The vascular system of Aplysia californica is a simple visceromotor system with three main arteries innervated by a small pool of identified neurons. I used this system to
study the functions of neuropeptide transmitters and their actions on neural and muscle tissues. A central finding of this study is that...
The data described in this report were collected in support of the program, Abyssal Boundary Current Studies, funded by the National Science Foundation.

Bats represent the second most diverse group of mammals inhabiting the western slopes of the Cascade Range in southern Washington and Oregon Coast Range. Bat populations may well be sensitive to changes in forest age, structure, or distribution, but their nocturnal habits and high mobility render the study of the...

A series of stereo photographs displays a range of residue loadings for cleancut units in three general forest types common to coastal Oregon forest lands: Douglas-fir--western hemlock (second-growth), western hemlock--Sitka spruce, and red alder. Postburn residue levels are also represented for the Douglas-fir--western hemlock, and red alder types. Information with...
The Direct/Delayed Response Project (DDRP) has been designed and implemented to estimate the number of lakes and streams that might become acidic in three regions due to current or altered levels of acidic deposition. As part of DDRP, 145 watersheds in the northeast US were mapped at 1:24,000 for soils,...

Wecoma cruise W8807A was conducted in late July and early August 1988 as part of the Coastal Transition Zone project. CTD observations were made over a standard grid in the coastal transition zone off northern California between 37°N and 39.5°N that was occupied repeatedly during June, July and August; this...
This paper presents equations developed to predict the height to live crown base of six species in the central western Willamette Valley of Oregon. Weighted nonlinear regression was used to fit a separate logistic equation for each species. The predictor variables are total tree height, crown competition factor in trees...
Environmental restrictions have induced many sawmills to seek alternatives to pentachlorophenol (penta) or similar chlorinated phenols to control fungal sapstains on green lumber. Five alternative preventives were evaluated against a traditional penta product (Permatox 101) on Douglas-fir, hem-fir, and pine lumber in an accelerated 6-week test on small specimens in...

The series of mountain pine beetle infestations existing on the Plains/Thompson Falls Ranger District, Lob National Forest, since 1971 continued into 1988. While some infestations are waning, others are increasing. The potential for beetle-caused mortality exists in threatened, but as yet uninfested stands. Management alternatives are discussed.
Dwarf mistletoe is a serious problem on the Flathead Indian Reservation. Since the early 197o's, a procedure called thinning-sanitation has been applied to lightly infested stands. Evaluation of this procedure indicated that average dwarf mistletoe infection levels now range from 7 to 50 percent in larch and Douglas-fir treated 10...
Treating styroblock containers in hot water (68°C) with a very dilute bleach and detergent solution effectively reduced populations of Fusarium and Cylindrocarpon spp., two potential root pathogens of containerized conifer seedlings. However, the treatment did not significantly reduce levels of Phoma (another potential pathogen) nor saprophytic Penicillium and Alternaria spp....

I studied abundance patterns and habitat use of eight cavitynesting bird species in the Coast Ranges of Western Oregon during the
spring and summer of 1985 and 1986. Three age classes of unmanaged Douglas-fir (Pseudotsuga menziesii) stands were selected for study:
young (40-80 yrs), mature (80-200 yrs), and old-growth (>200...
