Description
Summary:International audience Conceived as a baseline for the management and conservation of the marine protected area of the French Southern Territories (réserve naturelle nationale des Terres australes françaises), the checklist of marine macroalgae of the Kerguelen Islands was updated based on an extensive review of the literature and scientific databases, from the first report of the Ross expedition, in 1840, to the most recent works. This work was also conceived as a starting point for forthcoming investigations using molecular systematics tools and for monitoring the effects of global change on sub-Antarctic marine ecosystems. After a brief history of scientific campaigns, a list of 166 species was established (103 Rhodophyta, 35 Chlorophyta and 28 Ochrophyta [Phaeophyceae]). Molecular systematics studiess have shown the existence of recurrent discrepancies between the established, morphology-based taxonomy and molecular species delimitation, calling for a revision of systematics. Nevertheless, a first analysis of biogeographical affinities of the marine flora of the Kerguelen Islands is carried out and preliminary results are partially congruent with the main regions currently recognized in the Southern Ocean suggesting the importance of long-distance dispersal to explain the observed distribution patterns. La végétation marine des îles Kerguelen, inventaire de la flore et première analyse de ses affinités biogéographiques.Conçu comme une base de référence indispensable à la gestion et à la conservation de la flore marine dans l’aire marine protégée des Terres australes françaises (réserve naturelle nationale des Terres australes françaises), l’inventaire de la flore marine des îles Kerguelen a été mis à jour sur la base d’un examen approfondi de la littérature et des bases de données scientifiques, du premier rapport de l’expédition Ross, en 1840, jusqu’aux travaux les plus récents. Ce travail a aussi pour objectif de constituer un point de départ pour de futures investigations utilisant les outils de la ...
