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

Impact of abundance weighting on the response of seed traits to climate and land use Inra
Pakeman, R.J.; Garnier, E.; Lavorel, S.; Ansquer, P.; Castro, H.; Cruz, P.; Dolezal, J.; Eriksson, O.; Freitas, H.; Golodets, C.; Kigel, J.; Kleyer, M.; Leps, J.; Meier, T.; Papadimitriou, M.; Papanastasis, V.P.; Quested, H.; Quétier, F.; Rusch, G.; Sternberg, M.; Theau, J.P.; Thébault, A.; Vile, D..
Many studies have identified relationships between plant reproductive behaviour and environmental conditions. However, they have all been based on cross-species analysis and take no account of the relative abundance of species with vegetation. 2.Using two reproductive traits – seed mass and dispersal vector – as examples, a range of previously identified relationships were tested using both unweighted and weighted-by-abundance data collected from land-use transitions at 12 sites across Europe. 3.Seed mass was correlated positively with most measures of temperature (stronger relationships for unweighted data) and declined against measures of disturbance (stronger relationships with weighted data). It was not related consistently to measures of water...

Leaf traits capture the effects of land use changes and climate on litter decomposability of grasslands across Europe Inra
Fortunel, C.; Garnier, E.; Joffre, R.; Kazakou, E.; Quested, H.; Grigulis, K.; Lavorel, S.; Ansquer, P.; Castro, H.; Cruz, P.; Dolezal, J.; Eriksson, O.; Freitas, H.; Golodets, C.; Jouany, C.; Kigel, J.; Kleyer, M.; Lehsten, V.; Leps, J.; Meier, T.; Pakeman, R.; Papadimitriou, M.; Papanastasis, V.P.; Quétier, F.; Robson, M.; Sternberg, M.; Theau, J.P.; Thebault, A.; Zarovali, M..
Land use and climate changes induce shifts in plant functional diversity and community structure, thereby modifying ecosystem processes. This is particularly true for litter decomposition, an essential process in the biogeochemical cycles of carbon and nutrients. In this study, we asked whether changes in functional traits of living leaves in response to changes in land use and climate were related to rates of litter potential decomposition, hereafter denoted litter decomposability, across a range of 10 contrasting sites. To disentangle the different control factors on litter decomposition, we conducted a microcosm experiment to determine the decomposability under standard conditions of litters collected in herbaceous communities from Europe and Israel. We...
