Random walk is a fundamental concept with applications ranging from quantum physics to
econometrics. Remarkably, one specific model of random walks appears to be ubiquitous …

This review examines intermittent target search strategies, which combine phases of slow
motion, allowing the searcher to detect the target, and phases of fast motion during which …

An optimal search theory, the so-called Lévy-flight foraging hypothesis, predicts that
predators should adopt search strategies known as Lévy flights where prey is sparse and …

Chemokines have a central role in regulating processes essential to the immune function of
T cells,,, such as their migration within lymphoid tissues and targeting of pathogens in sites …

Many free-ranging predators have to make foraging decisions with little, if any, knowledge of
present resource distribution and availability. The optimal search strategy they should use to …

The study of animal foraging behaviour is of practical ecological importance, and
exemplifies the wider scientific problem of optimizing search strategies. Lévy flights are …

Recent advances in spatial ecology have improved our understanding of the role of large‐
scale animal movements. However, an unsolved problem concerns the inherent …

Large scale analysis and statistics of socio-technical systems that just a few short years ago
would have required the use of consistent economic and human resources can nowadays …

This book explains the quantitative reasoning required by the fractional calculus applied to
complex physical, social, and biological phenomena. Fractional calculus is inextricably …

Our limited intuition of the small‐scale world of the plankton has biased the way we describe
and understand ocean ecology. Classical approaches consider fluxes of energy and matter …
