Asplenium bird’s nest ferns in rainforest canopies are climate-contingent refuges for frogs

open access: yesGlobal Ecology and Conservation, 2014
Epiphytes are important for canopy dwelling organisms because they provide a cool and moist microhabitat in the relatively hot and dry canopy. Here we examine whether epiphytic Asplenium ferns act as important habitats for arboreal frogs.

Beta Human Papillomaviruses Seropositivity and the Association With Cutaneous Squamous Cell Carcinoma—A Systematic Review and Meta‐Analysis

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Cutaneous squamous cell carcinoma (cSCC) is one of the most common nonmelanoma skin cancers, with increasing incidence globally. Beta genus human papillomaviruses (β‐HPVs), particularly in immunocompromised individuals, have been implicated in the development of cSCC. However, the strength of association between β‐HPV seropositivity

Genome-wide identification of five fern bHLH families and functional analysis of bHLHs in lignin biosynthesis in Alsophila spinulosa

open access: yesBMC Genomics
Background The basic helix-loop-helix (bHLH) transcription factors are involved in the biosynthesis of various secondary metabolites. However, genome-wide studies on the bHLH gene family in ferns and their role in lignin biosynthesis remain limited.

Target sequence capture of nuclear‐encoded genes for phylogenetic analysis in ferns

open access: yesApplications in Plant Sciences, 2018
Premise of the Study Until recently, most phylogenetic studies of ferns were based on chloroplast genes. Evolutionary inferences based on these data can be incomplete because the characters are from a single linkage group and are uniparentally inherited.
