Entomophagous arthropods can provide valuable biological control services, but they need
to fulfill their life cycle in agricultural landscapes often dominated by ephemeral and …

Interest in L évy walks within the context of movement of organisms has recently soared, with
some now referring to this approach as the L évy walk/flight paradigm. The principal …

Throughout evolution, bacteria and other microorganisms have learned efficient foraging
strategies that exploit characteristic properties of their unknown environment. While much …

The size spectrum of an ecological community characterizes how a property, such as
abundance or biomass, varies with body size. Size spectra are often used as ecosystem …

Metastatic cancer cells differ from their non-metastatic counterparts not only in terms of
molecular composition and genetics, but also by the very strategy they employ for …

Together with life-history and underlying physiology, the behavioural variability among fish
is one of the three main trait axes that determines the vulnerability to fishing. However, there …

Mathematical and computational approaches are important tools for understanding
epidemic spread patterns and evaluating policies of disease control. In recent years …

Anomalous diffusion in various complex systems abounds in nature and spans multiple
space and time scales. Canonical characterization techniques that rely upon mean squared …

While evidence for optimal random search patterns, known as Lévy walks, in empirical
movement data is mounting for a growing list of taxa spanning motile cells to humans, there …

We consider a minimal model of persistent random searcher with a short range memory. We
calculate exactly for such a searcher the mean first-passage time to a target in a bounded …
