With a growing emphasis on details of behavior comes an increasing
need for knowledge of natural behavior patterns. Studies
on the life history of Peromyscus maniculatus have long been available
in the literature. More recently, investigators have turned to
analyzing the behavior of some of the subspecies of P.m. in...
The 36 samples collected with a 22-foot semi-balloon shrimp
trawl at depths from 40 to 1,829 meters off the central coast of
Oregon between July 1961 and June 1962 provided preliminary data
on the distribution, species composition, and associations of benthic
fishes with respect to depth and sediment type.
Sixty-seven...
Callistoma costatum and Tegula funebralis, marine intertidal
snails from low and high littoral zones respectively, were exposed to
air for two, six and twelve hour periods, during which time their
oxygen consumption rates were measured. The animals were then
immersed in sea water and their respiration rates recorded for a...
Interest in the distribution of Clostridium botulinum type E
was heightened by the sudden outbreak of human botulism from
smoked whitefish chubs and canned tuna fish in 1963. The question
arose as to how widely the organism is distributed among fish
and shellfish in the Northwest and what potential hazard...
Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
The objectives of this investigation were to examine the changes in vegetation resulting from application of herbicides, and to study the effects of these vegetative changes on the abundance and composition of small-mammal populations, and on deer usage of treated and untreated plots. Three areas in western Oregon were selected...
