We review the general problem of random searches in the context of biological encounters.
We analyze deterministic and stochastic aspects of searching in general and address the …

Biology of Sharks and Their Relatives is an award-winning and groundbreaking exploration
of the fundamental elements of the taxonomy, systematics, physiology, and ecology of …

Glioblastomas are incurable tumors infiltrating the brain. A subpopulation of glioblastoma
cells forms a functional and therapy-resistant tumor cell network interconnected by tumor …

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 …

It is an open question how animals find food in dynamic natural environments where they
possess little or no knowledge of where resources are located. Foraging theory predicts that …

Power‐law frequency distributions characterize a wide array of natural phenomena. In
ecology, biology, and many physical and social sciences, the exponents of these power …

Lévy walks (LW) are superdiffusive and scale‐free random walks that have recently
emerged as a new conceptual tool for modeling animal search paths. They have been …
