OSTI ID:6027369
The necessity to determine general effects of perturbations in the arctic resulting from energy development is the impetus for this research which quantifies the patterns of water and nutrient flux from fellfield through tussock tundra into riparian plant communities. The evaluation of the effects of this mass flow on plant productivity is one of the objectives of the proposed research. The second major goal is to quantify the effects of changes of this water and nutrient flux resulting from slope perturbations, such as increased water flow, fertilizer application, blading and vehicle tracks. Demographic studies of fellfield, tussock tundra, and riparian vegetation and the dynamics of rodent activity in regard to nutrient transfer will broaden the understanding of the biology of a small watershed. Results of the integrated subprojects will be used to test the main hypotheses of this project which concern patterns of water and nutrient flux from slopes into the riparian vegetation as a results of slope perturbations. With the obtained information, nutrient and water flux routines of ARTUS will be expanded, and a specific slope and watershed model developed.
