“…In addition, these conditions greatly affect the distribution of pteridophytes to be higher and wider. Previous studies also reported that tropical rainforests had a very high diversity and abundance of plants, especially pteridophytes (Baraloto et al 2013;Haque et al 2016;Krishnan and Rekha 2021). In contrast, the Cendil heath forest had habitat characteristics that were inversely proportional to the Gurok Beraye tropical rainforest.…”

Abstract. Priambudi AS, Chikmawati T, Sulistijorini, Fakhrurrozi Y. 2022. Diversity and ecology of Pteridophytes in Cendil heath forest and Gurok Beraye tropical rainforest, Belitung, Indonesia. Biodiversitas 23: 4775-4782. The tropical heath forest is a unique ecosystem type characterized by sandy and acidic soils with poor nutrients and water availability, making this ecosystem very vulnerable to disturbances. Yet, knowledge regarding the diversity and ecology of the biological elements of heath forests is still very limited, moreover, information on lesser-known plant groups, such as pteridophytes. Pteridophytes can be used as indicators of the quality of a forest ecosystem since they are cosmopolitan and have an excellent adaptation to various habitats. Belitung Island, Indonesia, is a region with a large proportion of tropical heath forest and small areas of tropical rainforest. There are only a few studies on comparison of the flora of the two ecosystem types on Belitung Island. This research aimed to compare the diversity and the ecology of pteridophytes that grow in the Cendil heath forest and the Gurok Beraye tropical rainforest, Belitung Island. The study used the cruise and the purposive sampling methods to record all pteridophytes within the sampling plots measuring 5 x 5 m alternately located on the right and left of line transects with a length of 50 meters each transect. Ecological data were calculated using the Important Value Index (IVI), Shannon-Wiener diversity index, Margalef richness index, Evenness index, Sorensen similarity index, Morisita distribution index, and Canonical Correspondence Analysis. The results showed that as many as 31 species of pteridophytes belonged to 14 families in the Cendil heath forest and Gurok Beraye tropical rainforest. The pteridophytes found in the Gurok Beraye tropical rainforest were higher (30 species) than that in the Cendil heath forest (9 species). There was high dominance of a few species in the Cendil heath forest due to the presence of three species with high IVI, namely Dicranopteris linearis, Palhinhaea cernua and Dicranopteris splendida. In contrast, pteridophytes in the Gurok Beraye tropical rainforest were evenly distributed with no high dominance species. Environmental parameters that affected the diversity and abundance of pteridophytes included temperature, light intensity, humidity, and altitude.

The microbiome is the synchronised congregation of millions of microbial cells in a particular ecosystem. The rhizospheric, phyllospheric, and endospheric microbial diversity of lower groups of plants like pteridophytes, which includes the Ferns and Fern Allies, have also given numerous alternative opportunities to achieve greener and sustainable agriculture. The broad-spectrum bioactivities of these microorganisms, including bioremediation of heavy metals (HMs) in contaminated soil, have been drawing the attention of agricultural researchers for the preparation of bioformulations for applications in climate-resilient and versatile agricultural production systems. Pteridophytes have an enormous capacity to absorb HMs from the soil. However, their direct application in the agricultural field for HM absorption seems infeasible. At the same time, utilisation of Pteridophyte-associated microbes having the capacity for bioremediation have been evaluated and can revolutionise agriculture in mining and mineral-rich areas. In spite of the great potential, this group of microbiomes has been less studied. Under these facts, this prospective review was carried out to summarise the basic and applied research on the potential of Pteridophyte microbiomes for soil bioremediation and other agricultural applications globally. Gaps have also been indicated to present scopes for future research programmes.

Numerous photoprotective techniques have been employed to successfully shield against the harmful effects of ultraviolet radiation. Current photoprotective techniques have limitations due to the amount of topical application, insufficient physical protection, and adverse responses to topical agents. A newer option that offers a promising defense against solar radiation is systemic agents, the well-researched Polypodium leucotomos is significant in this category, and several studies have found to be effective ―oral sunscreenǁ. Polypodium leucotomos (PL) extract has gained significant attention as a potential therapeutic agent in the field of dermatology, particularly in the photoprotection and management of various dermatological conditions. This abstract provides a comprehensive overview of the mechanism, safety, and efficacy of Polypodium leucotomos extract in relation to photoprotection and dermatological conditions. Our primary aim is to review Polypodium leucotomos' photoprotective results from studies that are currently available, and our secondary goal is to describe Polypodium leucotomos' applications in different dermatological conditions. Articles discussing Polypodium leucotomos uses in photoprotection and dermatologic conditions are searched and downloaded from publicly available databases such as PubMed, JSTOR, PLOS, Science Direct, DOAJ, Google Scholar, and Web of Science and evaluate the outcomes of the Polypodium leucotomos effect. Firstly, we delve into the mechanisms underlying the photoprotective properties of PL extract. Extensive research has demonstrated that PL extract exerts its protective effects through multiple pathways, including antioxidant activity, DNA repair stimulation, immunomodulation, and inhibition of inflammatory mediators. These mechanisms collectively contribute to the prevention of photodamage, such as sunburn, DNA damage, and photoaging. Furthermore, we explore the safety profile of PL extract, emphasizing its remarkable tolerability and minimal adverse effects reported in clinical studies. The absence of systemic absorption and its compatibility with other treatments make PL extract a promising option for long-term use in photoprotection and dermatological care. A promising alternative to traditional photoprotection may be Polypodium leucotomos. Additional thorough clinical trials are necessary to ascertain its role and effectiveness more accurately. The efficacy of PL extract in managing various dermatological conditions is also discussed. Multiple studies have demonstrated its beneficial effects in conditions such as vitiligo, melasma, psoriasis, and atopic dermatitis. The anti-inflammatory and immunomodulatory properties of PL extract have shown promise in reducing disease severity, improving skin symptoms, and enhancing the quality of life for patients. Additionally, the abstract highlights the potential future directions and areas of research for PL extract. Investigating its combination therapy with other photoprotective agents, exploring optimal dosage regimens, and further elucidating the molecular mechanisms are areas that warrant attention. In conclusion, this abstract provides an insightful overview of the mechanisms, safety, and efficacy of PL extract in photoprotection and dermatological conditions. The remarkable properties of PL extract, combined with its favorable safety profile, position it as a promising therapeutic intervention in dermatology. Further research and clinical trials are needed to fully exploit its potential and establish its place in the management of various skin conditions.
