Consanguineous unions increase the frequency at which identical genomic segments are inherited along separate paths of descent, decreasing coalescence times for pairs of alleles drawn from an individual who is the offspring of a consanguine...
Model of neo-Malthusian population anticipating future changes in resources [0.03%]
新的马尔萨斯人口模型预测未来资源的变化

In this paper we develop a class of models to study a population and resource dynamical system in which the decision to give birth is based on a rational far-sighted cost-benefit analysis on what the future of the resource level will be. Th...
Inference of gene flow in the process of speciation: Efficient maximum-likelihood implementation of a generalised isolation-with-migration model [0.03%]
谱系分化的基因流的统计推断：有效计算隔离分化模型中基因流的最大似然法估算值

The 'isolation with migration' (IM) model has been extensively used in the literature to detect gene flow during the process of speciation. In this model, an ancestral population split into two or more descendant populations which subsequen...
Variance and limiting distribution of coalescence times in a diploid model of a consanguineous population [0.03%]

Recent modeling studies interested in runs of homozygosity (ROH) and identity by descent (IBD) have sought to connect these properties of genomic sharing to pairwise coalescence times. Here, we examine a variety of features of pairwise coal...

While facultative sex is common in sexually reproducing species, for reasons of tractability most mathematical models assume that such sex is asynchronous in the population. In this paper, we develop a model of switching environments to ins...
Structure of the G-matrix in relation to phenotypic contributions to fitness [0.03%]

Classical theory in population genetics includes derivation of the stationary distribution of allele frequencies under balance between selection, genetic drift, and mutation. Here we investigate the simplest generalization of these single l...
Fitting stochastic predator-prey models using both population density and kill rate data [0.03%]
基于人口密度和杀伤率数据拟合随机捕食者-猎物模型

Frédéric Barraquand
Most mechanistic predator-prey modelling has involved either parameterization from process rate data or inverse modelling. Here, we take a median road: we aim at identifying the potential benefits of combining datasets, when both population...

How long a newly emerging trait will stay in a population is a fundamental but rarely asked question in cultural evolution. To tackle this question, the distribution and mean of the time to extinction of a discrete cultural trait are derive...

What the reproductive number R0 can and cannot tell us about COVID-19 dynamics [0.03%]
基本传染数R0能告诉我们关于新冠肺炎疫情的什么信息？

Clara L Shaw
The reproductive number R (or R0, the initial reproductive number in an immune-naïve population) has long been successfully used to predict the likelihood of pathogen invasion, to gauge the potential severity of an epidemic, and to set pol...
