Individual swimming bacteria are known to bias their random trajectories in search of food
and to optimize survival. The motion of bacteria within a swarm, wherein they migrate as a …

Ecological theory predicts that animal movement is shaped by its efficiency of resource
acquisition. Focusing solely on efficiency, however, ignores the fact that animal activity can …

It is generally believed that random search processes based on scale-free, Lévy stable jump
length distributions (Lévy flights) optimize the search for sparse targets. Here we show that …

There is now compelling evidence that many organisms have movement patterns that can
be described as Lévy walks, or Lévy flights. Lévy movement patterns have been identified in …

Populations on the edge of an expanding range are subject to unique evolutionary
pressures acting on their life‐history and dispersal traits. Empirical evidence and theory …

The vast majority of travel takes place within cities. Recently, new data has become
available which allows for the discovery of urban mobility patterns which differ from …

To overcome the shortcomings of the algorithm optimization algorithm (AOA), such as its
slow convergence speed and poor global search ability, an improved AOA based on …

With recent technological advances in tracking devices, movements of numerous animal
species can be recorded with a high resolution over large spatial and temporal ranges. This …
