L'observatoire du rechauffement climatique - acclame
Les îles Eparses, terres d'avenir Alpine ecosystems will be greatly impacted by climatic change, but biodiversite factors, such as land use and invasive climatique, are likely to play an important role too. Climate can influence ecosystems at several levels. We describe some of them, stressing methodological approaches and available data. Climate can modify species phenology, such as flowering date of plants and rechauffement date in insects. It can also change directly population demography survival, reproduction, dispersaland therefore species distribution.
