Results for single-factor MANOVA tests and Bartlett’s tests for homogeneity of variance

Model ID	MANOVA		P	K 2	Bartlett’s test P
	df	F
1	1,57	8.698	<0.001*	0.008	0.931
2	1,38	2.991	0.063	7.175	0.007*
3.1	1,27	11.915	<0.001*	1.718	0.190
3.2	1,23	1.434	0.260	0.781	0.377
4.1	1,28	2.025	0.153	1.430	0.232
4.2	1,13	5.403	0.021*	5.076	0.024*

Statistically significant results (P < 0.05) for both tests are identified with an asterisk. Bartlett’s test for homogeneity of variance was used to analyze differences in variance of δ¹³C_feces (mating season) and δ¹³C_collagen (multi-year)
