Relationships of saproxylic beetles with forest structure, deadwood and microhabitats in the Abeti Soprani wood. The aim of the study was to evaluate the influence that the structure of the forest, the features of the deadwood and the microhabitats have on abundance, distribution and diversity of the saproxylic beetles in a forest ecosystem. The activities were carried out in the fir forest “Abeti Soprani”, located in the territory of the Molise region, Italy. Fifty areas were selected in a wooded area of 230 hectares, using two sampling methods: windows fly trap for insects in flight and eclectors for insects inside the deadwood. In each sampling area, the forest structure, the components of deadwood and the presence of microhabitats were quantified and described. The relationship between the structural forest parameters and the beetles was analyzed. Moreover, geostatistical analysis was conducted to highlight the spatial pattern of the examined parameters and the distribution of the monitored fauna. The results confirmed various relationships of insects with forest structure, deadwood and microhabitats. In particular, the following associations were more frequently observed: living plant mass (m³\ha) with the number of species, saproxylic species, Elateridae, Cerambycidae and Curculionidae; snags (trees\ha) with the number of specimens, families and Staphylinidae; microhabitats on deadwood with the number of families, Staphylinidae and Cerambycidae.
