Selection on nuclear (or organelle) sites inevitably affects the spatial distribution of a neutral organelle (or nuclear) allele via transient cytonuclear disequilibrium. Here I examine this effect in terms of F(st) for a neutral allele by ...
The impact of network clustering and assortativity on epidemic behaviour [0.03%]
网络聚类和同配性对流行病学行为的影响分析

Jennifer Badham
Epidemic models have successfully included many aspects of the complex contact structure apparent in real-world populations. However, it is difficult to accommodate variations in the number of contacts, clustering coefficient and assortativ...
Interacting coexistence mechanisms in annual plant communities: Frequency-dependent predation and the storage effect [0.03%]
一年生植物群落中共存机制的相互作用:频率依赖性捕食和贮存效应

We study frequency-dependent seed predation (FDP) in a model of competing annual plant species in a variable environment. The combination of a variable environment and competition leads to the storage-effect coexistence mechanism (SE), whic...

Many predators are able to become better at spotting cryptic prey by recognising specific clues, but by concentrating on one prey type they will become worse at spotting other prey types. This phenomenon is known as the formation of a searc...
Evolution of resistance and progression to disease during clonal expansion of cancer [0.03%]
癌症克隆扩张过程中的耐药性进化及疾病进展
Richard Durrett,Stephen Moseley
Richard Durrett
Inspired by previous work of Iwasa et al. (2006) and Haeno et al. (2007), we consider an exponentially growing population of cancerous cells that will evolve resistance to treatment after one mutation or display a disease phenotype after tw...
The risk of competitive exclusion during evolutionary branching: effects of resource variability, correlation and autocorrelation [0.03%]
资源变异、相关性和自相关对进化分支中竞争排斥风险的影响

Jacob Johansson
Evolutionary branching has been suggested as a mechanism to explain ecological speciation processes. Recent studies indicate however that demographic stochasticity and environmental fluctuations may prevent branching through stochastic comp...
Spatially explicit neutral models for population genetics and community ecology: Extensions of the Neyman-Scott clustering process [0.03%]
用于群体遗传学和群落生态学的空间显式中立模型:奈曼-斯科特聚类过程的扩展

Spatially explicit models relating to plant populations have developed little since Felsenstein (1975) pointed out that if limited seed dispersal causes clustering of individuals, such models cannot reach an equilibrium. This paper aims to ...

We derive an expression for the variation between parallel trajectories in phenotypic evolution, extending the well known result that predicts the mean evolutionary path in adaptive dynamics or quantitative genetics. We show how this expres...

We study the evolutionary dynamics of a haploid population of infinite size recombining with a probability r in a two locus model. Starting from a low fitness locus, the population is evolved under mutation, selection and recombination unti...
Change and maintenance of variation in quantitative traits in the context of the Price equation [0.03%]
普赖斯方程视角下数量性状变异的产生与维持
Xu-Sheng Zhang,William G Hill
Xu-Sheng Zhang
The Price equation is a general description of evolutionary change in any character from one generation to the next due to natural selection and other forces such as mutation and recombination. Recently it has been widely utilised in many f...
