An overview of the population histories of three insular realms (Gargano palaeo-archipelago, Sardinia-Maritime Tuscany palaeobioprovince and the Sicilian insular complex) during the Late Miocene and Quaternary are here presented. The complexity of biodiversity changes in the islands is analysed to propose an interpretation of origination and extinction patterns. The study highlighted several important aspects of insular faunas. Evolutionary radiations were found to contribute significantly only to the Gargano faunal diversity, likely because the area was an archipelago at the time.Another interesting result is that large and small mammals do not disperse and become extinct all at the same time on each island. In fact, because of their distinct body sizes, large and small mammals have different dispersal ability and therefore different chances to cross-filtering barriers. But distinct body sizes means also different influence on diversity, resistance to environmental changes and likelihood of extinction. Another important point is that large mammalian carnivores at the top of the trophic net are quite more fragile and susceptible to become extinct than other predators.The study finally shows the clear influence that the intense Middle and Late Pleistocene climate-driven environmental changes had on island communities. The reconstruction of the faunal histories of Sardinia and Sicily shows that without exchanges with the mainland the island system represents a rather stable refuge area not too affected by the changes in the ''physical'' parameters of the environment. In contrast, if the island is frequently connected with the continent, insular faunal assemblages tend to behave as their mainland counterparts. r

“…[15] The structural setting of the wedge consists of a thinskinned fold and thrust belt, while the frontal part is characterized by a foredeep basin; both of them migrated eastward from the Late Oligocene to present [Ricci Lucchi, 1986;Vai, 1989;Boccaletti et al, 1990aBoccaletti et al, , 1990bPatacca and Scandone, 1989, 2001]. The foredeep is filled by 3000 to 5000 m of siliciclastic turbidites, which represent syn-orogenic deposits.…”

“…[16] Both the Barbados and Apennines arcs are characterized by a west directed subduction, linked to an eastward migration of the slab [Pindell et al, 1988;Boccaletti et al, 1990aBoccaletti et al, , 1990bGueguen at al., 1997Gueguen at al., , 1998Doglioni et al, 1999aDoglioni et al, , 1999b (Figure 3). The migration of the Northern Barbados Ridge is related to the evolution of the Caribbean area, that can be defined as a relative motion of about 1100 km in an approximately eastward direction since the Eocene with respect the North America plate [Briden et al, 1979;Pindell et al, 1988;Pindell and Barrett, 1990].…”

Décollement depth versus accretionary prism dimension in the Apennines and the Barbados

et al. 2003

Along representative cross sections of the Apennines and the Northern Barbados accretionary prisms, we measured the area, the décollement depth, the angle α of the upper envelope and the angle β of the dip of the regional monocline. The continental sections of the Apennines accretionary prism have a deeper décollement than the oceanic sections of the Northern Barbados, 6–10 km depth and <1 km depth, respectively, because the sediment pile is thinner on the incoming Barbados plate and its denser oceanic structure is more easily subducted. Considering the frontal 50 km, the Apennines have an average cross‐sectional area of 500 km2 and the Northern Barbados Ridge of 100 km2. The total area is a function of the depth of the décollement plane. Therefore, at a given amount of subduction, the deeper the décollement depth is, the bigger the area of the wedge will result, assuming negligible compaction and erosion. As a consequence, the larger area/volume and higher elevation of the Apennines with respect to the Barbados is determined by the Apenninic deeper décollement. Despite these differences, the geometry of both décollements is, in some cases, comparable, in particular, close to the boundary between the crystalline crust and the sediment pile, where the main density and strength contrasts are concentrated. Variations in depth of the décollement occur moving along strike in both accretionary prisms. The geometry of the prisms is further controlled by the different values of α and β, their sum, and the distance of the accretionary prism relative to the subduction hinge.
