Table 2

Results of the broken stick model for the abundance rank distribution of Odonata species, calculated for each of the three water types.

Sample	Intercept ±S.E.	Slope ±S.E.	R	Prob.
Streams	4.05 ± 1.75	0.55 ± 0.19	0.37	0.009
Rivers	2.96 ± 1.19	0.26 ± 0.09	0.38	0.008
Ponds	25.27 ± 5.41	-1.02 ± 0.43	-0.33	0.02
Slope of SAD: = 6.22, p (regr): 0.002
(ANCOVA interactions x species rank)
Monte-Carlo Permutation (n = 99999): p<0.0014
