Integrating ecosystem studies: A Bayesian comparison of hypotheses Integrating ecosystem studies: A Bayesian comparison of hypotheses
Ecosystem studies are difficult to interpret because of the complexity and number of pathways that may affect a phenomenon of interest. It is not possible to study all aspects of a problem; thus subjective judgment is required to weigh what has been observed in the context of components that were not studied but may have been important. This subjective judgment is usually a poorly...

Large-area mapping of biodiversity Large-area mapping of biodiversity
The age of discovery, description, and classification of biodiversity is entering a new phase. In responding to the conservation imperative, we can now supplement the essential work of systematics with spatially explicit information on species and assemblages of species. This is possible because of recent conceptual, technical, and organizational progress in generating synoptic views of...

Measurements of coastal storm surge by the U.S. Geological Survey Measurements of coastal storm surge by the U.S. Geological Survey
In the wake of a storm, local, state, and federal emergency planners needed storm surge elevation data as quickly as possible. These data are used by officials to decide what areas are in the greatest need of assistance and what areas qualify for special designations. To accelerate the pace at which storm surge data can be gathered and released, the US geological survey (USGC) has...

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...

Movement, migration, and smolting of Atlantic salmon (Salmo salar) Movement, migration, and smolting of Atlantic salmon (Salmo salar)
A variety of movements characterize the behavioral plasticity of Atlantic salmon (Salmo salar) in fresh water, including movements of fry from redds, establishment of feeding territories, spawning movements of sexually mature male parr, movement to and from winter habitat, and smolt migration in spring. Smolting is an adaptive specialization for downstream migration, seawater entry, and...

On sediment and habitat in the Upper Animas River watershed, Colorado On sediment and habitat in the Upper Animas River watershed, Colorado
The Upper Animas River watershed in southwestern Colorado is located in the San Juan mountains and has been intensively mined. Active mining has essentially ceased but the impact of past mining on the aquatic ecosystem continues. This paper presents initial results from a study to determine the characteristics of the physical habitat for aquatic animals and the sediment characteristics...

Operational modeling system with dynamic-wave routing Operational modeling system with dynamic-wave routing
A near real-time streamflow-simulation system utilizing continuous-simulation rainfall-runoff generation with dynamic-wave routing is being developed by the U.S. Geological Survey in cooperation with the Du Page County Department of Environmental Concerns for a 24-kilometer reach of Salt Creek in Du Page County, Illinois. This system is needed in order to more effectively manage the...
