Rampant hybridization in an old tropical fern genus (Danaea, Marattiaceae)

open access: yesTAXON, Volume 74, Issue 3, Page 536-552, June 2025.
Abstract The number of hybrids has been reported to be lower in tropical than temperate ferns, but patterns of hybridization are poorly known in the tropics. We examine hybridization in the Neotropical fern genus Danaea (Marattiaceae) using a phylogenomic approach with single or low‐copy nuclear and chloroplast loci and haplotype phasing.

Rapid DNA barcoding‐based fern and lycophyte inventories of protected areas—A pilot study to introduce a simple but effective protocol DNA条形码技术实现保护区生物多样性的快速编目和鉴定——一种不过度依赖分类学家的快速高效的研究手段

open access: yesIntegrative Conservation, Volume 3, Issue 3, Page 196-211, September 2024.
DNA barcoding‐supported inventories of protected areas provide fast assessment with reduced reliance on taxon experts but enhanced effectiveness in recording quality. Feedback loops to taxon experts enable the identification of taxonomic gaps, especially the identification of species not known to science yet.

IV. On the embryology of Angiopteris evecta , hofm [PDF]

open access: yesProceedings of the Royal Society of London, 1892
Abstract During a recent visit to Ceylon I took the opportunity of collecting young plants and prothallia of Angiopteris evecta, with the view of working out the embryology of this type of the eusporangiate Filicineæ, since the development of the embryo is not as yet known in any member of this group.

Evolution of the rpoB-psbZ region in fern plastid genomes: notable structural rearrangements and highly variable intergenic spacers

open access: yesBMC Plant Biology, 2011
Background The rpoB-psbZ (BZ) region of some fern plastid genomes (plastomes) has been noted to go through considerable genomic changes. Unraveling its evolutionary dynamics across all fern lineages will lead to clarify the fundamental process shaping ...
