Data for: Arbuscular mycorrhizal responsiveness of a Canary Island endemic (Artemisia thuscula Cav.): implications for nursery propagation and restoration

Dataset for “Arbuscular mycorrhizal responsiveness of a Canary Island endemic (Artemisia thuscula Cav.): implications for nursery propagation and restoration” This dataset accompanies the Brief Report submitted to Mycorrhiza (2025). It provides summarized data supporting the analyses and figures presented in the manuscript. The study assessed arbuscular mycorrhizal (AM) colonization and edaphic/foliar context of three Artemisia taxa (A. thuscula, A. ramosa, A. reptans) from contrasting volcanic environments in Tenerife (Canary Islands), and evaluated the early responsiveness of A. thuscula seedlings to controlled AM inoculation in nursery conditions. Contents: Table 1: Soil properties (mean, 95% confidence intervals, CI) for three Artemisia taxa (A. thuscula Cav., A. ramosa C. Sm. ex Link, A. reptans C. Sm.) across contrasting sites in Tenerife, Canary Islands. Table S1: Foliar nutrient concentrations of field plants. Table S2: Nursery substrate properties and seedling growth responses (control vs. AM-inoculated). Table S3: Foliar nutrient concentrations of A. thuscula seedlings under both treatments. Figure 1: ardner–Altman estimation plot of growth responses to AM inoculation of Artemisia thuscula Cav. (biomass, length and stem diameter). Figure 1S: Gardner–Altman estimation plots of growth responses to AM inoculation of Artemisia annua L. README: Metadata and explanation of variables. CODEBOOK: Variable names, units and descriptions. File format: All data tables are provided in ODT (LibreOffice) format compatible with common spreadsheet software. Mean values and 95 % CIs were calculated from three replicates per site or treatment. License: Creative Commons Attribution 4.0 International (CC-BY 4.0).
