Determinants of species assemblages of insect pests in alpine forest ecosystems of western China

Forest Ecosystems

Table 1 Difference tests for the number of association links and effect sizes for insect pest species among five parts of plant hosts (i.e., leaves, roots, seeds and fruits, trunks, and twigs). Difference represents the minus values of mean number of association links and effect sizes between two specific parts of plant hosts (Part1 minus Part2). The results of this table were shown based on the pairs of two specific parts of plant hosts

Part1	Part2	Number of association links		Effect size
Part1	Part2	Difference	P-values	Difference	P-values
Seed and fruit	Root	19.929	0.023	0.000	0.931
Seed and fruit	Leaf	15.925	0.032	0.002	0.551
