A 4000-species dataset provides new insight into the evolution of ferns.
A community‐derived classification for extant lycophytes and ferns
TLDR
A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.
A revised family-level classification for eupolypod II ferns (Polypodiidae: Polypodiales)
We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life
Morphological innovation, ecological opportunity, and the radiation of a major vascular epiphyte lineage
TLDR
It is found that diversification rates in the Polypodiaceae are positively correlated with changes in elevation, and Repeated successful exploration of novel habitat types, rather than morphological innovation, appears to be the primary driver of diversification in this group.
Stasis and convergence characterize morphological evolution in eupolypod II ferns.
TLDR
This study provides some of the first hypotheses of character evolution at the family level and above in light of recent phylogenetic results, and promotes further study in an area that remains open for original observation.
Eurasian origin, boreotropical migration and transoceanic dispersal in the pantropical fern genus Diplazium (Athyriaceae)
TLDR
The current tropical amphi-Pacific disjunctions in subgenus Diplazium can be better explained by the disruption of boreotropical belt, however, long-distance dispersal between Eurasia and tropical America cannot be ruled out.
Silica bodies and their systematic implications in Pteridaceae (Pteridophyta)
TLDR
It is demonstrated that the distribution of epidermal silica bodies is homoplastic within Pteridaceae, but that they act as a potential synapomorphies for several different groups within the family.
Phylogeny and historical biogeography of the lastreopsid ferns (Dryopteridaceae).
TLDR
Diversification among the main clades of the lastreopsid ferns was influenced by climatic and geological changes in the southern hemisphere, and taxonomic recognition of Parapolystichum is warranted to preserve the monophyly of Lastreopsis.
Global phylogeny and biogeography of grammitid ferns (Polypodiaceae).
Systematics of Grammitid Ferns (Polypodiaceae): Using Morphology and Plastid Sequence Data to Resolve the Circumscriptions of Melpomene and the Polyphyletic Genera Lellingeria and Terpsichore
TLDR
This work focuses on resolving the circumscriptions of some large Neotropical genera by focusing on a clade, identified in previous analyses, that includes the monophyletic genus Melpomene, plus portions of two polyphyletic genera, Lellingeria and Terpsichore.
