Fall directions and breakage of riparian trees along streams in the Pacific Northwest

Creator:: Sobota, Daniel J.
Abstract:: In the Pacific Northwest, regulatory agencies have recently implemented management strategies for restoration and maintenance of wood recruitment to streams over time. This allochthonous organic material is a critical component in the geomorphic and biological structure of forested streams. Mathematical models are commonly used to evaluate long-term wood dynamics in...

The ecology of wild turkey (Meleagris gallopavo) foraging in Pacific Northwest ecosystems

Creator:: Evans-Peters, Sara Tondee
Abstract:: Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Functional relationships among vegetation, nocturnal insects, and bats in riparian areas of the Oregon Coast Range

Creator:: Ober, Holly K.
Abstract:: Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...

Sandy beach surf zones : what is their role in the early life history of Chinook salmon (Oncorhynchus tshawytscha)?

Creator:: Marin Jarrin, Jose R.
Abstract:: Early life stages of many marine and diadromous fish species use sandy beach surf zones, which occur along >50% of the world's marine coastlines. This extensive habitat can provide juvenile fishes with an abundant supply of potential prey and the ability to hide from predators in its shallow turbid waters....

Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

Creator:: Buffington, Kevin J.
Abstract:: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

Seasonal influences on food availability and diet of coastal cutthroat trout in relation to riparian vegetation

Creator:: Romero, Nicolas
Abstract:: Current riparian management objectives in the Pacific Northwest promote both retention of existing conifers and conversion of hardwood-dominated areas to conifers. Although understanding of relationships between riparian vegetation and salmonid prey availability is growing, temporal variation in these relationships is poorly understood. Seasonal fluxes in availability of aquatic and terrestrial...

Arthropod prey for riparian associated birds in headwater forests of the Oregon Coast Range

Creator:: Hagar, Joan C., Li, Judith, Sobota, Janel, and Jenkins, Stephanie
Abstract:: Headwater riparian areas occupy a large proportion of the land base in Pacific Northwest forests, and thus are ecologically and economically important. Although a primary goal of management along small headwater streams is the protection of aquatic resources, streamside habitat also is important for many terrestrial wildlife species. However, mechanisms...

Impacts of agricultural drainwater and contaminants on wetlands at Kesterson Reservoir, California

Creator:: Schuler, Carol Ann, 1946-
Abstract:: Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than...

Stream habitat classification and restoration in the Blue Mountians of northeast Oregon

Creator:: Ebersole, Joseph Lamar
Abstract:: The restoration of rivers and streams should be based on a strong conceptual framework. Streams are developing systems. As such, streams exhibit temporal behaviors that change with changing stream environments. Underlying the dynamic development of streams is potential capacity. Streams express this capacity as an array of habitats over time...
