The ecology of Mountain Quail in Oregon

Creator:: Pope, Michael D. (Michael Dickens)
Abstract:: Mountain Quail (Oreortyx pictus) populations have declined in many areas of the western Great Basin during the past century. Yet the life history of this species is little known. From 1997 to 2000, I studied radio-marked Mountain Quail in Hell's Canyon in northeastern Oregon, in the Cascade Mountains of southwestern...

Geomorphic influences on habitat formation, distribution, and development and the classification of upland coastal Oregon streams

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Response of avian communities to herbicide-induced vegetation changes, western Oregon

Creator:: Morrison, Michael L.
Abstract:: The relationships between avian community structure and herbicide modification of vegetation were analyzed on early-growth clearcuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. Only minor effects of herbicide treatment were evident 1-year after spraying, except for red adler (Alnus rubra), which still exhibited...

Golden Eagles in Denali National Park and Preserve : productivity and survival in relation to landscape characteristics of nesting territories

Creator:: McIntyre, Carol L.
Abstract:: Denali National Park and Preserve (Denali) contains one of the highest densities of nesting Golden Eagles (Aquila cluysaetos) in North America. Productivity of this migratory population varies both temporally and spatially. Regardless of prey abundance, more fledglings are consistently produced at some nesting territories than others. In many raptor studies,...

Stress, osmoregulation, and the hormone cortisol in yearling coho salmon, Oncorhynchus kisutch

Creator:: Redding, Joseph Michael
Abstract:: Freshwater (FW) and seawater (SW) acclimated yearling coho salmon, Oncorhynchus kisutch, were subjected to severe confinement stress in FW, SW, or a medium (1/3 SW) that was approximately isosmotic to the fish's blood. Chronic stress caused osmotic imbalances in FW and SW, but not in 1/3 SW. In SW, blood...

The adaptive significance of certain enzyme polymorphisms in steelhead trout (Salmo gairdneri)

Creator:: Redding, Joseph Michael
Abstract:: Mean weights, lengths, and condition factors of three isozyme phenotypes of lactate dehydrogenase (LDH) enzyme differed significantly for experimentally reared winter steelhead trout (Salmo gairdneri) fry. Time of emergence from the gravel was unrelated to LDH phenotype. Relative mortality of the phenotypes between eyed-egg stage and emergence was unaffected by...

Utilization of mineral sites by bandtailed pigeons

Creator:: Passmore, Michael Forrest
Abstract:: The occurrence of band-tailed pigeons (Columba fasciata) three mineral sites in Western Oregon was studied during the summers of 1974-1976. Objectives of the study were o: determine seasonal patterns of utilization of mineral sites by pigeons of different sex and age classes; determine productivity of pigeon populations associated with Mineral...

Biology of the Rex sole, Glyptocephalus zachirus Lockington, in waters off Oregon

Creator:: Hosie, Michael J.
Abstract:: Data are presented on the life history and population dynamics of rex sole (Glyptocephalus zachirus Lockington) collected from Oregon waters between September 1969 and October 1973. Length-weight relationships vary little between sexes or with time of year. Otolith annuli form primarily from January through May and were used for age...
