The water and energy dynamics of an old-growth seasonal temperate rainforest

Creator:: Link, Timothy E.
Abstract:: In the Pacific Northwest (PNW), concern about the impacts of climate and land cover change on water resources, flood-generating processes, and ecosystem dynamics emphasize the need for a mechanistic understanding of the interactions between forest canopies and hydrological processes. A detailed measurement and modeling program during the 1999 and 2000...

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...

Ecological relationships between cervid herbivory and understory vegetation in old-growth Sitka spruce-western hemlock forests in western Washington

Creator:: Happe, Patricia Jenkins
Abstract:: The relationships between black-tailed deer (Odocoileus hemionus columbianus) and Roosevelt elk (Cervus elaphus roosevelti) herbivory and understory vegetation in unmanaged forests in Olympic National Park were studied from 1985 - 1989. From 1985 to 1986 I studied the impact of cervid exclusion on shrub, fern, and forb forage quality, tannin...

Microbial community structure as influenced by season and stand age in a Douglas-fir (Pseudotsuga menziesii) ecosystem

Creator:: Kucera, Jennifer Moore
Abstract:: Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...

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...

Diversity, productivity, and mycophagy of hypogeous mycorrhizal fungi in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley
Abstract:: Hypogeous fungi are a critical component of forest ecosystems world wide. In Pacific Northwest forests, they are the base of the food chain of the threatened Northern Spotted Owl. As part of The Forest Ecosystem Study (a interdisciplinary study designed to increase development of suitable spotted owl habitat), diversity and...

Patterns and dynamics of context-dependency in the marine rocky intertidal

Creator:: Berlow, Eric Layani
Abstract:: As ecologists are being called upon to predict the consequences of human perturbations to natural communities, an important goal is to understand what factors drive variability or consistency in nature. In the rocky intertidal of San Juan Island, Washington, a comparative experimental approach was used to investigate spatial and temporal...

A landscape-scale analysis of vegetation recovery at Mount St. Helens

Creator:: Lawrence, Rick L.
Abstract:: I used satellite remote sensing to examine the key factors controlling the natural revegetation of Mount St. Helens since its eruption in 1980. The study required three stages: determining the amount of vegetation present; characterizing vegetation change; and analyzing the influence of factors affecting vegetation change. To determine the amount...

Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

Creator:: Eskelson, Bianca N. I.
Abstract:: The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

Composition, distribution and succession of subalpine meadows in Mount Rainier National Park

Creator:: Henderson, Jan A.
Abstract:: In 1970 a phytosociological reconnaissance consisting of 135 plots in the Subalpine Meadow Zone was made. These samples were sorted using an association table and several Alpine Zone and very early seral communities were set aside, An additional hundred plots taken by M. J. Hamann were incorporated with these and...
