The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

Creator:: Evans, Allison N.
Abstract:: Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...

Effects of habitat manipulations on California quail in western Oregon

Creator:: Oates, Russell M.
Abstract:: The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...

The effects of rotational grazing and prescribed burning on bobwhite populations in south Texas

Creator:: Wilson, Marcia H.
Abstract:: Short-term effects of 3 grazing systems and prescribed burning on bobwhite (Colinus virginianus) populations were investigated on the Welder Wildlife Refuge near Corpus Christi, Texas, during spring (April through June) and fall (September through October) of 1976 and 1977. Two rotational systems, high intensity-low frequency (HILF) and four-pasture, deferred-rotation (4PDR),...

Ecology and behavior of bison in the Henry Mountains, Utah

Creator:: Van Vuren, Dirk
Abstract:: Aspects of bison ecology and behavior were studied in the Henry Mountains, Utah during summer 1977 and summer 1978. Foraging distributions of bison and of cattle were compared to elevation, slope, horizontal distance from water, vertical distance from water, aspect, and availability of preferred forage. The effect of bison-cattle interactions...

Revegetation with Carex nebrascensis and Carex utriculata following reconstruction in a NE Oregon meadow stream

Creator:: Quistberg, Sarah E.
Abstract:: Riparian vegetation is an essential component for the maintenance and/or repair of channel stability and function. Sedges within low-gradient riparian systems provide the structure necessary for sediment trapping leading to channel narrowing through bank building processes. Planting success in riparian restoration projects has often failed due to inappropriate species selection,...

Habitat parameters associated with the distribution of seven willow species on a stream in southeastern Oregon

Creator:: Gilbert, Griffith J.
Abstract:: Thirteen different habitat parameters were measured either quantitatively or qualitatively around seven different Salix (willow) species on a defined reach of stream on the southwestern slope of Steens Mountain in southeastern Oregon in order to both broaden the current information base of riparian ecology and inform future willow plantings aimed...

Comparative ecology of bobwhite and scaled quail in southern Texas

Creator:: Wilson, Marcia H.
Abstract:: For my research goals I addressed the theoretical importance of competition in habitat selection of 2 quails and examined the use of resources in peripheral and core areas. Methodological objectives were to determine cover and food selection of Texas bobwhite (Colinus virginianus texanus) and chestnut-bellied scaled quail (Callipepla squamata castanogastris)...

Sediment potentials for selected ecological land units in central Oregon

Creator:: Mattison, Jeffrey L.
Abstract:: During the summers of 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of Crook County, in central Oregon. The Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a...

Seasonal response of bitterbrush to burning and clipping in eastern Oregon

Creator:: Clark, Robert G.
Abstract:: Bitterbrush [Purshia tridentata (Pursh) DC] plants were burned or clipped, fall and spring, under different soil moisture conditions on two sites in east-central Oregon. Treatments, on plants of an erect growth form on the Juniperus/Artemisia-Purshia site resulted in 38% of the fall-clipped and 40% of the spring-clipped plants sprouting. None...
