La crypte archéologique de la collégiale de Saint-Quentin (Aisne)
2011
La courte campagne archéologique de 2010 avait pour objet un certain nombre de vérifications et de relevés préparant la synthèse finale. À la suite de cette intervention, les nouveaux éléments sur le terrain se situent essentiellement au nord. Entre les vestiges en place d'un fragment de mosaïque (dans les niveaux viie-viiie siècle) et le mur de chaînage de l'abside (ixe siècle), un espace restreint a pu être descendu et a mis en évidence des relations stratigraphiques entre deux états de sols en béton de tuileau, déjà reconnus lors des campagnes antérieures, datés du ve siècle, avec un massif quadrangulaire enduit, d'environ 1,40 m sur 0,80 m. Une fois rasé, son emplacement a été bouché pa…
Adopting encryption to protect confidential data in public clouds: A review of solutions, implementation challenges and alternatives
2015
A shift towards use of public cloud services is ongoing and more and more enterprises will start to use them in the near future. As public cloud services certainly promise to deliver many benefits, this new way of delivering services also introduces new types of risks. Due to the NSA’s surveillance programs, non-US enterprises need to reassess the risks of public cloud services provided by US companies and look for available solutions to protect their confidential data transferred and stored in the cloud. Encryption is seen as a solution to help enterprises full fill the requirements related to security and privacy, but is often challenging to implement. Encryption has its own security prob…
Origin of the natural variation in the storage of dietary carotenoids in freshwater amphipod crustaceans
2020
Carotenoids are diverse lipophilic natural pigments which are stored in variable amounts by animals. Given the multiple biological functions of carotenoids, such variation may have strong implications in evolutionary biology. Crustaceans such as Gammarus amphipods store large amounts of these pigments and inter-population variation occurs. While differences in parasite selective pressure have been proposed to explain this variation, the contribution of other factors such as genetic differences in the gammarid ability to assimilate and/or store pigments, and the environmental availability of carotenoids cannot be dismissed. This study investigates the relative contributions of the gammarid g…
Molecular phylogeny of the genus Chondrina (Gastropoda, Panpulmonata, Chondrinidae) in the Iberian Peninsula
2022
[EN] Chondrina Reichenbach, 1828 is a highly diverse genus of terrestrial molluscs currently including 44 species with about 28 subspecific taxa. It is distributed through North Africa, central and southern Europe, from Portugal in the West to the Caucasus and Asia Minor in the East. Approximately 70% of the species are endemic to the Iberian Peninsula constituting its main center of speciation with 34 species. This genus includes many micro endemic taxa, some of them not yet described, confined to limestone habitats (being strictly rock-dwelling species). They are distributed on rocky outcrops up to 2000 m.a.s.l. It is a genus of conical-fusiform snails that differ mainly in shell characte…
Species size affects hatching response to different temperature regimes in a rotifer cryptic species complex
2013
The strategy of decreasing size with increasing temperature known as Bergmann’s rule operates at geographic scale and in spite of extensive studies still presents a puzzle to researches. The aim of this work was to verify whether patterns of diapausing egg hatching of closely related species are consistent with the expectations from Bergmann’s rule. In a laboratory study of the cryptic species complex of the rotifer Brachionus plicatilis, the response to temperature (17.5, 22.5, and 25.0 °C) of diapausing eggs collected in a pond where the three tested species coexist was assessed by (1) the number of hatchlings emerging or (2) the time needed to hatch. Our results show that the response to…
