PhD proposal within M-TROPICS: pathogen bacteria transport and fate in the tropical critical zone

This PhD proposal aims at better understanding the transport and fate of pathogen bacteria in tropical areas, e.g. fecal pathogens such as the Fecal Indicator Bacteria (FIB) Escherichia coli and the environmental pathogen Burkholderia pseudomallei. The methods suggested to be implemented in this PhD will be a mix of in situ observations, field and laboratory […]

The roots of the drought: Hydrology and water uptake strategies mediate forest-wide demographic response to precipitation

An inter-disciplinary team at Bengaluru’s Indian Institute of Science (IISc) studied how different tree species partition underground water resources up to 30m depth and co-existing tree species diverge in water uptake depths (M-TROPICS/BVET). Deep rooted trees turn to be more vulnerable to severe droughts than shallow rooted species : climate change-type droughts could then affect […]

Processes controlling silicon isotopic fractionation in a forested tropical watershed: Mule Hole Critical Zone Observatory (Southern India)

The analyses of silicon isotopes in soil, water and plant compartments of the Mule Hole forested watershed (M-TROPICS/BVET) reveal that vegetation takes up twice more silica than first estimates using elemental mass balance. This flux is 30 times higher than the solute silica flux exported by the stream, itself resulting principally from litter decay. The […]

Origin of silica in rice plants and contribution of diatom Earth fertilization: insights from isotopic Si mass balance in a paddy field

This study (M-TROPICS/BVET) identified and quantified the Si sources to rice plants using a solute mass balance at soil-plant scale and the silicon isotopic signatures of the various Si pools. It reveals that the main Si sources are soil amorphous silica, irrigation water and to a lesser extent Si fertilizer when it was applied. In […]

Etude de la sédimentation du réservoir de la Maethang

Au Nord de la Thaïlande, dans la province de Phrae, une première étude de la sédimentation du réservoir de la Maethang dédié à l’irrigation a eu lieu entre 2004 et 2006, menée par J.-L. Janeau et S. Huon (iEES Paris), leurs étudiants respectifs et leur partenaire thaï du Royal Forest Department. Une nouvelle campagne de […]
