| In a context of several directives for transitional and coastal waters masses (Water Framework Directive, Marine Strategy Framework Directive and Bathing Water Directive), the good ecological status of water but also conservation of marine ecosystem should be quickly achieved. The Basque coastline (SE of the Bay of Biscay) is subject to strong human pressures with a high density of population over the year, and especially during the summer with tourist activities. It generates nutrient discharge, water and sediment pollution and impacts the quality of the marine environment. Such pressure and the way to reduce its impacts are the main concerns of authorities Locally, in order to improve wastewater treatment process, an alternative technical solution is... |

| Biodiversity conservation and response of benthic communities to pressures, related to global change and human activities, are a research priority. They also constitute a useful indicator to define the environmental status of the Marine Strategy Framework Directive as part of the European Water Framework Directive (WFD). The biogeographic features of the Aquitanian coast (in terms of rocky substrate communities) induce the interest to have a monitoring and research site. Indeed, it includes the habitat characteristics as well as fauna and flora (the Habitats Directive). The aim of the BIGORNO project is to implement new tools to assess the rocky biocenosis in the southern marine subregion of the Bay of Biscay by integrating fauna communities assessment... |

| To determine good ecological status and conservation of the Sub-Marine area of the Bay of Biscay, the implementation of a new rocky intertidal habitats monitoring is needed. A protocol has been adapted from the Brittany protocol for the water body FRFC11 "Basque coast" for the two indicators "intertidal macroalgae" and "subtidal macroalgae" under the Water Framework Directive to qualify the ecological. However no protocol has been validated for fauna in front of meridional characters of the benthic communities. Investigations carried out on macroalgae communities on intertidal area in WFD framework, since 2008, constitute an important working basis. This is the aim of the Bigorno project (Intertidal Biodiversity of the south of the Bay of Biscay and... |

| Hydrothermal vent sites along the Juan de Fuca Ridge in the north-east Pacific host dense populations of Ridgeia piscesae tubeworms that promote habitat heterogeneity and local diversity. A detailed description of the biodiversity and community structure is needed to help understand the ecological processes that underlie the distribution and dynamics of deep-sea vent communities. Here, we assessed the composition, abundance, diversity and trophic structure of six tubeworm samples, corresponding to different successional stages, collected on the Grotto hydrothermal edifice (Main Endeavour Field, Juan de Fuca Ridge) at 2196 m depth. Including R. piscesae, a total of 36 macrofaunal taxa were identified to the species level. Although polychaetes made up the... |
