A classification for extant ferns
A revised classification for extant ferns is presented, with emphasis on ordinal and familial ranks, and a synopsis of included genera is provided, reflecting recently published phylogenetic hypotheses based on both morphological and molecular data.
Ferns diversified in the shadow of angiosperms
It is shown that polypod ferns (> 80% of living fern species) diversified in the Cretaceous, after angiosperms, suggesting perhaps an ecological opportunistic response to the diversification of angios perms, as angiosPerms came to dominate terrestrial ecosystems.
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences.
The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
The scope of the analysis provides unprecedented insight into overall fern relationships, not only delivering additional support for the deepest leptosporangiate divergences, but also uncovering the composition of more recently emerging clades and their relationships to one another.
Evidence for a Cenozoic radiation of ferns in an angiosperm-dominated canopy
New insight is provided into leptosporangiate diversification and the evolution of epiphytism by integrating a 400-taxon molecular dataset with an expanded set of fossil age constraints and finds evidence for a burst of fern diversification in the Cenozoic.
A community‐derived classification for extant lycophytes and ferns
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
The Utility of Nuclear gapCp in Resolving Polyploid Fern Origins
New primer sequences for the amplification of a portion of the nuclear gapCp gene (encoding a glyceraldehyde-3-phosphate dehydrogenase) are presented and it is demonstrated that these primers are nearly universal for this clade of ferns.
Plastid atpA data provide improved support for deep relationships among ferns
The atpA dataset had more variable characters and resulted in a more robustly supported phylogeny than any of the other single gene datasets examined, suggesting that at pA will be exceptionally useful in more extensive studies of fern phylogeny and perhaps also in studies of other plant lineages.
