Table 2 Proportion of variance explained by considered covariates in the residual co-occurrence models

Effect type	Covariate^a	Normandy, France (n = 36 horses)		Victoria, Australia (n = 141 horses)
Effect type	Covariate^a	Abundance data (%)	Occurrence data (%)	Abundance data (%)	Occurrence data (%)
Fixed effect	Horse age	14.6	12.9	N/A	N/A
	Organ	31.2	23.8	61	48.3
	Worm burden	14.1	10.9	5.4	3.2
Random effect	Horse	12.8	19.1	11.3	26.5
Random effect	Horse × niche	27.3	33.4	22.3	22

Results are shown for two datasets collected in Australia [6] and France [19]
N/A Not available
^aFor each covariate of interest (fixed or random effect), the proportion of variance explained in strongyle species co-occurrence is given for the two model types considered using positive abundance data or presence-absence data
