Dryland soils Raw sequence reads

We characterised the bacterial and fungal communities of biological soil crusts (biocrust; 0–1 cm depth) and the subsurface soil (1–2 cm depth) inan area typical of lightly grazed Kalahari rangelands, composed of grasses, shrubs, andtrees. Biocrust microbial community structure is likely to affect functioning of soils (e.g. resistance to erosion, carbon storage) but to date very little is known about the microbes in biocrusts. This study reveals in detail for the first time the bacterial and fungal communities of biocrusts in the Kalahari.本研究对以草本、灌木和乔木为主要植被的轻度放牧卡拉哈里（Kalahari）典型牧场区域内的生物土壤结皮（biological soil crusts，biocrust；0~1 cm深度）及下层土壤（1~2 cm深度）的细菌与真菌群落进行了解析。生物结皮的微生物群落结构可能会影响土壤生态功能（如抗侵蚀能力、碳储存能力），但迄今为止学界对生物结皮内的微生物仍所知甚少。本研究首次详细揭示了卡拉哈里地区生物土壤结皮中的细菌与真菌群落组成。
