Experimental increase of worker diversity benefits brood production in ants

Table 1 Parameters of the models for egg production over time in the control (n = 23) and treatment (n = 18) colonies

Parameter	Estimate control (± se)	Estimate treatment (± se)	t-value	p-value
a	3.23 ± 0.78	2.95 ± 1.17	−0.24	0.81
b	0.40 ± 0.07	0.12 ± 0.11	1.10	0.27
c	−0.03 ± 0	−0.006 ± 0	−1.52	0.13
d	0.0006 ± 0	0.0001 ± 0	1.63	0.10
e	−0.000004 ± 0	−0.000001 ± 0	−1.56	0.12

The models are based on a quintic function \(y = a*x + b*x^{2} + c*x^{3} + d*x^{4} + e*x^{5}\). y stands for the number of eggs, x is the number of days after setup, and a, b, c, d and e are the parameters estimated by the models
