Based on the examination of extensive herbarium material and considering the existing literature, we recognize seven species in Europe outside Russia. These are T. palustris, T. integrifolia with subsp. integrifolia, subsp. aurantiaca, subsp. capitata, subsp. maritima, subsp. serpen­tini and subsp. “tundricola”, T. balbisiana, T. crispa, T. helenitis, T. longifolia and T. papposa. Phylogenetic analysis of ITS and ETS sequences showed that these species fall into three lineages. These are: (1) T. palustris, clearly related to Arctic species of the genus; (2) T. integrifolia; and (3) the remaining species. Molecular dating of the T. integrifolia lineage resulted in a crown group age of 1.76 (0.85 – 2.87) million years. Possible reasons for taxonomic difficulties in the genus in Europe outside Russia may include its young phylogenetic age and extensive migration and genetic admixture in the Quaternary. The decline of the genus in Europe outside Russia is documented and discussed. We consider it possible that its decline is related to rising global temperatures.

Range and niche expansion through multiple interspecific hybridization: a genotyping by sequencing analysis of Cherleria (Caryophyllaceae) / ABIGAIL J. MOORE A.J. / 2021    

in 21 - 2021 - 21-BMC Ecology and Evolution-2021 (Bulletin de BMC Ecology and Evolution) Titre : Range and niche expansion through multiple interspecific hybridization: a genotyping by sequencing analysis of Cherleria (Caryophyllaceae) Type de document : texte imprimé Auteurs : ABIGAIL J. MOORE A.J., Auteur ; Jessica A. MESSICK J. A., Auteur ; KADEREIT J.W., Auteur Année de publication : 2021 Importance : 40-62 Langues : Français (fre) Résumé : Cherleria (Caryophyllaceae) is a circumboreal genus that also occurs in the high mountains of the northern hemisphere. In this study, we focus on a clade that diversified in the European High Mountains, which was identified using nuclear ribosomal (nrDNA) sequence data in a previous study. With the nrDNA data, all but one spe-cies was monophyletic, with little sequence variation within most species. Here, we use genotyping by sequencing (GBS) data to determine whether the nrDNA data showed the full picture of the evolution in the genomes of these species. Results: The overall relationships found with the GBS data were congruent with those from the nrDNA study. Most of the species were still monophyletic and many of the same subclades were recovered, including a clade of three nar-row endemic species from Greece and a clade of largely calcifuge species. The GBS data provided additional resolu-tion within the two species with the best sampling, C. langii and C. laricifolia, with structure that was congruent with geography. In addition, the GBS data showed significant hybridization between several species, including species whose ranges did not currently overlap. Conclusions: The hybridization led us to hypothesize that lineages came in contact on the Balkan Peninsula after they diverged, even when those lineages are no longer present on the Balkan Peninsula. Hybridization may also have helped lineages expand their niches to colonize new substrates and different areas. Not only do genome-wide data provide increased phylogenetic resolution of difficult nodes, they also give evidence for a more complex evolutionary history than what can be depicted by a simple, branching phylogeny.
