In an experimental field study, populations of gray-tailed voles (Microtus canicaudus) were exposed to a commercial formulation of vinclozolin, a fungicide effective for disease control on ornamental plants, turf grasses, and fruits and vegetables. Vinclozolin has been shown in laboratory experiments to behave as an androgen antagonist, impairing the reproductive...
To assess the impact of low-altitude jet overflights on parental care, we examined nest attendance, time-activity budgets, and provisioning rates of 21 Peregrine Falcon (Falco peregrinus) pairs breeding along the Tanana River, Alaska in 1995 and 1996. Several intrinsic and extrinsic factors influenced attributes of nesting behavior. Female nest attendance...
The objective of this research was to improve our understanding of how
changes in the environment affect ecological processes. Change detection is often
confounded by the large variation found in ecological data due to the difficulty of
finding replicates in nature. Intertidal communities were chosen for studies of biophysical
We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and
monitored their movements to determine daily, seasonal, and sexual differences in
behavior and home range attributes. We also collected information on nest attributes,
survival, and dispersal of the radiocollared voles. Individual voles were monitored for
Significant use of cold in-place recycling (CIR) has occurred in
Oregon since 1984 as an alternative to other rehabilitation techniques
or to the reconstruction of distressed asphalt concrete (AC) pavements.
Due to the initial success of the projects cold recycled during 1984-85,
the Oregon Department of Transportation (ODOT) and Oregon...
The Whale Cove Site, 35LNC60, is a shell midden, showing
occupations from 3010 B.P. to 330 B.P., spanning the Early and Late
Littoral Periods. Analysis of mammalian faunal remains, bone and
antler tools, lithics and discriptions of recovered shellfish
artifacts allows for chronological refinement of the previously
mentioned archeologically defined...
Statistical analyses were used to develop predictive
models of rice blast and to relate the favorability of
environment to disease incidence and severity on different
rice cultivars at five sites in Asia. The WINDOW PANE
program was used to search for weather factors highly
correlated with blast. Stepwise and r-square...
The purpose of this study was to investigate the relationship of family size, birth order,
socioeconomic status, and parent-child relationships to young children's intellectual
Seventy-four children, 39 boys and 35 girls, with a mean age of 4 years-8 months,
and their parents (mothers and fathers), selected from 9 preschool...
Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of
ecological understanding. This work is my attempt at communicating both of these, in relation
to three questions about our understanding of the structure and dynamics of biological diversity.
These questions focus on a) advancing our understanding of...
Pinot noir has a reputation for lower color stability than other red wine varieties. Because it has relatively low anthocyanin and phenolic content and lacks acylated anthocyanin pigments compared to other red vinifera varieties, color extraction and stability are particularly important. Varying the processing during fermentation of red wine can...
