Spatial structure and nest demography reveal the influence of competition, parasitism and habitat quality on slavemaking ants and their hosts

Table 2 Comparison of different aspects on a finer and coarser scale.

	Spatial scales
	Fine	Coarse
Spatial pattern	Clumped	Regular
Do slavemaker colonies reside next to host colonies?	No spatial correlation *	Yes, but only in WV
Are host species correlated in space (Bav.)?	No correlation	Yes, negatively correlated
Do slavemaker colonies prefer one of the host species (Bav.)? **	No correlation	No correlation
Does competition/density affect life-history of host colonies (Bav.)?	Yes ***	No

* No spatial correlation for the 1^st to 6^th nearest host.
** See Additional File 3 for this analysis.
*** When testing for the effect of NND vs. the number of colonies in each plot on number of workers and total production.
