ABSTRACT Many animals use information from conspecifics to change their behavior in adaptive ways. When a rock ant, Temnothorax albipennis, finds food, she returns to her colony and uses a method called tandem running to lead nestmates, one at a time, from the nest to the food. In this way, naive ants can learn the location of a food source. Less clear is whether they also learn navigational cues that guide them from nest to food, although this is often assumed. We tested this idea by tracing th...

The fitness of group-living animals often depends on how well members share information needed for collective decision-making. Theoretical studies have shown that collective choices can emerge in a homogeneous group of individuals following identical rules, but real animals show much evidence for heterogeneity in the degree and nature of their contribution to group decisions. In social insects, for example, the transmission and processing of information is influenced by a well-organized division...

Signals whose function is solely to coordinate communication are so far known only in human conversations [1] and telecommunication networks [2]. Utterances like “mm-hmm” [3], gestures such as the nodding of one9s head, or “ACK” packets used in Internet protocols to confirm the reception of a message [4] all coordinate communication. Rather than carrying domain-specific information [5−7], these signals are generic acknowledgements used by receivers to control the flow of sender information when ...

The nest structures built by social insects are complex group-level patterns that emerge from interactions among individuals following simple behavioral rules. The theory of complex systems predicts that there is no simple one-to-one relationship between variations in collective patterns and variation in individual behaviors; therefore, it is essential to know how actual behavior evolves to change pattern formation. Here we demonstrate that the evolutionary divergence of termite tunneling patter...

The study of rational choice in humans and other animals typically focuses on decision outcomes, but rationality also applies to decision latencies, especially when time is scarce and valuable. For...

The fitness of group-living animals often depends on the efficiency with which members share information about resources, so that the group can collectively decide how best to allocate its efforts. Theoretical studies have shown that collective choices can emerge from homogeneous individuals following identical rules, but real animals show much evidence for heterogeneity in the degree and nature of their contribution to group decisions. In the social insects, for example, the transmission and pr...

The advantages of group living are partially offset by the cognitive challenges associated with maintaining social boundaries. These challenges can give rise to recognition mechanisms that adaptively integrate information across multiple sensory modalities. The valley carpenter bee, Xylocopa varipuncta, nests in dead wood in large aggregations of up to several dozen nests. This study investigates the proximate mechanisms by which returning foragers quickly and reliably identify their own nest en...
