Vegetation and stem mapping of watershed 10, H. J. Andrews Experimental Forest

Creator:

Hawk, Glenn M., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Stem mapping of all trees greater than 15 cm dbh has been completed on the 10.24 hectare watershed (No. 10) at H. J. Andrews intensive study site. Using a 25 m grid system, mapping of vegetation into 7 plant communities and then into 4 habitat types has also been completed....

Sensitivity analysis as "propagation of error" and model validation

Creator:

Overton, W. Scott

Abstract:

Conclusion: The first part of this note deals with problems of propagation of error and the latter part with questions commonly identified as "model validation" questions. It is concluded that all validation questions can be resolved into two parts: (1) strategic aspects, involving logical and inferential structures and (2) tactical...

Annotated bibliography on the role of foliage-feeding insects in the forest ecosystem

Creator:

Strand, Mary Ann Sall, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

This bibliography, an apparently haphazard sampling of literature from many sources, grew out of a general project that was intended to elucidate the role of consumers in the forest system. The 124 articles briefly abstracted here are ones that give some insight into the role of foliage-feeding insects. The process...

Diurnal dimensional fluctuation in a Douglas-fir stem in response to tree water status and certain environmental factors

Creator:

Lassoie, J. P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Diurnal changes in stem circumference at the 1954 and 1963 internodes of a 22-year-old Douglas-fir were monitored using automated band dendrometers. Determinations of internal tree water potential and estimates of transpiration were used to characterize the water status of the tree. Environmental monitoring included the measurement of air temperature along...

A review of forest biomass accumulation

Creator:

Turner, John, Cole, Dale W., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

"This report presents a reference list of available studies on aboveground forest biomass, together with (1) methods of sampling and estimation and some of the problems and errors associated with each method (given as an aid to comparison of data), (2) some results obtained from the literature of field estimates...

Direct solar radiation on various slopes for 45 and 47.5 degrees north latitude

Creator:

Buffo, John, Fritschen, Leo, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Direct-beam solar radiation is presented in graphical and tabular form for hourly, daily, and yearly values for 7 slopes on 16 aspects at 45 and 47.5 degrees north latitude. Theoretical equations necessary for the calculations are given. Solar altitude and azimuth during the day and year are also presented for...

A mathematical and experimental model of the phosphorus cycle in Castle Lake, California

Creator:

Richey, Jeffrey Edward, 1946-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

A study of the phosphorus dynamics in castle Lake, California, is presented. The approach is (1) to identify the important phosphorus parameters, (2) to develop and apply methods measuring the parameters in the field and (3) to develop a computer model of the phosphorus cycle. This model will be used...

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,...

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...
