The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Chemistry – A European Journal, EarlyView.An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

Journal of Quaternary Science, EarlyView.ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Limnological characteristics of 25 lakes of the French Massif Central [PDF]
Annales de Limnologie - International Journal of Limnology, 2002 Les concentrations en elements majeurs des eaux de 25 lacs naturels du Massif Central ont ete determinees a partir de l'analyse chimique de 206 echantillons preleves entre mai 1996 et mai 1998. Pour chaque lac, 6 a 9 echantillons ont ete analyses. Les valeurs moyennes et les ecart-types sont calcules pour les variables chimiques telles que l'alcalinite

Journal of Quaternary Science, EarlyView.ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Journal of Raman Spectroscopy, EarlyView.Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman
