Coastal ecosystems provide a wide range of valuable ecosystem services (ES) for human wellbeing. Such services depend on the functioning and structure of ecosystems. Unfortunately, these ecosystems are threatened by humans, directly impairing their ability to provide these services. In order to predict such changes, we used a food web model to fore...
Though the morphological discrimination of the three pseudo-cryptic Ammonia species, A. aberdoveyensis , A. confertitesta and A. veneta , has been recently established, information on their ecology and habitats are still relatively scarce. This study aims to define distribution patterns of these species at eight sites scattered along the French coa...
The suprabenthos corresponds to organisms that migrate at night in the lower water layers and are in the sediment during the day. Among the suprabenthic peracarids, amphipods were frequently the most diversified while mysids were the most abundant group. During two-years of study of the prawn Palaemon serratus larvae, to state of the complete cycle...
The erosion of biodiversity and marine diversity is biased because it is based mainly on vertebrates from tropical or island areas; it does not apply to marine invertebrates. The invertebrate diversity is high in the English Channel, and increases according to new studies and the voluntary or involuntary introductions of non-native species. The ben...
