The investigation was conducted from January 1965 to March
1966. An intensive effort was made to obtain large numbers of animals,
as it is believed that unavailability of specimens has been the
limiting factor in the amount of research concerning this species.
Two hundred and sixty-nine animals were collected. They...
Purpose: The purpose of this study was to determine the effectiveness, if any, of ten weeks of motor psychophysics training on the
development of dynamic muscular strength (as measured by the bench
press and squat) in male college athletes and non-athletes.
Procedures: This study was conducted during the first (spring)...
Intraspecific life history attributes of growth, survival, and reproduction can vary in
response to changes in the physical environment. These changes can induce a cascading effect
across trophic levels. In marine systems, shifts in ocean conditions such as warm and cold phases
of ENSO can change primary production in benthic...
Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the
Pacific Coast of North America were the subject of a systematic
investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T.
& G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens
Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...
While there is a persistent inverse relationship between latitude and species diversity across many taxa and ecosystems, deviations from this norm offer an opportunity to understand the conditions that contribute to large-scale diversity patterns. Marine systems, in particular, provide such an opportunity, as marine diversity does not always follow a...
Space flight results in loss of mass and function in skeletal
muscle. Data from manned flights and animal biosatellites give
evidence of possible changes in neuromuscular interactions.
Components at the neuromuscular junction are a potential site of
action for this space-induced muscle atrophy. We examined the
nicotinic acetylcholine receptor population...
Mechanisms by which plant organs accumulate
photoassimilate are important in determining final sink size
and may involve invertase activity. Because strawberry
fruit are strong sinks for sugars, changes in invertase
levels during development and mechanisms of sugar uptake
within the fruit were examined.
Fruit from greenhouse-grown, day-neutral strawberries,
(Fragaria X...
The objectives of this research were to 1) evaluate the establishment and peak standing crop of Berber Orchardgrass (Dactylis glomerata var. "Berber"), Palestine Orchardgrass (Dactylis glomerata var. "Palestine"), and Sheep Fescue (Festuca ovina var. "Covar") ; 2) to assess establishment and production changes resulting from environmental gradients (elevation, slope, aspect,...
In the past decade, declines in amphibian populations have captured scientific and popular interest. The causes of the declines are likely to be complex and involve interactions between several environmental stressors. Using multifactorial experiments, I investigated the combined effects of several anthropogenic stressors on developing amphibians in Oregon, USA. In...
