Table 2.

Models developed to investigate the relationship between the occurrence of parasites detected in wolf scats and ecological factors using datasets of three different wolf populations: PNALM (winter 2006–2007); PNM (winter 2006–2007); YNP (winters 2007–2008 and 2008–2009).

Classes of models	Response variable	Explanatory variables a
1. Overall ecological effects	Infection status b	Pack ID*, wolf density, free-ranging dogs, park ID, diet
	Parasite taxa c
2. Ecological effects separately for directly vs indirectly transmitted parasites	Infection status b	Same as for the models of class 1
	Parasite taxa c
3. Ecological effects separately for selected groups of parasites	Infection status b	Same as for models of class 1
	Parasite taxa c

^aRandom factors in GLMM (Generalised Linear Mixed Models) are marked with *.

^bCode 0 (no parasites detected in a faecal sample) vs 1 (≥1 parasite taxa detected).

^cThe total number of parasite taxa identified in a faecal sample.
