Native arbuscular mycorrhizal fungi respond to rehabilitation in iron ore mining areas from the Eastern Brazilian Amazon

The aim of this work was to evaluate the impact of gypsum mining on the occurrence and diversity of arbuscular mycorrhizal fungi (AMF). Soil samples were collected in the rainy and dry periods in four areas of a gypsum mine: native preserved "caatinga" (NC); mine vicinity (MS); reject area (RA); interface between the reject area and an area of "caatinga" degraded by mining (IN). Forty two plant species were identified in these areas; some were not found in both collection periods. Thirty six taxa of AMF were identified: 31 in the rainy and 31 in the dry period, with different species composition. Mining activity reduced diversity of plants and of AMF in the three mining areas when compared to NC. Plant similarity indexes were low between NC and the degraded areas. Similarity among AMF species was lower in the rainy period and between NC and the ones affected by mining. Glomus intraradices, Glomus sp.1 and Paraglomus occultum were the most common AMF, showing tolerance of edaphic conditions in the impacted areas. These species should be further tested in programs of revegetation of similar gypsum mining degraded areas.

Abstract. Tuheteru FD, Husna, Albasri, Arif A, Wulan SA, Kramadibrata K. 2019. Arbuscular mycorrhizal fungi associated with adaptive plants in gold mine tailing. Biodiversitas 20: 3398-3404. Arbuscular mycorrhizal fungi (AMF) are fungi from division Glomeremycota within the kingdom Fungi, which have a broad ecological range and symbiosis with a variety of vegetations, including vegetations in gold post-mining areas or gold tailings. The study of identifying types of AMF in gold tailings in Southeast Sulawesi is still limited. The purpose of this study was to identify the types of AMF in the rhizosphere of adaptive plants in gold tailings land in Bombana District, Southeast Sulawesi. Soil samples were collected from adaptive plants in Perseroan Terbatas (PT) Panca Logam Makmur, Bombana District, Southeast Sulawesi Province, Indonesia. AM Fungi spores were isolated and identified based on their morphological characteristics (shape, size, color, attached hyphae, and spore ornamentation). Five types of AMF were identified, namely Glomus aggregatum, Sclerocystis sinuosa, Acaulospora scrobiculata, A. tuberculata, Scutellospora pellucida, and two genera that had not been identified up to species, Glomus sp. and Scutellospora sp. In addition to spores, the symbiosis of AM Fungi with adaptive plants was also demonstrated by the structure of AM Fungi in plant roots with a rate of 74% colonization. S. pellucida and S. sinuosa were recorded as new species in Indonesia and Sulawesi, respectively. While A. tuberculata is a type of AMF that enriches AMF diversity in Southeast Sulawesi.
