| The coastline has many activities related to water quality such as bathing activities. Coastal catchments are known to be source of microbial input to the marine environment, their flows and runoff bringing important quantities of sediment, bacteria and other particles. Thus, a network of monitoring and modeling may be necessary to prevent economic losses such as a closure of beaches due to contamination. Hence, within the framework of project GIRAC, a modeling of river and E. coli flow in the Sainte-Anne catchment was developed. To implement the model AVSWAT on the catchment, a data collection (stream gauging, E. coli analyses) and work on GIS was necessary. The aim of this study is the hydrological and microbiological characterization of the catchment.... |

| We sampled 0-group sole juveniles (N = 174) in September and October 2003 in 9 major nurseries located along the French Atlantic coast (English Channel and Bay of Biscay). 0-group sole were infected with 3 genera of digenean metacercariae, Timoniella spp. (Acanthostomidae), Prosorhynchus crucibulum and Prosorhynchus sp. A (Bucephalidae), Podocotyle sp. (Opecoelidae), and an unidentified species of Digenea. Parasite infection levels in the English Channel nurseries were lower, and the community composition was different from Bay of Biscay nurseries. We hypothesize that the difference between geographic areas was due to differences in first intermediate host communities and, to a lesser extent, because of lower temperatures in the English Channel compared to... |

| We determined in this study the habitat preferences of seven native fish species in a regulated river in Southeastern Brazil. We tested the hypothesis that fishes differ in habitat preference and that they use stretches of the river differing in hydraulic characteristics and substrate type. We surveyed fishes in four 1-km long river stretches encompassing different habitat traits, where we also measured water depth, velocity, and substrate type. We investigated preference patterns of four Siluriformes (Loricariichthys castaneus, Hoplosternum littorale, Pimelodus maculatus, and Trachelyopterus striatulus) and three Characiformes (Astyanax aff. bimaculatus, Oligosarcus hepsetus, and Hoplias malabaricus), representing approximately 70% of the total number of... |
