The maintenance of genetic variation in a spatially heterogeneous environment has been one of the main research themes in theoretical population genetics. Despite considerable progress in understanding the consequences of spatially structur...

Although perturbations from a stable equilibrium must ultimately vanish, they can grow initially, and the maximum initial growth rate is called reactivity. Reactivity thus identifies systems that may undergo transient population surges or d...
Modeling toxoplasmosis spread in cat populations under vaccination [0.03%]
接种疫苗情况下布氏梨形鞭毛虫在猫群中传播的建模分析研究

In this paper we present an epidemiological model to study the transmission dynamics of toxoplasmosis in a cat population under a continuous vaccination schedule. We explore the dynamics of toxoplasmosis at the population level using a math...

A fast algorithm for computing recombination is developed for model organisms with selection on haploids. Haplotype frequencies are transformed to marginal frequencies; random mating and recombination are computed; marginal frequencies are ...
Generous cooperators can outperform non-generous cooperators when replacing a population of defectors [0.03%]
当取代一群欺骗者时，乐于合作的个体可以胜过不乐于合作的个体

The evolution of cooperation has been a major challenge in evolutionary biology. Unconditional cooperators who help others at a cost to themselves are exploited by defectors who enjoy the benefits without any help in return. It has been arg...
Extinction conditions for isolated populations affected by environmental stochasticity [0.03%]
受环境随机性影响的孤立种群灭绝条件

Vicenç Méndez et al.
We determine the critical patch size below which extinction occurs for populations living in one-dimensional habitats surrounded by completely hostile environments in the presence of environmental fluctuations. The population dynamics is re...
Proof of the Feldman-Karlin conjecture on the maximum number of equilibria in an evolutionary system [0.03%]
傅伦曼-卡林猜想的证明：进化系统中平衡点的最大个数上限问题

Feldman and Karlin conjectured that the number of isolated fixed points for deterministic models of viability selection and recombination among n possible haplotypes has an upper bound of 2(n)-1. Here a proof is provided. The upper bound of...
Demographic stochasticity versus spatial variation in the competition between fast and slow dispersers [0.03%]
demographic stochasticity和空间变异下快速扩散者和慢速扩散者的竞争关系分析

Dispersal is an important strategy that allows organisms to locate and exploit favorable habitats. The question arises: given competition in a spatially heterogeneous landscape, what is the optimal rate of dispersal? Continuous population m...

We consider a three-variable forest pest model, proposed by Rinaldi & Muratori (1992) [Rinaldi, S., Muratori, S., 1992. Limit cycles in slow-fast forest-pest models. Theor. Popul. Biol. 41, 26-43]. The model allows relaxation oscillations w...
The mechanistic basis of discrete-time population models: the role of resource partitioning and spatial aggregation [0.03%]

The purpose of this paper is to present a unified view to understand mechanistic basis of various discrete-time population models from the viewpoints of resource partitioning and spatial aggregation of individuals. A first-principles deriva...
