The feeding habits of the lanternfishes Tarletonbeania crenularis, Diaphus theta and Stenobrachius leucopsarus were studied by analyzing 1,735 stomachs from 54 collections from the slope waters off Newport, Oregon. Forty-one taxa of food items were identified. Euphausiids
(Euphausia pacifica), copepods (Calanus spp. and Metridia lucens) and amphipods (Parathemisto pacifica) were...
During the GEOSECS cruise of the R/V KNORR, July 1972-April 1973, a very complete and high quality nutrient data set was acquired for the Atlantic Ocean. One hundred and twenty-one hydrographic
stations were occupied throughout the Atlantic providing an
internally consistent picture of the nutrient dynamics for this ocean.
The...
Ultrastructural analysis and chemical inhibition studies were
carried out on first cleavage of Mytilus zygotes to determine possible
relationships between the mitotic apparatus and the cortex during
polar lobe formation.
The stages of mitosis correlated with the appearance of the
polar lobe were first determined by light microscopy. The polar...
Marine geophysical data from the continental margin of Baja
California and the Gulf of California, and geological and geophysical
data from the Baja California Peninsula and mainland Mexico, outline
the major geologic and tectonic features of the Baja California
Peninsula and the surrounding areas from 24.5° N. Lat. to 27.5°...
Seven socioeconomic factors common to two Oregon
communities, Beaverton and Corvallis, were examined and
compared for the influences they might have on participation
in recycling programs. Sampling technique involved
the use of a prepared survey questionnaire through which
the data necessary for the appropriate statistical methodology
used in the study...
This research paper is an analysis of the electric energy industry
in Mexico since its inception in 1879. The research is based entirely
on library sources plus documents secured from the Federal Electricity
Commission of Mexico. Only minimal documentary evidence is
available in English, consequently the Oregon State University library...
Joseph Reddeford Walker conducted
a party of men across the Sierra Nevada to the
Pacific coast of California in 1833. Previous
interpretations of the portion of the route
from Humboldt Sink, Nevada, to the San Joaquin
River, California, are not satisfactory. A
body of descriptions of the terrain traversed
exists...
To determine whether meiotic maturation of ovarian follicles,
ovulation, and oviposition are influenced by male mating behaviors,
female rough-skinned newts (Taricha granulosa) were captured prior
to contact with males and maintained in simulated pond conditions.
Females were either exposed to male courtship and inseminated or
were isolated from male contact....
The need for and problems related to string processing are
discussed and a definition of the term "string" is derived. A
brief review of some existing string processing systems leads
to the presentation of a design for a string processing extension
to the programming language Pascal. A rationale for the...
