Potential and Application of Pteridophytes as Ecological Bioindicators: An Updated Review

Mildawati Mildawati

Abstract

Pteridophytes are essential as bioindicators in environmental quality monitoring and assessment due to their sensitivity to various air, water and soil pollutants. This study aims to review the recent literature on using ferns as bioindicators, focusing on the methodologies applied and results obtained from various case studies. The research method used in this review involved a systematic literature search through reputable scientific databases such as PubMed, Google Scholar, and Web of Science, with related keywords such as "ferns," "bioindicators," "air pollution," "water pollution," and "heavy metals." The studies analyzed showed that ferns such as Pteridium aquilinum, Polystichum setiferum, Adiantum capillus-veneris, and Azolla filiculoides are effective in detecting air pollutants such as sulphur dioxide (SO₂) and nitrogen dioxide (NO₂), as well as heavy metals in water and soil. Research methodologies reported in the literature involve measuring physiological and biochemical parameters, such as chlorophyll content, antioxidant enzyme activity, and analysis of heavy metal content, which provide accurate data on the impact of pollution on ecosystems. Stable isotope analyses have also helped trace pollutant sources and understand complex biogeochemical dynamics in various ecosystems. Results from the review show that ferns have a high sensitivity to pollutants, making them a reliable tool for environmental monitoring. In addition, using molecular techniques such as eDNA enables the identification of microorganism species associated with ferns, providing additional insights into ecosystem health and pollution impacts. The learnings from this case study underline the importance of multidisciplinary approaches and long-term monitoring in bioindicator research. The findings may help develop more effective and sustainable environmental monitoring strategies.
