Holocene fire and vegetation along environmental gradients in the Northern Rocky Mountains
Holocene records of fire, vegetation, and climate were reconstructed from four sites in the Bitterroot Range region of the Northern Rocky Mountains in order to examine the vegetation and fire histories and evaluate the hypothesis proposed by Whitlock and Bartlein (1993) regarding the effects of increased summer insolation on precipitation patterns. Vegetation history in the series of sites was ...
متن کاملWolf-cattle Interactions in the Northern Rocky Mountains
Since gray wolf reintroduction in 1995, wolf populations in the northern Rocky Mountains have increased dramatically. Incidents of wolf predation on livestock have increased with wolf populations. Although rough tallies of livestock death or injury losses caused by wolf predation are made each year, we know almost nothing about the indirect effects of wolf-livestock interactions on cattle produ...
متن کاملPersistent organic pollutants in air and vegetation from the Canadian Rocky Mountains.
The exchange of chlorinated organic pollutants between air and vegetation in cold, mountain environments was investigated through the extraction of coniferous vegetation and high-volume air samples collected from the Canadian Rocky Mountains during the summers of 1999 and 2000. Concentrations of several compounds in vegetation increased as temperatures decreased, whereas atmospheric concentrati...
متن کاملLee-side Frontogenesis in the Rocky Mountains
The development and motion of fronts associated with lee-side troughs on large mountain barriers has been investigated. These fronts differ from ordinary cold fronts in their horizontal temperature field, which is characterized by a sinusoidal thermal ridge. The thermal ridge intensifies, while remaining stationary with respect to the mountains, and moves eastward upon the approach of a Pacific...
