I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...
Throughout the world, weather-related and other natural phenomena claim thousands of lives and devour billions of dollars annually in recovery efforts. Destruction of life and property in the wake of disasters is devastating, and can have a dramatic impact on families and businesses around the globe. Yet, published works specifically...
Among sensory and food scientists, the 9-point hedonic scale has been the most
commonly used scale for measuring liking and disliking of products. Recently, the
Labeled Hedonic Scale (LHS) was developed to overcome some recognized limitations
of the 9-point hedonic scale. One of the claimed advantages of the LHS is...
This essay examines the low-income weatherization program in rural Oregon, shedding light on difficulties in increasing weatherization services to low-income rural households. This essay also identifies policy limitations. There are strict rules in place for utilizing Department of Energy weatherization funding and some of these rules
are likely to make...
The objective of this study was to compare two techniques for estimating benthic fluxes of nutrients (nitrate, phosphate, and silicic acid) and Ge/Si flux ratios. In situ flux chambers were deployed, and cores were collected and incubated at 9 sites along the California margin in July 2001. Both techniques were...
Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention
into the next century and are of major societal relevance. An important unknown among these interrelated processes is the role played by methane gas hydrates, at and below the...
A massive release of methane on the Cascadia Hydrate Ridge was documented
during a ROPOS program in August 1998, consistent with previously reported
observations in 1996. An extensive survey of the seafloor revealed that the
seeps lie within a narrow band trending 109 degrees. This feature parallels larger
mounds imaged...
Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...
Invasive plants have the potential to reduce the diversity of species in plant and animal communities. I examined the negative effect of two invasive wetland plants, purple loosestrife and reed canary grass, on the species richness and diversity of plant and moth communities within 24 wetland study sites in the...
