Commonly, normal diffusive behavior is characterized by a linear dependence of the second
central moment on time,⟨ x 2 (t)⟩∝ t, while anomalous behavior is expected to show a …

New technological developments in animal-borne satellite-tracking devices in combination
with increased access to satellite-based environmental data are creating new possibilities …

Background Lévy flights are random walks, the step lengths of which come from probability
distributions with heavy power-law tails, such that clusters of short steps are connected by …

In this chapter we will describe the species-specific swimming and movement patterns of
tunas, billfishes, and large pelagic sharks derived from extensive data sets obtained using …

From the moment an adult fruit fly ecloses, its primary objective in life is to disperse and
locate the source of an attractive food odor upon which to feed and reproduce. The evolution …

We re-evaluate the long standing and widely held belief that ballistic movements (ie straight-
lines movements) outperform Lévy walks when searching for targets that once located are …

We used satellite tags to record the patterns of depth utilisation for four ocean sunfish (Mola
mola) and two leatherback turtles (Dermochelys coriacea) moving in broadly the same area …

Recently it has been found that composite Brownian walk searches are more efficient than
any Lévy walk when searching is non-destructive and when the Lévy walks are not …

This study explores the diffusive properties of human eye movements during a language
comprehension task. In this task, adults are given auditory instructions to locate named …

We study properties of a single-well fourth-order potential perturbed by a periodically
modulated stable noise. Periodic modulation of the stable noise asymmetry results in an …
