A taxonomic investigation was made of 24 taxa belonging
to the section Trichodium (Michx.) Trin., of
Agrostis, and the genus Podagrostis. Experimental methods
were employed, including: uniform garden culture of transplants
and plants grown from seeds collected in natural
populations; breeding studies; physiological and phenological
investigations; cytological studies; ecological
studies...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
Purpose: The purpose of this investigation was to identify a deep-water running (DWR) style that most closely approximates terrestrial running. Methods: Twenty healthy male and female intercollegiate (NCAA III) distance runners were videotaped from the right sagittal view while running on a treadmill (TR) and in deep water at 55-60%...
Forest management requires classification of forest stands into groupings or types based on structural similarities, even when structure varies continuously along gradients. Managed, mixed-species, multi-aged forest stands often display complex structures containing extreme variation in trees size, density, and species composition, and as a result have diverse canopy structures. A...
Biological studies were conducted on a histozoic myxosporidan
Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of
Oncorhynchus tshawytscha (Walbaum). This organism is known to
occur in spring chinook salmon in Oregon and coho salmon O. kisutch
(Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake
and Wood, 1957) was...
Caurinus dectes Russell is a minute, brachypterous scorpionfly
which was discovered at Marys Peak, Benton County, Oregon, in
1976, and subsequently described as the only representative of the
subfamily Caurininae within the Boreidae (snow scorpionflies).
Caurinus dectes is now known to range from the Olympic Peninsula
and Northern Cascades in...
This thesis research consists of an investigation of the human
influences on wildlife in Belize. The study was accomplished by the
collection and analysis of data with respect to land use, habitat
characteristics, and wildlife status in Belize. Requirements and
status of many species are tabulated in order to give...
