Isolated Projects

On retrouve dans ce programme des projets développés rapidement sur des thématiques limitées.

Leiocola is a small liverwort genus with a circumboreal distribution and around 8 species known for Europe, 1 in North America, and 4 species in Asia. The circumscription of the genus Leiocolea (Marchantiophyta), its systematic placement (Lophoziaceae versus Jungermanniaceae) and its phylogenetic affinities are all somewhat controversial. Recent molecular studies have revealed that Leiocolea is a good taxon and it was to be placed in a newly ressurected family, the Mesoptychiaceae. The other genera placed in the Mesoptychiaceae (Hattoriella - 2-4 sp., Liochlaena - 3-4 sp. And Mesoptychia - 1sp.) are all small and warrent further taxonomic investigation. This research project consists of a systematic revision of the genus Leiocolea and it putative allies within the Mesoptychiaceae so as to better understand the circumscriptions and systamatic affinities of the genera and to provide a platform for molecular phylogenetic analyses of the Mesoptychiacea and its phylogenetic placement within the Jungermannidiae.
