Effects of experimental irrigation and drought on the composition and diversity of soil fauna in a coniferous stand

Supplementary material to Lindberg, N., Engtsson, J. & Persson, T. Effects of experimental irrigation and drought on the composition and diversity of soil fauna in a coniferous stand. Journal of Applied Ecology, 39 (6), 000–000.


Densities m–2 (SE) of Oribatida, Collembola and Enchytraeidae species at Skogaby (n = 4). Abbreviations of the scientific names are used in Fig. 5B of the main text. D, drought; C, control; I, irrigation. P-values of treatment effect according to two-way ANOVA, d.f. = 2,6 (NS = P > 0·05). Within each species/taxon, numbers with different letters are significantly different (Tukey's studentized range test, P < 0·05). Relative abundance rank shifts > 10 between treatments are indicated; – , rank shift < 10; del, not included in the W-test (see text). HGC, high-gradient canister extractor; T, Tullgren funnel; B, Baermann funnel. Because we found clear overall differences in species composition between the treatments in the PCA (see text), the use of a Bonferroni test to correct for the large number of species-wise tests was considered to be unnecessarily rigorous.

*Species found only in Tullgren samples. One individual sampled per treatment corresponds to a mean density of 120 individuals m–2 for HGC samples, 6 individuals m–2 for Tullgren samples and 20 individuals m–2 for Baermann samples. Treatment specificity indicates absence (–) or presence (+) in one of the treatments. Suctobelbella species identified were S. similis and S. acutidens.
