Grizzly Bear Density in Glacier National Park, Montana
We present the first rigorous estimate of grizzly bear (Ursus arctos) population density and distribution in and around Glacier National Park (GNP), Montana, USA. We used genetic analysis to identify individual bears from hair samples collected via 2 concurrent sampling methods: 1) systematically distributed, baited, barbed-wire hair traps and 2) unbaited bear rub trees found along trails. We u...
متن کاملDecadal-scale climate drivers for glacial dynamics in Glacier National Park, Montana, USA
[1] Little Ice Age (14th–19th centuries A.D.) glacial maxima and 20th century retreat have been well documented in Glacier National Park, Montana, USA. However, the influence of regional and Pacific Basin driven climate variability on these events is poorly understood. We use tree-ring reconstructions of North Pacific surface temperature anomalies and summer drought as proxies for winter glacia...
متن کاملGIS-based Habitat Models for Bighorn Sheep Winter Range in Glacier National Park, Montana
I used logistic regression to construct bighorn sheep winter range habitat models for 2 study areas in Glacier National Park (GNP), Montana. During 2 winters, habitat use was described through systematic ground surveys supplemented with focal observations, lasting 1-3 days, of recognizable individual sheep. Available habitat was evaluated using 12 habitat parameters, each measured at a 30-by-30...
متن کاملEstimating organic carbon on avalanche paths in Glacier National Park, Montana
has been approved by the Examining Committee for the thesis requirement for the Master of Arts degree in Geography at the May 2014 graduation. ii " Far away in Montana, hidden from view by clustering mountain-peaks, lies an unmapped northwestern corner-the Crown of the Continent. The water from the crusted snowdrift which caps the peak of a lofty mountain there trickles into tiny rills, which h...
متن کاملSnow Avalanche Path Terrain and Vegetation, Glacier National Park, Montana Author(s):
Snow avalanche paths are major geomorphic features in the Rocky Mountains of Glacier National Park, Montana. They are the most common and geographically widespread form of mass-wasting in the central portion of the park. Field work and aerialphoto studies identified over 800 such paths in the study area. Other mass-wasting phenomena are also common. Snow avalanche path directions in the study a...
