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...

Abstract:: During the summer of 1971, diurnal patterns of water status were monitored in Acer circinatum. Measurements of transpiration rate, internal moisture stress, and relative leaf resistance were used to characterize the water status of the tree. For the days examined, the diurnal and seasonal fluctuations of water status in relation...

Abstract:: Preliminary results of a comprehensive study of hydraulic fluctuations in Douglas-fir (Pseudotsuga menziesii) stems in response to plant water status and environment are presented. Diurnal changes in stem circumference near DBH of a dominant Douglas-fir were monitored using automated band dendrometers. Measurements of transpiration rate, internal moisture stress and stomata...

Abstract:: FLEX1 is a general model processor, patterned after Klir's General Sequential System Paradigm (Figure 1). Specifically, the processor is a discrete time flux oriented realization of the general paradigm and can process non-linear, non-stationary, environmentally controlled state variable system models with explicit memory. The current version is restricted to not...

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...

Creator:: Milne, David M., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Two major objectives were accomplished. 1. A summary of the work done during 1970-71 on a single species intra-specific competition model was written. 2. A multispecies predator-prey model, incorporating the competition mechanism of the single-species model, was developed almost to completion. The single species model is a computer program that...

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...
