Abstract:: Oxygen uptakes of Douglas-fir beetles collected during November 1969 through April 1970 were measured at different experimental temperatures. The oxygen uptakes of adult beetles increased at each experimental temperature as the seasons progressed from winter to spring. The larval and pupal Douglas-fir beetles, collected in February 1970, had lower oxygen...

Abstract:: Microtus canicaudus Miller, the gray-tailed vole, was studied in the field and laboratory in order to clarify aspects of the relationship of this species to its habitat. All trapping and sampling was done on permanent pasture land in the William L. Finley National Wildlife Refuge 12 miles south of Corvallis,...

Abstract:: A method was developed for converting the food producing capabilities of Oregon's soils to numerical data from which state and county carrying capacities for human populations could be calculated. Another method was developed for converting the needs for housing and related support construction to numerical data which would consume cultivated...

Abstract:: A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...

Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

Abstract:: Abbott Creek Natural Area is a 2600 acre research area of the Mixed-Conifer forest type. This study delineated plant association units within the area, and demonstrates the use of the computer program SIMORD as a tool in the definition of such associations. One hundred fourteen sites were sampled by a...
