    Qanat, Gebbie and water source: the last refuge for the malacologica freshwater fauna in Palermo (Sicily, Italy)

    ABSTRACT
    The surroundings of Palermo were characterized, over the centuries, by the presence of many natural environments of great ecological and faunal importance. These environments were placed in a context characterized by minimal and sustainable urban development and large agriculture areas, dedicated to the development of tree crops such as citrus and orchards. These crops were supported by an imposing irrigation system that, using natural resources such as watercourses, wells and springs, collected and distributed water in soils through tanks, gebbie, qanat, irrigation channels (saje), etc. Fresh water mollusks, like many other animal and vegetable organisms, spread from the natural freshwater environments in this artificial water system, thus creating a unique and varied ecosystem. The subsequent urban development of the city of Palermo and the destruction of many of those natural environments has further enhanced the ecological role of the artificial freshwater systems as an important refuge for the native fauna and flora. In the present study, we report on freshwater molluscs observed in the territory of Micciulla, a large relict area occupied almost entirely by an old citrus, now located inside the city of Palermo. In this area there are some springs, an extensive array of artificial freshwater to irrigate the crops, and the qanat Savagnone located in the “Camera dello Scirocco”. The results obtained by census of different populations of freshwater mollusks confirm the importance of these environments and the growing role they play as the last refuges for fauna and flora originally linked to natural humid environments.

    Longhorn beetles of the Ficuzza woods (W Sicily, Italy) and their relationship with plant diversity (Coleoptera Cerambycidae)

    ABSTRACT
    The woods in Sicily are the result of centuries of anthropogenic activities that have reduced the surface of wood and changed the original composition even with the introduction of alien species to native flora. The value in terms of biodiversity of these forests remains, however, high for they are the last refuge areas for many animals and plant species. This study was conducted within the Ficuzza woods (West Sicily), extended about 5,000 hectares on the slopes of limestone-dolomite rock of Busambra (1615 m asl), within which lies the largest remaining forest area in western Sicily. It is an area with a wide diversity of vegetation, represented mainly by native forests (holm oak, cork oak, deciduous oaks), groups of riparian vegetation, shrubs, bushes, grasslands, and of non-native forest formations (Pinus and Eucalyptus woods). The study on Cerambycidae in this area is fragmented and does not specify a relation the species with the surrounding vegetation. This study was performed by choosing among various groups of insects, xylophagous Coleoptera Cerambycidae; existing literature data and extensive collected field data were reviewed. The analysis was also performed by the collection of dead wood in order to distinguish the relationship between the plant species and coleoptera. The results summarize and supplement the data registered so far, shedding further light on the ecological role of this group of insects that are also valid biomarkers of the integrity and complexity of the forest.

    Making smart use of woody alien plants

    ABSTRACT
    It is unquestionable that some alien woody plant species are a major issue for biodiversity conservation. However, being alien species generally adapted to warmer conditions than natives, they could be particularly suited to cope with the new environmental and climatic conditions that are also forecasted in the coming decades in Sicily. This poses an issue that is not easy to deal with, whether trying to use these species for the advantages they could bring, for instance in the new reforestation activities, while avoiding them becoming a serious problem for biodiversity conservation in natural and seminatural areas. Here, we present some study cases of non-native tree species which represent emblematic examples in that regard: Acacia saligna and A. cyclops, Eucalyptus spp., Leucaena leucocephala, Opuntia ficus-indica and Ailanthus altissima. These tree species are very invasive in some ecological contexts, while being useful to meet ecological services in others. A sound planning activity could help distinguish where planting these species could be not only possible but also desirable, from areas where their presence should be totally avoided.
