Climate models differ in their responses to imposed forcings, such as increased greenhouse gas concentrations, due to different climate feedback strengths. Feedbacks in NCAR’s Community Atmospheric Model (CAM) are separated into two components: the change in climate components in response to an imposed forcing and the “radiative kernel,” the effect...
This is the fifth in a series of studies to evaluate perceptions of the roles, responsibilities,
and issues entailed in the jobs of U.S. Department of Agriculture Forest
Service law enforcement and investigations (LEI) personnel. An e-mail survey
was administered to the 537 Forest Service forest supervisors and district rangers...
One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....
Predation by piscivorous marine fishes has been hypothesized to be a primary source of marine
mortality for Pacific Northwest juvenile salmon. During the springs and summers of 1998–2004, we collected predator and prey fishes (forage and juvenile salmonids) at the surface at night off the mouth of the Columbia River....
In some homes, clothes moths can damage garments and other belongings. There are two common species of clothes moths in the Pacific Northwest: the webbing clothes moth (Tineola bisselliella) and the casemaking clothes moth (Tinea pellionella). The larvae,
or immature form, of the moths are responsible for the damage done...
When applying pesticides it is important to avoid water contamination and pesticide drift as much as possible. This checklist can help. Three separate checklists(before, during and after) make it easier to remember things to do before, during and after an application to avoid contamination and drift.
