    Analysis of the vascular flora of four satellite islets of the Egadi Archipelago (W Sicily), with some notes on their vegetation and fauna

    ABSTRACT
    This paper represents the first contribution on the vascular flora of the stack named Faraglione di Levanzo and of three satellite islets of Favignana, i.e. Prèveto, Galeotta and a stack located at Cala Rotonda. A sketch of their vegetation pattern is also provided, as well as a list of all the terrestrial fauna, with some more detailed information on the vertebrates. The finding of some bones of Mustela nivalis Linnaeus, 1758 is the first record for the whole archipelago and deserves further investigations. The floristic data have been used in order to analyze life-form and chorological spectra and to assess species-area relationship, the peculiarity of local plant assemblages, the occurrence of islet specialists, the risk of alien plants invasion and the refugium role played by the islets. The significant differences among the check-lists compiled by the two different couples of authors during their own visits to Prèveto and Galeotta underline the need of planning regular and standardized field investigations in order to avoid an overestimation of local species turnover rates.

    Terrestrial gastropods of the minor islets of the Maltese Archipelago (Mollusca Gastropoda)

    ABSTRACT
    For this study, the terrestrial malacofauna of minor islets of the Maltese archipelago was investigated. A number of new records were found and synthesized with previous records to produce a comprehensive list of species. A brief commentary on the population, environment, habitat, and morphology for most species is given.

    A contribution to the knowledge of the terrestrial Mammalian fauna of Comino and its satellite islets (Maltese Archipelago)

    ABSTRACT
    The present work aims to contribute to existing knowledge on Mammalia species occurring on Comino and its satellite islets and to provide additional records collected between the years 1998-2012. At the present state of knowledge, on the islands of the Maltese Archipelago there are 19 different species of terrestrial mammals (Erinaceomorpha: Atelerix algirus. Soricomorpha: Suncus etruscus, Crocidura sicula. Chiroptera: Rhinolophus ferrum-equinum, R. hipposideros, Miniopterus schreibersii, Myotis punicus, Eptesicus serotinus, Nyctalus noctula, Pipistrellus pygmaeus, P. kulii, Plecotus austriacus, Tadarida teniotis. Lagomorpha: Orictolagus cuniculus. Rodentia: Apodemus sylvaticus, Rattus rattus, R. norvegicus, Mus musculus. Carnivora: Mustela nivalis), more than half of which are bats. Out of 13 species listed here, 8 species are represented as new to the islands while 3 species are confirmed and 2 species are listed as unlikely occurring.

    Flora of some of the satellite islets of Sicily, Pantelleria, Lampedusa and Ustica (Italy)

    ABSTRACT
    During the last decade, the authors visited several stacks (Faraglione) which are satellites islets around the main circum-sicilian islands. Most of these stacks are inaccessible to the general public due to their geographical and topographical positions/inclinations. Literature is often scarce or non-existent. The current work provides a preliminary data on the floral diversity recorded during the brief expeditions between the years 2008–2018. All of these islets were observed once, so this study does not reflect all of the possibly existing species of these islets. The current study caters the Faraglione di Colombara of Ustica, Isola dei Conigli, Scoglio del Sacramento and Scoglio di Faraglione of Lampedusa, Faraglione di Tracino and Faraglione di Ficaria/indietro l’isola of Pantelleria. Another islet is the Scoglio dello Zio Gennaro, Taormina, Sicily.
