“…provincialis a slightly higher glycosidic activity for the lactose substrate. The similarity of the glycosidic activity for sucrose and maltose may indicate a common foraging zone; according to previous studies, both species were active in the same beach zone, the eulittoral one Fallaci et al 2002).

“…The Burano sandy beach (Tuscany, Italy) was studied as a model ecosystem for Mediterranean beaches, and a large data background has been developed (Chelazzi et al 1990;Scapini et al 1992;Colombini et al 1994;Fallaci et al 1994Fallaci et al , 1996Fallaci et al , 1997Fallaci et al , 2002Aloia et al 1999). The macroarthropods of this beach-dune system present abundant populations that were studied for zonation and life cycle.…”

“…The beach was exposed and micro-tidal; the analysed community had a common detritivorous (mostly) terrestrial diet (Chelazzi et al 1990;Scapini et al 1992;Colombini et al 1994;Fallaci et al 1994Fallaci et al , 1996Fallaci et al , 1997Fallaci et al , 2002Aloia et al 1999). The dune and fore dune have a typical Mediterranean vegetation cover, where the following plants were found from the extralittoral zone (dune) to the shoreline, along with the captures of the animals.…”

Arthropod communities of beach-dune systems are mainly composed by detritivorous species, apparently with overlapping trophic niches. This study aims at distinguishing the trophic roles of sympatric species, by using a biochemical approach in the analysis of gut contents. The digestion of seven trisaccharidic and disaccharidic substrates containing the glycosidic bond was tested in gut homogenates of 10 species of detritivorous insects and crustaceans from a Mediterranean beach-dune system (Tuscany, Italy). Glycosidase activities were compared between species. A dendrogram was determined separating species with different enzymatic activity spectra. The differences observed in the enzymatic activities may be related to a different use of the available food resources and interpreted as an opportunist nutrition of arthropod species sharing the same habitat.

“…In this study, Formicidae and Tenebrionidae represented 88% of the total catch and therefore were mainly responsible for the temporal fluctuations in abundance observed in the insect community. Positive correlations between temperature and total captures of both, ants and beetles, in temperate zones have been documented, reflecting parallel seasonal patterns in temperature and adults' emergence, foraging activity, and reproductive and diapauses periods (Whitford et al, 1981;Stevens et al, 1998;Fattorini and Carpaneto, 2001;Fallaci et al, 2002). Studies on Formicidae have shown that different species exhibit greater foraging activity in the summer months and lower in spring and autumn, being null in winter; its surface activity is closely associated with temperatures above 20 C, with optimum temperatures around 30 C and limiting temperatures below 15 C (Whitford et al, 1981;Retana et al, 1992).…”

Impact of anthropogenic disturbances on beetle communities of French Mediterranean coastal dunes

et al. 2007

In coastal dunes, inXuenced by anthropogenic activities such as tourism, it is important to determine the relative inXuence of environmental factors at diVerent spatial scales to evaluate the sensitivity of local communities to disturbances. We analyzed beetle communities of 14 dunes of the French Mediterranean coast: four in the relatively preserved Camargue area, and ten in the Var department, where tourism is intensive. Beetle communities were studied three times in early spring using sand sampling. Species-environment relationships were evaluated at the regional, landscape and local scale using redundancy analysis (RDA) and variability partitioning. About 28 species were identiWed, of which 15 were sand-specialist species, which accounted for more than 93% of total abundance. The beetle communities of Camargue were signiWcantly diVerent from those of the Var department owing to the pullulation of a Tenebrionid species (Trachyscelis aphodioides Latr.) in the Var, except for one restored dune where the community was very similar to those of Camargue. Our results showed no longitudinal gradient between the two regions. Local factors (dune height, preservation and disturbance index) signiWcantly explained most of the variation in the dominance of T. aphodioides, while some other local factors were important for other psammophilous species. This study also suggests that dune beetle communities are strongly aVected on beaches intensively managed for tourism, but beetles are still abundant in much disturbed sites.
