Developing a habitat-driven approach to CWWT design Developing a habitat-driven approach to CWWT design
A habitat-driven approach to CWWT design is defined as designing the constructed wetland to maximize habitat values for a given site within the constraints of meeting specified treatment criteria. This is in contrast to the more typical approach of designing the CWWT to maximize treatment efficiency, and then, perhaps, adding wildlife habitat features. The habitat-driven approach is...

Field results of antifouling techniques for optical instruments Field results of antifouling techniques for optical instruments
An anti-fouling technique is developed for the protection of optical instruments from biofouling which leaches a bromide compound into a sample chamber and pumps new water into the chamber prior to measurement. The primary advantage of using bromide is that it is less toxic than the metal-based antifoulants. The drawback of the bromide technique is also discussed.

Flow and suspended particulate transport in a tidal bottom layer, south San Francisco Bay, California Flow and suspended particulate transport in a tidal bottom layer, south San Francisco Bay, California
Field investigations of the hydrodynamics and the resuspension and transport of particulate matter in a bottom boundary layer were carried out in South San Francisco Bay, California during March-April 1995. The GEOPROBE, an instrumented bottom tripod, and broad-band acousti Doppler current profilers were used in this investigation. The instrument assemblage provided detailed measurements...

Identification of polar bear den habitat in northern Alaska Identification of polar bear den habitat in northern Alaska
The goal of this project is to refine the information collected previously on maternal denning, into digital maps that show where polar bears are likely to create future dens in northern Alaska. Such maps will allow a priori recommendations regarding timing and geographic locations of proposed human developments; and hence provide managers with an important mitigation and management tool...

Integrating across scales: Effectively applying science for the successful conservation of Atlantic salmon (Salmo salar) Integrating across scales: Effectively applying science for the successful conservation of Atlantic salmon (Salmo salar)
Atlantic salmon (Salmo salar) is an excellent species on which to focus synthetic, integrative investigations because it is an economically important species that captures the public imagination, is heavily impacted by humans, uses several ecosystems over its life, and is the subject of a large body of extant literature. The following 24 papers were solicited to provide the biological...

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...
