[null,null,null,"Sommario/riassunto","La communauté internationale prétend freiner la perte de biodiversité et maintenir les services rendus par les écosystèmes. Ces termes à la mode expriment-ils une nouvelle façon de concevoir la nature ? L’auteur analyse l’évolution des idées depuis le début du xxe siècle, où l’on se préoccupait de protéger la nature, jusqu’à nos jours, où il est question de gérer la biodiversité. Les bouleversements récents dans la façon dont les sciences appréhendent la nature mettent en évidence un renouvellement de paradigme. L’idée d’équilibre naturel a longtemps prévalu en écologie. Aujourd’hui, s’impose celle de changement permanent, qui appelle une réflexion éthique : comment repenser les valeurs qui fondent les relations homme-nature, sachant que la biodiversité s’inscrit dans une trajectoire ?  Dans un contexte marqué par de nouveaux repères conceptuels et par l’urgence des prises de "]
[{"$nulls":4},"décision, les scientifiques se trouvent de plus en plus impliqués dans la mise en oeuvre de projets qui inscrivent une biodiversité « choisie » dans leurs objectifs. L’auteur ouvre la réflexion sur l’évolution qui en résulte nécessairement dans la pratique du métier de chercheur."]
