The egalitarian allotment of gametes to each allele at a locus (Mendel's law of segregation) is a near-universal phenomenon characterizing inheritance in sexual populations. As exceptions to Mendel's law are known to occur, one can investig...
Joint effect of changing selection and demography on the site frequency spectrum [0.03%]
变化选择与人口数量对位点频率谱联合影响的作用

The site frequency spectrum (SFS) is an important statistic that summarizes the molecular variation in a population, and is used to estimate population-genetic parameters and detect natural selection. Here, we study the SFS in a randomly ma...

Game theory has emerged as an important tool to understand interacting populations in the last 50 years. Game theory has been applied to study population dynamics with optimal behavior in simple ecosystem models, but existing methods are ge...
Success-biased social learning in a one-consumer, two-resource model [0.03%]
成功偏见的社会学习在一个消费者和两种资源的模型中

Previous analyses have predicted that social learning should not evolve in a predator-prey system. Here we examine whether success-biased social learning, by which social learners copy successful demonstrators, allows social learning by for...
Rate of coalescence of lineage pairs in the Spatial Λ-Fleming-Viot process [0.03%]

We revisit the Spatial Λ-Fleming-Viot process introduced in Barton and Kelleher (2010). Particularly, we are interested in the time T0 to the most recent common ancestor for two lineages. We distinguish between the cases where the process ...

For the two-patch logistic model, we study the effect of dispersal intensity and dispersal asymmetry on the total population abundance and its distribution. Two complete classifications of the model parameter space are given: one concerning...
Selection on age-specific survival: Constant versus fluctuating environment [0.03%]
固定与波动环境下的年龄特异性生存选择

According to a classic result in evolutionary biodemography, selection on age-specific survival invariably declines with reproductive age. The result assumes proportional changes in survival and a constant environment. Here, we look at sele...

When we examine the life history of humans against our closest primate relatives, the other great apes, there is notably a greater longevity in humans which includes a distinctive postmenopausal life stage, leading to the question, "How did...
Variances and covariances of linear summary statistics of segregating sites [0.03%]

Each mutation in a population sample of DNA sequences can be classified by the number of sequences that inherit the mutant nucleotide, the resulting frequencies are known as mutations of different sizes or site frequency spectrum. Many summ...
Evolution of trustfulness in the case where resources for cooperation are sometimes absent [0.03%]
合作资源偶尔缺乏情况下的信任演化
Shun Kurokawa
Shun Kurokawa
It is worth investigating the existence of cooperation, which is costly for the actor but beneficial to the recipient (precisely because it is costly for the former). If players, when they approach defectors, stop their relationship with th...
