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...

Energy transfer in an autotrophic-based ecosystem : with special reference to effects of fertilizer nitrogen additions

Creator:: Speir, Jon A. and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Three aspects of lotic ecology have been analyzed utilizing data collected from totally autotrophic-based streams maintained by the Weyerhaeuser Company: energy transfer, effects of nitrogen addition, and simulation modeling. All three streams had very similar periphyton, grazer, collector, invertebrate predator, and vertebrate predator (fish) communities during the study period (1972-1974)....

Songbird populations of precommercially thinned and unthinned stands of ponderosa pine in east-central Washington

Creator:: Putnam, Betsy June
Abstract:: Populations of breeding birds and forest composition and structure were examined in preconimercially thinned and unthinned ponderosa pine (Pinus ponderosa Laws.) stands in east-central Washington. Stands were composed of predominantly ponderosa pine with a multi-aged structure made up of small even-aged clumps. Thinning reduced the density and foliage volume of...

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...
