Previous results found for selection with antagonistic pleiotropy and discrete generations are extended to cases with overlapping generations. In order to do so, protected polymorphism conditions are found for monoecious and dioecious populations when the intrinsic rate of increase, or Malthusian parameter, is not too large in magnitude. Under such conditions, it is shown that recessive deleter...

Evolutionary games have been introduced by Maynard Smith and Price [1973] in the early 70’s with the aim to study the stability of populations in time. In the general model, a population consists of finitely many different types that interact randomly with each other, where each interaction leads to fitness payoffs for each of the types involved. Consequently, the population distribution over t...

The Common-pool resource (CPR) game is a social dilemma where agents have to decide how to consume a shared CPR. Either they each take their cut, completely destroying the CPR, or they restrain themselves, gaining less immediate profit but sustaining the resource and future profit. When no consumption takes place the CPR simply grows to its carrying capacity. As such, this dilemma provides a fr...

The impact of the presence of risk of destructive event on the silvicultural practice of a forest stand is investigated. For that, we consider a model of population dynamics. This model has allowed us to make the comparison without and with risk, and highlight the influence of the presence of risk of destructive event on optimal thinning and optimal rotation period.

The article elaborates on the spatial disaggregation approach of the 1km population density grid created by the European Forum for Geostatistics in a defined study area where accurate population reference data are available. The paper presents an approach to disaggregate the population grid to target resolution of 100m and 500m respectively and describes the evaluation methodology. The resultin...

Model Evolution of Voltage over Time Consider a group of interacting populations of neurons. Equation 1 describes the evolution over time of the membrane voltages for the ith ensemble. Table 1 explains the remaining variables.

This paper describes a fictional questionnaire intended to be completed by applicants to an intentional community devoted to gamifying all aspects of its members’ lives. This format was chosen as a plausible alternative to science fiction tropes that include the population of entire worlds or counties. It was also chosen because the historical motivations for creating intentional communities cl...

Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its flexibility to capture a wide varie...

We study the responses of discretely reproducing populations to periodic fluctuations in three parameters, the carrying capacity and two demographic characteristics of the species (three parameters). We prove that small 2-periodic fluctuations of the three parameters generate 2-cyclic oscillations of the population. We develop a signature function for predicting the responses of populations to ...

This work presents a discrete time model for the dynamics of a size-classified benthic population with planktonic larvae. Recruitment, decoupled from local reproduction by larval dispersal, is represented in the model as an external subsidy to the local population. Analysis of the model reveals the importance of recruitment and growth plasticity in determining the stability of an equilibrium wh...
