Abstract: This data set includes the results of the activities undertaken in the REVIZEE Program by the South Score/Benthos (Cabo de São Tomé, RJ Arroio Chuí, RS). The main objectives of this sub-program are the knowledge of biodiversity and the evaluation of the sustainable potential of the faunistic resources of the exclusive economic zone of the southeastern and southern regions of Brazil. The field ... collections were taken from December 13th 1997 to April 20th 1998 in the continental shelf and slope (60 - 810 m depth) with the Oceanographic Vessel Prof. W. Besnard (IO-USP).
The fauna was collected using the benthic samplers van Veen and Box-corer and the rectangular dredge, summing up 322 samples. In some cases, data of organisms scrapped from hard substrates were also presented. The following groups are presented: Porifera, Cnidaria (Hydrozoa, Scyphozoa and Anthozoa), Sipuncula, Mollusca (Gastropoda, Bivalvia, Cephalopoda, Polyplacophora and Solenogastres), Annelida (Polychaeta), Crustacea (Ostracoda, Cirripedia, Decapoda, Stomatopoda and Tanaidacea), Bryozoa, Brachiopoda, Echinodermata (Ophiuroidea, Asteroidea, Crinoidea, Holothuroidea and Echinoidea) and Chordata (Ascidiacea). A total of 131,369 individuals were recorded and classified into 28 higher taxa. The most abundant and frequent groups were Porifera, Cnidaria, Sipuncula, Gastropoda, Bivalvia, Scaphopoda, Polychaeta, Crustacea, Ophiuroidea, Bryozoa and Brachiopoda. Bryozoa was the most abundant group (30,501 records) followed by Polychaeta (22,412 inds), Ophiuroidea (16,918), Crustacea (14,240), Brachiopoda (12,834) and Bivalvia (11,761).
The collected data reveal a very rich fauna. The structure of the benthic fauna in the study area was characterized by the association between higher abundances of organisms with sandy and muddy substrata, both with low contents of calcium carbonate (100 - 200 m). The bathymetric distribution of the higher taxa was also demonstrated to be associated with the substrate type. The higher taxa recorded in this study are being analyzed by experts to enable a more precise evaluation of the biodiversity. A total of 1012 taxa were identified up to date and a significant number of new occurrences and new species were reported. The identified material was placed in biological collections of museums or institutions with curatorial tradition.

Quality The ongoing goals in the ATLSS Program have been to produce models capable of projecting and comparing the effects of alternative scenarios on various trophic components of the Everglades. ATLSS models delivered in 2003 include:
Vegetation Succession Model
America Crocodile Model
Crayfish Structured Population Model
In ... addition, the ATLSS Program is supporting the development of a Decision Support System. This is to go beyond ad-hoc policy formulation to an analytical and computer-supported platform for effective management and policy-making. Part of this effort involves developing a GIS interface to the ATLSS models and providing network access to ATLSS models.
: Work planned for FY 2004 includes four projects needed to continue applications of the ATLSS program to CERP (Comprehensive Everglades Restoration Plan). These projects are: 1. ATLSS Model Use in CERP Evaluations, Model Testing, and Extension to Web Based Interface, 2. Development of an Internet Based GIS to Visualize ATLSS Datasets, 3. Spatial Decision Support for Biodiversity and Indicator Species Responses to CERP Project Activities, and 4. Integrating Wading Bird Empirical Data into a Model of Wading Bird Foraging Success as a Function of Hydrologic Conditions. The individual project metadata contain more detailed information about each project.
