Factors influencing the reovery of orchids and their mycorrhizal fungi in the post-mining landscape.

采后景观中兰花及其菌根真菌恢复的影响因素。澳大利亚陆生兰花是非常容易受到干扰后，土壤真菌多样性的减少，由于其高度特定的协会与土壤真菌。本研究将探讨铝土矿开采后，在恢复贾拉森林植被的过程中，菌根真菌多样性和空间变异性如何随时间变化。菌根真菌和其他土壤和生境因素对恢复铝土矿土壤中兰花分类多样性和生境偏好的影响将进行调查。采矿后的环境也将与未受干扰的贾拉森林进行对比，以了解为什么一些兰花在这些环境中很常见，而另一些则很罕见。

Factors influencing the reovery of orchids and their mycorrhizal fungi in the post-mining landscape. Australian terrestrial orchids are highly vulnerable to reductions in soil fungus diversity after disturbance, due to their highly specific associations with soil fungi. This project would investigate how mycorrhizal fungal diversity and spatial variability changes with time during restoration of jarrah forest vegetation after bauxite mining. The impact of mycorrhizal fungi and other soil and habitat factors on orchid taxonomic diversity and habitat preferences in rehabilitated bauxite mine soils will be investigated. The post-mining environment will also be contrasted with undisturbed jarrah forest to understand why some orchids are common and others rare in these environments.
