Emergence d'une filière de culture de macro-algues en Bretagne et problème relatif à une espèce non indigène, le wakame (Undaria pinnatifida)
Provedor de dados: 5
Autores: Antoine, Loic; Lemoine, Maud; Boulben, Sylviane; Kaas, Raymond; Laurans, Martial; Viard, Frédérique; Potin, Philippe.
La synthèse de l’expertise collégiale menée par l’Ifremer et la station biologique de Roscoff permet de préconiser le maintien des cultures de Undaria pinnatifida dans les zones déjà mises en culture à condition de se cantonner aux pratiques culturales des exploitants installés depuis longtemps, avec un suivi et sans expérimenter de nouvelles pratiques pour lesquelles il n’y a pas de recul. Là où des essais ont eu lieu en 2010 et 2011 (Projet Chaco), il serait nécessaire de faire rapidement un état des lieux de la présence ou l'absence d'Undaria pinnatifida en milieu naturel afin de mesurer l'impact de ces essais. En l’état actuel des connaissances il n’y a pas de données scientifiques qui permettent de garantir le respect de l’article 24 du R(CE) N°...

Metabarcoding on planktonic larval stages: an efficient approach for detecting and investigating life cycle dynamics of benthic aliens
Provedor de dados: 5

High-throughput sequencing (HTS) technologies offer new promise to support surveillance programs targeting marine non-indigenous species (NIS). Metabarcoding might surpass traditional monitoring methods, for example through its ability to detect rare species, a key feature in early detection of NIS. Another interest of this approach is the identification of organisms difficult to identify based on morphology only (e.g., early developmental stages), making it relevant in the context of management programs. Because many marine benthic NIS have a biphasic benthopelagic life cycle, targeting their pelagic larval stages in zooplankton may allow early detection and assessment of their establishment and potential spread. We illustrate this approach with an...

Human‐mediated transport creates secondary contacts between genetically differentiated lineages, bringing new opportunities for gene exchange. When similar introductions occur in different places, they provide informally replicated experiments for studying hybridisation. We here examined 4,279 Mytilus mussels, sampled in Europe and genotyped with 77 ancestry‐informative markers. We identified a type of introduced mussels, called “dock mussels,” associated with port habitats and displaying a particular genetic signal of admixture between M. edulis and the Mediterranean lineage of M. galloprovincialis. These mussels exhibit similarities in their ancestry compositions, regardless of the local native genetic backgrounds and the distance separating colonised...
