The earth’s mountains continue to lose water. Glaciers are melting and mountain snow/rain balance tilts increasingly liquescent. Water is running off sooner—sometimes overfilling reservoirs, causing flooding, and setting the stage for late-season

The automated techniques used to collect pavement conditions on county roads are relatively expensive for local agencies. This study evaluates the possibility of reducing the amount of pavement condition data collected in each survey to optimize the

Earthquake swarms occur in many regions of the world. The study of earthquake swarms is very limited, and most contributions are descriptive. In this paper we propose use of a hidden Markov model to estimate the distribution of waiting times for swar

This paper presents a statistical approach named multivariate hidden Markov modeling (MHMM) and employs it to study the spatial and temporal distribution of earthquakes in the 1985 Yellowstone earthquake swarm. It also explores the potential of the a

This paper presents a novel theoretical framework for swarms of agents. Before deploying a swarm for a task, it is advantageous to predict whether a desired percentage of the swarm will succeed. The authors present a framework that uses a small group

Estimating abundance of carnivore populations is problematic because individuals typically are elusive, nocturnal, and dispersed across the landscape. Rare or endangered carnivore populations are even more difficult to estimate because of small sampl

Social disorganization theory attempts to explain the relationships of community characteristics and patterns of illicit drug use, but methamphetamine poses a problem for this perspective. Methamphetamine use is prevalent in rural areas, where greate

Ecologists conduct isotopic incorporation experiments to determine the residence time of various stable isotopes in animal tissues. These experiments permit determining the time window through which isotopic ecologists perceive the course of diet cha

Following Martin [Martin PS (1973) Science 179:969-974], we propose the hypothesis that the timing of human arrival to the New World can be assessed by examining the ecological impacts of a small population of people on extinct Pleistocene megafauna.

The performance of a naive Bayes classifier is compared with a well-established statistical classification approach, linear discriminant analysis, by considering core and log data from marine–eolian sediments. The results indicate that both methods
