Influences of riparian canopy on aquatic communities in high desert streams of eastern Oregon

Creator:: Tait, Cynthia K.
Abstract:: Because riparian canopy controls most energy inputs to stream ecosystems, it directly affects the structure of aquatic food webs and the ecological processes that govern interactions among trophic levels. This study addresses the interdependence among riparian canopy, benthic community structure, and the carrying capacity of high desert streams for salmonid...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Habitat use by female greater sage grouse in relation to fire at Hart Mountain National Antelope Refuge, Oregon

Creator:: Byrne, Michael W.
Abstract:: The United States Fish and Wildlife Service currently uses fire as a management tool to improve Greater Sage Grouse (Centrocercus urophasianus Bonaparte) nesting and brood-rearing habitat at Hart Mountain National Antelope Refuge (HMNAR) in S.E. Oregon. Previous studies at HMNAR revealed use of burned areas by sage grouse throughout the...

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...

Comparative behavior of the progeny of hatchery and wild steelhead trout (Salmo gairdneri)

Creator:: Bieber, Glen F.
Abstract:: The objectives of this study were to determine whether changes in the selective pressures which occur in a hatchery could cause inherited modifications in the behavior of steelhead trout (Salmo gairdneri) that would affect their survival in the wild. Environmental effects on the behavior of the offspring of hatchery and...

Effects of inbreeding Coho salmon (oncorhynchus kisutch)

Creator:: Solazzi, M. F. (Mario Frank)
Abstract:: Effects of inbreeding coho salmon (Oncorhynchus kisutch) on survival during early life history, growth, feed efficiency, and resistance to gas bubble disease were studied. No effect of inbreeding could be associated with either F=0.25 or F=0.125. Tetraploidy may help explain the absence of inbreeding depression at these levels.

An analysis of guild structure of avian communities, Columbia River, Oregon

Creator:: Noyes, Cecilia Lea Barham
Abstract:: Effects of habitat and season on guild structure of avian communities were examined for islands in the estuary zone of the Columbia River, Oregon. Bird species were classified into guilds according to their major food item, typical foraging substrate, and foraging behavior. Variation in community structure indices (number of guilds,...

Determination of marine migratory behavior and its relationship to selected physical traits for least cisco (Coregonus sardinella) of the western Arctic coastal plain, Alaska

Creator:: Seigle, John C.
Abstract:: With increased resource development on the western Arctic coastal plain of Alaska (especially within the oil extraction industry) it is important to understand the basic life history attributes of whitefish stocks in the region in order to ensure appropriate management. These fish are a crucial part of subsistence harvests for...
