Caractéristiques hydro-géomorphologiques des microhabitats d’Unio crassus (Ardenne, Belgique) ; Hydro-geomorphological characteristics of Unio crassus microhabitats (Ardenne, Belgium)

peer reviewed ; Populations of Unio crassus (Bivalvia: Unionidae) are sharply declining in Europe. To reverse this trend, many conservation actions are being implemented. However, the effectiveness of these actions depends on our knowledge of the ecology of the species. This study focuses on the hydromorphological preferences of U. crassus in a river in south-eastern Belgium (the Sûre River). Depth and flow velocities were mapped at 3 study sites. These data were then cross-referenced with the spatial distribution of individuals at these sites in order to relate the use and availability of mic... Mehr ...
