Emerging conflict between conservation programmes: when a threatened vertebrate facilitates the dispersal of exotic species in a rare plant community
International audience As an ever-increasing variety of conservation programmes are applied in human-altered environments, there is a growing risk that different conservation actions with conflicting objectives may impede one another. Preventing and resolving the negative impacts of such conflicting...

International audience As an ever-increasing variety of conservation programmes are applied in human-altered environments, there is a growing risk that different conservation actions with conflicting objectives may impede one another.
