Durability of calcarenitic hypogea in the underground cultural heritage of Palermo (Sicily)
2011
The paper deals with the stability conditions of hypogea, several hundred m 2 wide, dating from the Punic period to the XIX century, dug out of the calcarenitic table that makes up the bedrock of the Plain of Palermo in the Fossa della Garofala. This work concerns the influence that the shape of the hypogea and the characteristics of the lithotypes wields on the instability and decay phenomena taking place, by mean of laboratory tests on the calcarenite and parametric numerical models. The comparison between the numerical models and the actual instability phenomena validated the use of the empirical formula of Hoeck to the mechanical characterization of complex structured rock-mass in soft …

Revision of Recent and fossil Mixtacandona Klie 1938 (Ostracoda, Candonidae) from Italy, with description of a new species
2017
Although studies on ostracods dwelling in inland subterranean habitats of Italy have increased in the last decades, highlighting a considerable taxonomic diversity, available information is still far from sufficient to understand phylogenetic and biogeographic relationships. Mixtacandona Klie 1938 is one of the most common and diverse genera of ostracods in subterranean waters. Of the 20 living recognized species in the genus, all stygobiontic and restricted to the Palearctic Region, four are known for the Italian peninsula and Sardinia, one of which exclusively as fossil. Several other Recent and fossil taxa attributable to Mixtacandona, but identified at supraspecific level, have been rep…
Energy and speleogenesis: Key determinants of terrestrial species richness in caves
2017
Abstract The aim of this study was to unravel the relative role played by speleogenesis (i.e., the process in which a cave is formed), landscape‐scale variables, and geophysical factors in the determination of species richness in caves. Biological inventories from 21 caves located in the southeastern Iberian Peninsula along with partial least square (PLS) regression analysis were used to assess the relative importance of the different explanatory variables. The caves were grouped according to the similarity in their species composition; the effect that spatial distance could have on similarity was also studied using correlation between matrices. The energy and speleogenesis of caves account…
Pathologies et traumatismes professionnels au Néolithique ; des mineurs de silex à Chouilly « la Grifaine » (Marne) ?
2021
La fouille réalisée en 2016 par le service archéologique de Reims Métropole sur le site de Chouilly « La Grifaine » a été l’occasion de compléter nos connaissances sur les hypogées de la Marne. L’examen détaillé de l’état sanitaire des sujets issus de l’hypogée F10 a mis en exergue la récurrence de différents traumatismes et de lésions dégénératives qui plaident en faveur d’une activité spécifique qui pourrait être en lien avec l’extraction du silex. Les indices ostéologiques concernent essentiellement les individus inhumés dans les niveaux les plus récents et témoignent, soit d’une modification du recrutement des individus inhumés, soit d’une évolution des activités au cours du temps. The …
