Indicator species analysis. Associations were calculated with the Dufrene–Legendre indicator species analysis routine (Indval, indicator value) in R. Significance levels: P ≤ 0.05•; P ≤ 0.01*; P ≤ 0.001**. P values were corrected for multiple comparisons using the false discovery rate (FDR) with the Benjamini–Hochberg method.(XLSX 44 kb)
