Abstract

Human activities frequently lead to the conversion of natural habitats into human mediated ones. Land use transformation is an important form of global pressure as affects biodiversity, and gradually causes soil functionality loss. Therefore, soil biodiversity loss may cause significant alteration of regulatory services of terrestrial ecosystems. The analysis of taxonomical and functional structure of microarthropod communities is revealing to be an useful tool to understand changes in soil functionality, in soils with different anthropoic pressure. The work aimed to assess how anthropic impact affects Mediterranean soil quality and functionality. In particular, the work evaluated the ecotoxicology of metal polluted urban soils through laboratory bioassays and field studies, in order to investigate the relationship between the responses of standard organisms and the field communities, in a gradient of metal pollution. Then, urban soils were compared with other soil management to highlight possible differences in soil physical and chemical properties and taxonomic and functional structure of Collembola community among different land uses. Urban soils were collected in September 2010 (Autumn) and April 2011 (Spring) in the urban area of Naples city, whereas soil undergone to different land uses (natural, urban, industrial and agricultural) were collected in Naples and surroundings in October 2011 (Autumn) and March 2012 (Spring). The soils were analysed for principal physical and chemical properties. Taxonomy and fuctional traits of Collembola community were analysed. In urban soil, organic matter content and metal contamination were the main driving forces in assembling the arthropods within the community. Collembola seemed the most sensitive taxon to urbanization. In fact, Collembola functional traits highlighted wide differences among the land uses. Collembola with bigger size, pigmented and with sexual reproduction were found mainly in agricultural soils. Detritivorous Collembola were abundant everywhere, whereas herbivorous Collembola were mainly found at urban and natural soils.
