Light and the behavior of pelagic animals during night and crepuscular periods

Creator:: Wisdom, Daniel W.
Abstract:: Light plays an important role in ecological processes in the ocean both day and night. While relatively inexpensive, off the shelf instruments are available to measure Photosynthetically Active Radiation or PAR during the day, efforts to quantify light levels at night have proven more difficult. The goal of this work...

The response of animals to herbicide-induced habitat changes

Creator:: Borrecco, John Edward
Abstract:: 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...

A study of behavior in the deer mouse Peromyscus maniculatus rubidus Osgood during its 24-hour cycle of activity in a simulated natural habitat

Creator:: Laban, Cornelis
Abstract:: 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...

A study of the effects of exposure to air on the respiration of two intertidal snails

Creator:: Baker, Carol Dianne
Abstract:: 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...

Analysis of the benthic Cumacea and Gammaridean Amphipoda from the western Beaufort Sea

Creator:: Castillo Alarcon, Jorge Gonzalo
Abstract:: A multidisciplinary western Beaufort Sea Ecological Cruise (WEBSEC) was conducted from August 15 to September 20, 1971. During the cruise, one hundred ninety-nine 0.1 m² Smith-McIntyre grabs samples were taken at forty stations located on the continental shelf and slope of the western Beaufort Sea. The Gammaridean Amphipoda and Cumacea...

Distribution of benthic fishes on the continental shelf and slope of the Oregon coast

Creator:: Day, Donald Stewart
Abstract:: 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...

Numerical classification analysis of infaunal composition and distribution on two Oregon coast beaches

Creator:: Nunez Dupre, Jose D.
Abstract:: This investigation examined the community structure of two intertidal sedimentary environments on the Oregon coast in terms of species composition and vertical distribution. A coring device was used to obtain samples from two levels above MLLW in each beach on four occasions. Of the 54 taxa found, 46.2% were crustaceans,...
