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....

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...

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...

Creator:: Gay, Lloyd Wesley, 1933-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: This review concentrates on 10 recent publications dealing with various aspects of radiation exchange in forest vegetation. The articles are discussed with respect to the following categories: definitions, instrumentation, the modification of radiation by vegetation, and radiation budgets. The papers reviewed have appeared for the most part during the period...

Creator:: Turner, John, Dice, Steven Farnham, 1938-, Cole, Dale W., Gessel, Stanley P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Variation in nutrient content of forest trees is discussed using the data from literature plus data collected by the authors. Sections are included on sampling and methods of expression of nutrient content. The emphasis is on possible causes of variation, which involves nutrient variation between years, within the year, and...

Creator:: Pamatmat, Mario Macalalag, Bhagwat, Ashok M., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: A method of measuring the dehydrogenase activity of sediments at lOC was calibrated by direct microcalorimetry at the same temperature. Field measurements of dehydrogenase activity of sediments in Lake Washington were converted to rates of metabolic heat release by means of the significant regression of dehydrogenase activity on metabolic heat...

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...

Creator:: Rhoades, Frederick Mast, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: The fleshy carpophores of fungi fruiling, on soil and litter were collected from watersheds 2, 3, and 10, IBP sites located in the H.J. Andrews Experimental Forest near Blue River, Oregon (122° W, 44° N). No effort was made to systematize collections: all carpophores in fresh condition seen were taken....
