Models for the behavior of ants and pedestrians are studied in a unified way in this paper. Each ant follows pheromone … put by preceding ants, hence creating a trail on the ground, while pedestrians also try to follow others in a crowd for … average speed of the ants on their density, which can be well analyzed by the zero-range process. We also show that this …

Innate vision-based aversions to model and mimic were investigated using a mimicry system in which the models were ants … group, the "ordinary salticids" as predators. The mimics considered belonged to another group, salticids that resemble ants … of dead arthropods (ants, ant mimics, and an array of non--ant-like species) mounted in a lifelike posture. When …

Jumping spiders (Salticidae) usually avoid ants, but some species within this family single out ants as preferred prey …, while others (especially the species in the genus Myrmarachne) are Batesian mimics of ants. Field records show that ant …

Alternative models of territoriality are based on contrasting assumptions about the behavioral processes determining territory size. In a series of controlled field experiments on the fire ant Solenopsis invicta, I tested whether territory size is affected by the availability of food, as...

, even when the active ants organizing the move do not compare sites. This collective ability depends on a quorum rule used … by ants assessing a candidate site. Only when the site's population has surpassed a threshold do they switch from slow … recruitment of fellow active ants by tandem runs to rapid transport of the majority of the colony. Here, I show that ants perceive …

Delay Tolerant Networks (DTNs) are characterized by the lack of contemporaneous paths between any source and destination node. As a basic forwarding strategy, nodes may flood their bundles to every encountered node. This results in congestion and unnecessarily consumes precious network...
