Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:

Janisch, Jack E.

Abstract:

As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Growth responses of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) to defoliation

Creator:

Osman, Khalid Amir

Abstract:

The effect of defoliation intensity and season on Douglas-fir growth were studied in three replications in the Siuslaw National Forest during 1988-1990. Four intensities of defoliation were applied once in either spring or summer 1988. Stem diameter and canopy area were linearly inversely proportional to the level of defoliation. Defoliation...

Edge effects of clearcut harvesting on ground arthropod species composition and predator community structure in old-growth Douglas-fir forests

Creator:

Work, Timothy Theron

Abstract:

Edge effects resulting from forest fragmentation are likely to alter the distributions and interactions of resident species. I evaluated changes in species composition, species turnover, and relative abundance of ground arthropods across replicated transects extending from regenerating clearcuts into old-growth Douglas-fir forests. Arthropods were collected from 3-August to 14-September in...
