Seismo-acoustic signals associated with degassing explosions recorded at Shishaldin Volcano, Alaska, 2003-2004
T. Petersen
2007, Bulletin of Volcanology (69) 527-536
In summer 2003, a Chaparral Model 2 microphone was deployed at Shishaldin Volcano, Aleutian Islands, Alaska. The pressure sensor was co-located with a short-period seismometer on the volcano’s north flank at a distance of 6.62 km from the active summit vent. The seismo-acoustic data exhibit a correlation between impulsive acoustic signals...
Precursory seismicity associated with frequent, large ice avalanches on Iliamna Volcano, Alaska, USA
Jacqueline Caplan-Auerbach, C. Huggel
2007, Journal of Glaciology (53) 128-140
Since 1994, at least six major (volume>106 m3) ice and rock avalanches have occurred on Iliamna volcano, Alaska, USA. Each of the avalanches was preceded by up to 2 hours of seismicity believed to represent the initial stages of failure. Each seismic sequence begins with a series of repeating earthquakes...
Eruption and deposition of the Fisher Tuff (Alaska)--Evidence for the evolution of pyroclastic flows
Alain Burgisser, J.E. Gardner, P. Stelling
2007, Journal of Geology (115) 417-435
Recognition that the Fisher Tuff (Unimak Island, Alaska) was deposited on the leeside of an ∼500–700‐m‐high mountain range (Tugamak Range) more than 10 km away from its source played a major role in defining pyroclastic flows as momentum‐driven currents. We reexamined the Fisher Tuff to evaluate whether deposition from expanded...
Glacier-volcano interactions in the north crater of Mt. Wrangell, Alaska
Carl Abston, Roman J. Motyka, Stephen McNutt, Martin Luthi, Martin Truffer
2007, Annals of Glaciology (45) 48-57
Glaciological and related observations from 1961 to 2005 at the summit of Mt Wrangell (62.008 N, 144.028W; 4317 m a.s.l.), a massive glacier-covered shield volcano in south-central Alaska, show marked changes that appear to have been initiated by the Great Alaska Earthquake (MW = 9.2) of 27 March 1964. The...
Directed blasts and blast-generated pyroclastic density currents: a comparison of the Bezymianny 1956, Mount St Helens 1980, and Soufrière Hills, Montserrat 1997 eruptions and deposits
Alexander Belousov, Barry Voight, Marina Belousova
2007, Bulletin of Volcanology (69) 701-740
We compare eruptive dynamics, effects and deposits of the Bezymianny 1956 (BZ), Mount St Helens 1980 (MSH), and Soufrière Hills volcano, Montserrat 1997 (SHV) eruptions, the key events of which included powerful directed blasts. Each blast subsequently generated a high-energy stratified pyroclastic density current (PDC) with a high speed at...

2007, Book
This e-book is the product of a second workshop that was funded and promoted by the United States Geological Survey to enhance cooperation between states for the management of chronic wasting disease (CWD). The first workshop addressed issues surrounding the statistical design and collection of surveillance data for CWD. The...

Monitoring alpine plants for climate change: The North American GLORIA Project
C. Millar, Daniel B. Fagre
2007, Mountain Views (1)
Alpine Environments Globally, alpine environments are hotspots of biodiversity, often harboring higher diversity of plant species than corresponding areas at lower elevations. These regions are also likely to experience more severe and rapid change in climate than lowlands under conditions of anthropogenic warming (Theurillat & Guisan 2001; Halloy & Mark 2003;...
Adapting to the reality of climate change at Glacier National Park, Montana, USA
Daniel B. Fagre
2007, Conference Paper, Proceedings of the first international conference on the impact of climate change: On high-mountain systems
The glaciers of Glacier National Park (GNP) are disappearing rapidly and likely will be gone by 2030. These alpine glaciers have been continuously present for approximately 7,000 years so their loss from GNP in another 25 years underscores the significance of current climate change. There are presently only 27 glaciers...

Hydrology and geomorphology of the Snake River in Grand Teton National Park
Nicholas C. Nelson, John C. Schmidt
2007, Report
The influence of significant tributaries that join the Snake River within 10 km of Jackson Lake Dam (JLD) mitigate some impacts resulting from nearly 100 years of flow regulation in Grand Teton National Park. I analyzed measured and estimated unregulated flow data for all segments of the study area by...

Effects of supplemental feeding on gastrointestinal parasite infection in Rocky Mountain Elk (Cervus elaphus): Preliminary observations

2007, Veterinary Parasitology (148) 350-355
The effects of management practices on the spread and impact of parasites and infectious diseases in wildlife and domestic animals are of increasing concern worldwide, particularly in cases where management of wild species can influence disease spill-over into domestic animals. In the Greater Yellowstone Ecosystem, USA, winter supplemental feeding of...

As an emblem of the Great Plains, American Indians, and wildlife conservation, the American bison (Bison bison) is one of the most visible and well-known of wildlife species in North America (fig. 1, above). Species of the genus Bison originally entered the continent via the Bering land bridge from...

Mountains and mountain societies provide a wide range of goods and services to humanity, but they are particularly sensitive to the effects of global environmental change. Thus, the definition of appropriate management regimes that maintain the multiple functions of mountain regions in a time of greatly changing climatic, economic, and...

LoCoH: Non-parameteric kernel methods for constructing home ranges and utilization distributions
Wayne M. Getz, Scott Fortmann-Roe, Paul C. Cross, Andrew J. Lyons, Sadie J. Ryan, Christopher C. Wilmers
2007, PLoS ONE (2)
Parametric kernel methods currently dominate the literature regarding the construction of animal home ranges (HRs) and utilization distributions (UDs). These methods frequently fail to capture the kinds of hard boundaries common to many natural systems. Recently a local convex hull (LoCoH) nonparametric kernel method, which generalizes the minimum convex polygon...

Before European settlement the plains bison (Bison bison bison) numbered in the tens of millions across most of the temperate region of North America. Within the span of a few decades during the mid- to late-1800s its numbers were reduced by hunting and other factors to a few hundred. The...
