Creator:: Dyrness, C. T., Franklin, Jerry F., Moir, William H., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...

Abstract:: A total of 23 forest communities have been identified and characterized in a preliminary manner. Data used in formulating the classification had previously been collected on 300 reconnaissance plots located on the H. J. Andrews Forest and surrounding area. Vegetation classification was facilitated by similarity analysis and stand ordination procedures...

Creator:: Campbell, Alsie Gilbert, Franklin, Jerry F., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Sixteen understory plant communities in the riparian zones of small streams are identified and described. They range from pioneer communities on gravel and rock to well-developed shrub communities on flood plains and terraces. Several other vegetation types are discussed. Distribution of communities within the riparian zone is also discussed. A...

Abstract:: The executive program and operating syntax of the forest growth model SUCSIM IV are outlined in Section A. Lists of parameters, state variables and other quantities, and their values (if constant) are given in Section B. The remainder of the bulletin is devoted to the models used. The quantities given...

Abstract:: A steady-state model designed especially for analysis of gas exchange studies of terrestrial net photosynthesis is discussed. The model expresses net photosynthesis as a function of light, temperature, CO₂ concentration, stomatal resistance, and other factors. The parameters of the model are estimated from data by nonlinear least-squares. The data set...

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...

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,...
