Última Barriers in the pelagic: population structuring of Calanus helgolandicus and C. euxinus in European waters Naturalis Yebra, L.; Bonnet, D.; Harris, R.P.; Lindeque, P.K.; Peijnenburg, K.T.C.A.. Molecular studies of marine plankton have shown that ecological and/or environmental barriers play an important role in separating populations. Calanoid copepods are central in marine ecosystems, and dramatic biogeographical shifts in copepod assemblages associated with recent climate warming have been reported. We examined spatial population structuring in European waters of the Atlantic Ocean and Mediterranean Sea of Calanus helgolandicus and its sister species, C. euxi nus, from the Black Sea based on genetic and morphometric characters. The aims were to identify barriers to dispersal, relate these to hydrographic characteristics and infer historical patterns of distribution and demography. We analysed a 408 bp fragment of the mitochondrial 16S gene...

Ano: 2011 URL: http://www.repository.naturalis.nl/record/470574 Contribution to the understanding of the cycle of the protozoan parasite Marteilia refringens ArchiMer Arzul, Isabelle; Chollet, Bruno; Boyer, S.; Bonnet, D.; Gaillard, Juliette; Baldi, Yoann; Robert, Maeva; Joly, Jean-pierre; Garcia, Celine; Bouchoucha, Marc. The paramyxean parasite Marteilia refringens infects several bivalve species including European flat oysters Ostrea edulis and Mediterranean mussels Mytilus galloprovincialis. Sequence polymorphism allowed definition of three parasite types ‘M’, ‘O’ and ‘C’ preferably detected in oysters, mussels and cockles respectively.Transmission of the infection from infected bivalves to copepods Paracartia grani could be experimentally achieved but assays fromcopepods to bivalves failed. In order to contribute to the elucidation of the M. refringens life cycle, the dynamics of the infection was investigated in O. edulis, M. galloprovincialis and zooplankton over one year in Diana lagoon, Corsica (France). Flat oysters appeared non-infected while mussels were infected... Tipo: Text Palavras-chave: Bivalves; Marteilia refringens; Copepods; Paracartia latisetosa; Zooplankton; Parasite life cycle. Ano: 2014 URL: http://archimer.ifremer.fr/doc/00165/27635/25768.pdf New evidence for the involvement of Paracartia grani (Copepoda, Calanoida) in the life cycle of Marteilia refringens (Paramyxea) ArchiMer Boyer, S.; Chollet, Bruno; Bonnet, D.; Arzul, Isabelle. The dynamics of the protozoan parasite Marteilia refringens was studied in Thau lagoon, an important French shellfish site, for 1 year in three potential hosts: the Mediterranean mussel Mytilus galloprovincialis (Mytiliidae) the grooved carpet shell Ruditapes decussatus (Veneriidae) and the copepod Paracartia grani (Acartiidae). Parasite DNA was detected by PCR in R. decussatus. In situ hybridisation showed necrotic cells of M. refringens in the digestive epithelia of some R. decussatus suggesting the non-involvement of this species in the parasite life cycle. In contrast, the detection of M. refringens in mussels using PCR appeared bimodal with two peaks in spring and autumn. Histological observations of PCR-positive mussels revealed the presence of...
