Craterellus tubaeformis is a small to medium-sized forest mushroom that is fairly common in the Douglas-fir/western hemlock forests of the Pacific Northwestern United States and is most often associated with decayed coarse woody debris. In this study, the mycorrhizae of Craterellus tubaeformis in western Oregon is identified by DNA analysis...
The commercial Dungeness crab (Cancer magister) fishery is Oregon’s largest trap-based fishery. Each year, crab vessels discard millions of pounds of bait, including squid, razor clams, and sardines, into the near-coastal ocean. Although the fishery season typically runs from December 1st through August 14th, most landings occur within the first...
We have developed simple and fun “fishing games” which can be played easily and quickly with cheap supplies—and which demonstrate important economic characteristics of fisheries. Players “fish” by scooping beads from a common bowl into individual cups placed near the bowl. The beads are the fish stock; the scoops are...
This circular describes research activities of the Oregon State College School of Engineering during the school years 1958-59 and 1959-60. These activities are listed according to the engineering department in which the research is carried out. In each department section are described facilities of the department, research projects, and graduate...
The desire to understand the spatial and temporal drivers of animal behavior and distribution relative to scale is central to movement ecology. Optimal foraging theory states that a predator should continue exploiting a patch until it is no longer profitable to do so. As human developments increasingly encroach on the...
Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...
