We construct a model of a specialist predator and its prey species for the case of non-
overlapping generations and we assume that the prey obeys to the Allee effect. We observe …

We construct and study a discrete time model describing the conflict interaction between two
complex systems with non-trivial internal structures. The external conflict interaction is based …

Global cooperation becomes more and more important in times of increased environmental
awareness. However, exploiting out-group members allows ethnocentrism to be …

We present a theoretical model of evolution of spatially distributed populations in which
organisms mate with and compete against each other only locally. We show using both …

We consider a one-dimensional chain of sites, appropriate for colonization by a biological
species. The dynamics at each site is subjected to the demographic Allee effect. We …

We investigate a dynamical system of conflict between two systems each of which, in turn,
has an internal conflict. The external conflict and the internal one have different natures. The …

Using a Monte Carlo approach we study the role of inheritance and natural selection in the
dynamics of populations. We show that a population subject to inheritance has a much …

This Letter introduces a new set of rate equations describing migration-driven aggregation
behaviors in job markets with direct foreign immigration. We divide the job market into two …

Abstract The Nicholas-Bailey model was designed to study population dynamics of host-
parasite systems. The model was first developed by Nicholson and Bailey (1935) and …

We consider a one-dimensional chain of identical sites, appropriate for colonization by a
biological species. The dynamics at each site is subjected to the demographic Allee effect …
