.
