A molecular phylogeny of scaly tree ferns (Cyatheaceae)

open access: yesAmerican Journal of Botany, 2007
Tree ferns recently were identified as the closest sister group to the hyperdiverse clade of ferns, the polypods. Although most of the 600 species of tree ferns are arborescent, the group encompasses a wide range of morphological variability, from diminutive members to the giant scaly tree ferns, Cyatheaceae.

Environmental factors affect population structure of tree ferns in the Brazilian subtropical Atlantic Forest [PDF]

open access: yesActa Botânica Brasílica, 2020
Tree ferns are important elements of tropical forests, mainly because they are common and provide microhabitats for epiphytic plants. Due to their ecological importance, the aim of this study was to evaluate population structure, distribution, and ...

What makes a good phorophyte? Predicting occupancy, species richness and abundance of vascular epiphytes in a lowland seasonal tropical forest

open access: yesFrontiers in Forests and Global Change, 2022
Epiphytes typically exhibit clustered distribution patterns, but predicting the spatial variation of their distribution at fine scales has long been a challenge. Taking advantage of a canopy crane giving access to 1.1 ha of lowland seasonal rainforest in

How early ferns became trees [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2001
A new anatomically preserved fern, discovered from the basalmost Carboniferous of Australia, shows a unique combination of very primitive anatomical characters (solid centrarch cauline protostele) with the elaboration of an original model of the arborescent habit.
