“…Because the abundance of alkanes decreased with leaf age in the fern Polybotrya cervina (Voglgruber, 2011) and fatty acids in cuticular waxes decreased by 80% in angiosperm leaves (Yang & Ohlrogge, 2009), these substances might inhibit epiphyll colonization on younger leaves. Unfortunately, Cerón‐Carpio et al (2019) did not investigate the wax composition of senescent leaves of our fern species to prove chemical alterations of the leaf cuticles. Yet, Danaea nodosa contained these substances such as cinnamomic acid in its cuticle but was still a superhost for foliicolous lichens.…”

Questions Leaf traits play an important role in the epiphyll colonization of leaves. Although ferns are common in forest understories, they have been widely ignored as possible host plants. We asked: How does epiphyll colonization (cover, richness, and composition) differ among fern species depending on their leaf longevity and surface wettability? Location Tropical Biological Station of “Los Tuxtlas”, Veracruz (Mexico). Methods Epiphyll cover was monitored on leaves of six individuals per species after 2, 5, 12, 16.5, and 26 months. Leaf longevity was calculated from leaf turnover rates over 24 months. Leaf wettability was determined through the contact angle technique. Results All studied fern species had hydrophilic leaf surfaces. Fern species with shorter leaf longevity (14.4–17.8 months) were colonized faster by epiphylls than species with longer leaf life spans (33.9–38.8 months). The area of the oldest leaves was covered to 1.2%–26.1% by foliicolous lichens and to 0.3%–2.2% by green algae. Foliicolous lichens were more species‐rich on Danaea nodosa (27 spp.) than on the other fern species (1–9 lichen spp.). Foliose liverworts thrived on the only riparian fern (3.57%). Only 0.04%–1.1% of the area of plastic substrates was colonized by epiphylls. Conclusions The hydrophilic leaf surfaces of ferns facilitated the colonization of epiphylls, especially of foliicolous lichens. The speed of epiphyll colonization was faster in ferns with shorter leaf longevity but increased in all species with leaf age. However, the relatively low epiphyll cover on fern leaves and artificial substrates in our study might be related to unfavorable microclimatic parameters.

“…Phenolic acids, flavonoids, steroids, and their derivatives are commonly reported from ferns of different families (Bohm & Tryon 1967, Cao et al 2017, Cerón-Carpio et al 2019, Cui et al 1993, Ueno et al 1963. Phytoecdysteroids are also reported from various species of ferns (Cao et al 2017, Dinan 2001, Hu et al 2014.…”

Background: Traditional use of pteridophytes as food and medicine is a common practice around the world. Many ethnic communities hold vast knowledge about the uses of pteridophytes and the documentation of such knowledge and biodiversity of edible and medicinal pteridophytes is important for health care, food security and conservation. Although being one of the biodiversity rich countries, the detailed use of edible and medicinal pteridophytes from Nepal is not well documented and they are one of the underutilized plant resources having vast potential. Thus, the aim of this review is to compile the knowledge about the use of edible and medicinal pteridophytes in Nepal.Methods: Relevant information on traditional uses as medicinal and edible species were collected form published literatures such as research articles on ethnobotanical surveys, books, book chapters and conference proceedings.Results: The literature survey revealed that a total of 26 species of pteridophytes were used as food and 43 species were used as traditional medicines. Among 55 useful species, 14 species were used as both food and traditional medicine. Diplazium esculentum, Diplazium maximum, Dryopteris cochleata and Ophioglossum reticulatum were common edible species and Aleuritopteris albomarginata, Equisetum ramosissimum, Nephrolepis cordifolia and Tectaria coadunata were common medicinal pteridophytes. Most of species are growing in natural habitat and the potential utilization species were sold in the market which has also supported livelihood. Some of these pteridophytes were also used in preparation of ethnic foods such as fermented foods and pickles. Conclusion:Findings from the study suggested that only a few common species of pteridophytes are used as food and traditional medicines Nepal. The knowledge about the traditional uses of pteridophytes and their biodiversity is also affected by socioeconomic changes in communities, lack of sharing of traditional knowledge through generations, improper collection practices and climate change. Very few pteridophytes from Nepal have been studied in detail for their phytoconstituents and biological activities and safety. Future research activities should focus on providing scientific evidence for traditional uses as well as development of proper conservation, cultivation, and product formulation methods in a sustainable manner.

“…The decrease in ABA concentration causes the onset of the anteridiogen sensitive period. The ferns also contain various amounts of fatty acids and alkanes, pigments, carbohydrates, amino-acids, proteins and lipids, with lower concentrations of aldehydes, esters, ketones, and primary alcohols, resulting in a very complex and species-specific composition [ 63 , 64 ].…”

The area of phytosynthesized nanomaterials is rapidly developing, with numerous studies being published yearly. The use of plant extracts is an alternative method to reduce the toxic potential of the nanomaterials and the interest in obtaining phytosynthesized nanoparticles is usually directed towards accessible and common plant species, ferns not being explored to their real potential in this field. The developed nanoparticles could benefit from their superior antimicrobial and antioxidant properties (compared with the nanoparticles obtained by other routes), thus proposing an important alternative against health care-associated and drug-resistant infections, as well as in other types of applications. The present review aims to summarize the explored application of ferns in nanotechnology and related areas, as well as the current bottlenecks and future perspectives, as emerging from the literature data.
