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...
The preliminary results of a study of the insect emergence at Findley Lake in the Cascade Mountains of Washington during 1972 are presented. Bottom samples were taken from different regions of the lake to compare
the insect emergence at the surface, the physical conditions of the bottom,
and the biological...
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...
Two econometric models were developed to forecast consumption,
production, and price of hardwood lumber, and removals and price
of hardwood sawlog stumpage. Four eastern U.S. regions were represented
in the models. Hardwood lumber consumption by manufacturing,
shipping, residential construction, and nonresidential construction
industries was recognized. Hardwood sawlog stumpage removals from...
A method of measuring the dehydrogenase activity of sediments at lOC was
calibrated by direct microcalorimetry at the same temperature. Field
measurements of dehydrogenase activity of sediments in Lake Washington
were converted to rates of metabolic heat release by means of the significant
regression of dehydrogenase activity on metabolic heat...
This annotated bibliography contains 392 published and unpublished
references that pertain to the natural resources in the Lake Washington
watershed, with particular emphasis on the aquatic environment. All
references are indexed by keywords.
Macroinvertebrates were sampled on a regular basis from March to October
1973. A relationship between chironomid length and biomass was established.
Production equations to be used for these insects are reported. A similar
length/weight relationship is presently being explored for the oligochaetes.
A proposal is made for calculating their production...
