New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: European Journal of Taxonomy, 2021, vol. 753, p. 1-80

Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been...

New data on early Oligocene dormice (Rodentia, Gliridae) from southern Europe : Phylogeny and diversification of the family

Lu, Xiaoyu ; Costeur, Loïc ; Hugueney, Marguerite ; Maridet, Olivier

In: Journal of Systematic Palaeontology, 2021, p. 1-21

Rodents of the extant family Gliridae, commonly called dormice, are common in European faunas since the early Eocene. Here we study for the first time specimens from St-Martin-de-Castillon C (France, early Oligocene) previously reported as Gliravus aff. majori and Pseudodryomys aff. fugax. We now refer them to Butseloglis tenuis and Microdyromys misonnei. Besides the French material, new...

Comment réduire l’impact environnemental du secteur de la construction grâce aux outils de l’économie circulaire ?

Nyffenegger, Vincent Joseph ; Dunand, Christophe-Alexandre (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDEE 435.

Dans un monde où les problèmes environnementaux s’accumulent, de nouveaux modèles économiques ont vu le jour et, c’est ainsi qu’est née l’économie circulaire. Cependant, ces modèles peinent encore à être appliqués dans les domaines d’activités ayant un fort impact environnemental pour diverses raisons alors que l’urgence d’une transition écologique ne fait...

A multi-platform package for the analysis of intra- and interspecific trait evolution

Gaboriau, Théo ; Mendes, Fábio K. ; Joly, Simon ; Silvestro, Daniele ; Salamin, Nicolas

In: Methods in Ecology and Evolution, 2020, p. -

Evolutionary forces affect the distribution of phenotypes both within and among species. Yet, at the macro‐evolutionary scale, the evolution of intraspecific variance is rarely considered. Here, we present an r and a BEAST 2 implementation that extends the JIVE (Joint inter‐ and Intraspecific Variance Evolution) model aimed at the analysis of continuous trait evolution at both inter‐...
