Que sait-on aujourd'hui des impacts, positifs et négatifs, de l’agriculture sur la biodiversité ? Quels services la biodiversité peut-elle apporter à l’agriculture, et à quelle hauteur de performance ? Comment favoriser au champ les synergies entre agriculture et biodiversité ? Quels instruments de politiques publics, économiques et juridiques, faut-il mettre en place pour promouvoir ces interactions ? Ces questions ont mobilisé un groupe pluridisciplinaire d’experts (écologues, agronomes, microbiologistes, spécialistes de santé végétale, économistes, juristes, sociologues), de différentes institutions (Inra, CNRS, IRD, Universités, Ecoles supérieures agronomiques) en France et à l’étranger

Disinfection of drain water in greenhouses using a wet condensation heater Inra
Steinberg, C.; Moulin, F.; Gaillard, P.; Gautheron, N.; Stawiecki, K.; Bremeersch, P.; Alabouvette, C..
Une chaudière à condensation classiquement utilisée pour fournir du chauffage et du CO2 dans les serres a été modifiée pour en outre permettre la désinfection des eaux de drainage et leur réintroduction dans la circuit d’irrigation. Différents types de micro-organismes (bactéries, champignons) et des particules virales obtenus soit à partir de cultures pures, soit de substrats de culture (sol, Hortifibre®) ont été introduits dans le circuit de désinfection en amont de la chaudière. Le nombre de micro-organismes survivants dans la solution traitée a été mesuré en sortie de chaudière. Les champignons sont détruits par un passage de 30 s à 58,9°C et la plupart des bactéries testées ne formant pas de spores sont également détruites par un passage de 45 s à...

Fingerprinting methods to approach multitrophic interactions among microflora and microfauna communities in soil Inra
Edel-Hermann, V.; Gautheron, N.; Alabouvette, C.; Steinberg, C..
The soil functioning and the response of the biota to external perturbations such as organic input are based on multitrophic interactions among a wide range of organisms. However, the various components of the soil microflora and microfauna are rarely addressed in ecological studies. We have developed a molecular approach based on terminal restriction fragment length polymorphism (T-RFLP) analysis to assess the community structures of protozoa and nematodes, together with bacteria and fungi that share the same soil environment. Two soils were characterized by a specific fingerprint for each of the four groups of organisms, showing the potential of all T-RFLP procedures to differentiate the community structures. The response of the soil biota to organic...

Mechanisms involved in spatial and temporal mobility of disease patches caused by Rhizoctonia solani in sugar beet field: induction of antagonists within disease patch Inra
Anees, M.; Tronsmo, A.; Edel-Hermann, V.; Gautheron, N.; Faloya, V.; Steinberg, C..
Rhizoctonia solani AG 2-2 causes damping-off and root rot on sugar beet in patches that are highly mobile both on spatial and temporal scales. They never occur in the same place where they were in the previous season. The aim of the present study was to uncover the mechanisms underlying the dynamics of disease patches. It was observed that soil inoculum potential was higher within diseased patch than in healthy area. However, the dormant pathogen in healthy area was stimulated by addition of buckwheat meal more than that in diseased patch. In addition soil from diseased area was more suppressive towards the disease. We did not observe significant differences in bacterial genetic structure with the origin of the soil. However, diseased area could be easily...

Survival and potential denitrifying activity of Azospirillum lipoferum and Bradyrhizobium japonicum inoculated into sterilized soil Inra
Steinberg, C.; Gamard, P.; Faurie, G.; Lensi, R..
Potential denitrifying activity and population dynamics of Azospirillum lipoferum (137C) and Bradyrhizobium japonicum (G2sp) inoculated into a gamma-sterilized soil were studied for a period of 3 weeks. The denitrifying enzyme potential of soil inoculated independently with each bacterial species was strongly stimulated by the presence of a plant (Zea mays L.). Simultaneous inoculation of both bacteria also produced a higher denitrifying enzyme potential than simple inoculation. Even with double inoculation, the presence of a plant did not modify the evolution of the activity. The response of the population dynamics to these treatments followed a different pattern. The population dynamics of A. lipoferum was not affected by the presence of the plant or by...

The Southwest Pacific Ocean circulation and climate experiment (SPICE) ArchiMer
Ganachaud, A.; Cravatte, S.; Melet, A.; Schiller, A.; Holbrook, N. J.; Sloyan, B. M.; Widlansky, M. J.; Bowen, M.; Verron, J.; Wiles, P.; Ridgway, K.; Sutton, P.; Sprintall, J.; Steinberg, C.; Brassington, G.; Cai, W.; Davis, R.; Gasparin, F.; Gourdeau, L.; Hasegawa, T.; Kessler, W.; Maes, C.; Takahashi, K.; Richards, K. J.; Send, U..
The Southwest Pacific Ocean Circulation and Climate Experiment (SPICE) is an international research program under the auspices of CLIVAR. The key objectives are to understand the Southwest Pacific Ocean circulation and the South Pacific Convergence Zone (SPCZ) dynamics, as well as their influence on regional and basin-scale climate patterns. South Pacific thermocline waters are transported in the westward flowing South Equatorial Current (SEC) toward Australia and Papua-New Guinea. On its way, the SEC encounters the numerous islands and straits of the Southwest Pacific and forms boundary currents and jets that eventually redistribute water to the equator and high latitudes. The transit in the Coral, Solomon, and Tasman Seas is of great importance to the...
