Growth and carbon allocation of red alder seedlings grown over a density gradient

Creator:: Giordano, Peter A.
Abstract:: The amount and quality of competition among individuals in developing plant communities is an important factor determining community structure, composition and development. In perennial plant communities, this competition is reflected by shifts in carbon allocation among plant parts and can result in long-term structural differences between neighboring individuals. This study...

The effect of riparian buffer strips on salmonberry (Rubus spectabilis) community structure in alder stands of the Oregon Coast Range

Creator:: Froyd, Cynthia A.
Abstract:: Salmonberry community structure was examined in alder-dominated riparian buffer strips in the Oregon Coast Range. Salmonberry growing on slopes was found to respond differently, to both characteristics of the buffer strips and to environmental factors, than salmonberry growing on terraces. Salmonberry, as measured by total height, number of ramets or...

Interspecific competition in young Douglas-fir plantations of the Oregon coast range

Creator:: Wagner, Robert Gordon
Abstract:: Improving vegetation management decisions in Pacific Northwest forests requires a better understanding of the interactions between planted conifers and associated vegetation. A practical index of interspecific competition, and quantitative models predicting conifer performance from such an index are particularly needed. To meet this need, neighborhood models of interspecific competition were...

Early competitive interactions between red alder and salmonberry in the Oregon Coast Range

Creator:: Kelly, Linda Susan
Abstract:: General outcomes of this study show that early growth of planted red alder is often slowed in the presence of neighboring vegetation, and overwhelmingly by salmonberry, a common associate in disturbed Oregon Coast Range habitats. Additionally, young red alder plantations located in riparian areas may be highly susceptible to frost...

Animal damage, vegetative competition and growth of western hemlock seedlings in the Coast Range of Oregon

Creator:: Hyatt, Joan Marie
Abstract:: The growth of western hemlock during the first four years of seedling establishment was examined in a competitive environment in which seedlings were exposed to various types of animal damage and salmonberry and/or alder competition. The study utilized an existing Nelder/replacement series experiment which focused on the competitive effects among...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...

Experimental analysis of intra- and interspecific competitive interactions between cutthroat trout and sculpins in small streams

Creator:: Ramirez, Ben S.
Abstract:: In the Pacific Northwest ecoregion of North America, sculpins represent a major constituent of freshwater assemblages in coastal rivers. Based on their prevalence and abundance, sculpins are likely important ecologically, yet little is known of their interactions with co-occurring species, such as widely studied salmon and trout (salmonines). In this...

Plant and amphibian assemblages in zero-order basins in the Oregon Coast Range

Creator:: Sheridan, Chris D.
Abstract:: We have a poor understanding of the biotic communities in zero-order basins, drainages extending from ridgelines to the initiation of first-order streams. This study describes baseline plant and amphibian composition in unmanaged zero-order basins in the Oregon Coast Range. Specifically, I studied: i) the spatial distribution and diversity of species,...

The structure and dynamics of red alder communities in the central coast range of western Oregon

Creator:: Carlton, Gary C.
Abstract:: Red alder (Alnus rubra Bong.) is a fast-growing pioneer species that colonizes disturbed forest sites west of the Cascade Mountains in the Pacific Northwest. Streambottoms, toe slopes, and mass movement of surface soils have historically provided the scarification and soil moisture necessary for successful regeneration of red alder. During the...

Comparison of soil and vegetation map delineation shapes and areal correspondence

Creator:: Bilton, Janet
Abstract:: Map delineations of soil and vegetation for a 14,000 acre (5,800 hectare) site in the Oregon Coast Range were compared. Research objectives were to ascertain the types of information that could be extracted from delineation comparisons and to develop a methodology suited to this purpose. The latter objective was achieved...
