Data for: Positive feedbacks with ectomycorrhizal fungi drive aboveground traits in rare plant species

Dataset was initially utilized in Wooliver et al. 2018 (https://doi.org/10.1111/1365-2745.12983); data from this paperwere recategorized through the addition of rarity levels and reanalyzed to address untested hypotheses and provide new results unrelated to Wooliver et al. 2018. The csv file titled "raw_data" provides information about the biomass, percent ectomycorrhizal (ECM), and percent DSE colonization among 14 species of Tasmanian Eucalyptus varying in rarity levels. Within the data, a rarity level 8 is representative of common species. The other two data files represent the calculated effect sizes of biomass and ECM colonziation in phylogenetically similar (con_to_same) and distant mixtures (con_to_opp)compared to conspecific soil conditions. Within the "con_to_same" and "con_to_opp" files, hedge_g_biomass represents the effect size of biomass and hedge_g_ecm represents the effect size of ecm. These datasets are used to test the hypotheses: 1) Total plant biomass, ECM colonization, and DSE colonization vary based on the rarity of plant host; 2) Plant species inoculated by conditioned soil varying in phylogenetic relatedness (conspecific, similar, distant) demonstrate differences in total plant biomass, ECM colonization, and DSE colonization. To understand potential mechanistic drivers of hypotheses 1 and 2, we also hypothesized that: 3) The difference between the total plant biomass of species in conspecific soil versus same lineage or opposite lineage soil is related to differing rates of ECM and DSE colonization.本数据集最初应用于Wooliver等人2018年的研究（https://doi.org/10.1111/1365-2745.12983）；本研究对该论文中的数据进行了重新分类，新增了稀有度层级，并开展了重新分析，旨在验证尚未被检验过的假说，同时得到与Wooliver等人2018年研究无关的全新研究结果。名为"raw_data"的CSV文件包含了14种塔斯马尼亚桉属（Eucalyptus）植物的生物量、外生菌根（ectomycorrhizal, ECM）定殖百分比以及深色有隔内生真菌（dark septate endophyte, DSE）定殖百分比数据，这些物种的稀有度层级各不相同。在该数据集中，稀有度层级8代表常见物种。其余两个数据文件则给出了相较于同种土壤条件下，系统发育亲缘关系相近（con_to_same）与较远（con_to_opp）的混合土壤中，生物量与ECM定殖率的标准化效应量计算结果。在"con_to_same"与"con_to_opp"数据文件中，hedge_g_biomass代表生物量的效应量，hedge_g_ecm代表ECM定殖率的效应量。本数据集用于验证以下两项假说：1）植物总生物量、ECM定殖率与DSE定殖率会随宿主植物的稀有程度发生变化；2）经不同系统发育亲缘关系（同种、近缘、远缘）的驯化土壤接种的植物物种，其总生物量、ECM定殖率与DSE定殖率存在差异。为探究假说1与假说2背后的潜在机制驱动因素，本研究同时提出了假说3：同种土壤与近缘/远缘土壤中植物总生物量的差值，与ECM和DSE定殖率的差异存在关联。
