| In order to study further the genetic structure of the pearl oyster Pinctada margaritifera in French Polynesia with a special consideration for the sampling scale, we analyzed or re-analyzed sets of data based on nuclear DNA markers obtained at different spatial scales. At a large scale (several 1,000 km), the remote Marquesas Islands were confirmed to be significantly differentiated from Tuamotu-Gambier and Society archipelagos, with a marked difference however for the two main islands that are different from each other. At a medium scale (several 10 to several 100 km), overall homogeneity was observed within and between these two archipelagos, with some exceptions. This could be attributed both to large-scale larval dispersal and to human-driven spat... |

| Habitat connectivity is central to several key evolutionary and ecological processes, having implications for the spatial structuring of marine populations. For benthic species that have no or little mobility as adults, connectivity is evaluated by analyzing the dispersal of propagules across the seascape. We investigate fine-scale connectivity of coralligenous habitats in Marseille Bay (located in the north-western Mediterranean) sea using high-resolution cartography and a particle-tracking model ran over a range of parameters derived from the biological traits of potential target species. We present annual and seasonal means of various connectivity diagnostics measuring the retention and exchange of propagules among coralligenous patches. A synthetic... |

| Resumo: O uso de coletores de substrato artificial para o biomonitoramento da qualidade da água na aquicultura se apresenta como uma tecnologia de monitoramento viável para seu emprego por produtores, uma vez que utiliza material de baixo custo e de fácil confecção, instalação e manuseio. Ademais, a identificação dos organismos bentônicos por meio de ilustrações permi- te, de uma maneira fácil e objetiva, inferir sobre a qualidade da água com base na sensibilidade de cada organismo à poluição. |
