Disturbance induced decoupling between host genetics and composition of the associated microbiome ArchiMer
Wegner, Karl Mathias; Volkenborn, Nils; Peter, Hannes; Eiler, Alexander.
Background Studies of oyster microbiomes have revealed that a limited number of microbes, including pathogens, can dominate microbial communities in host tissues such as gills and gut. Much of the bacterial diversity however remains underexplored and unexplained, although environmental conditions and host genetics have been implicated. We used 454 next generation 16S rRNA amplicon sequencing of individually tagged PCR reactions to explore the diversity of bacterial communities in gill tissue of the invasive Pacific oyster Crassostrea gigas stemming from genetically differentiated beds under ambient outdoor conditions and after a multifaceted disturbance treatment imposing stress on the host. Results While the gill associated microbial communities in...

Sustainable large‐scale production of European flat oyster ( Ostrea edulis ) seed for ecological restoration and aquaculture: a review ArchiMer
Colsoul, Bérenger; Boudry, Pierre; Pérez‐parallé, María Luz; Bratoš Cetinić, Ana; Hugh‐jones, Tristan; Arzul, Isabelle; Mérou, Nicolas; Wegner, Karl Mathias; Peter, Corina; Merk, Verena; Pogoda, Bernadette.
The conservation and active restoration of European flat oyster (Ostrea edulis) populations are a major focus of ecological restoration efforts to take advantage of the wide‐ranging ecosystem functions and services this species provides. Accordingly, additional and new demands for seed oysters have arisen. In commercial aquaculture (mariculture), the production of O. edulis is still largely based on natural seed collection. Considering the specific requirements, related to ecological restoration, such as the absence of pathogens and the preservation of high genetic diversity, the current supply is insufficient. Despite the development of breeding and controlled reproduction techniques for this species since the late 1930s, seed production today is mainly...
