Changes in food resources and conservation of scarab beetles: from sheep to dog dung in a green urban area of Rome (Coleoptera, Scarabaeoidea)
No full textThe aim of the research was to show how a change in land use influences the structure of a dung beetle assemblage and affect its
conservation. In the Pineto Urban Regional Park (Rome), dog dung is the sole food resource currently available for scarab dung
beetles, after the recent removal of wild and domestic herbivores. A one-year sampling was conducted to study the scarab assemblage
in dog scats (1999) and to compare it with the previous assemblage associated with sheep droppings (1986). Richness, evenness
and similarity parameters were compared between the two allochronic assemblages. From sheep to dog dung, an impoverishment of
the total richness was observed (from 19 to 9 species) together with an increase of individuals (by 7 times). Dog dung harboured 20%
of the current scarab dung beetle fauna of Rome, probably as a consequence of the dog mixed diet, rich in cellulose. Both the communities
showed a high percentage of tunnellers, probably because of the food shortage and, for dog scats, of the high dehydration
rate. A comparison with other Roman scarab communities enhanced that: (1) the change in food resource determined a higher difference
in species composition respect to other parameters (size and habitat diversity); (2) dog dung provided a temporary refuge for
species that otherwise may encounter local extinction in urban environments.

Checklist e distribuzione della fauna italiana. Insecta Coleoptera Scarabaeoidea
No full textI Coleotteri Scarabeoidei della fauna italiana sono stati l'oggetto di una raccolta intensiva di dati faunistici ed ecologici che ha permesso di ottenere una database nazionale su disposizioni del Ministero dell'Ambiente e della Tutela del Territorio (Direzione per la Protezione della Natura) che ha finanziato la ricerca. L'articolo riassume i risultati generali dell'indagine esaminando la diversità tassonomica del gruppo in questione nel nostro paese (famiglia per famiglia)e mettendo in evidenza le specie endemiche, rare, localizzate o minacciate da estinzione
