    On the presence of Dreissena polymorpha (Pallas, 1771) and Sinanodonta woodiana woodiana (Lea, 1834) in Sicily (Mollusca Bivalvia)

    ABSTRACT
    In this paper we report on the presence of two non-native and invasive species of bivalve mollusks in Sicily: Sinanodonta woodiana woodiana (Lea, 1834) (Bivalvia Unionidae) native to East Asia and Dreissena polymorpha (Pallas, 1771) (Bivalvia Dreissenidae) native to the Ponto-Caspian area, with a particular focus on how the presence of these alien species can lead to imbalances in the delicate equilibrium of Sicilian freshwater invertebrates and, above all, does threaten the existence of Unio elongatus gargottae Philippi, 1836 an island's native bivalve suffering from strong rarefaction.

    Terrestrial molluscs from the R.N.I. “Grotta Conza” (Palermo, Sicily) (Gastropoda Architaenioglossa Pulmonata)

    ABSTRACT
    The results of a study on the fauna of terrestrial molluscs from the R.N.I. "Grotta Conza" (Palermo, North-Western Sicily) are here described. Research has allowed us to compile a checklist of 41 species, 18 of which are endemic to Sicily. For each species ecological and distributional data are provided.
