Free-living amoebae in sediments from the Lascaux Cave in France

2013

The Lascaux Cave in France is an old karstic channel where the running waters are collected in a pool and pumped to the exterior. It is well-known that water bodies in the vicinity of humans are suspected to be reservoirs of amoebae and associated bacteria. In fact, the free-living amoebae Acanthamoeba astronyxis, Acanthamoeba castellanii, Acanthamoeba sp. and Hartmannella vermiformis were identified in the sediments of the cave using phylogenetic analyses and morphological traits. Lascaux Cave sediments and rock walls are wet due to a relative humidity near saturation and water condensation, and this environment and the presence of abundant bacterial communities constitute an ideal habitat…

Programme-cadre FENOIR (Figurations de l’environnement nocturne des territoires réunionnais). Rapport d’étape pour le Parc national de La Réunion

2022

Soumise à une importante poussée démographique, l’île de La Réunion a vu sa population urbaine fortement augmenter – passant de 44 % de la population totale en 1975 à 95 % en 2015. Directement corrélée aux formes et dynamiques spatiales de l’urbanisation, l’empreinte lumineuse sur l’île a connu une mutation radicale ces dernières années : son emprise et sa pression ont considérablement augmenté sur l’ensemble du territoire, depuis la côte jusqu’à l’intérieur même du Parc national de La Réunion qui recouvre plus de 76 % du territoire insulaire (42 % pour la zone cœur). Acteur incontournable des enjeux environnementaux sur l’île, le Parc national a mené très tôt des actions autour des effets …

Indoor floors from Gien (8th-10th c. AD). Buildings materials, use of space and formation processes

2017

International audience; The refurbishing of the National museum of hunting at Gien (France) offers the opportunity to uncover the early castral occupation (8th-10th c. AD). High status habitats have been explored by archaeological and geoarchaeological methods, including micromorphology. The very well preservation of indoor floors allows to get data on building materials and the use of space, such as domestic housing, craft working and cereal processing.

The starry sky, a territorial commons?

2021

International audience; Flagstaff, Arizona, United States, April 15, 1958: the city council adopts the ordinance n°440 which aims at “preventing a rapid deterioration of the visibility of the starry sky”. This regulation results from the mobilization of the Lowell Observatory astronomers against certain public lighting devices. Through this political act, the elected officials place their city at the epicenter of an emergent international movement: the ‘Dark-sky movement’. The first replica of this movement is felt in 1972 in Tucson, Arizona. From a discomfort perceived by astronomers from the Lowell and Kitt Peak observatories, the idea of ‘light pollution’ emerges and begins to spread thr…

Le "mille-feuille" des labellisations d'aires protégées en France : entre indigestion locale, complémentarité régionale et cohérence nationale

2022

National audience; Le leitmotiv du mille-feuille des aires protégées à la française est bien connu mais peu documenté. 20 types de labellisation peuvent être déployés à l’échelle métropolitaine, entrainant des superpositions spatiales non négligeables. Labelliser une aire protégée dans un territoire, c’est une cascade de processus qui s’inscrit dans l’histoire du droit de l’environnement. Cet écheveau complexe à la fois temporel, spatial et politique permet d’expliquer « l’indigestion » locale de la part des parties-prenantes, la complémentarité régionale qui actionne différents leviers règlementaires, administratifs et financiers et la cohérence nationale et internationale. Mais la labelli…

Au sein du CNRS, un Observatoire de l’environnement nocturne pour accompagner la territorialisation de la lutte contre la pollution lumineuse

2022

National audience; Jusqu’à présent, les politiques de préservation de l’environnement nocturne peinent à saisir l’ensemble des effets négatifs de la lumière artificielle nocturne (ALAN). La question de la qualité de l’environnement nocturne n’est ainsi que partiellement traitée. D’une part, les enjeux liés à l’efficience énergétique des systèmes techniques d’éclairage et à la qualité du ciel étoilé occultent quasi systématiquement les enjeux écologiques et sanitaires de la préservation de l’obscurité. D’autre part, un fossé considérable persiste entre des solutions de mitigation technique à l’échelle locale et la mise en œuvre, à des échelles plus larges, de zonages construits par et pour d…
