Assessment of peat quality by molecular and bulk geochemical analysis: Application to the Holocene record of the Chautagne marsh (Haute Savoie, France) (2008)

Disnar, Jean-Robert, Jacob, Jérémy, Morched-Issa, Mayssa, Lottier, Nathalie, Arnaud, Fabien

Although it is primarily constituted in general from a limited variety of local plants, peat is however sensitive to physicochemical changes in the medium, in particular those induced by hydrological...

Nutrient dynamics at the sediment–water interface in a Mediterranean lagoon (Thau, France): Influence of biodeposition by shellfish farming activities (2007)

Mesnage, Valérie, Ogier, Sylvie, Bally, Gabriel, Disnar, Jean-Robert, Lottier, Nathalie, Dedieu, Karine, ...

The Thau Lagoon, a French Mediterranean shallow lagoon, is a site where extensive shellfish farming occurs. The aim of the present work is to evaluate the role of this activity on nutrient exchange...

Organic insights into the bioprecipitation of carbonates in photosynthetic biofilms. A case study from La Laguna de Chiprana hypersaline lake (Spain). (2007)

Jacob, Jérémy, Gautret, Pascale, Défarge, Christian, Albéric, Patrick, Baillif, Patrick, Lottier, Nathalie

Within complex systems such as microbial mats formed in benthic environments, calcium carbonates are often associated with photosynthetic biofilms. This biocalcification regulates CO2, calcium and...

Peat-Forming plant specific biomarkers as indicators of paleoenvironmental changes in Sphagnum-dominated peatlands. (2007)

Laggoun-Défarge, Fatima, Gattinguer, Andreas, Comont, Laure, Disnar, Jean-Robert, Lottier, Nathalie, Gautret, Pascale, ...

The high preservation of organic material in peatlands that results from low pH, anoxia and rapid burial make the peat archives particularly useful for reconstructing natural or anthropogenic...
