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
Alicia M. Hines, Vanessa O. Ezenwa, Paul C. Cross, Jared D. Rogerson
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...
Where the buffalo roam: The role of history and genetics in the conservation of bison on U.S. federal lands

2007, Park Science (24) 22-29
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...

Modeling the biophysical impacts of global change in mountain biosphere reserves
H.K.M. Bugmann, F. Ewert Bjornsen, W. Haeberli, Antoine Guisan, Daniel B. Fagre, A. Kaab
2007, Mountain Research and Development (27) 66-77
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...

Second chance for the plains bison

2007, Biological Conservation (136) 175-184
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...
A simple solar radiation index for wildlife habitat studies
Kim A. Keating, Peter J. Gogan, John N. Vore, Lynn R. Irby
2007, Journal of Wildlife Management (71) 1344-1348
Solar radiation is a potentially important covariate in many wildlife habitat studies, but it is typically addressed only indirectly, using problematic surrogates like aspect or hillshade. We devised a simple solar radiation index (SRI) that combines readily available information about aspect, slope, and latitude. Our SRI is proportional to the...
The art and science of weed mapping

2007, Environmental Monitoring and Assessment (132) 235-252
Land managers need cost-effective and informative tools for non-native plant species management. Many local, state, and federal agencies adopted mapping systems designed to collect comparable data for the early detection and monitoring of non-native species. We compared mapping information to statistically rigorous, plot-based methods to better understand the benefits and...
Evaluating estimators for numbers of females with cubs-of-the-year in the Yellowstone grizzly bear population
S. Cherry, G.C. White, K.A. Keating, Mark A. Haroldson, Charles C. Schwartz
2007, Journal of Agricultural, Biological, and Environmental Statistics (12) 195-215
Current management of the grizzly bear (Ursus arctos) population in Yellowstone National Park and surrounding areas requires annual estimation of the number of adult female bears with cubs-of-the-year. We examined the performance of nine estimators of population size via simulation. Data were simulated using two methods for different combinations of...
Translocation and disease monitoring of wild laysan ducks
Michelle H. Reynolds, Thierry M. Work
2007, Endangered Species Bulletin (XXXII) 52-54
The Laysan duck (Anas laysanensis), also known as the Laysan teal because of its small size, is a critically endangered waterfowl species that once occurred widely across the Hawaiian Archipelago. For the past 150 years, however, it was restricted to a single population on Laysan, a 4-square-kilometer (1.5-square-mile) island with...
Distribution and grain-size partitioning of metals in bovfom sediments of an experimentally acidified Wisconsin lake
John F. Elder
2007, Water Resources Bulletin (30)
A study of concentrations and distribution of major and trace elements in surficial bottom sediments of Little Rock Lake in northern Wisconsin included examination of spatial variation and grain-size effects. No significant differences with respect to metal distribution in sediments were observed between the two basins of the lake, despite...

Frequency-duration analysis of dissolved-oxygen concentrations in two southwestern Wisconsin streams
Steven R. Greb, David J. Graczyk
2007, Water Resources Bulletin (31) 431-438
Historically, dissolved-oxygen (DO) data have been collected in the same manner as other water-quality constituents, typically at infrequent intervals as a grab sample or an instantaneous meter reading. Recent years have seen an increase in continuous water-quality monitoring with electronic dataloggers. This new technique requires new approaches in the statistical...

Zircon crystallization and recycling in the magma chamber of the rhyolitic Kos Plateau Tuff (Aegean arc)
O. Bachman, B. L. A. Charlier, J. B. Lowenstern
2007, Geology (35) 73-76
In contrast to most large-volume silicic magmas in continental arcs, which are thought to evolve as open systems with significant assimilation of preexisting crust, the Kos Plateau Tuff magma formed dominantly by crystal fractionation of mafic parents. Deposits from this ∼60 km3 pyroclastic eruption (the largest known in the Aegean arc)...
Suspended-sediment transport measurement
John R. Gray
2007, Book chapter, Encyclopedia of Water Science
Of the two operationally defined phases of fluvial-sediment transport – suspended load and bedload – collection of suspended-load data is the more common. This is a reflection of a number of factors including the general predominance of suspended load over bedload in mass transport and the greater difficulty and costs...
Vision for a worldwide fluvial-sediment information network
J. R. Gray, W. R. Osterkamp
2007, Conference Paper, Proceedings of the Tenth International Symposium on River Sedimentation, August 1-4, 2007, Moscow, Russia
The nations of the world suffer both from the deleterious effects of some natural and human-altered fluxes of fluvial sediment and a lack of consistent and reliable information on the temporal and spatial occurrence of fluvial sediments. Decades ago, this difficulty was unavoidable due to a lack of understanding of...
