Resource Type:: Dissertation

A dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

Creator:: White, Robert Lewis, II
Abstract:: Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...

An assessment of southern Oregon clearcut and shelterwood cut cover types using LANDSAT MSS digital and supporting aircraft data

Creator:: Hawley, David Llewellyn
Abstract:: The feasibility of utilizing LANDSAT MSS data in assessing surface cover types and areal extent of clearcut and shelterwood cut harvest sites in southern Oregon was investigated. The research utilized extensive 'ground truth' information to evaluate the LANDSAT data. A three faceted ground truth collection scheme analyzed 1) U.S. Forest...

Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Systematics of the salamander genus Dicamptodon strauch (Amphibia: Caudata: Ambystomatidae)

Creator:: Nussbaum, Ronald A.
Abstract:: Dicamptodon is the single, extant genus of the ambystomatid subfamily Dicamptodontinae. Two species, D. ensatus (Eschscholtz) and D. copei Nussbaum are recognized. D. ensatus is found in the forested, mountain regions of northwestern California and western Oregon, in the Willapa Hills and Cascade Mountains of Washington, in extreme southwestern British...

Patterns of energy utilization in the litter subsystem of a Douglas-fir forest

Creator:: Chase, Wallace T.
Abstract:: Respiratory rates were measured, in situ, for the litter, the soil, and the litter-soil subsystems of a Pseudotsuga menziesii forest as a function of type of understory vegetation. The major objectives were to demonstrate the utility of the litter layer as a distinct subsystem of this forest ecosystem, to demonstrate...

A computer simulation model of land use dynamics in the State of Oregon

Creator:: Calligan, C. C.
Abstract:: The dynamics of land use in the State of Oregon are simulated on a digital computer. The introductory chapter outlines the complex nature of the problems facing the post-industrial society and argues that the scientific and professional estates share in the responsibility for public policy formulation. The second chapter .presents...
