Using landscape ecology to test hypotheses about large-scale abundance patterns in migratory birds Using landscape ecology to test hypotheses about large-scale abundance patterns in migratory birds
The hypothesis that Neotropical migrant birds may be undergoing widespread declines due to land use activities on the breeding grounds has been examined primarily by synthesizing results from local studies. Growing concern for the cumulative influence of land use activities on ecological systems has heightened the need for large—scale studies to complement what has been observed at local...

Dimethylsulfoniopropionate as a potential methanogenic substrate in Mono Lake sediments Dimethylsulfoniopropionate as a potential methanogenic substrate in Mono Lake sediments
A high concentration of dimethylsulfoniopropionate (DMSP) was found in the water column (0.1–1.8 µM particulate plus dissolved) of Mono Lake, CA, an alkaline, hypersaline waterbody. The dense Artemia monica population contained high levels of DMSP (1.7–2.5 mmol.g-1 wet weight), presumably as an osmolyte. Death of these brine shrimp caused accumulation of DMSP along the shoreline of the...

Dependence of waterbirds and shorebirds on shallow-water habitats in the Mid-Atlantic coastal region: An ecological profile and management recommendations Dependence of waterbirds and shorebirds on shallow-water habitats in the Mid-Atlantic coastal region: An ecological profile and management recommendations
Waterbirds (waterfowl, colonially nesting wading and seabirds, ospreys [Pandion haliaetus], and bald eagles [Haliaeetus leucocephalus]) and shorebirds (sandpipers, plovers, and relatives) may constitute a large fraction of the toplevel carnivore trophic component in many shallow-water areas of the mid-Atlantic region. The large biomass of many species (>1 kg body mass for the two raptors...

Silver Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Silver Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Ecological and toxicological aspects of silver (Ag) in the environment are briefly summarized with an emphasis on natural resources. Elevated silver concentrations in biota occur in the vicinities of sewage outfalls, electroplating plants, mine waste sites, and silver-iodide seeded areas; in the United States, the photography industry is the major source of anthropogenic silver...

On NAAMP and the use of the Internet as a forum for evolving science On NAAMP and the use of the Internet as a forum for evolving science
Traditionally, science has been communicated through peerreviewed hardcopy. With the rapid growth of internet technology, many new potentials for sharing and evolution of ideas are possible: open, low cost communication between researchers, both accredited and amateur, may allow not joint problem solving at scales previously not possible. Conservation especially, is a dynamic field which...

The relevance of the Mediterranean Region to colonial waterbird conservation The relevance of the Mediterranean Region to colonial waterbird conservation
The Mediterranean Sea is the largest partially enclosed sea in the world and provides habitat to more than 100 species of waterbirds from the Palearctic-North African-Middle Eastern regions. Even though the Mediterranean suffers from pollution, has little tidal influence, and is oligotrophic, more than half of the western Palearctic populations of numerous waterfowl species winter in the...

Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania
A water-use analysis computer program was developed for the Neshaminy Creek Basin to assist in managing and allocating water resources in the basin. The program was developed for IBM-compatible personal computers. Basin analysis and the methodologies developed for the Neshaminy Creek Basin can be transferred to other watersheds. The development and structure of the water-use analysis...
