Behavior and successful nesting of American oystercatchers on Falkner Island, Connecticut, in 1993 Behavior and successful nesting of American oystercatchers on Falkner Island, Connecticut, in 1993
Falkner Island, a two hectare unit of the Stewart B. McKinney National Wildlife Refuge, is located at 41°13'N, 72°39'W in Long Island Sound about 5 km south of Guilford, Connecticut. This island, described in detail by Helander (1988), is the nesting site of a mixed colony of several thousand Common Terns (Sterna hirundo) and a few hundred Roseate Terns (S. dougallii) (Spendelow 1994a,b)...

Keys to a successful project: Associated data and planning: Data standards Keys to a successful project: Associated data and planning: Data standards
The many individual salamanders, frogs, caecilians, and their larvae encountered during the course of an inventory or monitoring project will have to be identified to species. Depending on the goals and sampling method(s) used, some individuals will be identified from a distance by their calls, others will be handled. At the same time, some will be marked for recapture, and others will...

Wave climate and nearshore lakebed response, Illinois Beach State Park, Lake Michigan Wave climate and nearshore lakebed response, Illinois Beach State Park, Lake Michigan
The Lake Michigan outer nearshore zone (water depths ≈5 to 25 m) off Illinois Beach State Park is subjected to a spectrum of wave conditions, including those generated by major storms. Only under these major storm conditions is there a realistic potential for wave-lakebed interaction (and associated wind-driven currents) to cause a significant net modification to the outer nearshore...

U.S. Geological Survey yearbook, fiscal year 1993: At work across the Nation U.S. Geological Survey yearbook, fiscal year 1993: At work across the Nation
The need for earth science has never been more paramount. The devastating flooding of the Mississippi River this past year, strikingly portrayed on the cover and discussed in detail in this report (p. 37-42), was a sobering reminder of nature's elemental power. As a Nation, we face many environmental and economic challenges, such as natural hazards, that can be addressed effectively only...

Detection of Aeromonas salmonicida from water using a filtration method Detection of Aeromonas salmonicida from water using a filtration method
Aeromonas salmonicida is a principal pathogen that contributes to mortality in hatchery-maintained Atlantic salmon that originated from the Connecticut and Merrimack rivers in the northeastern United States. Field tests were conducted to assess a filtration method for detection of A. salmonicida in water used to rear fishes. A presumptive identification of typical A. salmonicida was...

Hydrologic processes controlling sulfate mobility in a small forested watershed Hydrologic processes controlling sulfate mobility in a small forested watershed
Hydrologic controls on sulfate mobility were investigated in a forested catchment in the Georgia Piedmont using a watershed mass balance approach. Variations in annual sulfate export were governed primarily by differences in runoff rather than by differences in sulfate deposition or in total annual precipitation. However, 2 years with similar total runoff had substantially different...
