The Eco-hydrology of Tropical Peatlands Associated with Land Cover Changes

Creator:: Kurnianto, Sofyan
Abstract:: Tropical peatlands play an important role in global climate system by storing an immense of carbon that had been accumulated over thousands of years. Peatlands provide another important ecosystem service by regulating the hydrology. It is believed that peatlands act like a giant sponge by absorbing substantial amounts of water...

The Influence of Scale in a Structured Decision Making Framework for Chinook Salmon Management

Creator:: McDonnell, Kevin N.
Abstract:: The goal of my dissertation was to explore how scale influences stream restoration prioritization strategies for an anadromous species and identify influential uncertainties that exist at different scales. My objectives were to (1) produce a comprehensive review of the Chinook salmon management challenges in California’s Central Valley and identify the...

Annual Costs of Wild Salmon Restoration Efforts in the Columbia River Basin

Creator:: Rice, Robert J.
Abstract:: The goal of this project was to estimate the total annual cost of salmon recovery efforts throughout the Columbia River Basin from all stakeholders, including direct and indirect costs. How much is spent on salmon recovery efforts each year in the Columbia River Basin? Depending on who you ask, you...

Spatial Variation in Ecosystem Carbon Stocks and Emissions Resulting from Land-use Conversion: Two Studies in Mangrove Forests of the Dominican Republic

Creator:: Giovannoni, Leila R.
Abstract:: Mangrove forests store more organic carbon across ecosystem carbon pools than most other coastal and forested ecosystems, and are subject to high global rates of deforestation. For these reasons, they are recognized as prime candidates for inclusion in climate change mitigation strategies. However, the ecological drivers of regional and micro-scale...

The relationship between the gut and the water-electrolyte balance of a marine teleost, Enophrys bison (Girard)

Creator:: Sleet, Randolph Bullock
Abstract:: In higher vertebrates, normal digestion and absorption by the gastrointestinal tract are dependent on the orderly and controlled transit of intraluminal contents. A relationship between fluid passage through the gut and absorption from the gut has yet to be examined in fish. In marine teleosts, the osmolality and ion concentration...

Public lands and private waters: scarce mesic resources structure land tenure and sage-grouse distributions

Creator:: Donnelly, J. P., Naugle, D. E., Hagen, C. A., and Maestas, J. D.
Abstract:: Water scarcity in semiarid environments provides a model system to evaluate the role of mesic resources in structuring the distribution and abundance of wildlife. We used remote sensing and point process analyses to evaluate spatio–temporal variability in limited mesic resources in relation to greater sage-grouse (Centrocercus urophasianus) distributions in Oregon,...

Effect of age-based and environment-based cues on reproductive investment in Gambusia affinis

Creator:: Billman, Eric J. and Belk, Mark C.
Abstract:: We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...

Effects of water withdrawals on macroinvertebrate emergence: Unexpected results for three holometabolous species

Creator:: Brown, P. D., Wooster, D., Johnson, S. L., and DeBano, S. J.
Abstract:: Small, low-head diversion dams are capable of withdrawing much of the flow of a river, often resulting in elevated water temperatures. Accelerated growth and development of aquatic invertebrates has been demonstrated in warmer temperatures, suggesting that the timing of insect emergence and adult body size may be significantly altered by...

Resource waves: phenological diversity enhances foraging opportunities for mobile consumers

Creator:: Armstrong, Jonathan B., Takimoto, Gaku, Schindler, Daniel E., Hayes, Matthew M., and Kauffman, Matthew J.
Abstract:: Time can be a limiting constraint for consumers, particularly when resource phenology mediates foraging opportunity. Though a large body of research has explored how resource phenology influences trophic interactions, this work has focused on the topics of trophic mismatch or predator swamping, which typically occur over short periods, at small...

Effects of Low-Density Feeding on Elk-Fetus Contact Rates on Wyoming Feedgrounds

Creator:: Creech, Tyler G., Cross, Paul C., Scurlock, Brandon M., Maichak, Eric J., Rogerson, Jared D., Henningsen, John C., and Creel, Scott
Abstract:: High seroprevalance for Brucella abortus among elk on Wyoming feedgrounds suggests that supplemental feeding may influence parasite transmission and disease dynamics by altering the rate at which elk contact infectious materials in their environment. We used proximity loggers and video cameras to estimate rates of elk-to-fetus contact (the primary source...
