IRD is officially joining the GDR in 2018

The GDR was historically founded by Ifremer and CNRS and enlarged in 2015 to Scotland, Belgium and Crete.

Starting in 2018 the GDRi consortium will receive funding from the IRD (French National Research Institute for Sustainable Development, to support the involvement of African researchers and students working on marine connectivity.


In population biology/genetics, "connectivity" in a metapopulation through the migration of individuals/genes, can be understood as the opposite of the isolation of demes. An enhanced connectivity can reduce the vulnerability of demes through a rescue effect provided by immigration from other demes, reduce the risk of disruption of the metapopulation system, or counter the local effects of genetic drift.

En biologie/génétique des populations, on peut comprendre le terme de "connectivité" d’une métapopulation par le biais de la migration des individus/des gènes, comme l’inverse de l’isolement des dèmes (sous-populations) les uns par rapport aux autres. Une plus grande connectivité peut réduire la vulnérabilité des dèmes à l’extinction par effet secours de l’immigration depuis les autres dèmes, réduire le risque de scission du système de métapopulation, ou encore contrecarrer les effets locaux de la dérive génétique par l’afflux de gènes.
