The usage of structured population models can make substantial contributions to public health, particularly for infections where clinical outcomes vary over age. There are three theoretical challenges in implementing such analyses: (i) deve...
Quantifying time-inhomogeneous stochastic introgression processes with hazard rates [0.03%]
用危险率量化非均匀随机渗入过程

Introgression is the permanent incorporation of genes from one population into another through hybridization and backcrossing. It is currently of particular concern as a possible mechanism for the spread of modified crop genes to wild popul...
The joint allele frequency spectrum of multiple populations: a coalescent theory approach [0.03%]
多重群体联合等位基因频率谱系的煤核理论方法
Hua Chen
Hua Chen
The allele frequency spectrum is a series of statistics that describe genetic polymorphism, and is commonly used for inferring population genetic parameters and detecting natural selection. Population genetic theory on the allele frequency ...

Estimation of the rate and effect of new beneficial mutations in asexual populations [0.03%]
无性群体中新有利突变率和效应的估计
Wei Zhang,Vasudha Sehgal,Duy M Dinh et al.
Wei Zhang et al.
The rate and effect of available beneficial mutations are key parameters in determining how a population adapts to a new environment. However, these parameters are poorly known, in large part because of the difficulty of designing and inter...

Global asymptotic stability of density dependent integral population projection models [0.03%]
密度依赖型积分人口投影模型的全局渐近稳定性

Many stage-structured density dependent populations with a continuum of stages can be naturally modeled using nonlinear integral projection models. In this paper, we study a trichotomy of global stability result for a class of density depen...

Many scenarios in the living world, where individual organisms compete for winning positions (or resources), have properties of auctions. Here we study the evolution of bids in biological auctions. For each auction, n individuals are drawn ...
The mapping of epistatic effects onto a genealogical tree in haploid populations [0.03%]
单倍体种群中的基因效应映射到家谱树上
Cortland K Griswold,Danielle J Eisner
Cortland K Griswold
In this paper we present a model that maps epistatic effects onto a genealogical tree for a haploid population. Prior work has demonstrated that genealogical structure causes the genotypic values of individuals to covary. Our results indica...

Many long-lived plants such as trees show masting or intermittent and synchronized reproduction. In a coupled chaos system describing the dynamics of individual-plant resource budgets, masting occurs when the resource depletion coefficient ...
Top-down control in a patchy environment: revisiting the stabilizing role of food-dependent predator dispersal [0.03%]
顶端控制在斑块生境中的作用：重新审视食饵依赖性捕食者扩散的稳定作用

In this paper, we revisit the stabilizing role that predator dispersal and aggregation have in the top-down regulation of predator-prey systems in a heterogeneous environment. We consider an environment consisting of sites interconnected by...
Effects of demographic structure on key properties of stochastic density-independent population dynamics [0.03%]
人口结构对随机密度非依赖种群动态关键性质的影响

Yngvild Vindenes
The development of stochastic demography has largely been based on age structured populations, although other types of demographic structure, especially permanent and dynamic heterogeneity, are likely common in natural populations. The comb...
