Spatially extended population dynamics models that incorporate demographic noise serve
as case studies for the crucial role of fluctuations and correlations in biological systems …

Lotka's seminal work (Lotka AJ, Proc. Natl. Acad. Sci. USA, 6 (1920) 410)" on certain
rhythmic relations" is already one hundred years old, but the research activity about pattern …

We study a nonhierarchical tritrophic system, whose predator-prey interactions are
described by the rock-paper-scissors game rules. In our stochastic simulations, individuals …

We study generalised rock–paper–scissors models with an arbitrary odd number N≥ 5 of
species, among which n are weak, with 2≤ n≤(N− 1)/2. Because of the species' weakness …

Competing strategies in an evolutionary game model, or species in a biosystem, can easily
form a larger unit which protects them from the invasion of an external actor. Such a …

We revisit the problem of the predominance of the “weakest” species in the context of Lotka-
Volterra and May-Leonard formulations of a spatial stochastic rock-paper-scissors model in …

When faced with an imminent risk of predation, many animals react to escape consumption.
Antipredator strategies are performed by individuals acting as a group to intimidate …

A balanced ecosystem with coexisting constituent species is often perturbed by different
natural events that persist only for a finite duration of time. What becomes important is …

The prototype of a cyclic dominant system is the so-called rock-scissors-paper game, but
similar relation among competing strategies can be identified in several other models of …

Antipredator behavior is present in many biological systems where individuals collectively
react to an imminent attack. The antipredator response may influence spatial pattern …
