Soils of the Oregon coastal fog belt in relation to the proposed "Andisol" order

Creator:: Badayos, Rodrigo Briones
Abstract:: A study was conducted to evaluate the properties of soils in the fog belt area of the Oregon Coast Range. Soils in the study were chosen to include only those belonging to Andepts or to andic subgroups. Samples were collected from eleven sites that were formed mostly from colluvial deposits...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Witmer, Gary William
Abstract:: Daily and seasonal habitat use by Roosevelt elk was investigated in the Oregon Coast Range on managed, public forestland. Over 3,700 locations of 6 radio-collared cow elk were recorded during 12 consecutive months. Two elk formed part of a north band and 4 elk were part of a south band....

The fate of organic and inorganic nitrogen inputs in an old-growth forest of the central Oregon Cascade Range

Creator:: Holub, Scott M.
Abstract:: Forests in the Pacific Northwest receive very little nitrogen through atmospheric deposition and thus studying the nitrogen cycle in this region can provide insights into how the unpolluted nitrogen cycle functions. I examined the fate of organic nitrogen versus inorganic nitrogen and the effect of tamlins on N retention by...

Calcium-oxalate in sites of contrasting nutrient status in the Coast Range of Oregon

Creator:: Dauer, Jenny M.
Abstract:: Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...

A chorological analysis of the grass balds in the Oregon Coast Range

Creator:: Aldrich, Frank T.
Abstract:: Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

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...

The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:: Boyle, Stephanie A.
Abstract:: The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

Habitat associations of small mammals and amphibians in the central Oregon Coast Range

Creator:: Martin, Karl J.
Abstract:: One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective was to identify, habitat associations of forest floor vertebrates at the...

Relationship between landscape structure and avian abundance patterns in the Oregon Coast Range

Creator:: McGarigal, Kevin
Abstract:: Human-induced fragmentation of forests is increasing, yet the consequences of these landscape changes to vertebrate communities are poorly understood. Despite progress in our understanding of how bird communities respond to forest fragmentation caused by agricultural or urban development, we have little understanding of these dynamics in landscapes undergoing intensive forest...
