Última Species are hypotheses: avoid connectivity assessments based on pillars of sand ArchiMer Pante, Eric; Puillandre, Nicolas; Viricel, Amélia; Arnaud-haond, Sophie; Aurelle, Didier; Castelin, Magalie; Chenuil, Anne; Destombe, Christophe; Forcioli, Didier; Valero, Myriam; Viard, Frederique; Samadi, Sarah. Connectivity among populations determines the dynamics and evolution of populations, and its assessment is essential in ecology in general and in conservation biology in particular. The robust basis of any ecological study is the accurate delimitation of evolutionary units, such as populations, metapopulations and species. Yet a disconnect still persists between the work of taxonomists describing species as working hypotheses and the use of species delimitation by molecular ecologists interested in describing patterns of gene flow. This problem is particularly acute in the marine environment where the inventory of biodiversity is relatively delayed, while for the past two decades, molecular studies have shown a high prevalence of cryptic species.

J. Martinez; Boillot, C.; Munaron, Dominique; Fenet, H.; Casellas, C.; Gomez, E.. Coastal areas are subject to growing pressures and impacts due to increasing of the human activities. Lipophilic organic contaminants, such as polycyclic aromatic hydrocarbons (PAHs) or polychlorinated biphenyls (PCBs), have been monitored for decades within biomonitoring programs. However, until now, little information on the detection of called “emerging contaminants” as hydrophilic organic compounds, in the marine environment and no data on its metabolites or transformation products in marine organisms is available. In this way, a sensitive analytical methodology for identification and confirmation of venlafaxine residues (VEN) and five of its main metabolites in the marine mussels Mytilus galloprovincialis was validated.

Application aux organismes marins ArchiMer Thibaud, Yves. The author presents an analysis technique permitting the determination of the tin in the tissues of marine organisms. This technique is only the application of the spectrophotometry of atomic absorption with atomization in the electrothermic oven. After the acid attack of the sample, the solution is put in a graphite oven to atomize the tin selectively and quantitatively. The detection limit obtained, 0,5 mu g/g of the lyophilized flesh is very satisfactory, to show the purport variations in shells from different origins.

Ano: 1980 URL: http://archimer.ifremer.fr/doc/1980/publication-1906.pdf Contamination chimique du milieu marin : de la mesure à l'évaluation des risques ArchiMer Abarnou, Alain. This activity report entitled (“Chemical contamination of the marine environment: from measurement to risk assessment”) summarizes the main stages my career at Ifremer from November 1975 to june 2013. The first chapter deals with the seawater chlorination and chlorinated waters released into the sea, the identification and the conditions of the formation of various by-product of these processes. The second chapter concerns PCBs, their nature, their chemical analysis in environmental matrices. PCBs are considered as the best examples of persistant and bioaccumulable compounds and therefore, in all this report they are flagship contaminants to which other groups of studied substances are compared. The third chapter refers to studies performed within marine...

Marine plastic pollution is a major environmental issue. Given their ubiquitous nature and small dimensions, ingestion of microplastic (MP) and nanoplastic (NP) particles and their subsequent impact on marine life are a growing concern worldwide. Transfers along the trophic chain, including possible translocation, for which the hazards are less understood, are also a major preoccupation. Effects of MP ingestion have been studied on animals through laboratory exposure, showing impacts on feeding activity, reserve depletion and inflammatory responses, with consequences for fitness, notably reproduction. However, most experimental studies have used doses of manufactured virgin microspheres that may not be environmentally realistic. As for most...

Because of their characteristic living environments, marine organisms produce a variety of lipids. Fatty acids constitute the essential part of triglycerides and wax esters, which are the major components of fats and oils. Nevertheless, phospholipids and glycolipids have considerable importance and will be taken into account, especially the latter compounds that excite increasing interest regarding their promising biological activities. Thus, in addition to the major polyunsaturated fatty acids (PUFA) such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, a great number of various fatty acids occur in marine organisms, e.g. saturated, mono- and diunsaturated, branched, halogenated, hydroxylated, methoxylated, non-methylene-interrupted.

Ano: 2005 URL: http://archimer.ifremer.fr/doc/2005/publication-937.pdf Harmful or harmless: biological effects of marennine on marine organisms ArchiMer Falaise, Charlotte; Cormier, Patrick; Tremblay, Réjean; Audet, Céline; Deschênes, Jean-sébastien; Turcotte, François; François, Cyrille; Seger, Andreas; Hallegraeff, Gustaaf; Lindquist, Niels; Sirjacobs, Damien; Gobert, Sylvie; Lejeune, Pierre; Demoulin, Vincent; Mouget, Jean-luc. Marennine is a water-soluble blue-green pigment produced by the marine diatom Haslea ostrearia. The diatom and its pigment are well known from oyster farming areas as the source of the greening of oyster gills, a natural process increasing their market value in Western France. Blooms of blue Haslea are also present outside oyster ponds and hence marine organisms can be exposed, periodically and locally, to significant amounts of marennine in natural environments. Due to its demonstrated antibacterial activities against marine pathogenic bacteria (e.g. Vibrio) and possible prophylactic effects toward bivalve larvae, marennine is of special interest for the aquaculture industry, especially bivalve hatcheries. The present study aimed to provide new insights... Tipo: Text Palavras-chave: Diatom; Haslea ostrearia; Marennine; Marine organisms; Natural bioactive compound.

Durante la incidencia de los frentes fríos de cualquier intensidad en toda la Ensenada de Sibarimar, el movimiento neto del agua sigue el contorno del litoral costero E-W. La circulación marina, además, mantiene fluctuaciones en la dirección perpendicular a la del movimiento medio. Las velocidades máximas de la corriente son altas entre 100-200 cm/s. En condiciones de régimen habitual, la traslación más rápida de los organismos, en dirección paralela a la costa, ocurre desde Guardafronteras hasta Calle 476-478, recorriendo 7 m en 2 min. Durante la acción de frentes fríos, ya sean débiles, moderados o intensos toda la costa será afectada por la deriva, ocurriendo la mayor recala de organismos hacia el W de la Ensenada de Sibarimar.
