The main objective of this program is to determine the number of spring chinook annually caught by the sport fishery from the Willamette River below Oregon City and from Multnomah Channel. This information, when combined with the Clackamas River catch and calculated Willamette Falls and Clackamas River escapements, provides an...
In the past, fisheries and aquaculture researchers in Africa have been handicapped by poor access to current scientific literature and difficulties in getting published in visible outlets. Efforts in the past decade to improve access, awareness and use of information have flourished. We examine whether these efforts are reflected in...

Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...
A series of experiments was designed to investigate differential
flood-tolerance and the phenomenon of flood-induced stomatal closure
of several fruit tree species. The first two experiments were conducted
with potted plants submerged outdoors 5-10 cm above the soil line.
Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion
rate...
There is a lack of available information concerning availability,
usability and utilization of school-owned land in western Oregon,
southwestern Washington and northwestern California. It would be
helpful to know if land is available for agricultural use, how it is used,
and ways that it can be used to give experience...
A great concern about the effect of oxygen in Se samples has been solved by a purification method called the distillation-with-Al method. The electrical conductivity of liquid Se prepared by this purification method shows Arrehnius behavior with a single activation energy and positive thermopower within the experimental temperature range. This...
