Data from: A comparative approach to cooperative transport in ants: individual persistence correlates with group coordination
When groups of ants work together to carry large objects—called cooperative transport—they must form consensus on a travel direction. In many species, groups are unsuccessful at this decision, and deadlock. In other collective decisions, including nest-site selection in honeybees, individuals' enthusiasm or recruitment intensity for a given option affects the selection process. A similar mechanism may be important during cooperative transport in ants and may account for coordination differences among species. Results from theoretical models suggest that individuals' persistence—their reluctance to give up or change their preferred direction—may promote coordination. More persistent individuals formed more successful groups in a theoretical context. As an empirical test of this hypothesis, I examined cooperative transport in four ant species that differ substantially in their group-level coordination, from exceedingly coordinated to rarely successful. I focused on the beginning of transport, evaluating groups' transitions from uncoordinated to successful. I measured two types of persistence at the individual level—total engagement effort and local engagement time—and I measured group coordination for each species. In one species, I also manipulated persistence by adding a force equivalent to infinitely persistent ants to the existing transport groups. Species with more persistent individuals succeeded more often and formed more coordinated transport groups, with more direct paths. Furthermore, adding two infinitely persistent ants to the existing groups seemed to moderately increase their path directness. These results support the hypothesis that high individual persistence promotes group coordination during cooperative transport, and this study informs the mechanisms of emergent coordination.

Data from: Collective strategy for obstacle navigation during cooperative transport by ants
Group cohesion and consensus have primarily been studied in the context of discrete decisions, but some group tasks require making serial decisions that build on one another. We examine such collective problem solving by studying obstacle navigation during cooperative transport in ants. In cooperative transport, ants work together to move a large object back to their nest. We blocked cooperative transport groups of Paratrechina longicornis with obstacles of varying complexity, analyzing groups' trajectories to infer what kind of strategy the ants employed. Simple strategies require little information, but more challenging, robust strategies succeed with a wider range of obstacles. We found that transport groups use a stochastic strategy that leads to efficient navigation around simple obstacles, and still succeeds at difficult obstacles. While groups navigating obstacles preferentially move directly toward the nest, they change their behavior over time; the longer the ants are obstructed, the more likely they are to move away from the nest. This increases the chance of finding a path around the obstacle. Groups rapidly changed directions and rarely stalled during navigation, indicating that these ants maintain consensus even when the nest direction is blocked. Although some decisions were aided by the arrival of new ants, at many key points, direction changes were initiated within the group, with no apparent external cause. This ant species is highly effective at navigating complex environments, and implements a flexible strategy that works for both simple and more complex obstacles.
