Efficient transportation, a hot topic in nonlinear science 1 , is essential for modern societies
and the survival of biological species. Biological evolution has generated a rich variety of …

The origins of large-scale spatial patterns in biology have been an important source of
theoretical speculation since the pioneering work by Turing (1952) on the chemical basis of …

Most studies describing animal movements have been developed in the framework of
population dispersion or population dynamics, and have mainly focused on movements in open …

We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using
a novel imaging and analysis technique we estimated pheromone concentrations at all …

Amplification processes are an essential component of the collective phenomena observed
in social and gregarious species. In this paper, we tested the hypothesis that a weak …

Many animals take part in flow-like collective movements. In most species, however, the flow
is unidirectional. Ants are one of the rare group of organisms in which flow-like movements …

In many species of group living invertebrates, in particular arthropods, collective decisions
can emerge from the combined actions of individuals and the direct or indirect interactions …

In this paper we present an individual-based model describing the foraging behavior of ants
moving in an artificial network of tunnels in which several interconnected paths can be used …

This study provides a detailed account of the natural history and foraging biology of the
ponerine ant Dinoponera gigantea in a rainforest in north Brazil. The species nests on the …

We experimentally investigated both individual and collective behavior of the Argentine ant
Linepithema humile as they crossed symmetrical and asymmetrical bifurcations in gallery …
