Understanding place as a cultural system: implications of theory and method
This dissertation seeks to provide insight into the relationships between public philosophy and the theoretical and methodological implications of social inquiry; to increase understanding of what it means to conceive of place as a cultural system; and to increase understanding of what it means to take a civic science approach ...
Habitat connectivity and spotted owl population dynamics
The ecological consequences of habitat fragmentation include the direct effects of habitat loss and the indirect effects of reduced inter-patch dispersal. I examine these consequences of habitat fragmentation through two separate studies. The first study measures habitat connectivity through the success of a simulated dispersal ...
Nitrogen and phosphorus availability, ecosystem processes and plant community dynamics in boreal wetland meadows
The effects of nitrogen (N) and phosphorus (P) availability on above-ground primary production and plant community dynamics in wetland "beaver" meadows were examined in Voyageurs National Park in northern Minnesota, USA. Five meadows were floristically distinguished as either "sedge-dominated" or "grass-dominated" and were ...
Wind stability of naturally regenerated and planted Douglas-fir stands in coastal Washington, Oregon, and British Columbia
Risk of wind damage is an important factor influencing forest management throughout the world. Managed forest landscapes of the coastal Pacific Northwest are undergoing a transition from dominance by naturally regenerated second-growth stands to Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) plantations. This analysis ...
