Distribution models and environmental changes : Application to echinoid faunas in the Southern Ocean and ecoregionalization
2018
Current environmental changes, which impact marine environments, cover major scientific and societal issues, especially as these environmental changes are expected to accelerate along the 21st century. Understanding and forecasting the response of marine biodiversity to these changes is a pregnant scientific issue. Biogeographic and macroecological approaches provide a scientific framework for that purpose. They allow describing and understanding species distribution patterns at large spatial scale as well as estimating their potential shift with regards to environmental change. This is particularly true in the Southern Ocean, where the effects of climate change are already occurring and wh…
The impact of urban contamination on antibioresistance in microbial communities from periphyton and sediments
2020
International audience; Since the early 20's antibiotics have been massively produced and consumed for the benefit of bothhuman and animal health. Nevertheless, antibiotics have also reached the aquatic environmentthrough diffuse sources (e.g. veterinary treatment, contaminated manure application...) and throughwastewater. Consequently, antibiotics concentrations between the ng/L and μg/L range are regularlydetected in surface water and those molecules have also been found in sediments and aquatic biota.The ubiquitous presence of antibiotics exerts a selective pressure on microbial communities leading tothe acquisition and dissemination of antibioresistance in the environment. While both an…

Synchronous Early Holocene glacier behavior in the European Alps – Evidences from a new cosmogenic 10Be chronology of Argentière glacier (Mont-Blanc …
2018
Reconstruction of past glacier fluctuations is an important step towards the comprehension of glacier responseto past and future climate changes. Moraine deposits and roches moutonnées represent univocal geomorphicmarkers of advanced glacier extensions, and their dating using in situ-produced cosmogenic nuclides is a valuableapproach for better constraining past glacier behavior.To better understand the past glacier fluctuations in the European Alps, this study focuses on the Argentièreglacier, located on the north-western flank of the Mont-Blanc massif (MBM) in the Western Alps, and hostingsome of the largest European glaciers. Here, gemorphological analysis and new 10Be exposure ages obta…
