Creator:: Welch, E. B. (Eugene B.), Pederson, G. L., Stoll, Richard Kenneth, and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Zooplankton grazing rates and life history stage densities for secondary production estimates were determined in three lakes in the Cedar River watershed, Washington. Eight copepod species, seven cladoceran and nine rotifer species were identified in the three lakes. No one species of cladoceran or copepod occurred in all the lakes,...

Creator:: Welch, E. B. (Eugene B.), Pederson, G. L., Stoll, Richard Kenneth, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Grazing rates and density of the crustacean zooplankton were measured in Findley and Chester Morse Lakes and Lake Sammamish, Washington. Sample analysis is incomplete at reporting time, thus estimates of production from examination of life stage biomass changes was not possible. Maximum density of crustacean zooplankton was about 10/1 in...

Creator:: Spyridakis, Dimitri E., Welch, E. B. (Eugene B.), U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Aquatic mineral measurements and sediment characterization of the Cedar River basin lakes and streams reveals two largely distinct physical and chemical environments. Near the headwaters of the Cedar River Watershed the composition of lakes and streams reflect adjacent rocks but the effects of forest and agricultural practices and of processes...

Creator:: Welch, E. B. (Eugene B.), Hendrey, George R., Rock, C. A., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Lakes Findley, Chester Morse and Sammamish, Washington, are characterized by one major outburst of phytoplankton productivity and biomass (mainly diatoms) with usually no or low fall activity. Vernal outbursts were often delayed in some lakes and years probably by unfavorable climate (snow cover and cloudy rainy conditions). Mean spring-summer productivity...

Creator:: Welch, E. B. (Eugene B.), Hendrey, George R., Litt, Arni, Rock, C. A., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Lakes Findley, Chester Morse and Sammamish, Washington, are characterized by one major outburst of phytoplankton productivity and biomass (mainly diatoms) with usually no or low fall activity. Vernal outbursts were often delayed in the monomictic lakes by inadequate light because of unfavorable climate and/or a lack of thermal stratification. Strong...

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...

Creator:: Black, Hugh C., 1941-, Taber, Richard D., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: This volume results from an experiment in data retrieval. During the initial stage of the Coniferous Forest Biome the authors were asked to provide access to the literature on mammals as it pertained to the interests of the Biome investigation. One constraint was that the total number of entries should...

Abstract:: Research activities in the post-IBP phase of the Biome program prior to July 1975 were reported in Internal Report 162. Summaries of research and synthesis activities from July 1975 to August 1976 are presented here. The reports are arranged in the following order: Analysis of individual terrestrial ecosystems, which has...
