The goal of this research was (1) to identify the patterns or pattern pieces of
development for heterosexual, dyadic, romantic relationships that emerge from
mixed-sex, friendship groups and (2) to compare and contrast those patterns or
pattern pieces to patterns in existing stage theories. To address these goals, data
were...
This article examines relationships between hunter specialization and activity substitutability. Data were obtained from a mail survey of 6,983 deer hunters in eight states and 2,584 elk hunters in three states. Activity substitutability was measured by asking what activity would provide the same satisfaction as deer or elk hunting. Between...
Mefenoxam and fosetyl-Al are common fungicides used to supplement
disease control of Pythium damping-off and root rot in forest nurseries
of the western United States. However, it is unknown whether fungicide-resistant Pythium isolates are present or whether new fungicide
and biological treatments might also provide supplemental disease
control. Isolates of...
More than 40 years have passed since Shafer (1969) challenged the existence of the “average
camper.” Recognizing that participants in recreation activities are heterogeneous in their
commitments and interests, researchers have emphasized the importance of differentiating
users into meaningful homogeneous subgroups. In his seminal article, Bryan (1977) coined
the concept...
Meadowfoam (Limnanthes alba) is a commercial oilseed annual crop
grown in Oregon. After extracting oil from seed, the remaining seed
meal is rich in the secondary plant metabolite glucolimnanthin, which
can be converted into pesticidal compounds such as 3-methoxybenzyl
isothiocyanate (ITC) and 3-methoxyphenylacetonitrile (nitrile) in the
presence of the enzyme...
Fire-history reconstructions are based on tree-ring records that span the last few centuries and charcoal data
from lake-sediment cores that extend back several thousand years. The two approaches have unique strengths and
weaknesses in their ability to depict past fire events and fire regimes, and most comparisons of these datasets...
Rebuilding of some U.S. West Coast rockfish (Sebastes spp.) stocks relies heavily on mandatory fishery discard, however the long-term condition of discarded fish experiencing capture-related barotrauma is unknown. We conducted two studies designed to evaluate delayed mortality, physical condition,and behavioral competency of yelloweye rockfish, Sebastes ruberrimus, experiencing barotrauma during capture...
Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these...
