Global diversification of the common moonwort ferns (Botrychium lunaria group, Ophioglossaceae) was mainly driven by Pleistocene climatic shifts.

ABSTRACT:

Background and aims

The cosmopolitan Botrychium lunaria group belongs to the most species-rich genus of the family Ophioglossaceae and was considered to consist of two species until molecular studies in North America and northern Europe led to the recognition of multiple new taxa. Recently, additional genetic lineages were found scattered in Europe, emphasizing our poor understanding of the global diversity of the B. lunaria group, although the processes involved in the diversification of the group remain unexplored.

Methods

We conducted the first global phylogenetic study of the group, including 533 ingroup accessions sequenced for four plastid loci. We compared results of Bayesian and maximum likelihood-based methods. We used the phylogenetic relationship we recovered to e
