Episodic Dissolution, Precipitation, and Slip along the Heart Mountain Detachment, Wyoming
The Heart Mountain allochthon is among the largest landslide masses in the rock record. The basal fault, the Heart Mountain detachment, is an archetype for the mechanical enigma of brittle fracture and subsequent frictional slip on low-angle faults, both of which appear to occur at ratios of shear stress to normal stress far below those predicted by laboratory experiments. The location of the d...
متن کاملForest structure and regeneration following a mountain pine beetle epidemic in southeastern Wyoming
Rocky Mountain forests are currently experiencing a bark beetle epidemic of unprecedented severity and extent. Forest regeneration following bark beetle outbreaks is driven by the survival and density of understory trees (advance regeneration). The composition and density of the advance regeneration may differ substantially from the pre-outbreak overstory and across environmental gradients. We ...
متن کاملNative perennial forb variation between mountain big sagebrush and Wyoming big sagebrush plant communities.
Big sagebrush (Artemisia tridentata Nutt.) occupies large portions of the western United States and provides valuable wildlife habitat. However, information is lacking quantifying differences in native perennial forb characteristics between mountain big sagebrush [A. tridentata spp. vaseyana (Rydb.) Beetle] and Wyoming big sagebrush [A. tridentata spp. wyomingensis (Beetle & A. Young) S.L. Wels...
متن کاملChanges in Egg Size and Clutch Size with Elevation in a Wyoming Population of Mountain Bluebirds
Few studies have examined how avian life-history traits vary within populations as elevation increases and climate becomes more severe. We compared egg and clutch sizes of Mountain Bluebirds (Sialia currucoides) nesting at two elevations (1500 m and 2500 m above sea level) in the Bighorn Mountains of Wyoming over two years. Eggs laid by females at the high-elevation site were, on average, signi...
متن کاملChange in Bacterial Populations Downstream in a Wyoming Mountain Drainage Basin
Ten bacteriological tests were utilized to monitor different bacterial populations found in water samples taken from streams draining high mountain rangeland. Livestock grazing and recreation constituted the major uses of the study area. Vegetation types were typical of those found in other sub-alpine and alpine zones in the central Rocky Mountains. Results show differences in counts of bacteri...
