Cephalopod prey of light-mantled sooty albatross Phoebetria palpebrata, resource partitioning amongst Kerguelen albatros...
The cephalopod diet of the light-mantled sooty albatross Phoebetria palpebrata was determined for the first time at the subantarctic Kerguelen Islands by sorting ∼7000 accumulated beaks from 66 regurgitated boluses. Twenty-two taxa were identified, including four dominant squid species that are all endemic to the Southern Ocean: Galiteuthis glacial...
Calibrating ecological indicator values and niche width for a Mediterranean flora
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 ...
Fingerprinting and source apportionment of dioxin contamination of soils and chicken eggs in Southeast and Central Vietn...
Published in Environmental science and pollution research international
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 : des adaptations spécifiques, une écologie sous contrainte, un intérêt en bioindication
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...
Food webs speak of human impact: Using stable isotope-based tools to measure ecological consequences of environmental ch...
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...
Partage d'expériences d'EDF sur la mise en oeuvre de la directive cadre européenne sur l'eau
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...
Metals in Calluna vulgaris, Empetrum nigrum, Festuca vivipara and Thymus praecox ssp. arcticus in the geothermal areas o...
Published in Environmental science and pollution research international
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...
The effects of inflow of agricultural biogas digestate on bivalves' behavior.
Published in Environmental science and pollution research international
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,...
Significant impact of seasonality, verticality and biofilm on element accumulation of aquatic macrophytes.
Published in Environmental pollution (Barking, Essex : 1987)
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...
