Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

Untangling the complexity of nearshore ecosystems : examining issues of scaling and variability in benthic communities

Creator:: Schoch, G. Carl
Abstract:: 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 interactions...

Hydrology and delineation in four wetlands in the Oregon Cascades

Creator:: MacLeod, Norman A.
Abstract:: Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

Salmon and marine-derived nutrient effects on primary and secondary trophic levels

Creator:: Claeson, Shannon M.
Abstract:: The purpose of this study was to understand the influence of organic material and nutrients from spawning salmon and supplemented salmon carcasses on stream food webs. My study objectives were to examine 1) assimilation of salmon-derived nutrients (SDN) by producers and consumers in the food web, 2) epilithic biofilm productivity,...

Post-eruption recovery and secondary production of grazing insects in two streams near Mt. St. Helens

Creator:: Meyerhoff, Richard Dietrich
Abstract:: The eruption of Mt. St. Helens provided the opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...

Ecology of populations of Van Dyke's salamanders in the Cascade Range of Washington State

Creator:: McIntyre, Aimee P.
Abstract:: The Van Dyke's salamander (Plethodon vandyke,) is a rare species endemic to Washington State. It has been found in cool moist microhabitats along streams, splash zones of waterfalls, and headwater seeps. We explored the association of the Van Dyke's salamander with hydrologic condition, geomorphology, disturbance characteristics, and vegetation structure in...

Relationships between oceanographic factors and the distribution of juvenile coho salmon (Oncorhynchus kisutch) off Oregon and Washington, 1982-1983

Creator:: Chung, Alton W.
Abstract:: Juvenile coho salmon (101-400 mm) were sampled by purse seine off the Pacific Coast from Waatch Point, Washington to Four Mile Creek, Oregon, out to 30 mi offshore, during the months of May, June, and September in 1982 and 1983. Sea surface temperature, surface salinity, surface chlorophyll-a concentration, and Secchi...

Habitat associations of riparian beetles (Coleoptera) at Big Beaver Creek Research Natural Area, North Cascades National Park, Washington

Creator:: LaBonte, James R.
Abstract:: Beetle diversity and habitat associations of five prevalent riparian plant communities were examined along the lower reaches of Big Beaver Creek Research Natural Area, North Cascades National Park, Washington. These communities were defined by dominant tree species, and included Alder Swamps, Cedar-Hemlock Forests, Douglas-fir Forests, Gravel Bars, and Willow-Sedge Swamps....

Mid-Montane Wetland Plant Associations of the Malheur, Umatilla and Wallowa-Whitman National Forests

Creator:: Crowe, Elizabeth A. (Elizabeth Ann), 1963-, Clausnitzer, Rodrick R., and United States. Forest Service. Pacific Northwest Region
Abstract:: The objectives of this guide are to provide information to allow users to be able to identify potential natural vegetation types in wetlands (and transitional riparian areas) and to provide information pertinent to the use and management of these areas. An attempt has been made to describe the successional status...
