Conditions for growth and survival of bull trout in Beulah Reservoir, Oregon. Annual report 2001 Conditions for growth and survival of bull trout in Beulah Reservoir, Oregon. Annual report 2001
The Bureau of Reclamation (BOR) constructed Agency Valley Dam on the North Fork of the Malheur River in 1934-35, creating Beulah Reservoir. The project is operated and maintained by the Vale Irrigation District for irrigation and downstream flood control, with no minimum pool or outflow operational criteria. Although the project is not operated for fish and wildlife values, the reservoir...

Ecological resource management: A call to arms Ecological resource management: A call to arms
As the human population enlarges, it becomes increasingly difficult to sustain valued ecological resources. Human use of resources, whether it is the harvest of ocean fisheries, logging of forests, or farming of arable lands, has resulted in significant population declines in many wildlife species. The growth of urban areas and the expansion of impermeable surfaces alter landscape...

Elevated temperature exacerbates Ichthyophonus infections in buffalo sculpin Elevated temperature exacerbates Ichthyophonus infections in buffalo sculpin
High incidences of Ichthyophonus hoferi, a parasite primarily of marine and estuarine fishes, have recently been reported in rockfishes and Pacific herring from the eastern North Pacific (Kent et al 2001, Hershberger et al 2002). Taxonomic position of I. hoferi remains unresolved, but recent phylogenetic studies have grouped the organism with Dermocystidium, Psorospermium, the rosette...

Effects of acute thermal stress on the survival, predator avoidance, and physiology of juvenile fall Chinook salmon Effects of acute thermal stress on the survival, predator avoidance, and physiology of juvenile fall Chinook salmon
We subjected juvenile fall chinook salmon from the Hanford Reach of the Columbia River to acute thermal stressors in the laboratory that were derived from field data. We assessed the effects of thermal stress on: (1) the extent of direct mortality; (2) the vulnerability of fish to predation by smallmouth bass; and (3) some general physiological stress responses and synthesis of heat...

Monitoring and assessment of juvenile steelhead on Toppenish National Wildlife Refuge. Quick Response Project for 2001 Monitoring and assessment of juvenile steelhead on Toppenish National Wildlife Refuge. Quick Response Project for 2001
Toppenish National Wildlife Refuge (TNWR) in south central Washington was established in 1964 to provide an important link in the chain of feeding and resting areas for waterfowl and other migratory birds using the Pacific Flyway. Wetlands on TNWR include both natural floodplain wetlands along Toppenish Creek and man-made impoundments designed to mimic natural floodplain processes...

Characterization and isolation of an extracellular serine protease from the tomato pathogen Colletotrichum coccodes, and it's role in pathogenicity Characterization and isolation of an extracellular serine protease from the tomato pathogen Colletotrichum coccodes, and it's role in pathogenicity
Extracellular enzymes play an important role in the pathogenicity and virulence of phytopathogenic fungi. Several isolates of Colletotrichum coccodes, causal agent of anthracnose on tomato, were screened to determine the relationship between protease activity and virulence. A direct relationship was observed between extracellular protease activity and the induction of disease symptoms of...
