With little previous research on Astragalus peckii (Fabaceae), a state-listed
Threatened species in Oregon, I investigated three facets of its biology which are
integral to the conservation and management of the species. First, a four-year
demographic study of two large populations revealed increasing population growth at
one site (Chiloquin) and...
Esmond Creek is a tributary to the Siuslaw River located in the Oregon Coast Range. It is 18 km in length and drains a watershed area is 48.9 km². Average channel gradient of the study reach is 0.9%. In 1988 a landslide
occurred in the Esmond Creek watershed involving approximately...
The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...
Establishing an effective management of former open access fisheries can
increase resource rents from close to zero to numbers as high as several
hundred Mio $ p.a., as it has been the the case in Iceland's cod fishery.
Whenever the corresponding harvesting rights are given out free of charge
as...
Two TaqMan-based real-time One-Step RT-PCR assays were developed for the rapid and efficient detection
of Raspberry bushy dwarf virus (RBDV) and Raspberry leaf mottle virus (RLMV), two of the most common
raspberry viruses in North America and Europe. The primers and probes were designed from conserved
fragments of the polymerase...
In this report we present results of a sound propagation modeling study off the coast of Newport, OR. Preliminary acoustic experimental data was also collected by an underwater glider equipped with a hydrophone to measure sound levels in a short transect perpendicular to the coast and away from a sound...
