Title: A Bibliography of South Florida Wading Birds.
Name/Creator: Kushlan, James A., Baumann, M. Christine, McEwan, Linda C.
Abstract/Description: The wading birds of south Florida have attracted the attention of naturalists, biologists and conservationists for decades. These species of herons, ibis, spoonbils, and storks have figured importantly in national and international conservation efforts and in the establishment of natural preserves such as Everglades National Park and Corkscrew Swamp Sanctuary. Regional population decreases caused initially by hunting and then by loss of habitat are well known.

Show moreThe intent of this report is to provide a bibliography of the hydrologic literature, both historic and current, concerning the Everglades area, which includes the Conservation Areas and Everglades National Park, and the Big Cypress Swamp, which includes the Big Cypress National Preserve (Figure 1 and 2). These areas represent the southern portion of the Kissimmee River- Lake Okeechobee Watershed, with the Conservation Areas and the Big Cypress providing the bulk of the overland flow into the Park (Figure 3). The hydrology of the basin is a system of complex relationships, and determines the unique ecological environment of the area. Through man's manipulations in his efforts to farm, urbanize and industrialize South Florida, he has altered the historic flow regime of the area. This in turn affected the biological environment in a chain reaction attendant to such a sensitive, interdependent system.

Twenty sampling stations were established--eight to document larval entry into Florida Bay and adjacent estuarine waters, and 12 within Florida Bay and adjacent estuarine waters, to provide insight into larval fish distribution and movement. Spotted seatrout was the only target species whose larvae were regularly collected; gray snapper snook, and red drum apparently spawn outside of the park. Other findings include an abundance of gobiid larvae throughout the study sites. Maps of the study sites showing larvae distribution are included.

Show moreThis study documents the recent environmental history of northern Biscayne Bay using vertical aerial photographs combined with field studies and supplemented with data onthe pre-urban setting and the timing of urban developments and natural stresses. Aerial photographic surveys from 1925 and 1976 provided the basis for mapping important changes in terrestrial and submerged bay bottom environments. Where major changes were identified, aerial photography from numerous intermediate dates yielded additional information on the timing and specific character of change., The maps delineate overall long-term increases in developed land and disturbed bottom areas (dredged and spoil bottoms), decreases in mangrove land and benthic vegetation areas, and changes in man-grove, bulkheaded, and sloping shorelines in the Bay. Man induced changes were found to pervasive on land and along shorelines. Dredging and island construction within the Bay has disturbed 19 percent of the existing bay bottom. The major changes in the character of the Bay's terrestrial margins were caused by filling of swamps, expansion of original land areas, and the creation on new islands. Changes in the benthic environments result from: 1) circulation changes related to inlet and causeway construction, 2) direct dredging operations, and 3) increasing turbidity levels. Benthic vegetation has decreased over most of the study area except in the northernmost areas where substantial increases occurred following the opening of Bakers Haulover Inlet., Aerial photographs record the effects of the major hurricanes of the 1920's and 1930's. These storms destroyed large acreages of coastal mangroves and they produced localized erosion of benthic plant communities. The amount and location of change produced by each storm was highly variable and some small storms had significant effects., Analysis of sediment cores taken in substrates distrubed at known times yielded long-term sedimentation rates of 2.9 to 3.4 mm per year for northern Biscayne Bay.

Three hundred twenty-five fish ranged in length from 284-940 mm FL and in weight from 0.7 - 11.6 kg. Mean lengths of fish were largest in spring and smallest in winter. There were no differences in mean length among areas of capture. Annulus formation occurred in spring (March-May). Ages of fish were mainly 4-5 year-olds. Recruitment to the fishery began at age 2 and was completed at age 6., The overall sex ratio favored males 3/1 and there were no differences in mean age of fish among areas of capture. Mean calculated growth of all snook was 375 mm FL in the first year and 57-90 mm thereafter. Calculated fish lengths at age differed among areas of capture and sexual differences in length-weight relationship were noted. Annual mortality rate of all fully recruited fish was 78%. Sexual differences in mortality rates were discussed.

Show moreAn extreme drawdown of the Alligator Chain and Lake Gentry to reverse the decline of aquatic habitat associated with years of lake level stabilization has been proposed. The project area is located southeast of St.Cloud in Osceola County,Florida. During the drawdown, approximately 3,450 acres of bottom sediments will be exposed, simulating the historic cycle of flood and drought which maintained the lakes' ecological balance. Also associated with the drawdown will be the removal of approximately 475,000 cubic yards of organic material (muck) from the lake bottom. This habitat enhancement project was initiated by public concerns for protection of their resource. Although the lakes' water quality is good, the prospect of cleaner shorelines, less nuisance vegetation and organic material, and an improved sport fishery has engendered a great deal of support for this project from homeowners and other area residents who utilize these lakes (see Appendix A for more detailed overview of the proposed drawdown project).

The authors compared data collected biweekly during a 22 month period (December 1977- September 1979) among rain gauge networks containing 87, 29, 11 and 3 gauges. These results were also compared with data collected daily at three long-term NOAA stations located on the periphery of the study area. A comparison between managed surface water inflows and uncontrolled precipitation contributions to the slough during this time was also made. Data from the three long-term NOAA stations were further used to compute a reconstruction of direct rainfall inputs into the slough on a monthly and yearly basis for the period 1952 to 1979.

Relative abundance, proportion of females, and number of juveniles were highest in Everglades National Park from Lostman's River northward. Juveniles were never found at most stations sampled in Florida Bay. The primary source of adult crabs in Florida Bay appears to be from the Gulf of Mexico., Spatial and temporal variations in the distribution, abundance, size class frequency, sex ratio, and reproductive activity of stone crabs Menippe mercenaria was studied in south Florida coastal waters and existing knowledge of the species was synthesized. Abundance of juveniles and adults was highest and mean size was smallest from Lostman 's River northward. Abundance decreased and mean size increased with movement southward through Florida Bay. Juvenile distribution and abundance was directly related to abundance of adults and proportion of females in the trapped population. BNP resembled Florida Bay in number and size of adults and lack of juveniles., Temporal changes in abundance, sex ratio and size class frequency of adults were correlated to reproductive activity and water temperature and corresponded to commerical fishing season offshore, and in Florida Bay. Females bear eggs in summer and become sexually mature by age three. Molting occurs from fall through spring in females, increase in CW by 10 mm with each molt and can live to age seven. Males may molt year-round with a mean molt increment of 16 mm CW for crabs greater than 70 mm CW. Males undergo a greater mortality rate than females apparently due to their greater susceptibility to commercial fishing pressure., Study Period:June 1979-June 1980; Study Type:Quantitative; Biological Component:Xanthid Crab; Habitat:Mud, sand, shell, rock, coral; Gear Type:Crab Trap; Abiotic Parameters Measured:Salinity, water temp; Dominant Taxon/Taxa Studied:Menippe mercenaria., The report includes sections on seasonal distribution, sex ratio, size composition, growth and mortality, and reproduction (NRBIB)., Abstract prepared by T.W.
