Dipljapyx beroni n.sp. has been collected from two caves in Corsica. From its antennae with 31 articles, chaetotaxia of urites and subcoxal organs well-characterized, it appears to be an endemic Corsican species, situated between D. humberti Grassi found in the western Alps, and D. italicus Silv. peculiar to the Italian Peninsula. It is closely related to the first of those two species. There is no morphologic feature indicating it as a troglophilic species.
Three new species of harpacticoid copepods are described and discussed. Nitocrella beatricis n. sp. has been collected in different hyporheic sites in Sardinia and in two caves (Bue Marino cave in Sardinia and St. Barthélémy cave in Corsica); Elaphoidella janas n. sp. and Parastenocaris triphyda n. sp. have been collected only in Bue Marino cave. Some considerations concerning the ecology and biogeography of the three species are also presented.
The Oletta cave seems to be one of the largest underground caves in Corsica. The relationship between the organisation of the deforming strata and the karstic network shows that it is a karst of structural origin which has developed above the basic level. The karstification seems old and the speleothemes have to be connected with the phenomena of the climatic break of the Quaternary. Four types of fossiliferous infillings are known. The largest one is the oldest. They express the alternation of phases of sedimentation with different sedimentary dynamics. The most often found fauna is composed of mammals and gasteropoda. At least three faunal groups emerge: an old fauna with Cynotherium sardous, Nesoleipoceros cazioti and Enhydrictis sp. that can be attributed to the Early Wurm or to the limit of the Middle and Upper Pleistocene; a middle fauna to the terminal Wurm and which is characterised here by the absence of the three above mentioned mammals and lastly, a third group where the present fauna appears with, first, it seems, Rattus and Apodemus whereas Prolagus sardus persists for a long time

We studied genetic divergence in a group of exclusively stygobiont isopods of the family Stenasellidae. In particular, we assessed evolutionary relationships among several populations of Stenasellus racovitzai and Stenasellus virei. To place this study in a phylogenetic context. we used another species of Stenasellus, S. assorgiai, as an outgroup. S. racovitzai occurs in Corsica, Sardinia and in the fossil islands of the Tuscan Archipelago, while S. virei is a polytypic species widely distributed in the central France and Pyrenean area. This vicariant distribution is believed to be the result of the disjunction of the Sardinia-Corsica microplate from the Pyrenean region and its subsequent rotation. Since geological data provide time estimates for these events, we can use the genetic distance data to calibrate a molecular clock for this group of stygobiont isopods. The calibration of the molecular clock reveals a roughly linear relationship (r = 0.753) between the genetic distances and absolute divergence times, with a mean divergence rate (19.269 Myr/DNei,) different from those previously reported in the literature and provides an opportunity to shed some light on the evolutionary scenarios of other Stenasellus species.
Scuba observations (0 to -60 m) in Provence and Corsica and new data from Elba Island (Italy) indicate the bathymetric location of eustatic erosion levels in the Mediterranean Sea. A general sketch is given (standstill levels at-ii m, -17 m, -25 m, -35 m, -45 m, -50 m/55 m, -100 m). Isotopic data suggest contemporaneity of -100 m and -55 m levels with the two slow-down phases of Holocene transgression documented in Barbados and Tahiti coring (MWP-1A and 1B). Transgression acceleration after 14 000 BP explains the conservation of these littoral morphologies. Tectonics or isostasic movements (never more than 5 m) are prooved by differences observed in different areas of the world
Weathering formations resembling small caves, known by the name of Tafoni, are a characteristic, but not exclusive, feature of the Mediterranean area. Examples of such geomorphological formations have been recorded in Sardinia and Corsica (Klaer, 1956; Frenzel, 1965), in Tuscany (Martini, 1978), in S. Spain (Mellor et al., 1997) and in the Aegean Sea area (Greece) (Riedl, 1991; Hejl, 2005).
