Table 1 Results of permutation analysis to relate through RDA the number of A. dealbata´s seeds captured in the river with (A) presence of adult individuals of the same species at each site and (B) hydraulic characteristics at each sampled point. Significant results are highlighted in bold

From: Rivers as a potential dispersing agent of the invasive tree Acacia dealbata
