Meadow classification in the Willamette National Forest and conifer encroachment patterns in the Chucksney-Grasshopper meadow complex, Western Cascade Range, Oregon

Creator:: Dailey, Michele Meadows
Abstract:: This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...

A study of in stream complexity in three Oregon Coast Range watersheds

Creator:: Anderson, Paul Khalil
Abstract:: This study investigates patterns of physical structure organization in stream networks. In particular, it seeks to describe patterns of wood, boulders, pools and slope that are evident in stream channels and to determine whether patterns of these elements are influenced by network-level controls. The four in-stream parameters were combined to...

Spatial patterns of invasion by exotic plants in a forested landscape

Creator:: Parendes, Laurie Anne, 1958-
Abstract:: Few landscapes are immune to invasion by exotic plant species. The forested landscape in the western Cascade Range of Oregon appears to have some barriers to invasion, but the extensive road network provides a corridor and habitat for a suite of exotic species to enter and become established. This study...

Lacustrine micro-fossil assemblage in core NP04-KH3, a Kullenberg piston core from the Moba-Kalya Horst region of Lake Tanganyika, East Africa, as a biogeochemical proxy for Late Pleistocene and Early Holocene climate and lake level changes

Creator:: Steinkamp, Matthew J.
Abstract:: The objective of this research is to determine the correlation of lacustrine micro-fossils in Lake Tanganyika to changes in climate and lake levels during the Late Pleistocene and Early Holocene. Lake Tanganyika is the second deepest and one of the oldest lakes in the world. The horst and graben geometry...

The effects of ownership pattern on forest road networks in western Oregon

Creator:: Freid, Matthew A.
Abstract:: The pattern of ownership imposed on the-forest landscape of Western Oregon defines the boundaries in which differences in jurisdiction, regulation, and land use operate. Road building is controlled by these factors, and in turn has an effect on the cumulative effects of human utilization of the forest. This study examined...

The historic and contemporary ecology of western Cascade meadows : archeology, vegetation, and macromoth ecology

Creator:: Highland, Steven A.
Abstract:: Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...

A review and assessment of network concepts and their applications in geography and related disciplines

Creator:: Versluis, Anna J.
Abstract:: Networks are a structure common to many disciplines. Research on networks has taken different forms in domains such as graph theory, sociology, vascular networks, small-world networks, geomorphology, ecology, evolution and engineering. Networks may be modeled as non-spatial networks (unvalued graphs), which contain only topological information, or as spatial networks (valued...

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

A study of varying logging practices on stream temperature in the Blue River drainage, Western Oregon Cascades

Creator:: Nicolello, Jon
Abstract:: Three (3) streams with desired similar characteristics, located in the Blue River Watershed in the Central Oregon Cascades, were studied to better understand the impacts of forest harvest on stream temperature and aquatic habitat. Of the 3 designated streams, North Fork Quartz Creek, Blue River Face, and Wolf Mann, only...

Patterns of chronic wind mortality in a small, old-growth Pseudotsuga menziesii forest in the western Cascades, Oregon

Creator:: Littlefield, Sam, 1980-
Abstract:: Windthrow has been studied extensively as a cause of mortality and as a landscape disturbance agent in temperate forests throughout the United States. The effects of windthrow mortality on stand species composition and structure, forest regeneration and seral development have been well described at the site (e.g. single gap) and...
