Winter wolf predation in a multiple ungulate prey system, Gates of the Arctic National Park, Alaska Winter wolf predation in a multiple ungulate prey system, Gates of the Arctic National Park, Alaska
We investigated patterns of winter wolf predation, including prey selection, prey switching, kill rates, carcass utilization, and consumption rates for four wolf packs during three different study periods (March 1989, March 1990, and November 1990) in Gates of the Arctic National Park and Preserve, Alaska. Wolves killed predominantly caribou (165 caribou, seven moose, and five Dall sheep...

Wolf predation on caribou calves in Denali National Park, Alaska Wolf predation on caribou calves in Denali National Park, Alaska
During 1987-1991, 29 to 45 radio-collared caribou cows were monitored daily during calving each year and their calves were radio-collared (n = 147 calves) to investigate calf production and survival. We determined characteristics of wolf predation on caribou calves and, utilizing information from a companion wolf study, evaluated the role of spacing by caribou cows in minimizing wolf...

Strontium isotope geochemistry of soil and playa deposits near Yucca Mountain, Nevada Strontium isotope geochemistry of soil and playa deposits near Yucca Mountain, Nevada
The isotopic composition of strontium contained in the carbonate fractions of soils provides an excellent tracer which can be used to test models for their origin. This paper reports data on surface coatings and cements, eolian sediments, playas and alluvial fan soils which help to constrain a model for formation of the extensive calcretes and fault infillings in the Yucca Mountain...
