Linking stream fish thermal ecology and adaptive capacity to inform watershed-based management and Species Status Assessments

The response of many aquatic organisms to altered water temperatures is unknown, complicating efforts to manage their populations. Managers may benefit from better estimates of thermal metrics such as species-specific temperature tolerances and optima by applying that knowledge in conservation planning frameworks. We will estimate several temperature metrics for two species of fish (Ozark Shiner and Blacknose Shiner) and work with state and federal agency managers from Missouri, Iowa, and Arkansas, and the US Fish and Wildlife Service (USFWS) and The Nature Conservancy to prioritize stream reaches for conservation. This project will directly inform the Ozark Shiner USFWS Species Status Assessment (SSA). Products will include data on the thermal tolerance and adaptive capacity of Ozark and Blacknose Shiner, coupled with priority ranking of Missouri stream segments (and other states, if data are available).
