Comparisons of fish assemblages and habitat associations in littoral zones of reservoirs in the Willamette Basin, Oregon

Creator:: Bennett, Paul Michael
Abstract:: The littoral zones of seven reservoirs in the southern Willamette Valley of Oregon were sampled with a boat electroshocker during the summer months of 1995 and 1996. Shoreline substrates were inventoried before sampling sites were randomly selected. Sampling sites consisted of 9 of 12 possible habitat types including four substrate...

Wavelet analysis : linking multi-scalar pattern detection to ecological monitoring

Creator:: Anthony, Jill Ada Marie
Abstract:: Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...

The ecological and cultural importance of a species at risk of extinction, Pacific lamprey

Creator:: Close, David A., Fitzpatrick, Martin S., and Li, Hiram W.
Abstract:: The cultural and ecological values of Pacific lamprey (Lampetra tridentata) have not been understood by Euro-Americans and thus their great decline has almost gone unnoticed except by Native Americans, who elevated the issue and initiated research to restore its populations, at least in the Columbia Basin. They regard Pacific lamprey...

The Eco-hydrology of Tropical Peatlands Associated with Land Cover Changes

Creator:: Kurnianto, Sofyan
Abstract:: Tropical peatlands play an important role in global climate system by storing an immense of carbon that had been accumulated over thousands of years. Peatlands provide another important ecosystem service by regulating the hydrology. It is believed that peatlands act like a giant sponge by absorbing substantial amounts of water...

Benthic biological invasions in two temperate estuaries and their effects on trophic relations of native fish and community stability

Creator:: Castillo, Gonzalo C.
Abstract:: The extent of biological invasions, their role on the feeding of native fishes and their impact on community stability were investigated in Alsea Bay and Yaquina Bay, two estuaries on the central Oregon coast, USA. Most nonindigenous species (NIS) introduced in these intermediately invaded estuaries are considered byproducts of culturing...

Assessing population-level variation in the mitochondrial genome of Euphausia superba using 454 next-generation sequencing

Creator:: Johansson, Mattias, Duda, Elizabeth, Sremba, Angela L., Banks, Michael, and Peterson, William
Abstract:: The Antarctic krill (Euphausia superba Dana 1852) is widely distributed throughout the southern ocean, where it provides a key link between primary producers and upper trophic levels and supports a major commercial fishery. Despite its ecological and commercial importance, genetic population structure of the Antarctic kill remains poorly described. In...

Beyond the Benthos: The effects of stream restoration on habitat complexity and aquatic and riparian macroinvertebrate assemblages

Creator:: Lotz, Kelsey L.
Abstract:: Aquatic and riparian systems in the western United States have been highly modified by anthropogenic impacts since Euro-American settlement. Ecological restoration is a practice that has been widely conducted around the world to mitigate the degradation of these systems. The majority of stream restoration efforts have focused on improving in-stream...

Passive acoustic monitoring of owls: two studies in forested landscapes of the Pacific Northwest

Creator:: Duchac, Leila S.
Abstract:: Nearly all birds communicate through sound, and there has been much study of avian populations and communities using song and other vocalizations. Owls are no exception as they defend territories, advertise for mates, and defend against threats using various vocalizations. However, due to their generally nocturnal habits, some owl species...
