Relative colony efficiency and simulation results for = 0.5 in different behavioural regions when varying
and b for the SRT-SL and SL model.
The simulation results of the SL model represent the evolution of engagement levels in Task 1 among the young (green) and old (purple) sub-populations. Engagement levels are defined as the fraction of the subpopulation engaging in Task 1. The simulation results of the SRT-SL model show the evolution of worker thresholds for Task 1 for the young (green) and old (purple) sub-populations. The simulation results of the SRT-SL model are also represented to show the evolution of action probabilities towards Task 1 among the young (green) and old (purple) sub-populations. The histograms illustrate the fraction of individuals at different levels of action probability towards Task 1 for young and old sub-populations in green and purple, respectively. Bar widths reflect chosen bin sizes for visualization. The simulations correspond to different environmental settings: a) b = 2, ; b) b = 20,
; c) b = 20,
; d) b = 20,
