Abstract
The aim of this project is to inventory the Aracbnida and Myriapoda fauna of the State of São Paulo, within the BIOT A-FAPESP program. This study will be based on an extensive collection program, covering various different areas of the State of São Paulo and other states in the country, for a comparison between different fitogeographic areas and their fauna composition. In addition to São Paulo, we have selected areas in surrounding States and in many other States that present interesting comparison areas, such as Central Westem (Cerrado) and the Northeast (Mata de Tabuleiro). FOUT groups, three aracbnids (Araneae, Opiliones and Acari) and one Myriapod (Chilopoda), will have priority during the project, since these are the most abundant in diversity, number of specimens, in samplings and specialists. The collection program will be carried out over two years. FOUT collection methods will be used and the sampling effort will be standardized, in order to sample the arachnid and myriapod fauna of these biomes as much as possible, to obtain data on the composition and species richness of the sampled areas and compare them. The sampling methodology will consist basically of manual collection, mainly at night, beating trays, pitfall traps and Winckler extractor. The collections should last for one week to ten days in each area. The material obtained will be deposited in the arachnida and myriapoda collections of the Butantan Institute and the Zoology Museum of the University of São Paulo. A poison bank will be created, with the extraction from the specimens collected alive in order to begin the citogenetic study of various species, with initial priority being given to the Theraphosidae spiders.The species richness will be calculated using three methods of analysis: Log Normal Distribution, Species Accumulation Curve and the Jackknife standard (JACKl¬SD). These three methods will by analysed by the EstimateS5 version 5.0.1 program. The richness and abundance of spiders in each area will be compared through Variance Analysis (ANOVA), and the difference between the groups will be detected according to Tuckey Test. The project envisions a series of products for the scientific community, students and general public on the orders of Arachnids and Myriapods, such as: inventory of the arachnid and myriapoda fauna of the state; ample and representative collections of the arachnida and myriapoda fauna of the state; computerization the collections of the Butantan Institute...
