International audience; Mountain watersheds exhibit particularly complex hydrographic networks characterized by both a high spatial and temporal environmental heterogeneity linked to the dynamic of the different water source contributions (glacier and snow meltwater, groundwater, rain). Mountain freshwater ecosystems shelter a singular biodiversity characterized by rare species, often endemic, and display a high spatial variability in aquatic community composition linked to this high level of habitats availability. However, these ecosystems are threatened by the ongoing climate change and associated flow alterations linked to both the accelerated glacier shrinkage and the modification in snow cover. In addition, although mountain regions were historically assimilated to water towers of the surrounding low lands with unlimited water resources; these regions are on the contrary facing unprecedented anthropogenic pressures on the resource, especially due to the current boom in hydropower projects but also the growing water needs of ski resorts for drinking water and artificial snow particularly during low-water periods. These flow alterations induce changes in the hydrological regime at the local scale; but also affect, at the catchment scale, the environmental heterogeneity in habitats and the connectivity of the stream network. These multi-scale alterations might have considerable effects on both the structure and functioning of mountain aquatic ecosystems. In this study, we examined the spatial distribution of aquatic invertebrate communities in two mountain glacierized catchments, with low (3%) and high (30%) glacial influence located respectively in the Andes and the Alps. We sampled benthic invertebrate communities and characterized geographical, physico-chemical and food resource conditions in 51 and 29 stream sites in the Andean and Alpine catchment, respectively. Using both distance decay relationship and variation partitioning analyses, we evaluated the relative contribution of local environmental conditions and spatial processes in structuring the aquatic metacommunity. This study allowed a better understanding of the mechanisms driving the spatial organization of the aquatic communities. This knowledge would permit to develop multi-scale environmental flows in mountains watersheds and management tools to mitigate the impacts of flow alteration and maintain these mountain freshwater ecosystems and their resulting ecosystems services.

International audience; The first internal transcribed spacer (ITS-1) of ribosomal RNA of 5 individuals of unknown pisidiid clams collected over several years in the Rhone river basin was extracted to specify their taxonomic position. The phylogenetic tree obtained from the comparison of these sequences to those of 19 species available in the NCBI genetic database is in good agreement with the phylogenetic structure of Sphaeriinae and revealed that the unknown bivalves belong to the North American species Euglesa compressa. This invasive mollusk has now colonized the major French river basins and could be responsible for the major decline of E. supina in the areas where it has settled. The main features of E. compressa are also presented.

International audience; Co-occurrence of mature larvae and male pharate pupae in benthos samples from the Loire River enabled descriptions of the larva of Homilia leucophaea. Using characters of the head capsule, the labrum, the meso- and metanotum, and the pro- and metathoracic legs, we compared H. leucophaea with larvae of six western European Athripsodes species, including a larval key to these species. The larva of H. leucophaea shares characters with some of the six Athripsodes species. However, without a phylogenetic analysis including larvae, pupae, and adults of Homilia species from the Afrotropical Region, it is currently impossible to decide about a potential synonymy between Athripsodes and Homilia.

International audience; A long-term programme of hydrological and ecological restoration has been conducted on the French Rhone River since 1998. Its main components are i the increase of the minimum flow in the river sections bypassed by an hydro-power plant, ii the direct reconnection of cut-off channels to the river, iii the dredging of isolated pools within the channels. The presentation highlights a selection of key findings from the pre- and post-restoration monitoring of fish and macroinvertebrate assemblages in the River and its floodplain, carried out in four different sectors since 1995.
