Abstract:
Recent negative trends in the Florida Bay ecosystem have been attributed to human activities, however, neither the natural patterns of change, nor the pre-human baseline for the environment have been determined. The major objectives of this project are 1) to determine patterns of faunal and floral change over the last 150-200 years, and 2) to explore associations between biotic changes and anthropogenically-induced changes and/or natural changes in the physical environment. Environmental managers and policy makers responsible for restoring the Everglades ecosystem to a "natural state" can use these data to make economical and realistic decisions about restoration goals and to determine interim steps to ameliorate further damage to the ecosystem.

The history of the ecosystem during the last 150-200 years is studied by analysis of faunal and floral assemblages from a series of shallow cores taken in Florida Bay. Cores are located at strategic sites in Florida Bay, with initial emphasis on the northeast and northern portions of the Bay where the most significant changes are thought to have occurred. These cores are submitted for Pb 210 analysis to determine the age and degree of disruption of the sediments. Cores that present a good stratigraphic record are sampled at closely spaced intervals for all macro-and micro-fauna and flora present. Quantitative down-core assemblage diagrams are drawn up and the various faunal and floral data are compared to look for correlated changes among the groups analyzed. Determinations of salinity, bottom conditions, nutrient supply and various other physical and chemical parameters of the environment are made for each sample based on the fauna and flora present. Data from all cores will be integrated to search for regional patterns of change in diversity and distribution of the fauna and flora, and data from Florida Bay will supplement and be correlated to onshore data and to Biscayne Bay (Ecosystems History: Terrestrial and Fresh Water Ecosystems of Southern Florida Project and Ecosystems History: Biscayne Bay and the southeast coast Project). The integrated data set will be analyzed to see if detected changes in biota correlate to alterations in physical parameters and/or historic records of human-induced modifications of the environment.

Purpose:
This project is one component of an interdisciplinary study of the ecosystem history in Florida Bay. A number of USGS and other agencies scientist's are examining a series of shallow cores (~1-2 m) collected from Florida Bay. By studying the patterns of change that have occurred in the ecosystem over the last two centuries, we gain insight into the natural processes, including the natural range of variability that exists within any ecosystem. We can then determine the degree to which anthropogenic-induced change has effected the system. This understanding is critical to the restoration effort; otherwise we will be attempting to restore the system to a targeted snapshot in time, without understanding how realistic or obtainable those goals are. The ecosystem history component of the initiative will save time and money by providing realistic, economical, obtainable goals.

Our component of this study is to analyze the down-core faunal and floral assemblages, over the last 150-200 years. Cores are located at strategic sites in Florida Bay, with initial emphasis on the northeast and northern portions of the Bay where the most significant changes are thought to have occurred. These cores are submitted for Pb 210 analysis to determine the age and degree of disruption of the sediments. Cores that present a good stratigraphic record are sampled at closely spaced intervals for all macro- and micro-fauna and flora present. Quantitative down-core assemblage diagrams are drawn up and the various faunal and floral data are compared to look for correlated changes among the groups analyzed. Determinations of salinity, bottom conditions, nutrient supply and various other physical and chemical parameters of the environment are made for each sample based on the fauna and flora present. Data from all cores will be integrated to search for regional patterns of change in diversity and distribution of the fauna and flora, and data from Florida Bay will supplement and be correlated to onshore data and to Biscayne Bay. The integrated data set will be analyzed to see if detected changes in biota correlate to alterations in physical parameters and/or historic records of human-induced modifications of the environment.

Process_Description:
Flora and fauna were analyzed from a series of Pb-210 dated shallow cores collected in Florida Bay. Core data will be compared to data from modern sampling sites within Florida Bay. Cores are retained by Bob Halley and Charles Holmes in the USGS St. Petersburg, FL. office. Processed faunal and floral samples are retained at the USGS in Reston, VA.

1) Cores or bottom samples are collected from strategic sites in Florida Bay.

2) Cores are a) visually examined, b) x-rayed, and c) Pb210 profiles are developed. These 3 methods determine if the sediments within the core are disrupted. If the core seems to be undisturbed, then processing proceeds.

3) Samples for sedimentologic, palynologic, charcoal, and isotopic analyses are removed.

4) Portions of the cores and the surface samples are washed through sieves down to 63 microns for calcareous samples.

5) Palynologic, and charcoal analyses proceed through a series of acidulation processes and slides prepared for counting of dinocysts, pollen grains, and charcoal.

6) Calcareous samples are dried and picked for mollusks, benthic foraminifera and ostracodes. Counts of taxa present are made.

7) Percent abundance diagrams are constructed. Core data is compared to modern analogue data for information on salinity and substrate preferences of species. Data from all faunal and floral groups are combined and analysis completed.

The field data contained in this database have not been reviewed for publication and therefore may contain inconsistencies or errors. The field measurements (such as salinity and temperature) were made on an variety of instruments over the years. Project personnel have made every attempt to calibrate and standardize the instruments and check the data, however, the field data should be considered preliminary. Also taxonomic names may not represent the most up to date usage, but are internally consistent.
