Table 2.

Habitat multilevel pairwise comparisons to test for differences in chemical composition across habitat types (i.e. Urban, Suburban and Rural). Log transformed normalized peak ratio values were used as input. Multilevel pairwise-comparison adjusted P values are shown (p.adjust = ‘fdr’).

Habitat pairs	Df	Sums Of Sqs	F.Model	R2	p.value	p.adjusted
Suburban vs Urban	1	0.143	4.462	0.1333	0.003	0.003
Suburban vs Rural	1	0.829	17.641	0.363	0.001	0.0015
Urban vs Rural	1	0.401	7.646	0.242	0.001	0.0015
