Table 2 Comparative analysisof all variables (soil carbon, nitrogen and C:N ratio) among treatments and their multiple comparisons (pairwise comparisons). (T1) native species without Periandra mediterranea and no invasion; (T2) native species plus P. mediterranea and no invasion; (T3) native species plus P. mediterranea and ≤50% invasion; (T4) native species plus P. mediterranea and >50% invasion. Means in bold are significantly different according to the Kruskal-Wallis test at 5% confidence level (p ≤ 0.05) and multiple comparisons by the Nemenyi test.
