A metabolism-based trophic index for comparing the ecological values of shallow-water sediment habitats A metabolism-based trophic index for comparing the ecological values of shallow-water sediment habitats
We determined fluxes of oxygen and nutrients between water and sediments at 21 sites primarily in Virginia and North Carolina estuaries, over the past 15 yr. These sites represented broad ranges in salinity, tidal amplitude, hydrology, nutrient availability, turbidity, light availability, depth, sediment grain size, and anthropogenic disturbance. In general, we found that...

Analysis of a Lake Superior coastal food web with stable isotope techniques Analysis of a Lake Superior coastal food web with stable isotope techniques
Food-web components of a Lake Superior coastal wetland and adjacent offshore waters were examined with stable isotope ratio techniques for carbon and nitrogen. We found distinct carbon isotope ratio signatures for organisms collected in the wetland and from offshore. Both food-web groups seemed to be based on carbon fixed by phytoplankton. Compared to offshore organisms, the wetland food...

Ecosystem management: A decision support GIS approach Ecosystem management: A decision support GIS approach
This paper describes a new approach using decision support GIS for handling information in ecosystem management. Technical research efforts resulted in specialized spatial decision support systems for wetland restoration planning, wetland permit analysis, and wildlife research and management. These applications are briefly presented to illustrate the usage of the methodology. With its...

Lipid and water depletion in migrating passerines following passage over the Gulf of Mexico Lipid and water depletion in migrating passerines following passage over the Gulf of Mexico
Lipid depletion is currently believed to be the primary factor limiting flight duration of migrating birds in North America, while the influence of water loss is thought to be small. Three migrating species of passerines, wood thrush (Hylocichla mustelina), Swainson's thrush (Catharus ustulatus), and summer tanager (Piranga rubra) were captured during the 1993 spring migration just after...

Food availability and feeding preferences of breeding fulvous whistling-ducks in Louisiana ricefields Food availability and feeding preferences of breeding fulvous whistling-ducks in Louisiana ricefields
Expansion of the breeding distribution of the Fulvous whistling-duck (Dendrocygna bicolor) into the southeastern United States after the mid-1800s coincided with the establishment of rice (Oryza sativa) cultures in Texas, Louisiana, and Florida. In southern Louisiana, where approximately 80% of rice is aerially seeded in water, Fulvous whistling-ducks are suspected of feeding extensively...

Biomass patterns in seagrass meadows of the Laguna Madre, Texas Biomass patterns in seagrass meadows of the Laguna Madre, Texas
The Laguna Madre of Texas supports the most extensive seagrass meadows in the western Gulf of Mexico, In 1988 seagrasses covered 730 km2 or about three-quarters of the embayment. Halodule wrightii dominated the entire upper laguna, and total biomass was quite uniform near 160 g˙m-2 throughout. Four species shared dominance in the lower laguna. Where present mean biomass of Thalassia...
