Frontiers in Plant Science, 2013 Ferns are some of the oldest vascular plants in existence and they are the second most diverse lineage of tracheophytes next to angiosperms. Recent efforts to understand fern success have fo-cused on the physiological capacity and stress tolerance of ...

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants
American Journal of Botany, Volume 113, Issue 4, April 2026.Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Phylogenetic analyses place the Australian monotypic Revwattsia in Dryopteris (Dryopteridaceae)
PhytoKeys, 2012 Revwattsia fragilis (Watts) D.L. Jones (Dryopteridaceae), originally described as a Polystichum Roth by the pioneer Australian botanist Reverend W.W. Watts in 1914, is a rare epiphytic fern endemic to northeastern Queensland, Australia. Known from only a

Ecology and Evolution, Volume 16, Issue 4, April 2026.We investigate the stratification of five clades of Lepidoptera: Erebidae‐Arctiinae, Geometridae, Hedylidae, Saturniidae, and Sphingidae in a tropical rain forest of the Chocó region in NW Ecuador. Average species richness was higher in the understory, median sample sizes were similar between strata and we found more species in regenerating forests ...

Cyanogenesis prospection in galled and non-galled tissues of Microgramma squamulosa (Polypodiaceae)
Lilloa, 2020 Cyanogenic glycosides are defense substances that can produce hydrocyanic acid when they undergo hydrolysis as a result of herbivory, a process called cyanogenesis.

Significance of gametophyte form in tropical, epiphytic ferns
, 2018 Fern gametophytes are variable in growth form and longevity. Most are short-lived and cordate in outline. Others are long-lived, ribbon-like or filamentous, and clone-forming, and some produce gametophytic gemmae. Literature, field, and laboratory studies reveal that persistent, clone-forming gametophytes are typical of rainforest epiphytes.

Diversity and host preferences of ferns and lycopods epiphytes on palm trees
Biodiversitas Journal of Biological Diversity, 2019 Abstract. Praptosuwiryo TN, Sumanto, Cahyaningsih. 2019. Diversity and host preferences of ferns and lycopods epiphytes on palm trees. Biodiversitas 20: 3731-3740. Epiphytic ferns contribute importantly to the global biodiversity of tropical rain forests. However, our knowledge of the ecology of epiphytic ferns is phenomenally still limited.
