The extent of agricultural drainage has created concern for its potential undesirable effects on surface water quality. Land applications of liquid manure on tile drain fields have the potential to transport solutes and bacteria to the drains following precipitation or irrigation events and many times are directly sent to a...
This paper is an attempt to summarize our actual knowledge about the marine resources available in the area. It also analyzes the situation of the fishery and the principal aspects involved in a possible plan for an integral fisheries development of the Oceanic region around the islands. This plan could...
A field experiment under irrigation was conducted at the
Hyslop Agronomy Farm, near Corvallis, Oregon, during the 1967
growing season to evaluate the effect of barley row spacing, nitrogen
rate and placement, and weed competition in the year of seeding upon
birdsfoot trefoil (Lotus corniculatus L.) seedling establishment.
The effect...
This thesis is an offering, request, testimonio, refusal, and compliance to the discipline of anthropology and higher education. In this thesis, I engage with different forms of storytelling to highlight the relationships of mixed-status families in the United States. To accomplish this, I draw on the experiences of my mother...
To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...
Wave breaking in the surf zone is an important forcing
mechanism on the generation of nearshore currents and in the driving
of sediment transport. At the same time, wave breaking can have
significant spatial and temporal variability that needs to be
accounted for in the description of nearshore processes. Remote...
An analysis was conducted to estimate the minimum mesh
size for managing the common Chilean hake (Merluccius gayi)
fishery. Secondary objectives were to establish the
selective relationship between mesh size and fish length,
to examine growth patterns and related parameters, and to
estimate the critical age (or optimum size) at...
Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F

hybrid plants that were sterile. One parent genotype (P₁)
was from P. I. 234-906, introduced from Switzerland and the other
(P₉) was an introduction from Turkey, P. I. 174-209. P₁
and...
Ocean acidification disrupts marine and coastal ecosystems’ carbonate chemistry, directly and indirectly affecting communities that depend on critical marine organisms. Ocean acidification research typically seeks to understand natural system responses; yet there is insufficient research that examines community and institutional responses or, more generally, their vulnerability to ocean acidification. This...
