Génomique de l'adaptation de l'huître creuse du Pacifique, Crassostrea gigas, dans le cadre de son expansion géographique
Provedor de dados: 5
Autores: Rohfritsch, Audrey; Bierne, Nicolas; Boudry, Pierre; Heurtebise, Serge; Lapegue, Sylvie.
Originating from the north eastern Asia, Crassostrea gigas has been introduced and translocated, mainly for aquaculture purpose, into several European countries (from Norway to Portugal and in the Mediterranean Sea) (1). Although highly variable, the invasiveness pattern of C. gigas has been demonstrated in several countries and therefore considered as a pest or a noxious species in those areas (2 and 3).  Our project aims at identifying the characteristics of such a flourishing species: can its success be explained by chance and/or global warming only or does it exhibit a more important potential of adaptation than other species? Therefore we developed a population genomics approach, known as "genome scan". It corresponds to the study of numerous loci...

Génomique de l'adaptation de l'huître creuse, Crassostrea gigas, dans le contexte de sa récente expansion géographique en Europe
Provedor de dados: 5
Autores: Rohfritsch, Audrey; Bierne, Nicolas; Boudry, Pierre; Heurtebise, Serge; Cornette, Florence; Lapegue, Sylvie.
Originaire du nord de l’Asie, l'huître creuse, Crassostrea gigas, a été introduite et transférée, principalement pour l’aquaculture, dans plusieurs pays européens depuis le début des années 1970. Le caractère invasif de cette espèce a été observé au cours de la dernière décennie dans plusieurs pays et elle a même été considérée comme une espèce nuisible dans certaines régions, telles que la mer de Wadden. Dans le cadre du projet HiFlo, soutenu par l’ANR, nous avons pour objectif d'identifier les caractéristiques d'une telle espèce florissante: son succès peut-il être expliqué par le hasard des opportunités (expansion de leur niche écologique) ou est-il lié à des processus évolutifs, ce qui impliquerait une adaptation génétique de l'espèce à de nouvelles...

Population genomics shed light on the demographic and adaptive histories of European invasion in the Pacific oyster, Crassostrea gigas
Provedor de dados: 5
Autores: Rohfritsch, Audrey; Bierne, Nicolas; Boudry, Pierre; Heurtebise, Serge; Cornette, Florence; Lapegue, Sylvie.
Crassostrea gigas originated from the Pacific coast of Asia, but was introduced into several European countries in the early 1970s. Natural populations have now spread across the length of the western seaboard of Europe. To elucidate the demographic and selective processes at play during this rapid expansion, genome-scan analysis was performed on different populations. High diversities and low differentiation were observed overall, but significant genetic differentiation was found among newly established populations and between the newly established northern group and a nearly panmictic group composed of southern European populations and a population from Japan. Loss of genetic diversity was also seen in the north, likely caused by founder events during...
