The specific objectives of the program are: (1) To understand the relative behavior of terrestrial and aquatic ecosystems in various environments in the biome. (2) To develop conceptual and computer simulation models that describe nutrient, carbon, and waterflows on a short-term basis (fewer than ten years) and which integrate research...
This report describes decomposition studies conducted in the H. J. Andrews
Forest, Oregon in 1973. Changes in weight loss and nutrient content of
leaves, cones, branches, and bark of Douglas-fir and leaves of big-leaf
maple, vine maple, Rhododendron, red alder, sword fern Oregon oak, and
Chinkapin were recorded in a...
The following report Introduces a documentation scheme for flow
oriented ecosystem models and shows its application to a carbon-water
model developed within the coniferous biome. This documentation scheme
has remained operative through revision of this model and expansion of
It to include nutrient flows. This model and subsequent versions are...
The food habits of yellow perch in Lake Washington were studied over a period
of nine months. Altogether, 549 yellow perch were examined for the stomach
contents. The food consisted mainly of cottids, mysid shrimp, and chironomid
pupae and larvae; the predominant food item being the mysid shrimp.
There was...
