The data, presented here, come from samples collected during three research projects which aimed to assess the impact of land-use type on Arbuscular Mycorrhizal Fungi (AMF) diversity and community composition in pastures of Terceira Island (Azores, Macaronesia, Portugal) and also in the native forest of two Azorean Islands (Terceira and São Miguel; Azores, Macaronesia, Portugal). Both projects contributed to improving the knowledge of AMF community structure at both local and regional scales.
Little is known on the AMF communities from Azores islands and this study reports the first survey in two Azorean Islands (Terceira and São Miguel). A total of 18,733 glomeromycotan spores were classified at the species level from 244 field soil samples collected in three different habitat types - native forests (dominated by and ), semi-natural and intensively-managed pastures. Thirty-seven distinct spore morphotypes, representing ten glomeromycotan families, were detected. Species of the family dominated the samples, with 13 species (38% of the taxa), followed by (6 spp.), (4 spp.), (3 spp.), (3 spp.), (3 spp.), and , both with the same number of AMF species (2 spp.), (1 sp.) and (family insertae sedis). Members of the family occurred almost exclusively in the native forests especially associated with the rhizosphere, while members of family showed a high tendency to occupy the semi-natural pastures and the native forests of . Members of family were broadly distributed by all types of habitat which confirm the high ecological plasticity of this AMF family to occupy the more diverse habitats.
本文所呈现的数据来自三个研究项目收集的样本，这些项目旨在评估土地利用类型对亚速尔群岛（葡萄牙马卡罗尼西亚自治区）特塞拉岛牧场以及亚速尔群岛两个岛屿（特塞拉岛和圣米格尔岛；葡萄牙马卡罗尼西亚自治区）原生森林中丛枝菌根真菌（AMF）多样性和群落组成的影响。这两个项目都有助于增进对地方和区域尺度上AMF群落结构的了解。
关于亚速尔群岛的AMF群落，人们了解甚少，本研究报告了在亚速尔群岛两个岛屿（特塞拉岛和圣米格尔岛）的首次调查。从三种不同栖息地类型（原生森林（以 和 为主）、半自然和集约管理牧场）采集的244份田间土壤样本中，共鉴定出18733个球囊霉门孢子的物种水平分类。检测到37种不同的孢子形态类型，代表10个球囊霉门科。 科的物种在样本中占主导地位，有13种（占分类单元的38%），其次是 科（6种）、 科（4种）、 科（3种）、 科（3种）、 科（3种）、 科和 科，两者的AMF物种数量相同（2种）、 科（1种）和 科（科位置未定）。 科的成员几乎只出现在原生森林中，尤其与 的根际相关，而 科的成员表现出高度倾向于占据半自然牧场和 的原生森林。 科的成员广泛分布于所有类型的栖息地，这证实了该AMF科具有很高的生态可塑性，能够占据更多样化的栖息地。
