A dynamic landscape model for fish in the Everglades and its application to restoration A dynamic landscape model for fish in the Everglades and its application to restoration

A model (ALFISH) for fish functional groups in freshwater marshes of the greater Everglades area of southern Florida has been developed. Its main objective is to assess the spatial pattern of fish densities through time across freshwater marshes. This model has the capability of providing a dynamic measure of the spatially-explicit food resources available to wading birds. ALFISH...

Mapping and converting essential Federal Geographic Data Committee (FGDC) metadata into MARC21 and Dublin Core: towards an alternative to the FGDC Clearinghouse Mapping and converting essential Federal Geographic Data Committee (FGDC) metadata into MARC21 and Dublin Core: towards an alternative to the FGDC Clearinghouse

The purpose of this article is to raise and address a number of issues related to the conversion of Federal Geographic Data Committee metadata into MARC21 and Dublin Core. We present an analysis of 466 FGDC metadata records housed in the National Biological Information Infrastructure (NBII) node of the FGDC Clearinghouse, with special emphasis on the length of fields and the total length...

A method for measuring vertical accretion, elevation, and compaction of soft, shallow-water sediments A method for measuring vertical accretion, elevation, and compaction of soft, shallow-water sediments

High-resolution measures of vertical accretion, elevation, and compaction of shallow-water sediments are fundamental to understanding the processes that control elevation change and the mechanisms of progradation (e.g., development of mudflats and intertidal wetlands) in coastal systems. Yet, measurements of elevation by traditional survey methods often are of low accuracy because of the

A flow cytometric approach to the study of crustacean cellular immunity A flow cytometric approach to the study of crustacean cellular immunity

Responses of hemocytes from the crayfish Procambarus zonangulus to stimulation by fungal cell walls (Zymosan A) were measured by flow cytometry. Changes in hemocyte physical characteristics were assessed flow cytometrically using forward- and sidescatter light parameters, and viability was measured by two-color fluorescent staining with calcein-AM and ethidium homodimer 1. The main...

Climate change: Potential impacts and interactions in wetlands of the United States Climate change: Potential impacts and interactions in wetlands of the United States

Wetlands exist in a transition zone between aquatic and terrestrial environments which can be altered by subtle changes in hydrology. Twentieth century climate records show that the United States is generally experiencing a trend towards a wetter, warmer climate; some climate models suggest that his trend will continue and possibly intensify over the next 100 years. Wetlands that are...

Diversity, distribution, and conservation status of the native freshwater fishes of the southern United States Diversity, distribution, and conservation status of the native freshwater fishes of the southern United States

The Southeastern Fishes Council Technical Advisory Committee reviewed the diversity, distribution, and status of all native freshwater and diadromous fishes across 51 major drainage units of the southern United States. The southern United States supports more native fishes than any area of comparable size on the North American continent north of Mexico, but also has a high proportion of...

Florida manatee now resident in the Bahamas Florida manatee now resident in the Bahamas

In January 2000, both the Bahamas National Trust and the Save the Manatee Club received reports of a manatee at Bullocks Harbor, Great Harbour Cay, Bahamas. Under permit with the Bahamas’ Department of Fisheries, I visited Great Harbour Cay from 25 to 27 February 2000 to make a field assessment of the manatee, interview local residents, and provide management recommendations. Detailed...

Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands? Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands?

White band disease (WBD) ravaged Acropora palmata (elkhorn coral) on many coral reefs in the Caribbean in the late 1970’s and 1980’s, including those around St. John and St. Croix, U. S. Virgin Islands—USVI (Gladfelter 1982, Rogers 1985). Quantitative data, photographs, and anecdotal observations indicate WBD killed large stands of elkhorn coral in the USVI from about 1976 until sometime...
