Time-dependent solutions of the spatially implicit neutral model of biodiversity [0.03%]

Previous research into the neutral theory of biodiversity has focused mainly on equilibrium solutions rather than time-dependent solutions. Understanding the time-dependent solutions is essential for applying neutral theory to ecosystems in...

Individual learning and social learning are two primary abilities supporting cultural evolution. Conditions for their evolution have mostly been studied by investigating gene frequency dynamics, which essentially implies constant population...
Mathematical properties of Fst between admixed populations and their parental source populations [0.03%]
关于admixture人群及其亲源人群的Fst的数学性质分析
Simina M Boca,Noah A Rosenberg
Simina M Boca
We consider the properties of the F(st) measure of genetic divergence between an admixed population and its parental source populations. Among all possible populations admixed among an arbitrary set of parental populations, we show that the...
A unifying framework for assessing changes in life expectancy associated with changes in mortality: the case of violent deaths [0.03%]
一个评估与死亡率变化相关的生命预期变化的统一框架：以暴力死亡为例

Hiram Beltrán-Sánchez
For over forty years, demographers have worked intensely to develop methods that assess a gain in life expectancy from a reduction in mortality, either hypothetical or observed. This considerable body of research was motivated by assessing ...
Admissible mixing distributions for a general class of mixture survival models with known asymptotics [0.03%]
一类具有已知渐近性质的混合生存模型的可接受混合分布

Trifon I Missov
Statistical analysis of data on the longest living humans leaves room for speculation whether the human force of mortality is actually leveling off. Based on this uncertainty, we study a mixture failure model, introduced by Finkelstein and ...
Genetic diversity of microsatellite loci in hierarchically structured populations [0.03%]
分层群体中的微卫星多态性遗传多样性研究
Seongho Song,Dipak K Dey,Kent E Holsinger
Seongho Song
Microsatellite loci are widely used for investigating patterns of genetic variation within and among populations. Those patterns are in turn determined by population sizes, migration rates, and mutation rates. We provide exact expressions f...
Estimation of parameters in large offspring number models and ratios of coalescence times [0.03%]
大繁殖数模型中的参数估计及合并时间比例估算
Bjarki Eldon
Bjarki Eldon
The ratio of singletons to the total number of segregating sites is used to estimate a reproduction parameter in a population model of large offspring numbers without having to jointly estimate the mutation rate. For neutral genetic variati...
A spatially explicit model of sex ratio evolution in response to sex-biased dispersal [0.03%]
一种关于性别偏移扩散的空间明确的性比率进化模型
Jean-Michel Guillon,Jean Bottein
Jean-Michel Guillon
Sex-biased dispersal occurs in all seed plants and many animal species. Theoretical models have shown that sex-biased dispersal can lead to evolutionarily stable biased sex ratios. Here, we use a spatially explicit chessboard model to simul...
The effect of recurrent mutation on the frequency spectrum of a segregating site and the age of an allele [0.03%]
反复突变对分离位点的频率光谱及等位基因年龄的影响
Paul A Jenkins,Yun S Song
Paul A Jenkins
The sample frequency spectrum of a segregating site is the probability distribution of a sample of alleles from a genetic locus, conditional on observing the sample to be polymorphic. This distribution is widely used in population genetic i...

Private microsatellite alleles tend to be found in the tails rather than in the interior of the allele size distribution. To explain this phenomenon, we have investigated the size distribution of private alleles in a coalescent model of two...
