    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.
