Water Temperature in Rivers and Streams Active
Increases in summer stream temperature as a result of human impacts and climate change may exceed the thermal tolerances of aquatic biota that are adapted to colder environments and climates. The combined effects of humans and climate change are of global concern across the range of coldwater aquatic organisms.
We use state-of-the-art technology and techniques to quantify spatial and temporal variability in stream temperature using field surveys, remote sensing, and spatially explicit modeling. This information is used to understand and predict the effects of climate change, riparian management, and restoration on cold-water habitats and the thermal diversity of rivers and streams.

Filter Total Items: 16Temperature-associated population diversity in salmon confers benefits to mobile consumers
Habitat heterogeneity can generate intraspecific diversity through local adaptation of populations. While it is becoming increasingly clear that population diversity can increase stability in species abundance, less is known about how population diversity can benefit consumers that can integrate across population diversity in their prey. Here we demonstrate cascading effects of thermal heterogeneiAuthorsCasey P. Ruff, Daniel E. Schindle, Jonathan B. Armstrong, Kale T. Bentle, Gabriel T. Brooks, Gordon W. Holtgrieve, Molly T.

The Lower Crooked River is a remarkable groundwater-fed stream flowing through vertical basalt canyons in the Deschutes River Valley ecoregion in central Oregon (Pater and others, 1998). The 9-mile section of the river between the Crooked River National Grasslands boundary near Ogden Wayside and river mile (RM) 8 is protected under the National Wild and Scenic Rivers Act (16 U.S.C. 1271-1287) forAuthorsChristian E.

We quantified distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel-unit, reach-, and section-level spatial scales in a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. We investigated the effectiveness of thermal remote sensing for analyzing spatial pAuthorsChristian E. Torgersen, David M. Price, Hiram W. Li, B.A. McIntosh
