Developmental instability: measures of resistance and resilience using pumpkin (Cucurbita pepo L.) Developmental instability: measures of resistance and resilience using pumpkin (Cucurbita pepo L.)

Fluctuating asymmetry measures random deviations from bilateral symmetry, and thus estimates developmental instability, the loss of ability by an organism to regulate its development. There have been few rigorous tests of this proposition. Regulation of bilateral symmetry must involve either feedback between the sides or independent regulation toward a symmetric set point. Either kind of

Susceptibility of zebrafish (Danio rerio) to a model pathogen, spring viremia of carp virus Susceptibility of zebrafish (Danio rerio) to a model pathogen, spring viremia of carp virus

To improve our understanding of the genetic basis of fish disease, we developed a pathogen model, using zebrafish (Danio rerio) and spring virema of carp virus (SVCV). Replicate groups of 10 fish were acclimated to 20 or 24°C, then were exposed to SVCV concentrations of 103 to 105 plaque-forming units per milliliter (PFU/ml) of water and observed daily. In a second trial, fish were...

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...
