| L'analyse des structures dures/calcifiées des organismes aquatiques (poissons, mollusques, cephalopodes...) constitue souvent la base d'études en écologie /biologie des populations et plus particulièrement dans l'étude du fonctionnement des populations. Leur analyse apporte des données telles que l'âge et la croissance, indispensables au développement de modèles en dynamique de populations (stock-recrutement, individus centrés, CMR) et permettent de prendre en compte la variabilité biologique. Ces structures dures sont aussi utilisées pour des caractérisations génétique et environnementale de l'individu. De fait, l'utilisation de ces structures contribue au développement et à la mise en œuvre de méthodes permettant une caractérisation plus précise de... |

| The common sole -Solea solea- is one of the most harvested flatfish population in the Eastern English Channel -EEC; ICES area VIId-. In the EEC, this population is currently assessed and managed as a homogeneous single stock. However, some ecological clues indicate that a metapopulation structure formed by a set of three loosely connected subpopulations associated with local coastal nurseries areas cannot be ruled out. Results show that key estimates of population dynamics parameters, stock assessment and management reference points are highly sensitive to the hypotheses made on the spatial structure. A Bayesian integrated life-cycle model was developed to explore the sensitivity of population dynamics and stock assessment to the level of connectivity in... |

| Anguillid eels were sampled from permanent rivers in the Reunion and Mauritius islands, western Indian Ocean, with a standardized electrofishing method. A. marmorata was very dominant, corresponding to 91.7 and 90.7% of all the eels collected in Reunion and Mauritius, respectively. Three other species (A. mossambica, A. bicolor bicolor and A. nebulosa labiata) were also present in both islands. A. marmorata showed a strong altitudinal gradient of densities from the lower to upper zones, especially in the younger stages (TL < 250 mm), while A. mossambica was only found in the upper zones and A. bicolor bicolor occurred only in the lower zones (A. nebulosa labiata was rare). The eel species composition in freshwaters of both islands is very similar... |
