Immediate effects of acute stress on innate immunity in rainbow trout (Oncorhynchus mykiss)

Creator:: Demers, Nora Egan
Abstract:: This thesis tests the hypothesis that innate immunity may be enhanced immediately following a stressful event. The experiments characterize the acute effects of the fight or flight response on some immunological and endocrine parameters in rainbow trout (Oncorhynchus mykiss). Plasma cortisol and catecholamines were elevated within seconds of the initiation...

Does intensive forest management affect innate immunity of wild deer mice (Peromyscus maniculatus)?

Creator:: Rogers, Natalie M., Hanselmann, Rhea, and Jolles, Anna E.
Abstract:: To examine the influence of forest management on wildlife immunity, the innate immune system of wild deer mice (Peromyscus maniculatus) inhabiting forest plots of different management intensities in the Oregon coast range was measured by bactericidal assay. Bactericidal activity was compared across three management levels, including 40-50 year old forest...

Changes in coral reef symbiont density during acclimation and stress

Creator:: Ton, Hayden, Dziedzic, Katherine, and Meyer, Eli
Abstract:: Coral reefs have become extremely vulnerable to rising ocean temperatures, with mass bleaching events increasing in frequency and severity. If bleaching events persist annually, models predict that more than 90% of reef species will face long-term degradation. However, recent evidence has shown that corals may be able to thermally acclimate...

Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...

The energetic response to handling stress in juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Davis, Lawrence E. (Lawrence Edward), 1965-
Abstract:: Various aspects of the energetic response to handling stress in juvenile coho salmon (Oncorhynchus kisutch) were examined. Fish were subjected to four different handling stressors in a Blazka-style respirometer. Stressed fish had rates of oxygen consumption that were higher than controls. The magnitude of the increase ranged from 139 to...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Behavioral and physiological indicators of stress in sablefish, Anoplopoma fimbria

Creator:: Spencer, Mara L.
Abstract:: The development of assays for stress in marine fishes is vital for studying the impacts of bycatch in fisheries and for determining the health of fish being cultured or used in research. This research developed behavioral and physiological assays for stress in juvenile sablefish, Anoplopoma fimbria, a species that comprises...

Early development of the endocrine system in salmonids : regulation of sex differentiation and ontogeny of the stress response

Creator:: Floyd, Donald J.
Abstract:: Sex steroids, follicle stimulating hormone (FSH), luteinizing hormone (LH) and gonadotropin releasing hormone (GnRH) were measured in monosex and mixed sex populations of rainbow trout during early development. Steroids declined following fertilization, increased at hatch, then fell and remained constant thereafter. Trends toward differences in steroids between males and females...

Rapid effects of corticosterone on stress-related behaviors in an amphibian

Creator:: Chiavarini, Katherine E.
Abstract:: In the wild, when an animal is exposed to predators or harsh conditions, the stress response is often associated with fleeing behaviors, which are seen as increased locomotor behavior. Handling-stress procedures and intracerebroventricular (icy) injection of corticotropin-releasing factor (CRF) have both been shown to cause an increase in locomotor activity...
