Autecology, reproductive ecology, and demography of Astragalus australis var. olympicus (Fabaceae)

Creator:: Kaye, Thomas N.
Abstract:: The goal of this study was to gather information on the autecology, reproductive ecology, and population dynamics of Astragalus australis var. olympicus as a baseline for conservation strategies and to help explain its restricted range. Approximately four thousand individuals occurred in four known population centers in the Olympic Mountains, Olympic...

The effect of vitamin B-6 supplementation on plant protein utilization in adults

Creator:: Ruhumba-Sindihebura, Pascaline
Abstract:: We investigated the effect of pyridoxine supplementation on the utilization of protein in a low-protein, plant-based diet in four subjects (2 men and 2 women), aged 21 to 38 years. Following two days of a negligible protein diet, this 34 day study was divided into three dietary periods: the subjects...

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...

Allozyme genetics and mating systems of Cuphea Laminuligera and Cuphea lutea

Creator:: Krueger, Sharon K.
Abstract:: Cuphea laminuligera Koehne and Cuphea lutea Rose in Koehne are undomesticated species having potential as oilseed crops. Genetic markers and mating systems have not been described for these species. Our objectives were to survey these species for allozyme variation, analyze the segregation and linkage of polymorphic loci, estimate autofertility and...

Interspecific competition in young Douglas-fir plantations of the Oregon coast range

Creator:: Wagner, Robert Gordon
Abstract:: Improving vegetation management decisions in Pacific Northwest forests requires a better understanding of the interactions between planted conifers and associated vegetation. A practical index of interspecific competition, and quantitative models predicting conifer performance from such an index are particularly needed. To meet this need, neighborhood models of interspecific competition were...

Growth and carbon allocation of red alder seedlings grown over a density gradient

Creator:: Giordano, Peter A.
Abstract:: The amount and quality of competition among individuals in developing plant communities is an important factor determining community structure, composition and development. In perennial plant communities, this competition is reflected by shifts in carbon allocation among plant parts and can result in long-term structural differences between neighboring individuals. This study...

Effects of seed characters and competitive environment on two-year performance of open-pollinated Douglas-fir families

Creator:: St. Clair, John Bradley
Abstract:: Ungerminated seed and recent germinants from 39 open-pollinated Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) families were planted in each of three competitive environments in order to determine the degree to which growth differences among families are influenced by competitive environment, seed weight, and date of emergence. The three competitive...

Host suitability studies of Douglas-fir and white alder to the gypsy moth

Creator:: Joseph, Gladwin
Abstract:: Douglas-fir, Pseudotsuga menziesii and white alder, Alnus rhombifolia, species that are prevalent in the Pacific Northwest, were fed to larvae of the gypsy moth, Lymantria dispar L. Gypsy moth larvae from different familial lines (egg masses) from a single geographic population were evaluated on these hosts. The larvae were fed...

Primary productivity in the southeast Pacific Ocean : effects of enhanced ultraviolet-B radiation

Creator:: Behrenfeld, Mike J.
Abstract:: Anthropogenic releases of trace gases into the atmosphere are causing a decrease in stratospheric ozone concentrations and a subsequent increase in solar ultraviolet-B (UV-B)(280-320 nm) radiation reaching the earth's surface. The objective of this study was to determine the acute effects of enhanced UV-B radiation on the primary production of...
