Table 1.

Values or ranges, where applicable, for the parameters used in models 1 and 2 depicted in Fig. 1

Parameters	Description	Value/range
N	Colony size	250
F	Fraction of active ants	[0.05,0.5]
Q	Quorum threshold	n.a.
f	Fraction of post-quorum reverse tandem running time	n.a.
μ	Rate at which active ants at old nest become scouts (ant − 1 min − 1)	[0.01,0.2]
λ	Rate at which ants following tandem runs become recruiters (ant − 1 min − 1)	0.1
φ	Rate at which passive ants are carried to new nest (ant − 1 min − 1)	0.2
k	Rate at which scouts independently become recruiters (ant − 1 min − 1)	{0.0001,0.001}

Parameter choices for λ, φ and N were taken from the ranges in Pratt et al. (2005).
