Data from: Reduced aboveground tree growth associated with higher arbuscular mycorrhizal fungal diversity in tropical forest restoration

Arbuscular mycorrhizal fungi (AMF) community data in relation to eight of the sites located near the town of Agua Buena (8° 44′ 36″ N, 82° 58′ 04″ W) and Las Cruces Biological Station (8° 47′ 7″ N, 82° 57′ 32″ W) in Coto Brus county in southern Costa Rica. The eight sites included BR, SC, SP, AC, HR, OM, BB, and EC (renamed sites 1-8, respectively, in the published article). AMF community data included: percent colonization of host tree roots; identification of the fungal species associated with trees roots through DNA isolation; and spore density, volume, and identity in both the wet and dry seasons. Data also included average soil characteristics per sites (taken from 2012 dataset) and tree growth (as height and diameter at breast height per year) per tree species and site.

本数据集收录哥斯达黎加南部科托布鲁斯县内，毗邻阿瓜布埃纳镇（8°44′36″ N，82°58′04″ W）与拉斯克鲁斯生物站（8°47′7″ N，82°57′32″）的8处样地的丛枝菌根真菌（Arbuscular Mycorrhizal Fungi, AMF）群落相关数据。该8处样地依次编号为BR、SC、SP、AC、HR、OM、BB及EC（已在发表论文中分别重命名为样地1至8）。本次纳入的AMF群落数据包含：宿主林木根系的菌根定殖率；通过DNA分离技术鉴定与树木根系共生的真菌物种；以及干湿两季的孢子密度、体积与物种鉴定结果。此外，数据集还涵盖各样地的平均土壤理化性质（取自2012年数据集），以及各树种在对应样地的年均树高与胸径生长指标。
