Vie 231 <p>The peristome is considered to be the most complex and conservative morphological structure in the mosses. The arthrodontous peristome is composed of a single, or double, ring of teeth that surrounds the capsule’s opening in the peristomate mosses. Peristome features have long been used for classification at the higher taxonomic ranks and its structural complexity makes it a powerful criterion for unraveling evolutionary events across the mosses. In the monophyletic Dicranidae, a group that contains a third of total moss diversity, the peristome is haplolepidous with a single ring of teeth. In this thesis, the combination of anatomy and morphology allowed for a global comparison of peristomes in and across the Dicranidae. New diagnostic features for peristome pattern identification have been found and the taxonomic importance of the peristome at lower taxonomic ranks has been confirmed in the Dicranidae. </p> Peristome Mosses Bryophyte Taxonomy Evolution Hygroscopic movements Morphology Histology Dewey 580 45 Département des sciences végétales 163 false 1240 Laboratory of Plant Systematics and Biodiversity eb217f7c-2f47-461e-9293-931b6dc1c79d Thesis Public Ruche-Mathilde-Thesis.pdf 36435445 application/pdf CC BY-NC-SA-4.0 Private 2024-07-01 660ec485fffc4861bdf84febfc5912467cbff7a89565499b63c9d43e25b1e021 4d7917d4-a899-428a-99b8-ce8e3d925780 Imprimatur Public IMPRIMATUR.pdf 473108 application/pdf 204d1d977137f77245b7154012def970e7ae74fa1447d4dad67a585f2f749813 openAccess Faculté des sciences / Section de biologie / Département des sciences végétales
