Microdiversity characterizes prevalent phylogenetic clades in the glacier-fed stream microbiome

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Massimo Bourquin, Tyler Joe Kohler, Jade Brandani, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas

Glacier-fed streams (GFSs) are extreme and rapidly vanishing ecosystems, and yet they harbor diverse microbial communities. Although our understanding of the GFS microbiome has recently increased, we do not know which microbial clades are ecologically succ ...

Role of photosymbiosis in the Late Triassic expansion of shallow-water Scleractinia

Anders Meibom

Since their appearance in the Anisian (ca. 240 Ma) scleractinian corals rapidly diversified and expandedacross shallow marine environments, becoming the main builders of reefs. This ecological success coralsowe to their symbiotic relationship with photosyn ...

Photosymbiosis and the expansion of shallow-water corals

Anders Meibom, Jaroslaw Hubert Stolarski

Roughly 240 million years ago (Ma), scleractinian corals rapidly expanded and diversified across shallow marine environments. The main driver behind this evolution is uncertain, but the ecological success of modern reefbuilding corals is attributed to thei ...

The ancient evolutionary origins of Scleractinia revealed by azooxanthellate corals

Anders Meibom, Jaroslaw Hubert Stolarski

Background: Scleractinian corals are currently a focus of major interest because of their ecological importance and the uncertain fate of coral reefs in the face of increasing anthropogenic pressure. Despite this, remarkably little is known about the evolu ...

Fiber optic distributed temperature sensing for the determination of the nocturnal atmospheric boundary layer height

Wolf Hendrik Huwald, Marc Parlange

A new method for measuring air temperature profiles in the atmospheric boundary layer at high spatial and temporal resolution is presented. The measurements are based on Raman scattering distributed temperature sensing (DTS) with a fiber optic cable attach ...

Atmospheric nitrous oxide during the last 140,000years

Jérôme Chappellaz

Typical rapid climate events punctuating the last glacial period in Greenland, Europe and Antarctica are compared to two rapid events occurring under warmer conditions: (i) Dansgaard-Oeschger event 25, the first abrupt warming occurring during last glacial ...

Using geotypes for landslide hazard assessment and mapping: a coupled field and GIS-based method

Aurèle Parriaux, Séverine Bilgot

Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduces in 1997 a method to realize landslide hazard maps. It is routinely u ...

Typology of recent groundwaters from different aquifer environments based on geogenic tracer elements

A key problem in environmental science and in engineering geology is the often incomplete understanding of the origin of dissolved components in groundwater. The dissolved contents of trace elements in groundwater are of special importance for groundwater ...

A natural shock-induced dense polymorph of rutile with alpha-PbO2 structure in the suevite from the Ries crater in Germany

Philippe Gillet

A dense post-rutile titanium dioxide (TiO2) phase was discovered in shocked garnet gneisses from the Ries crater by reflected-light microscopy, laser rnicroRaman spectroscopy and micro-beam X-ray diffraction. The Raman spectrum consists of nine bands at wa ...

Typologie des aquifères évaporitiques du trias dans le bassin lémanique du Rhône (Alpes occidentales )

The typology of evaporitic aquifers is part of the AQUITYP research project, whose principal aim is the hydrogeological characterization of different aquifer types between the Jura and the Swiss Alps. This study has been directed by the Geology laboratory ...
