  • Biodiversity and infectious diseases: Impact of human activities on the sylvatic transmission cycle of leishmaniases in French Guiana.

    Kocher , Arthur (2017)
    The dilution effect hypothesis states that more diverse ecological communities are less prone to pathogen transmission because of the presence of non-competent hosts acting as epidemiological dead-ends. In this work, we investigate the existence of this phenomenon in the case of zoonotic cutaneous leishmaniases in French Guiana. Molecular tools based on high-throughput sequencing technologies have been developed to study the epidemiological system. These tools were employed to explore leishma...

    Accounting for Life-History Strategies and Timescales in Marine Restoration

    Montero-Serra , Ignasi; Garrabou , Joaquim; Doak , Daniel; Figuerola , Laura; Hereu , Bernat; Ledoux , Jean-Baptiste; Linares , Cristina (2017)
    International audience; Understanding the drivers of restoration success is a central issue for marine conservation. Here, we explore the role of life-history strategies of sessile marine species in shaping restoration outcomes and their associated timescales. A transplantation experiment for the extremely slow-growing and threatened octocoral Corallium rubrum was highly successful over a relatively short term due to high survival and reproductive potential of the transplanted colonies. Howev...

    Instabilité des prix alimentaires dans les pays en développement. La nécessaire intervention publique pour stabiliser les prix. ---- Food price instability in developing countries. The need for public intervention to stabilise prices

    Galtier, Franck (2009)
    N°2 - Pour faire face à l'instabilité des prix alimentaires, les pouvoirs publics des PED doivent intervenir en utilisant des instruments adaptés au type d'instabilité.; Les crises alimentaires de 2005 au Sahel et de 2008 sur les marchés internationaux ont remis la question de l'instabilité des prix alimentaires au coeur des débats. Les émeutes urbaines engendrées par la flambée des prix de 2008 dans une quarantaine de pays en développement (PED) rappellent que cette instabilité peut avoir de...

    Infrared Spectroscopy for the Characterization and Quality Control of Moringa Oleifera : a Multivariate Approach

    Rébufa , Catherine; Pany , I; Dupuy , Nathalie; Bombarda , Isabelle (2017)
    International audience; Moringa oleifera is known for its nutritional and therapeutic potential. This potential is linked to the chemical composition whose variability according to the ecological characteristics and development processes (from harvesting to packaging) can be significant. The influence of parameters such as altitude, weather conditions (temperature, humidity, precipitation), parts of the plant used as well as the influence of the processes for extracting active compounds, the ...

    Additive or non-additive effect of mixing oak in pine stands on soil properties depends on the tree species in Mediterranean forests

    Brunel , Caroline; Gros , Raphael; Ziarelli , Fabio; Farnet Da Silva , Anne Marie (2017)
    International audience; This study investigated how oak abundance in pine stands (using relative Oak Basal Area %, OBA%) may modulate soil microbial functioning. Forests were composed of sclerophyllous species i.e. Quercus ilex mixed with Pinus halepensis Miller or of Q. pubescens mixed with P. sylvestris. We used a series of plots with OBA% ranging from 0 to 100% in the two types of stand (n = 60) and both OLF and A-horizon compartments were analysed. Relations between OBA% and either soil c...
