Signification écologique de la tolérance acquise des communautés microbiennes des biofilms de rivières à une contamination d'origine anthropiques

Author(s) : Tlili, A.
Description : Changes in structure and diversity of biological communities within ecosystems subjected to disturbances, are generally synonymous of the scarcity, loss and/or the emergence of new tolerant species or by the proliferation of other species already present but at low density. This leads to a decrease ...

Les biofilms aquatiques : dans quelle mesure permettent-ils de comprendre l'effet des pesticides sur le fonctionnement des cours d'eau ? Exemple en zone de vignoble

Description : Biofilms are attached microbial assemblages on immersed substrates and play a major ecological role in stream ecosystems. Biofilms interact with dissolved substances and contaminants (such as pesticides), which can directly or indirectly affect their structure and functions. A variety of taxonomic a...

Les biofilms aquatiques : dans quelle mesure permettent-ils de comprendre l'effet des pesticides sur le fonctionnement des cours d'eau ? Exemple en zone de vignoble

Description : Fixés sur des substrats immergés, les biofilms microbiens assurent un rôle écologique majeur dans les petits cours d'eau. Ils interagissent avec les substances dissoutes et les contaminants (et notamment avec les pesticides) qui peuvent modifier leur structure et leur fonctionnement par des effets d...

Recovery potential of periphytic communities in a river impacted by a vineyard watershed

Description : Vineyard areas are important causes of water contamination, especially by pesticides and residues. These compounds can markedly disturb aquatic communities particularly photosynthetic organisms that are targeted by herbicides. Biofilms and diatoms were used as bioindicators for quality assessment in...

Enhanced co-tolerance and co-sensitivity from long-term metal exposures of heterotrophic and autotrophic components of fluvial biofilms

Description : Understanding the interactive effects of multiple stressors on ecosystems has started to become a major concern. The aim of our study was therefore to evaluate the consequences of a long-term exposure to environmental concentrations of Cu, Zn and As on the pollution induced community tolerance (PICT...
