Fox baiting against Echinococcus multilocularis: Contrasted achievements among two medium size cities.
11 mai 2013
In Europe, most cities are currently colonized by red foxes (Vulpes vulpes), which are considered to be the main definitive host of the zoonotic cestode Echinococcus multilocularis. The risk of transmission to humans is of particular concern where high fox populations overlap with high human (...)
Ammonia exposure promotes algal biomass in an ombrotrophic peatland

Since 2008, the French guidelines have promoted the systematic use of 30 mg/day of primaquine for the radical cure of Plasmodium vivax and Plamodium ovale infections. We observed three relapses in 10 patients with P vivax acquired in French Guiana. No relapses were seen in West African P ovale (...)
Landscape effects in small mammal populations exhibiting density outbreaks and on their interactions with predators and parasites
23 mars 2013
Some species of small mammals (rabbits, prairie dogs, pikas, voles, etc.) have been traditionally perceived as pests and targeted for control on a very large scale despite their importance as key-stone species in their native ecosystems. During the 90s, a number of studies have shown that small (...)

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 (...)

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, (...)

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 (...)
