    Benthos communities of Vendicari and Capo Passero, two potential MPA’s in South Eastern Sicily (Italy)

    ABSTRACT
    In the present paper a bionomic study and cartography of the benthos of two potential MPAs in South Eastern Sicily, S.C.I. ITA 090027 “Fondali di Vendicari” and the S.C.I. ITA 090028 “Fondali dell’Isola di Capo Passero”, and surrounding areas are presented. The goals of this particular survey can be summarized as follows: 1) to chart the benthic communities (and the area of each one); 2) to evaluate the benthic diversity of the areas; 3) to produce visual documentation of the distributions of the benthic organisms; 4) to identify human-induced pressures on the benthic environment; 5) to make recommendations for future management based on the visual assessment; and 6) to set up a new methodology for making large biocenosis maps that would help to manage marine protected and non-protected areas. The fauna and flora of the meso- and macrobenthos were studied by a triple sampling procedure: standard, visual and photographic samples were simultaneously taken along underwater transects. These, together with the floristic and faunistic study of each algal and invertebrate group, served as the basis for the bionomic survey of the Vendicari and Capo Passero Island sea bottoms. In a first approach, the supra- and mediolittoral communities were studied. Further work were focused on the infralittoral stages and their communities along representative transects. The survey was conducted from surface (+0.50 m) to 40 metres of depth that is the limit of the study site. During this study were found, also, 41 benthic species and many biocoenoses of high naturalistic value protected by many international law agreements. The study led to a comprehensive review of the main biotope systems of this coastal area, as well as their environmental condition, and this will be an essential element for their future management.
