Potential for dispersal of the non-native parasite Myxobolus cerebralis : qualitative risk assessments for the state of Alaska and the Willamette River Basin, Oregon

Creator:: Arsan, E. Leyla
Abstract:: First introduced to the USA in 1958, Myxobolus cerebralis, the parasite responsible for whirling disease in salmonids, has since spread across the country causing severe declines in wild trout populations in the intermountain west. Recent development of risk assessment models used to assess the likelihood and consequences of exotic parasite...

Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:: Momoda, Tracey S.
Abstract:: The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

An analysis of consumer response to environmentally certified, ecolabeled forest products

Creator:: Anderson, Roy Carl
Abstract:: Historically, researchers have used surveys, focus groups, and anecdotal evidence to evaluate consumer response to environmentally certified, ecolabeled forest products. These methods generally measure consumer attitudes toward certified forest products. Since the strength of the correlation between attitudes and behavior has long been questioned, consumer response to certified forest products...

Some effects of testosterone on cichlid fish, Cichlosoma bimaculatum (Linnaeus)

Creator:: Heitz, David Carl
Abstract:: The effects of testosterone were studied on the tropical fish, Cichlasoma bimaculatum. Growth experiments were designed to determine how testosterone influenced the food consumption and growth of fish. Starvation experiments were designed to show the effects of testosterone on the basal rate of utilization of body energy stores and to...

Testing and evaluation of flexural reinforcing bars terminating in columns

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...

Food habits, dietary overlap and gastric evacuation rates of rockfishes (genus Sebastes)

Creator:: Brodeur, Richard D.
Abstract:: Euphausiids constituted the major food of five co-occuring species of rockfishes (Sebastes spp.). Copepods, decapods, cephalopods, amphipods, fishes and other pelagic prey were also consumed but were less important to the overall diet. Two species, S. flavidus and S. diploproa, were relatively euryphagous, utilizing a high number of prey taxa....

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
