Full text"Income breeder", the Northern shoveler Spatula clypeata makes several stopovers between its wintering and breeding site in order to replenish its reserves and complete its pre-breeding migration. Freshwater invertebrates are the main prey of the Northern shoveler and are captured mainly by filtration. This research project had three main objectives: (1) to understand the abundance, diversity, and habitat of freshwater invertebrates in two wetlands known for their high abundance of Northern shoveler, the Marais breton, and the Marais poitevin; (2) to study the environmental and nutrient characteristics of the habitats used by the Northern shoveler during its prenuptial stopover; (3) to define habitat management measures in favour of all of the species groups studied. This study showed that the ponds studied were abundant in freshwater invertebrates. The study defined four habitat typologies based on environmental variables and the presence of some key invertebrate taxa. During migratory stopover, the Northern shoveler used different habitats with a nychthemeral rhythm. Daytime sites were deep and sparsely vegetated habitats dominated by microcrustaceans, while nighttime sites were shallow and vegetated habitats with high invertebrate taxonomic diversity. Home range sizes did not differ between the two wetlands, between sexes or between age classes (juveniles and adults). Finally, this study revealed that during the prenuptial stopover, the Northern shoveler fed mainly on Cladocera, Copepoda, Chironomidae larvae, Pleidae and Particulate Organic Matter. The results of this work could help to define management and habitat conservation measures for all the species studied

Full textFrom November 2002 to December 2005, the preferential habitat of the indigenous white-clawed crayfish (Austropotamobius pallipes) was determined in the “Pays de Gâtine” (Deux-Sèvres, France). For this study, eight brooks, from four different catchments, were selected. Two sampling sites were monitored per brook; the first being where the population was present and the second 2 to 3 km downstream of the population. Twenty-three physico-chemical parameters, concerning both mineral and organic water components, were regularly measured as well as four samplings of benthic macroinvertebrate fauna. This study made it possible to build up a large data base characterizing the tolerance levels of A. Pallipes with respect to certain parameters, which led us to discuss its status as a bioindicator of water quality. The use of multivariate analysis (mainly Principal Component Analysis) showed (i) that organic matter seems to discriminate A. Pallipes presence/absence and (ii) that A. Pallipes presence is closely associated with the occurrence of some families of macroinvertebrates which are very sensitive to organic pollution. PCA also permitted us to considerably reduce the number of abiotic and biotic parameters considered. In addition, the use of these selected parameters to model A. Pallipes presence/absence with Artificial Neural Networks (ANN) showed interesting and promising results for the management and the conservation of this threatened species

Full textThe aquatic biocenoses of the Arc stream, a coastal Mediterranean stream, were investigated to assess the impact of the water enrichment on the communities'trophic and taxonomic structures. The benthic macroinvertebrates communities, the chironomid communities and the epilithon were studied for this purpose. At first, the acroinvertebrates communities were studied in the main stem and in different pristine tributaries to consider the role of these tributaries in the maintenance of the macroinvertebrates biodiversity at the catchment scale. Then the chironomid communities were investigated using the pupal exuviae assemblages to assess changes in the chironomid communities' trophic and taxonomic structures along a water enrichment gradient. At the riffle scale, correlations were found between the epilithic algal structure and the chironomid larvae distribution; and the guts content analysis of Eukiefferiella claripennis revealed the foraging behaviour of such opportunistic taxa and helped to understand how this taxa spread under such conditions. All these approaches allowed us to assemble clues for understanding changes occurring in such enriched streams at different scales, going from the epilithic algae to the whole macroinvertebrate community

Full textThe analysis of a large number of published works describing biodiversity at local scales allowed us to identify 1093 species of benthic invertebrates from 631 sampling sites in the Adour-Garonne stream system (South-Western France). Macroinvertebrate distribution revealed spatial patterns in species assemblages from which we derived stream classifications. These classifications showed altitudinal and geographic differences in the specific composition of invertebrate communities reflecting the various physiographical situations encountered by streams at a regional scale. They also provide a useful framework for studying and managing streams in large geographic areas. In an economically developed area, water is a useful resource for many human activities. Macroinvertebrate communities are very sensitive to human modifications on streams and the surrounding land. These modifications induce changes in "natural" spatial patterns of specific and functional diversity. The EU Water framework directive adopted in 2000 (2000/60/EC) defines goals for management and protection of European surface waters in the next years. It clearly states that the best model for a single system of water management is management by river basin. Our work suggest that the understanding of aquatic ecosystems at a river basin scale necessarily relies on the analysis of a large number of local studies, the origin of which is generally diverse. It also emphasized the significance of geographic information systems to compile and organize biotic and abiotic data and make them exploitable through adapted multivariate analysis techniques

