Rotifers and brine shrimp (Artemia) are important prey items for rearing marine fish larvae. Their availability in the water column may be reduced when they are transferred to larval rearing tanks at lower temperature. In this study, Brachionus rotundiformis (SS-type) and Brachionus plicatilis (L-type) were semi-continuously cultured and fed on...

Effects of temperature transfer on availability of
The temperature of the water in our
streams and rivers is very important to the
well-being of fish and other aquatic organisms.
Most species need cool water to
survive. As a result, Oregon’s water-quality
standards include maximum stream temperature
criteria. Streams that are monitored
and found to exceed these temperatures...
The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...

Title: Monitoring River Restoration using Fiber Optic Temperature Measurements in a
Modeling Framework
The Middle Fork of the John Day River (MFJD) in Northeastern Oregon contains important spawning grounds for spring Chinook and summer steelhead of the Columbia River Basin. In the summer of 2008 phase one of a river restoration project was completed which included the addition of engineered log jams (ELJs)...
It is well established that individual organisms can acclimate and adapt to temperature to optimize their functioning. However, thermal optimization of ecosystems, as an assemblage of organisms, has not been examined at broad spatial and temporal scales. Here, we compiled data from 169 globally distributed sites of eddy covariance and...
Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are considered as they apply to four calibration methods for single-ended DTS installations. The new methods presented are more accurate than...

The typically sparse distribution of weather stations in mountainous terrain inadequately resolves temperature variability. Accordingly, high‐resolution gridding of climate data (for applications such as hydrological modeling) often relies on assumptions such as a constant surface temperature lapse rate (i.e., decrease of surface temperature with altitude) of 6.5°C km⁻¹. Using an...
Raman spectra distributed temperature sensing (DTS) by fiber-optic cables has
recently shown considerable promise for the measuring and monitoring of surface and
near-surface hydrologic processes such as groundwater–surface water interaction,
borehole circulation, snow hydrology, soil moisture studies, and land surface energy
exchanges. DTS systems uniquely provide the opportunity to monitor...
