An evaluation of the likelihood of successful implementation of the long term coral reef monitoring program on the Commonwealth of the Northern Mariana Islands

Creator:: Kylstra, Pam
Abstract:: Coral reef ecosystems are the oceanic equivalent of tropical rainforests, in terms of biodiversity. The estimated 1,037,000 square kilometers worldwide of reef provide habitat for over one million species of plants and animals (Hinrichsen, 1997). Coral reefs are important to the economy of coastal nations because of the fisheries and...

Protection of groundwater from nonpoint source pollution: will Oregon's 1989 legislation meet the challenge?

Creator:: Homer, Pamela E.
Abstract:: Nonpoint sources of pollution are being recognized nationwide as a significant threat to groundwater quality. In Oregon, groundwater supplies in several areas have been affected by contamination possibly caused by nonpoint sources associated with agricultural activities, on-site sewage disposal, and inadequate hazardous materials management in urban areas. State groundwater protection...

Vegetation changes in the Willamette River Greenway, Benton and Linn Counties, Oregon, 1972-1981

Creator:: Wickramaratne, Siri Nimal
Abstract:: The nature and extent of niparian vegetation change from 1972 to 1981 in the Willamette River Greenway in Benton and Linn Counties, Oregon was quantitatively investigated. The study was primarily by aerial imagery analysis and associated field verification. A classification of vegetation and land cover within the study area was...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

Ecology of Columbian black-tailed deer fawns in western Oregon

Creator:: Pamplin, Nathan P.
Abstract:: Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

Forest-meadow dynamics in the central western Oregon Cascades : topographic, biotic,and environmental change effects

Creator:: Rice, Janine M.
Abstract:: Montane meadows comprise a small area of the predominantly forested landscape of the Oregon Cascade Range. Tree encroachment in the last century in these areas has threatened a loss of biodiversity and habitat. Climate change in the coming century may accelerate tree encroachment into meadows, and exacerbate biodiversity loss. Multiple...

Basins at risk : conflict and cooperation over international freshwater resources

Creator:: Yoffe, Shira
Abstract:: In the policy literature and the popular press, the issues of water and conflict are being raised together with increasing frequency. Geographic, international relations, and environmental security theories speculate on the linkages between geographic features, natural resources, spatial relationships, and war or acute conflict. Little quantitative or global-scale research exists,...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...

The visualization of perspective systems and iconology in Dürer’s cartographic works : an in-depth analysis using multiple methodological approaches

Creator:: Wörz, Adèle Lorraine
Abstract:: This dissertation uses a new methodological approach for an in-depth analysis of three cartographic works. Studies within the discipline of the history of cartography have followed various methodologies throughout the past century. This dissertation argues that in order to come to a more complete understanding of how maps were produced...
