Grazing and production by zooplankton in lakes of contrasting trophic status : a progress report

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...

Phytoplankton productivity and response to altered nutrient content in lakes of contrasting trophic state

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...

Benthic macroinvertebrate production

Creator:

Bissonnette, Pam, Taub, F. B. (Frieda B.), U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

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...

The physical matrix of Castle Lake

Creator:

Goldman, Charles Remington, 1930-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The physical framework or matrix in which the biological processes of aquatic ecosystems occur is currently under investigation at the Castle Lake Research Station. Special attention has been given these physical parameters in view of their close interrelationship with important biological properties within the lake (as exemplified by the rate...

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...

Grazing and production by zooplankton in lakes of the Cedar River watershed

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,...
