ABIOTIC FILTERING OF BENTHIC INVERTEBRATE GUILDS IN THE MARGHERITA DI SAVOIA SALT PAN, ITALY

The structure of biological communities is a result of the combined action of an environmental selection, determined by the physico-chemical characteristics of an ecosystem. This process results in the selection of the species depending on their tolerances (abiotic filter) and their ability to cope with the interactions among species (biotic filter).
