2007, Journal of Volcanology and Geothermal Research (166) 177-192
During 2001–2004, a series of four periods of elevated long-period seismic activity, each lasting about 1–2 months, occurred at Shishaldin Volcano, Aleutian Islands, Alaska. The time periods are termed swarms of repeating events, reflecting an abundance of earthquakes with highly similar waveforms that indicate stable, non-destructive...

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...
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...
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...
