Measurements on growth traits up to 41 years of age
from 68 progeny sites in eight first-generation breeding
zones of coastal Douglas-fir (Pseudotsuga menziesii
[MIRB.] FRANCO var. menziesii) in the US Pacific Northwest
were used to investigate age trends of genetic parameters
and to determine optimum age of selection. Heritabilities...
Distribution and life history characteristics of lacustrine-adfluvial bull trout (Salvelinus
confluentus) were described in the North Fork Skokomish River Basin (including Lake
Cushman, a reservoir) from 1994 to 1996. Day snorkeling was conducted in the river to

I am particularly interested in Snyder's thoughts on how language relates to nature. I focus primarily on Snyder's prose in attempts to understand...
From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...
The purpose of this study was to assess the attitudes of teachers at the
elementary, middle, and high school levels toward student rights and
classroom management. Specifically this study was designed to analyze the
effect Judicious Discipline: A Constitutional Perspective for School Rules and
Decisions had upon teacher attitudes toward...
