Table 2. Comparison of alternative models for abundance of arthropods in bulk samples taken pre-treatment and 3 weeks post-treatment.

AIC values indicated the best fitting model included effects of period, habitat, and location, but not treatment.

Model	Res.Df	Likelihood ratio	P(>LR)	AIC.value	delta.AIC
abundance ~ period + habitat + location	89	NA	NA	6795	0
abundance ~ period + habitat + location + treatment	88	11.0	0.92	6826	31
