Dans un contexte de dégradation généralisée des écosystèmes d’eau douce et d’érosion de la biodiversité, une surveillance accrue de l’état écologique de ces milieux est indispensable. L'évaluation de l’état écologique des eaux douces est généralement réalisée par le biais d’inventaires des communautés biologiques qui y résident, indicatrices de la ...

In this research, diatoms as the first step and fishes as the last step of the food chain were compared as toxic metal accumulation bioindicator in an A-class wetland in Turkey. Bioaccumulations of potentially toxic elements (PTEs) were determined in liver, gill and muscle tissues of two commercially consumed fish species Carassius gibelio and Cypr...
Bioindication of ecological variables such as humidity, temperature or pH by ecological indicatorvalues of plants is a powerful tool for research in plant ecology, e.g. to detect early vegetationchanges. Here, we provide a data set of ecological indicator values including niche width for anentire regional flora. We used an extensive data-base with ...

Free-range chicken eggs and topsoil samples from private households in Southeast and South Central Coast of Vietnam were investigated to identify potential PCDD/F sources using Positive Matrix Factorization (PMF) approach. The PMF-extracted egg congener patterns were transformed to soil patterns using bioaccumulation factors and then compared to ex...
Les plantes aquatiques constituent un groupe végétal fonctionnel particulier, caractérisé non pas par une filiation taxinomique, mais par leur inféodation à un habitat étroitement lié à la présence d'eau. Relativement peu connue des botanistes comme du public, cette flore a été peu étudiée pour différentes raisons. L'accès à ces formations végétale...
Linking their major biotic and abiotic components, food webs form the core of ecosystems, many of which are today exposed to multiple human impacts acting at several spatial and temporal scales. A food web perspective allows for a quantification of environmental change effects on both the structure of biological diversity and the functioning of eco...
En tant qu’usager et gestionnaire d’eaux de surface, EDF contribue pleinement à l’atteinte du bon état écologique défini par la directive cadre européenne sur l’eau. La direction « Recherche et Développement » d’EDF (EDF R&D) s’est donc mobilisée pour fournir une expertise sur les bioindicateurs retenus, notamment pour les poissons. L’objectif étai...

This investigation was conducted to identify the content of metals in Calluna vulgaris (family Ericaceae), Empetrum nigrum (family Ericaceae), Festuca vivipara (family Poaceae) and Thymus praecox subsp. arcticus (family Lamiaceae), as well as in the soils where they were growing in eight geothermal heathlands in Iceland. Investigation into the vege...

This study focused on the reaction of bivalve molluscs to biogas digestate, which is a waste product of an increasingly developing biogas production in rural areas worldwide. The effects of biogas digestate on aquatic organisms are not fully known, and neither this substance nor any types of manure were tested in the monitoring based on valvometry,...

Submersed macrophytes accumulate large amounts of macro- and trace elements from the environment and, therefore, are frequently used as indicators of water pollution and tools to remove pollutants from contaminated waters. This study provides evidences that the quantity of macro- and trace elements accumulated in the macrophyte Ceratophyllum demers...
