Managing small-acreage horse farms in central and eastern Oregon

Creator:: Oregon State University. Extension Service, Stephenson, Garry Owen, Hannaway, D., Bohle, Mylen G., Brewer, Linda J., Hammond, Ellen, Parsons, Cory, Schreder, Pete, and Fery, Melissa
Abstract:: Some good goals for a well-managed, small-acreage horse farm are: • A productive pasture with plenty of grass and few weeds • Less dust during the dry season and less mud during the wet season • Healthy horses free of problems associated with dust, manure, mud, and toxic plants •...

Managing small-acreage horse farms : for green pastures, clean water, and healthy horses

Creator:: Oregon State University. Extension Service, Stephenson, Garry Owen, and Hannaway, D.
Abstract:: The goals for a well-managed small-acreage horse farm are: A productive pasture with plenty of grass and few weeds Almost no mud during the rainy season All nutrients (manure and stall waste) generated by the horses recycled to feed the pasture or removed from the farm and recycled Healthy horses...

The value of short run in-stream temperature forecasts : an application to salmonids in the Klamath and John Day Rivers

Creator:: Huang, Biao
Abstract:: Water temperature is an important measure of water quality, as well as a dominant factor affecting aquatic life within the stream environment. Elevated water temperatures can decrease the survival rate of fish in each life stage. Cold water species, such as salmonids, are particularly susceptible to elevated water temperatures. For...

Non-equilibrium ecosystem dynamics: management implications for Oregon

Creator:: Institute for Natural Resources
Abstract:: The project focuses on nonequilibrium ecosystem dynamics, a body of scientific research that characterizes and interprets ecosystem change. INR summarizes knowledge from this field, describes ways in which the current management framework may be inconsistent with scientific findings, and helps identify options for future management. This paper is designed to...

Genetic diversity in coastal cutthroat trout and Dolly Varden in Prince William Sound, Alaska

Creator:: Griswold, Kitty E.
Abstract:: Genetic diversity of two salmonid species, Dolly Varden (Salvelinus malma) and coastal cutthroat trout (Oncorhynchus clarki clarki) in Prince William Sound, Alaska were examined at multiple spatial scales with three molecular markers. Pleistocene glaciers covered what is now Prince William Sound 8,000- 12,000 years ago and both species colonized the...

Terrestrial amphibian distribution, habitat associations and downed wood temperature profiles in managed headwater forests with riparian buffers in the Oregon Coast Range

Creator:: Kluber, Matthew R.
Abstract:: Western forests have become increasingly fragmented landscapes dominated by young stands. Given that western Oregon forests largely consist of headwater systems, there is a need to better understand how headwater forest taxa and their habitats are impacted by forest management practices. Several amphibian species associated with forested headwater systems have...

New tools and approaches to uncertainty estimation in complex ecological models

Creator:: Brugnach, Marcela
Abstract:: This dissertation investigates the problem of uncertainty in complex ecological models. The term "complex" is used to convey both the common and scientific meanings. Increasingly, ecological models have become complex because they are more complicated; ecological models are generally multi-variate and multi-leveled in structure. Many ecological models are complex because...

Biodiversity in managed forests of western Oregon : species assemblages in leave islands, thinned, and unthinned forests

Creator:: Wessell, Stephanie J.
Abstract:: Both leave islands, or green tree retention clusters, and thinning prescriptions have been proposed as alternative silvicultural strategies designed to sustain the structural and biological diversity of managed forests. However, the relationship of the physical structure of leave islands and thinned forests to their associated microclimates, flora, and fauna remain...

Wavelet analysis : linking multi-scalar pattern detection to ecological monitoring

Creator:: Anthony, Jill Ada Marie
Abstract:: Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...

Regions to streams : spatial and temporal variation in stream occupancy patterns of coho salmon (Oncorhynchus kisutch) on the Oregon coast

Creator:: Flitcroft, Rebecca L.
Abstract:: Aquatic ecological investigation is expanding to encompass considerations of multiple scales across large landscapes. Much of the analysis included in this work focuses specifically on coho salmon (Oncorhynchus kisutch) in multiple subbasins on the Oregon coast. Coho salmon were chosen for an investigation of spatial scales, network connections, and life...
