Arid lands of the Southwest Arid lands of the Southwest
When thinking about plants and animals that inhabit hot arid lands of the southwestern U.S., fish are easily overlooked by most people. However, these desert lands often contain isolated springs or cienegas (a Spanish term referring to permanently saturated 'seep wetlands') and streams supporting native fishes that occur no where else in the world. These aquatic remnants from the last...

The Columbia River Research Laboratory The Columbia River Research Laboratory
The U.S. Geological Survey's Columbia River Research Laboratory (CRRL) was established in 1978 at Cook, Washington, in the Columbia River Gorge east of Portland, Oregon. The CRRL, as part of the Western Fisheries Research Center, conducts research on fishery issues in the Columbia River Basin. Our mission is to: 'Serve the public by providing scientific information to support the...

Fish can get diseases too Fish can get diseases too
Infectious diseases are increasingly recognized as an important component of the ecology of fish in the wild. Many of the viral, bacterial, protozoan and fungal pathogens of fish that were initially discovered in captive fish have their origin among wild populations; however, the impact of disease among these free-ranging stocks has been difficult to study. At the WFRC, combinations of...

Distribution, migration behavior, habitat use, and species interactions of fall-released juvenile hatchery spring Chinook salmon on the Deschutes River, Oregon, 2002, Annual report 2002 Distribution, migration behavior, habitat use, and species interactions of fall-released juvenile hatchery spring Chinook salmon on the Deschutes River, Oregon, 2002, Annual report 2002
In a review of National Fish Hatcheries (NFH), the U.S. Fish and Wildlife Service (USFWS) identified the need to assess the fate of hatchery-reared fish and their potential effect on the aquatic community (USFWS 1998). Additionally, in the Columbia River Biological Opinion, the National Marine Fisheries Service (NMFS) recommended monitoring and evaluating ecological interactions between...

Assessment of smolt condition: Biological and environmental interactions -- The impact of prey and predators on juvenile salmonids Assessment of smolt condition: Biological and environmental interactions -- The impact of prey and predators on juvenile salmonids
The Bonneville Power Administration (BPA) has funded the Assessment of Smolt Condition project since 1987. During that time the project changed frequently to meet the information needs of fish managers by conducting studies throughout the Columbia River basin. Past research has examined the influence of smolt physiological development and health on migration rate; differences in...

Photosynthesis and fluctuating asymmetry as indicators of plant response to soil disturbance in the Fall-Line Sandhills of Georgia: a case study using Rhus copallinum and Ipomoea pandurata Photosynthesis and fluctuating asymmetry as indicators of plant response to soil disturbance in the Fall-Line Sandhills of Georgia: a case study using Rhus copallinum and Ipomoea pandurata
We examined net photosynthesis, transpiration, stomatal conductance, and leaf fluctuating asymmetry on two species (Rhus copallinum and Ipomoea pandurata) as indicators of stress at nine sites across a gradient of soil disturbance at Fort Benning, Georgia. There were three sites for each of three disturbance levels. Physical habitat disturbance was caused by activities associated with...

Juvenile and adult fall Chinook and chum salmon habitat studies below Bonneville Dam on the Columbia River. Annual report 2002-2003 Juvenile and adult fall Chinook and chum salmon habitat studies below Bonneville Dam on the Columbia River. Annual report 2002-2003
We investigated spatial and temporal changes in subyearling fall Chinook salmon rearing habitat and areas dewatered below Bonneville Dam on the Columbia River. We used two-dimensional hydrodynamic modeling to predict water velocity and depth data. By combining two-dimensional hydrodynamic modeling with a predictive model of subyearling rearing presence, we were able to illustrate...
