Community ecology of invasions: direct and indirect effects of multiple invasive species on aquatic communities

Creator:: Preston, Daniel L. and Henderson, Jeremy S.
Abstract:: With many ecosystems now supporting multiple nonnative species from different trophic levels, it can be challenging to disentangle the net effects of invaders within a community context. Here, we combined wetland surveys with a mesocosm experiment to examine the individual and combined effects of nonnative fish predators and nonnative bullfrogs...

Extreme Precipitation Appears a Key Driver of Mercury Transport from the Watershed to Cottage Grove Reservoir, Oregon

Creator:: Curtis, Lawrence R., Morgans, Donna L., Thoms, Bryn, and Villenueve, Daniel
Abstract:: An abandoned cinnabar mining and roasting site is in the major sub-basin of the watershed for Cottage Grove Reservoir, Oregon. Average surface sediment total mercury concentration in the river draining this sub-basin (0.61±0.52 μg /g) was about ten-fold higher than three smaller tributaries to the reservoir. Total mercury in reservoir...

What drives interaction strengths in complex food webs? A test with feeding rates of a generalist stream predator

Creator:: Preston, Daniel L., Henderson, Jeremy S., Falke, Landon P., Segui, Leah M., Layden, Tamara J., and Novak, Mark
Abstract:: Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing community dynamics. Multiple factors have been linked to trophic interaction strength variation, including species densities, species traits, and abiotic factors. Yet most empirical tests of the relative roles of multiple mechanisms that drive...

Field guide to the forested plant associations of the Mt. Baker-Snoqualmie National Forest

Creator:: Henderson, Jan A., Lesher, Robin D., Peter, David H., and Shaw, David C.
Abstract:: A classification of forest vegetation is presented for the Mt. Baker-snoqualmie Forest. It is based on the potential National vegetation and uses the plant association as the basic unit. The classification is based on 2464 sample plots distributed across the Forest from 1979 to 1990. Of these 1963 were in...

Creator:: Henderson, Emilie B., Ohmann, Janet L., Gregory, Matthew J., Roberts, Heather M., and Zald, Harold
Abstract:: AIM: Landscape management and conservation planning require maps of vegetation composition and structure over large regions. Species distribution models (SDMs) are often used for individual species, but projects mapping multiple species are rarer. We compare maps of plant community composition assembled by stacking results from many SDMs with multivariate maps...

Management of Italian Ryegrass (Lolium perenne ssp. multiflorum) in Western Oregon with Preemergence Applications of Pyroxasulfone in Winter Wheat

Creator:: Hulting, Andrew G., Dauer, Joseph T., Hinds-Cook, Barbara, Curtis, Daniel, Koepke-Hill, Rebecca M., and Mallory-Smith, Carol
Abstract:: Management of Italian ryegrass in cereal-based cropping systems continues to be a major production constraint in areas of the U.S.A., including the soft white winter wheat producing regions of the Pacific Northwest. Pyroxasulfone is a soil-applied herbicide with the potential to control broadleaf and grass weed species, including grass weed...

Is there an Urban-Rural Divide in Stated Preferences for Protecting an Endangered Species? The Case of the Cook Inlet Beluga Whale

Creator:: Lew, Daniel
Abstract:: General population stated preference surveys are generally drawn from random samples that typically contain a large number of urban households relative to rural households due to the spatial distribution of populations. Given this, it is important to understand and assess whether differences in the preferences and values these two populations...
