Article Synopsis
- Ecological engineering of soil formation in iron ore tailings is a new method aimed at sustainable rehabilitation by creating stable soil aggregates from fine textured tailings.
- The process involves microbial and rhizosphere interactions that help form aggregates through the binding of mineral particles with organic materials, initially from decomposed organic matter.
- The stability of these aggregates is enhanced by nanosized minerals created during the weathering of iron-bearing minerals, driven by the biogeochemical activities of early plant growth, leading to a proposed model for developing resilient soil structures in tailings.
The formation of water-stable aggregates in finely textured and polymineral magnetite Fe ore tailings is one of the critical processes in eco-engineering tailings into soil-like substrates as a new way to rehabilitate the tailings. Organic matter (OM) amendment and plant colonization are considered to be effective in enhancing water-stable aggregation, but the underlying mechanisms have not yet been elucidated. The present study aimed to characterize detailed changes in physicochemistry, Fe-bearing mineralogy, and organo-mineral interactions in magnetite Fe ore tailings subject to the combined treatments of OM amendment and plant colonization, by employing various microspectroscopic methods, including synchrotron-based X-ray absorption fine structure spectroscopy and nanoscale secondary ion mass spectroscopy.

R. gardneri is thought to be linked via a common mycorrhizal fungus to co-occurring autotrophic shrubs, but there is no experimental evidence to support this supposition.

- This study focused on identifying fungal endophytes from six orchid species in southeastern Queensland using methods like ITS-PCR and RFLP analysis, revealing five main fungal groupings.
- The research indicated that the endophytes of three Pterostylis species likely belong to the Thanatephorus genus, while a fungus from Acianthus spp. showed a close genetic relationship to Epulorhiza repens.
- Findings also suggested that fungal partners exhibit specificity within the orchid genera Acianthus, Caladenia, and Pterostylis, with some species showing different colonization abilities.
