Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well.
The overarching goal...
Limnology is undergoing a transition to high-throughput -omic analysis of freshwater
bacterial communities. An important first step in making the transition is to
characterize several genomes that can be used as references to guide metagenome
assembly and analysis. Here I characterize four new freshwater cyanobacterial
genomes, a pair of lake...
In this study, I examine the influence of habitat gradients created by the 1980 eruption of Mount St. Helens, Washington USA on a recently established Rainbow Trout (Oncorhynchus mykiss) population in the Spirit Lake basin. My goal was to evaluate the responses of fish in seven streams across a volcanic...
Concentration ratios are used to determine the transfer of nuclides from soil to biota to fauna. Some nuclides have limited associated data though, this has not prevented predictions from being performed at sites without associated data. These ratios are site specific and are not fully applicable when applied to other...
The long-toed salamander (Ambystoma macrodactylum)
is the top vertebrate predator in fishless high-elevation
lakes in North Cascades National Park Service Complex
(NOCA), Washington. The purpose of this research was to
determine the effects of physico-chemical factors and
introduced trout on abundance and behavior of A.
macrodactylum larvae. Although high-elevation lakes...
Factors affecting physical, chemical, and biological characteristics of lakes
were investigated through the development of a lake-classification system for 162
lakes in North Cascades National Park Service Complex. A conceptual view of lake
development and its relationship to the expression of lake and watershed
characteristics was derived. Water quality and...
Research on campsite selection behavior has given managers of outdoor recreation resources a better understanding of users' needs and preferences. However, researchers have found nagging inconsistencies, not only across settings but also between campers' stated preferences and their actual behavior. This thesis re-examines the campsite selection research in light of...
