Table 2.
Hub genera for the 4 land uses: the table summarizes the specific hubs for each land use and indicates the average degree of the genera for each of the land uses, the statistical difference with the other genera in the respective land use (given by a Kruskal-Wallis pairwise test) and, in parenthesis, the ranking of each genus among the most connected genera for the land use.

Letters indicate differences of degree between nodes within each land use. They are provided by Pairwise Kruskal-Wallis Rank Test corrected by Bonferroni method.
