Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...
The Farm Enterprise Committee of the Confederated Tribes of
the Umatilla Indian Reservation requested that an evaluation be made
of the Reservation land resource for the purpose of acquisition by the
Tribe as a part of a study of the feasibility of an expanded farm
enterprise. The Committee's primary goal...
Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...
This study describes the soils, vegetation and age structure
of the Pinus contorta forests of Crater Lake National Park. Growth
rates of P. contorta, and levels of infection and impact of dwarf
mistletoe (Arceuthobium americanu1r) on growth of P. contorta
individuals are compared among communities.
Vegetation description is based on...
Clearcutting is a sound silvicultural practice when exercised
in the proper environmental location. Foresters have learned through
bitter experience that clearcutting Douglas-fir forests, located on
droughty south-facing slopes, often leaves uncorrectable regeneration
problems. Thousands of acres of unproductive grass and brush throughout
the Douglas-fir region are unavoidable reminders of inappropriate...
Eighty-one microbial species isolated from seafoods and other marine sources were examined to determine the extent of interactions among these species. Spot-plates, cross-plates, and concurrent growth experiments at 7, 15, 20, and 30 C indicated that Lactobacillus species were capable of inhibiting other microorganisms. Lactobacillus species isolated from oysters and...
