Due to their ubiquitous occurrence and taxonomic diversity, diatoms have become widely used for monitoring the environmental conditions in freshwater. Metal contaminations affect water quality and may lead to shifts in diatom community structure as well as individuals' morphology. In the present study the characteristics of periphytic biofilms were analysed in situ (Riou-Mort watershed, South West France), and under experimental conditions. The metals (cadmium and zinc) caused a replacement of sensitive diatom species (Cyclotella meneghiniana, Navicula gregaria, Navicula veneta) by more tolerant ones (Eolimna minima especially), but also induced a reduction in size of some individuals, and / or an apparition of valve abnormailites. Not only...
