The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...
A soil container 12 feet in diameter and 4 feet deep was constructed around the root ball of a 92-foot Douglas-fir tree in a naturally regenerated stand. The weighing mechanism, consisting of 550 feet of
2.5-inch butyl rubber tubing filled with water connected to a standpipe,
was placed under the...
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...
"During the four meetings of the consumer modeling committee, discussion centered on the formation of systems models and the
problems they will pose for researchers concerned with consumer populations. Two coarse models were developed from these discussions, a compartment model (Figure 1) and a process model (Figure 2). The
compartments...
