Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

Plant communities and succession in Oregon coastal salt marshes

Creator:: Jefferson, Carol A.
Abstract:: The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon. Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...

Resident cutthroat trout in the central Coast Range of Oregon : logging effects, habitat associations, and sampling protocols

Creator:: Connolly, Patrick John, 1955-
Abstract:: Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

The role of herbivores and productivity on community structure of rocky shores of the Galapagos Islands, Ecuador

Creator:: Vinueza, Luis R.
Abstract:: Ecosystems are facing increasing threats from human related activities, such as overfishing, pollution, habitat destruction, species invasions, and diseases, among others. While oceanic islands provide natural laboratories to understand ecological and evolutionary process, they are also particularly vulnerable to these impacts, given their usual isolation from the mainland and the...

The Response and Effect of Emergent Coastal Vegetation to Sedimentation and the Distribution of Coastal Vegetation Communities along Environmental Gradients

Creator:: Lemein, Todd
Abstract:: Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...

The ecological consequences of the reduction of species diversity : experimental approaches

Creator:: Allison, Gary William
Abstract:: The influence of loss of diversity on community dynamics and ecosystem functioning has recently received considerable attention. Although study of biodiversity has a long history within ecology, empirical investigations exploring consequences of loss have been rare. Because many factors confound diversity comparisons, experimental manipulations of diversity offer the most direct...

Ocean shore protection policy and practices in Oregon : an evaluation of implementation success

Creator:: Good, James W.
Abstract:: Oregon's beaches were designated public recreation areas by the 1967 Beach Law. These beaches and adjacent shorelands experience erosion and other hazards due to winter storm waves, weathering, and geologic instability. Sea cliff recession threatens older development and inadequate construction setbacks create hazards for new buildings. The typical hazard response...

Livestock, deer and logging interactions in the lodgepole pine/pumice region of central Oregon

Creator:: Stuth, Jerry W.
Abstract:: The objectives of this study were to: 1) determine production of plant species and utilization by cattle, sheep and deer as related to plant communities and timber management practices and 2) evaluate the interaction of range use between cattle and deer and between sheep and deer as affected by site...
