Nitrogen transformations

Creator:: Taub, F. B. (Frieda B.), Palmer, Fred, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The feasibility and enumeration studies have led to the following conclusions: The nitrogen fixation studies should be done in 1973, using acetylene reduction technique with some verification by N15. The denitrification studies should be done with N15 technique. The decision to continue more enumeration sampling of nitrogen transforming bacteria should...

Nitrogen transformation

Creator:: Staley, James T., Taub, F. B. (Frieda B.), and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Nitrogen fixation rates were determined periodically by the acetylene reduction technique at three depths in each of the lakes. Fixation began in June in Lakes Washington and Sammamish and peaked during July and August. Chester Morse and Findley Lakes did not exhibit acetylene reduction activity until August and the rates...

Phosphorus cycling during the stratified period in Lake Sammamish

Creator:: Welch, E. B. (Eugene B.), Spyridakis, Dimitri E., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: A steady-state phosphorus cycle was determined for the stratified period May to November in Lake Sammamish, Washington. A steady-state. condition for this period is considered at this time since data on some important processes are only sufficient to estimate average values for the stratified period. Nevertheless, such a cycle is...

Geochemical equilibria and primary productivity in natural lakes

Creator:: Welch, E. B. (Eugene B.), Spyridakis, Dimitri E., Christman, R. F. (Russell F.), 1936-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...

Life-history strategies of rainbow trout (Oncorhynchus mykiss) across a volcanic disturbance gradient at Mount St. Helens, Washington

Creator:: Blackman, Tara Elizabeth
Abstract:: 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...

Estimates of biomass of detritus food chain

Creator:: Bissonnette, Pam, Taub, F. B. (Frieda B.), U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Macrobenthos populations of the IBP lakes were sampled during October and November of 1972. Analyses of the samples revealed dominance of chrinomids and oligochaetes in both littoral and profundal regions for at least this time of year. Due to sampling difficulties the oligochaete material was not used for chemical analyses....

An ecosystem service approach to inform reactive nitrogen management in the lower Yakima River Basin, Washington

Creator:: Crowell, Morgan
Abstract:: Spatially explicit ecosystem service valuation (ESV) allows for the identification of the location and magnitude of services provided by natural ecosystems to human activities along with a measure of their significance based upon economic valuation. While ESV has been used to provide new insight into land use management, few studies...
