Next Generation Biomonitoring of change in ecosystems structure and function
Next Generation Biomonitoring of change in ecosystems structure and function
- Coordination: David A. Bohan (INRA, Agroécologie): project leader; C. Vacher (INRA, Biogeco): contact for the work on foliar microbiota
- Partners: Cirad PVBMT, Department of Computing, Imperial College London, INRA MIA, INRA Agroécologie, INRA BIOGECO, INRA IGEPP, CNRS EEP, CNRS CEFE, INRA UE Forêt-Pierroton
- Goals: The NGB project aims at reconstructing species interaction networks to identify change in ecosystem properties, using a combination of NGS and Machine Learning. On ORPHEE, irrigated and non-irrigated plots will be used to investigate the potential of leaf microbial community to predict drought stress status of forest trees.

Tree diversity effects on soil microbes (2017-2018)
Tree diversity effects on soil microbes (2017-2018)
- Coordination : Alison Munson, Manuella Strukelj
- Partners : University of Laval (Québec, Canada), University of Bordeaux
- Goals : Our study will characterize how tree species richness and manipulated water availability affect the functional and structural diversity of soil microbial communities and soil carbon and nitrogen pools. Mineral soil (0-10 cm) was sampled in february 2017 and will be analyzed by the Microresp method to assess functional diversity of microbial community and by Phospholipid fatty acid analysis (PLFA) for its structural diversity. We expected that increase in species richness and precipitations will increase microbial diversity, activity and soil carbon and nitrogen concentrations.

Diversity and Productivity of Trees: effects of biotic Interactions under Climatic Constraint
Diversity and Productivity of Trees: effects of biotic Interactions under Climatic Constraint
- Coordination: Hervé Jactel (INRA, BIOGECO)
- Partners: INRA BIOGECO, INRA UE Forêt-Pierroton, INRA EEF, INRA ISPA, CNRS CEFE
- Goals: The projetcts aims to understanding the mechanisms responsible for drought and tree diversity interactive effects on tree productivity. In particular, we are intergrating aboveground processes and belowground processes by focusing on tree diversity on light and microclimate, on herbivorous insects and on litter and root decomposition.

Biodiversity and Productivity of forests: effects of biotic interactions under Climatic Constraints
- Coordination: Bastien Castagneyrol (INRA, BIOGECO)
- Partners: INRA BIOGECO, INRA UE Forêt-Pierroton, INRA EEF, CNRS CEFE, CRPF Aquitaine
- Goals: The projetcts aims to understanding the mechanisms responsible for drought and tree diversity interactive effects on tree productivity. In particular, we are addressing the indirect effects of tree diversity on productivity through changes in biotic interactions among understorey vegetation, trees, herbivores and predators.

About herbivores
About herbivores
We are currently taking part in a project on insect herbivores aiming to test the interactive effects of tree diversity and climate in insect herbivory. Bastien Castagneyrol (INRA) is coordinating this project.
About predators
About predators
Evalyne W. Muiruri (University of Durham) is currently analysing predation data collected in 2016 on several TreeDivNet sites, including ORPHEE
About litter decomposition
About litter decomposition
Tea bags were burried in ORPHEE plots in 2016. Some were taken out, some are still there.
