Evolutionary game theory is an increasingly important way to model the evolution of biological populations. Many early models were in the form of matrix games, or bimatrix games in asymmetric situations when individuals occupy distinct roles within the contest, where rewards are accrued through independent contests against random members of the population. More recent models have not had the si...

Regional dimensions and trends in population aging: Russia/Eastern Europe Population aging is a global phenomenon and countries of Eastern European also experience rapid increase in the proportion of older people. The proportion of elderly people in the Eastern Europe is currently lower than in the European region as a whole. However this population aging is expected to continue over the next f...

The mechanism behind the growth and development of tumors is intensively studied using several mathematical approaches that rely on linear and non-linear techniques to model the cell population dynamics to better understand the development and progression of cancer. In this paper, we study the progression of a type of malignant tumors characterized by the stem-differentiation hierarchy. Two mai...

The recent biological theory of adaptive dynamics [6,9] proposes a description of the long term evolution of an asexual population by putting emphasis on the ecological interactions between individuals, in contrast with classical population genetics models which focus on the genetic structure of the population. The basic models are individual-based models in which the population dynamics is pre...

This study was conducted to collect comprehensive identification about Markhoz goat population and to simulate past dynamics of the population under its living conditions.Census data of the population size and the required parametersfor the simulation modelwere obtained frompublished data or were collected in its habitat in the last 3 years. In this study, past population dynamics and expected ...

The study examined the influence of population as proximate cause of wetland dynamics in the lower Ogun river basin of southwestern, Nigeria. Both primary and secondary data were used for the study. The primary data included 100 questionnaires administered and distributed among the fadama users group representing 10% of the estimated population of the group. Satellite images of years 1972, 1984...

The population dynamics of predator-prey systems in the presence of patch-specific predators are explored in a setting where the prey population has access to both habitats. The emphasis is in situations where patch-prey abundance drives prey-dispersal between patches, with the fragile prey populations, that is, populations subject to the Alee effect. The resulting four-dimensional model’s math...
