We study the influence of nonlocal intraspecies prey competition on the spatiotemporal patterns arising behind predator invasions in two oscillatory reaction-diffusion integro-differential models. We use three common types of integral kerne...

In spatially distributed populations, global panmixia can be regarded as the limiting case of long-distance migration. The effect of incorporating partial panmixia into single-locus clines maintained by migration and selection is investigat...
The SIS and SIR stochastic epidemic models: a maximum entropy approach [0.03%]
SIS和SIR随机流行病模型：一种最大熵方法

J R Artalejo
We analyze the dynamics of infectious disease spread by formulating the maximum entropy (ME) solutions of the susceptible-infected-susceptible (SIS) and the susceptible-infected-removed (SIR) stochastic models. Several scenarios providing h...
Time to the MRCA of a sample in a Wright-Fisher model with variable population size [0.03%]

Determining the expected distribution of the time to the most recent common ancestor of a sample of individuals may deliver important information about the genetic markers and evolution of the population. In this paper, we introduce a new r...
On the extended Moran model and its relation to coalescents with multiple collisions [0.03%]
扩展的Moran模型及其与多碰撞煤堆模型的关系

Thierry Huillet
We study the asymptotics of the extended Moran model as the total population size N tends to infinity. Two convergence results are provided, the first result leading to discrete-time limiting coalescent processes and the second result leadi...
Sexual conflict in viscous populations: the effect of the timing of dispersal [0.03%]
黏性种群中的性别冲突：扩散时机的影响
Geoff Wild,Tommaso Pizzari,Stuart A West
Geoff Wild
In recent years, there has been increasing theoretical and empirical examination of how sexual conflict can arise between males and females. However, much this work has implicitly assumed that interactions take place in panmictic population...
Recombination and the evolution of coordinated phenotypic expression in a frequency-dependent game [0.03%]
重组与频率依赖性博弈中表型表达协调进化中的作用

Michal Arbilly et al.
A long standing question in evolutionary biology concerns the maintenance of adaptive combinations of traits in the presence of recombination. This problem may be solved if positive epistasis selects for reducing the rate of recombination b...

Following cell entry, viruses can be detected by cytotoxic T lymphocytes. These cytotoxic T lymphocytes can induce host cell apoptosis and prevent the propagation of the virus. Viruses with fewer epitopes have a higher survival probability,...
The consequences of rare sexual reproduction by means of selfing in an otherwise clonally reproducing species [0.03%]
偶尔进行自交的克隆繁殖物种的稀有性行为的后果
Joanna Masel,David N Lyttle
Joanna Masel
Clonal reproduction of diploids leads to an increase in heterozygosity over time. A single round of selfing will then create new homozygotic genotypes. Given the same allele frequencies, heritable genetic variation is larger when there are ...

We consider a survival game of gregarious individuals, in which the aim of the players is survival to reproductive age under predator attacks. The survivor's dilemma (shortly: SVD) game consists in the following: a group member either surel...
