IRD UR 103
The microbiology team of the UR103 is qualified in the study of microbial trophic networks (biomass, flow, controls), of interactions with the dynamics of particulate material, and of modifications under the influence of physical forcing and the contributions anthropogenic (nutrients, metals). In recent years, due in particular to collaborations with the UMR 5119 and 5254, it has been able to extend the evaluation of the effect of the anthropogenic inputs to the structure of the bacterial communities thus further developing the study of the these impacts on biomass, flows and processes. It has the majority of the equipment necessary to the study. The physics team of the UR103 studies the mechanisms of water mass circulation and particulate transport on the basis of integrated approach associating: measurements of ground, space observation, and numerical modeling. The members of team have worked in various estuarine (in Guyana and the Mediterranean) and coastal tropical (New Caledonia, Cuba, Fiji) systems. The UR103 has a good experiment of the logistic organization of multi-disciplinary measurements in situations distant from large infrastructures of research (New Caledonia, Cuba, Fiji).

IRD UR 167
The UR 167 aims to understand the ecology of cyanobacteria of the tropical aquatic environments. These prokaryotic organizations colonize the majority of marine and continental water and play an important role in aquatic ecosystems. The team studies the competition between bacteria and phytoplankton (in particular cyanobacteria) for the nutrients, as well as the predator- prey interactions within the microbial network and the zooplankton. In order to better understand the relationships between the biotic and abiotic environment, cyanobacteria, and their organizations candidates or predators within the microbial network, the UR 167 develops tools and a know-how in the field of tropical microbial ecology.

UMR 5119 (Montpellier 2 University)
The UMR 5119 includes a team working on the structure and the functioning of the microbial food webs (viruses, bacteria, phytoplankton, protozoa). This team has an expertise in: (I) the study of the factors of regulation of diversity and the functioning of bacterioplankton in the aquatic environments, (II) the study of the structure of phytoplankton and its influence on the trophic networks and the biogeochemical cycles, (III) the sanitary impact of the anthropogenic inputs in the coastal marine ecosystems. The team is leader of several national and international projects, in particular on 1) the spatial dynamics of phylogenetic and physiological diversity bacterial 2) the effect of viruses on the control of bacterial diversity and 3) the influence of the environmental modifications of anthropogenic origin, for example those related to the global changes, on the structure of the phytoplankton and their effects on the functioning of pelagic food webs. This research is multi-disciplinary and combines multiple approaches: molecular, biogeochemical (i.e. pigmentary biomarkers), optics (i.e. flow cytometry) to determine the mechanisms of coexistence of species and/or groups, and their factors of control.Mail: This e-mail address is being protected from spam bots, you need JavaScript enabled to view it More details..
UMR 5254 (Université de Pau et des Pays de l’Adour)
Within the IPREM (Multi-disciplinary Institute of Research in Environment and Materials), the teams EM (Environment and microbiology) and CABIE (Analytical Chemistry, Inorganic Bio and Environment) collaborate closely in order to understand the role of the micro-organisms in the ecodynamics of the metal contaminants. The complementarity of competences of the two teams at the same time in analytical chemistry and microbial ecology makes it possible to apprehend in an integrated way these problems, in particular by developing new and powerful tools for chemical analyzes (chemical speciation, detection of the trace elements and isotopic tracers) and microbiological analyzes (analyzes of bacterial communities by genomic and transcriptomic approaches). Thus the biogeochemical cycles of the trace elements in general and in particular, mercury, are studied by these integrated approaches so as to (1) evaluate the impact of metals on the microbial communities, (2) estimate the role of the micro-organisms on the fate of metals and (3) to understand the adaptation processes of the bacteria to the presence of the metallic compounds. To achieve these specific goals, the studies are driven at various levels of biological organization: (A) at the level of the ecosystems and the communities by in situ studies, (b) at the level of the population by incubations in microcosms and the isolation of bacterial strains, and (c) at the cellular and molecular level by biochemical, physiological and molecular approaches.Mail: This e-mail address is being protected from spam bots, you need JavaScript enabled to view it More details..
Institute of Marine Environment and Resources (IMER)
With the participation of 3 of its departments (physics, chemistry of the environment, plankton) in the project, the IMER brings essential competences in modeling of the hydrodynamics and particulate transport, in the analysis of a great number of contaminants (organo-phosphorates, organochlorinates, organo-tins, metals…), and in the study of phytoplankton (taxonomy, insulation and culture) and of bacteria (insulation, cultures). The IMER has a solid experience of international co-operation, has the majority of the equipment necessary to carry out these analyzes, and will accommodate the researchers on mission in its laboratories with the IMER (Haiphong) and its marine station.
