Holocene land-use evolution and associated soil erosion in the French Prealps inferred from Lake Paladru sediments and archaeological evidences
19 février 2013
A source-to-sink multi-proxy approach has been performed within Lake Paladru (492 m a.s.l., French Prealps) catchment and a 6-m long sediment sequence retrieved from the central lacustrine basin. The combination of minerogenic signal, specific organic markers of autochthonous and allochthonous (...)
Urbanization, trace metal pollution, and malaria prevalence in the house sparrow.
28 janvier 2013
Anthropogenic pollution poses a threat for the environment and wildlife. Trace metals (TMs) are known to have negative effects on haematological status, oxidative balance, and reproductive success in birds. These pollutants particularly increase in concentration in industrialized, urbanized and (...)
Holocene land-use evolution and associated soil erosion in the French Prealps inferred from Lake Paladru sediments and archaeological evidences
21 janvier 2013
A source-to-sink multi-proxy approach has been performed within Lake Paladru (492 m a.s.l., French Prealps) catchment and a six-meter long sediment sequence retrieved from the central lacustrine basin. The combination of minerogenic signal, specific organic markers of autochthonous and (...)
The long and winding road: combining least cost paths and network analysis techniques for settlement location analysis and predictive modelling
9 janvier 2013
In this paper, we describe an exploratory analysis of the possibilities of combining least cost path analysis and network analysis techniques. Accessibility is a potentially important site location factor. So far, the definition of accessibility has been approached through the creation of (...)
Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions
8 janvier 2013
Peatlands contain approximately one third of all soil organic carbon (SOC). Warming can alter above- and belowground linkages that regulate soil organic carbon dynamics and C-balance in peatlands. Here we examine the multiyear impact of in situ experimental warming on the microbial food web, (...)
Coupling inter-patch movement models and landscape graph to assess functional connectivity
8 janvier 2013
Landscape connectivity is a key process for the functioning and persistence of spatially-structured populations in fragmented landscapes. Butterflies are particularly sensitive to landscape change and are excellent model organisms to study landscape connectivity. Here, we infer functional (...)

Les prairies : biodiversité et services écosystémiques
23 décembre 2012
À partir d'une analyse bibliographique, les auteurs étudient la composition, l'organisation et le rôle de la biodiversité des prairies permanentes en fonction de leur régime d'exploitation. Une première partie décrit la diversité des prairies, du paysage aux espèces. Une seconde est centrée sur les (...)
Metamorphic and geochronogical study of the Triassic El Oro metamorphic complex, Ecuador: Implications for high-temperature metamorphism in a forearc zone
7 décembre 2012
In the forearc of the Andean active margin in southwest Ecuador, the El Oro metamorphic complex exhibits a well exposed tilted forearc section partially migmatized. We used Raman spectroscopy on carbonaceous matter (RSCM) thermometry and pseudosections coupled with mineralogical and textural (...)
Introducing the human factor in predictive modelling: a work in progress
19 octobre 2012
In this paper we present the results of a study into integrating socio-cultural factors into predictive modelling. So far, predictive modelling has largely neglected the social and cultural dimensions of past landscapes. To maintain its value for archaeological research, therefore, it needs new (...)
Introduction of a combination vector to optimise the interpolation of numerical phantoms
21 juillet 2012
Phantoms are 3-dimensional (3D) numerical representations of the contours of organs in the human body. The quality of the dosimetric reports established when accidental overexposures to radiation occur is highly dependent on the phantom's reliability with respect to the subject. EquiVox is a (...)

Thermodynamic modeling and thermobarometry of metasomatized rocks
3 juin 2011
Determining the P-T conditions at which metasomatism occurs provides insight into the physical conditions at which fluid-rock interaction occurs in the crust. However, application of thermodynamic modeling to metasomatized rocks is not without pitfalls. As with "normal" metamorphic rocks, the (...)
