“…Spores are formed on the lateral side of the sporiferous saccule neck and are globose to ellipsoidal. The spores can be hyaline, yellow, or reddish-yellow, with a size ranging from 100 to 400 μm [14]. The rupture of the hyphal tip leaves a small hole called a cicatrix.…”

Critical lands are formed after landslides due to the erosion and stripping of the surface soil in the depletion zone and the formation of accumulation zones, requiring remediation efforts. Indigenous arbuscular mycorrhizal fungi help rehabilitate degraded lands, including post-landslide sites, by adapting to native soil conditions. This study investigates mycorrhiza’s presence in post-landslide areas with sandy silt in Cililin and clayey silt in Citatah. Soil samples are collected at 30 cm depth using a corer near Dysoxylum macrocarpum in Citatah and Gmelina arborea in Cililin. Mycorrhiza isolation involves wet sieving and centrifugation. Local mycorrhiza genera identified are Glomus, Gigaspora, Acaulospora, and Scutellospora. Sandy silt soil 2 exhibits the highest spore density of 178 per 100 grams, while clayey silt soil 1 has the lowest density of 148 per 100 grams. Glomus dominates in sandy silt with a 93 per 100 grams concentration and a 38–45 µm size. Scutellospora is scarce in clayey silt, with only 1 per 100 grams, 90-170 µm size. Isolated mycorrhiza can serve as compatible and adaptive inoculum. The discovery of mycorrhiza tolerant to post-landslide conditions is expected to play an important role in the remediation process of critical lands caused by landslides.

“…Furthermore, the importance value (IV) of ECM fungi was determined by calculating the average of the RF and RA. A dominant fungus is defined as a species with an IV ≥ 50, a common fungus is defined as a species with 10% < IV < 50%, and a rare fungus is defined as a species with an IV ≤ 10% [67].…”

To explore the contribution of microorganisms to forest ecosystem function, we studied the ectomycorrhizal (ECM) fungal and soil bacterial community of the five typical tree species (Pinus massoniana, PM; Castanopsis carlesii, CC; Castanopsis eyrei, CE; Castanopsis fargesii, CF; and Keteleeria cyclolepis, KC) at the Junzifeng National Nature Reserve. The results indicated that the ECM fungal and soil bacterial diversity of CC and CF was similar, and the diversity rates of CC and CF were higher than those of PM, CE, and KC. Cenococcum geophilum and unclassified_Cortinariaceae II were the most prevalent occurring ECM fungi species in the five typical tree species, followed by unclassified_Cortinariaceae I and Lactarius atrofuscus. In bacteria, the dominant bacterial genera were Acidothermus, Bradyrhizobium, Acidibacter, Candidatus_Solibacter, Candidatus_Koribacter, Roseiarcus, and Bryobacter. EMF fungi and soil bacteria were correlated with edaphic factors, especially the soil pH, TP, and TK, caused by stand development. The results show that the community characteristics of ECM fungi and bacteria in the typical tree species of the Junzifeng National Nature Reserve reflect the critical role of soil microorganisms in stabilizing forest ecosystems.

“…The intricate associations between P. aquilinum and fungi exemplify a compelling instance of ecological symbiosis. Bracken fern engages in mutualistic mycorrhizal relationships with both arbuscular mycorrhizal and ectomycorrhizal fungi, offering nutrients, pathogen protection, and support for seedling growth and establishment [ 49 , 50 , 51 ].…”

Bracken fern (Pteridium aquilinum (L.) Kuhn) is ubiquitous and acts as a cosmopolitan weed in pastures and similar environments. Despite its historical uses, it presents risks due to toxicity. This study, conducted in the second half of 2023, aimed to assess the environmental and health hazards of P. aquilinum, primarily focusing on its carcinogenic compound, ptaquiloside. The literature was comprehensively reviewed using diverse databases, including PubMed, Web of Science, Scopus, and Google Scholar. Information was synthesized from original research articles, meta-analyses, systematic reviews, and relevant animal studies. Animals grazing on bracken fern face annual production losses due to toxin exposure. The substantial impact on biodiversity, animal health, and human well-being arises from the presence of ptaquiloside and related compounds in milk, meat, and water, along with the increasing global prevalence of P. aquilinum and its swift colonization in acidic soil and fire-damaged areas. The objectives were to identify major bioactive compounds and explore their effects at molecular, cellular, pathological, and population levels. Various cooking techniques were considered to mitigate toxin exposure, although complete elimination remains unattainable. Therefore, the findings emphasize the need for cautious consumption. In conclusion, continued research is necessary to better understand and manage its environmental and health implications.
