Restoration of the Drugeon River and adjacent wetlands (northeastern France): impact on breeding birds
3 mai 2012
The channelizing of the minor bed of the Drugeon river and the drainage of adjacent marshes were carried out from 1961 to 1973 in the hope of gaining 2000 ha of farmland. Those works led to important damage to the wetlands of the Drugeon basin, a Ramsar site since 2003, under the protection of (...)
Partitioning of Cd and Pb in the blood of European blackbirds (Turdus merula) from a smelter contaminated site and use for biomonitoring.
16 avril 2012
Blood composition is commonly measured to assess exposure to and effects of metals on birds. In most of passerine species, only small volumes of blood may be sampled safely (<500 µL), which limit the measure of several markers of health status and chemical residues. Here, we documented the (...)
Hydrogéologie : objets, méthodes, applications (3ème édition)
12 avril 2012
L'hydrogéologie, science de l'eau souterraine, a pour objectif de planifier au mieux l'exploitation des ressources en eau. Elle doit donc identifier des aquifères ou nappes d'eau souterraine, mais elle doit, surtout aujourd'hui, protéger et gérer les ressources en eau. L'hydrogéologie, c'est aussi (...)

Characterizing the Feeding Habits of the Testate Amoebae Hyalosphenia papilio and Nebela tincta along a Narrow "Fen-Bog" Gradient Using Digestive Vacuole Content and (13)C and (15)N Isotopic Analyses.
26 mars 2012
Population dynamics and feeding habits of the testate amoebae Nebela tincta and Hyalosphenia papilio were studied along a short "fen" to "bog" gradient in a Sphagnum-dominated mire (Jura, France). Samples were collected in living "top segments" (0-3cm) and early declining "bottom segments" (...)
Phenoloxidase and peroxidase activities in Sphagnum-dominated peatland in a warming climate
26 mars 2012
Peatlands still suffer from the scarcity of available data about the characterization and the response to climate forcing of the main oxidative enzymes that occur over the seasons. In the present study, phenoloxidase and peroxidase activities were examined in Sphagnum lawns along a narrow (...)
Factors influencing the microbial composition of metalworking fluids and potential implications for machine operator's lung.
26 mars 2012
Hypersensitivity pneumonitis, also known as "machine operator's lung" (MOL), has been related to microorganisms growing in metalworking fluids (MWFs), especially Mycobacterium immunogenum. We aimed to (i) describe the microbiological contamination of MWFs and (ii) look for chemical, physical, (...)

Modelling of landscape connectivity is a key point in the study of the movement of populations within a given landscape. For studies focused on the preservation of biodiversity, graph-based methods provide an interesting framework to investigate the landscape influence on population spread (...)
BSAFs for freshwater fish and derivation of a sediment quality guideline for PCBs in the Rhone basin, France
21 février 2012
Purpose Since 2005, freshwater fish contamination by polychlorobiphenyls (PCBs), polychlorodibenzodioxins, and polychlorodibenzofurans has been assessed in the Rhone River basin (France). A large database of surface sediment contamination by PCBs is also available, opening the way to the study (...)

A 2500 year record of natural and anthropogenic soil erosion in South Greenland
5 décembre 2011
The environmental impact of the Norse landnám in Greenland has been studied extensively. But to date, no study has quantified the soil erosion that Norse agricultural practices are believed to have caused. To resolve this problem, a high resolution sedimentary record from Lake Igaliku in South (...)
Techniques d'amendement agraire et témoins matériels : pour une approche archéologique des espaces agraires anciens
26 août 2011
Depuis les années 1970, l'archéologie a connu un élargissement constant de ses champs d'investigation, déplaçant notamment son intérêt du site au territoire.

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 (...)
