Using geostatistical methods to estimate snow water equivalence distribution in a mountain watershed Using geostatistical methods to estimate snow water equivalence distribution in a mountain watershed
Knowledge of the spatial distribution of snow water equivalence (SWE) is necessary to adequately forecast the volume and timing of snowmelt runoff. In April 1997, peak accumulation snow depth and density measurements were independently taken in the Loch Vale watershed (6.6 km2), Rocky Mountain National Park, Colorado. Geostatistics and classical statistics were used to estimate SWE...

Information-theoretic model selection and model averaging for closed-population capture-recapture studies Information-theoretic model selection and model averaging for closed-population capture-recapture studies
Specification of an appropriate model is critical to valid statistical inference. Given the “true model” for the data is unknown, the goal of model selection is to select a plausible approximating model that balances model bias and sampling variance. Model selection based on information criteria such as AIC or its variant AICc, or criteria like CAIC, has proven useful in a variety of...

A policy model to initiate environmental negotiations: Three hydropower workshops A policy model to initiate environmental negotiations: Three hydropower workshops
How do I get started in natural resource negotiations? Natural resource managers often face difficult negotiations when they implement laws and policies regulating such resources as water, wildlife, wetlands, endangered species, and recreation. As a result of these negotiations, managers must establish rules, grant permits, or create management plans. The Legal‐Institutional Analysis...

Viewpoint: Sustainability of piñon-juniper ecosystems - A unifying perspective of soil erosion thresholds Viewpoint: Sustainability of piñon-juniper ecosystems - A unifying perspective of soil erosion thresholds
Many pinon-juniper ecosystem in the western U.S. are subject to accelerated erosion while others are undergoing little or no erosion. Controversy has developed over whether invading or encroaching pinon and juniper species are inherently harmful to rangeland ecosystems. We developed a conceptual model of soil erosion in pinon-jumper ecosystems that is consistent with both sides of the...

Evaluating landscape health: Integrating societal goals and biophysical process Evaluating landscape health: Integrating societal goals and biophysical process
Evaluating landscape change requires the integration of the social and natural sciences. The social sciences contribute to articulating societal values that govern landscape change, while the natural sciences contribute to understanding the biophysical processes that are influenced by human activity and result in ecological change. Building upon Aldo Leopold's criteria for landscape...

Modeling and management of water in the Klamath River Basin: overcoming politics and conflicts Modeling and management of water in the Klamath River Basin: overcoming politics and conflicts
The network flow model MODSIM, which was designed as a water quantity mass balance model for evaluating and selecting water management alternatives, has been applied to the Klamath River basin. A background of conflicting issues in the basin is presented. The complexity of water quantity model development, while satisfying the many stakeholders and involved special interest groups is...

Noninvasive monitoring of fetal growth and development in the Siberian polecat (Mustela eversmanni) Noninvasive monitoring of fetal growth and development in the Siberian polecat (Mustela eversmanni)
The Siberian polecat (Mustela eversmanni) is the preferred species to assess procedures and establish normative values for application in the related and endangered black-footed ferret (Mustela nigripes). This study was undertaken to physically, ultrasonographically, and radiographically evaluate fetal development in a spontaneously breeding captive Siberian polecat population
