“…Dicranopteris communities are beneficial to ecosystems by conserving water and soil in the following ways ( Chen et al, 2016 ; Chen and Chen, 2018 ; Jiang et al, 2019 ). First, the leaves of a Dicranopteris can reduce splash erosion.…”

Rethinking the Ecosystem Functions of Dicranopteris, a Widespread Genus of Ferns

Dicranopteris is an ancient and widespread genus of ferns in pantropical regions. Some species of the genus can form dense thickets, and dominate the understory, which are common and key species in tropical and subtropical ecosystems. However, they were mostly cut or burned in forest management because of forming dense thickets which were considered to interfere with forest regeneration and succession. In the current review, we argue that the Dicranopteris species which are able to rapidly colonize barren areas may contribute to ecosystem recovery, resistance to environmental stress, and succession control. Rapid colonization involves prolific spore production, rapid clonal growth, the generation of high surface cover, and the ability to fill gaps; stress resistance includes resistance to abiotic stress, and the ability to reduce soil erosion from rainfall, alien species invasion, and soil contamination and toxicity; and succession facilitation consists of carbon and nutrient sequestration in soil, moderation of the microclimate, alteration of the soil microbial and faunal communities, and determination of which plant species to be established in the next successional stage. All of these ecosystem functions may be beneficial to ecosystem resilience. We expect that the distribution of Dicranopteris will expand in response to global warming, changes in precipitation patterns, increases in soil pollution, deforestation, and land degradation. We recommend that Dicranopteris, as a pioneer fern and a valuable component of tropical and subtropical ecosystems, needs more attention in future research and better management practices to promote forest regeneration and succession.

“…If D. linearis and P. simplex present a high REE accumulation potential, they are subordinate to very specific climates 35 and are also sensitive to microclimate and soil factors. 36 To our knowledge, the publications concerning these ferns only mention naturally occurring plants and never refer to intentional cultivation. These cultivation condition restrictions, notably to subtropical rain forests, may constitute a drawback in the context of phytoremediation or agromining, if the REEcontaminated site is under a temperate or cold climate, under which these plants would hardly grow.…”

Rare earth elements (REEs) are strategic metals strongly involved in low-carbon energy conversion. However, these emerging contaminants are increasingly disseminated into ecosystems, raising concern regarding their toxicity. REE-accumulating plants are crucial subjects to better understand REE transfer to the trophic chain but are also promising phytoremediation tools. In this analysis, we deciphered REE accumulation sites in the REE-accumulating fern Dryopteris erythrosora by synchrotron X-ray μfluorescence (μXRF). This technique allows a high-resolution and in situ analysis of fresh samples or frozen-hydrated cross sections of different organs of the plant. In the sporophyte, REEs were translocated from the roots to the fronds by the xylem sap and were stored within the xylem conductive system. The comparison of REE distribution and accumulation levels in the healthy and necrotic parts of the frond shed light on the differential mobility between light and heavy REEs. Furthermore, the comparison emphasized that necrotized areas were not the main REE-accumulating sites. Finally, the absence of cell-to-cell mobility of REEs in the gametophyte suggested the absence of REE-compatible transporters in photosynthetic tissues. These results provide valuable knowledge on the physiology of REE-accumulating ferns to understand the REE cycle in biological systems and the expansion of phytotechnologies for REE-enriched or REE-contaminated soils.

Rare earth elements, particularly middle and heavy rare earth, are among the most valuable resources in the pursuit of a greener economy. The production of middle and heavy rare earth elements heavily relies on ion adsorption, which constitutes over 80% of global output and is centered in southern China. Unfortunately, the extensive mining activities have led to severe environmental pollution, resource depletion, and risks to human health. In contrast, biochar application offers a cost-effective and efficient phytoremediation solution. However, existing literature on the biochar application in IAT-Res mine tailings is limited. In this paper, we conducted a literature review and summarized the contaminations in the ion adsorption mine tailings, as well as explored the potential of using biochar to remediate contaminations. We aim to raise interest and encourage further research on utilizing biochar for pollution remediation in ion adsorption rare earth mine tailings. By effectively managing contamination, this approach can contribute to the sustainable supply of ion adsorption rare earth elements while ensuring their long-term viability.