Full textIn freshwater ecosystems, sediments act as an accumulation compartment for metallic pollutants as uranium. Secondary, there can also represent endogenous sources of contamination by resuspension (e. G. Flood, bioturbation) or changes of metal speciation that acts upon their bioavailability. Indeed, metallic compounds can be transformed in more or less toxic or inert compounds through physico-chemical (e. G. PH, redox conditions, ionic force) and microbiological variations. These conditions are themselves under the effects of benthic macro-invertebrate activities via bioturbation processes. The main objective of this PhD was to determinate the influence of two benthic macroinvertebrate species (Chironomus riparius and Tubifex tubifex) on the distribution and the transfers of uranium within freshwater sediments. To reach this goal, laboratory experiments were performed in order to (i) assess the effects of uranium on benthic macroinvertebrates, more particularly on their bioturbation activity, (ii) determine the influence of these organisms on uranium behaviour through high resolution physico-chemical measurements (e. G. Oxygen optodes, DET gel probes), and (iii) estimate the consequences of these interactions on pelagic organisms via genotoxicity measurements (micronuclei assay and molecular biomarkers analysis on Xenopus laevis). The results demonstrate that bioturbation intensity of macroinvertebrates can be affected in uranium-contaminated sediments, but the two species studied in this work show a relative tolerance. For high uranium concentrations (>100 times the geochemical background level), corresponding however to realistic concentrations in highly contaminated sites, T. Tubifex worms are able to maintain a sufficient bioturbation activity that induces a high remobilization of uranium initially associated with sediments to the overlying water (factor 2 to 10). That represents therefore a potential risk for the remaining aquatic biocenosis. However, by testing this assumption on X. Laevis, it was surprisingly noticed that the worms’ behaviour can be modified in presence of this organism in the water column. The effect of bioturbation on uranium release from the sediments was thus altered conducing to lower uranium concentrations in the water column. Nevertheless, sediment-associated uranium, without the effect of bioturbation, induces negative effects on this pelagic organism. Finally, this PhD work illustrates the interactions that can exist between aquatic organisms, sediment biogeochemistry and a metallic pollutant as uranium. The novel results obtained permit to view more precisely the consequences of uranium pollution in aquatic environment. More globally, this work will contribute to a better assessment of ecological risks in polluted aquatic ecosystems

Full textThe European Water Framework Directive (WFD) aims to achieve a rapid improvement of the water quality, in each member state, and to achieve good ecological status of rivers by 2015. This new directive implies not only to assess the degree of pollution but also to define an ecological state of the environment in relation to a reference condition. This has prompted a large amount of works which yielded characterizations of both reference physical-chemical environments and biological communities in continental Europe, as well as practical tools (e. G. , biological indices) to evaluate water quality. Although geographically distant the continent, DOMs are an integral part of the European Union and are subject to the same objectives and obligations in terms of environmental policies. French Guiana (FG) is an overseas region of France located on the north-eastern coast of South America. The Guianese primary forest remains one of the least impacted of the World, however, gold mining and timber have strong localized impacts upon river ecosystems. Small streams (from headwaters to rivers with depth inferior to 1 meter and width inferior to10 meters) represent 70-80% of all running waters in FG. Most small streams are located in forested areas and exhibit high ecological quality; some if not most of them have never been impacted by any human activity. The main objective of this thesis was to design a biotic index to assess the ecological quality of small streams of FG. We first analysed the effects of disturbance on the physical-chemical quality of ecosystems. Then, we brought out the first typology of community structure in relation to environmental conditions. The identification of the sub-ecological regions and the references conditions allowed us to build a first multi-metric. Finally, a functional approach based on Ephemeroptera was used in order to provide new information on the ecology of this important order of macroinvertebrates. We first demonstrated that physical variables describing the river bottom, and suspended solids discriminate gold-mined from reference sites, while, whatever the type of impact encountered, nutrient concentrations do not prove relevant to measure human impacts. The bio-typology showed that sites characterized by invertebrate communities clustered into two major subsets: the coastal alluvial plain and the Guiana Shield. Changes in community composition, and to a lesser extent taxonomic richness within each sub region revealed ecological impacts of gold mining and logging. Among the biological metrics calculated from the hydro-ecoregions subsets of reference and impaired sites, we selected metrics exhibiting the best trade-off between high discrimination efficiency, low specificity, low redundancy and high stability under reference conditions. The IBMG is composed of two taxonomic richness-based metrics, two abundance-based metrics, one trait-related metric and a diversity index. Results on Ephemeroptera communities put in light the important role of this order for the bio-evaluation of small streams submitted to gold-mining. Future fundamental research on the ecology and the taxonomy of this order should thus improve the current bioassessment tool. Finally, this work highlighted the fact that headwater stream small of FG potentially harbor a rich and specific fauna
