Stochastic ecological and epidemiological models are now routinely used to inform management and decision making throughout conservation and public-health. A difficulty with the use of such models is the need to resort to simulation methods...
Mutating away from your enemies: the evolution of mutation rate in a host-parasite system [0.03%]
遗传变异助宿主对抗敌人：一种遗传寄生系统的变异率进化研究

The rate at which mutations occur in nature is itself under natural selection. While a general reduction of mutation rates is advantageous for species inhabiting constant environments, higher mutation rates can be advantageous for those inh...
A coalescent dual process in a Moran model with genic selection [0.03%]
Moran模型中适应性genic选择的凝聚过程的对偶过程

A coalescent dual process for a multi-type Moran model with genic selection is derived using a generator approach. This leads to an expansion of the transition functions in the Moran model and the Wright-Fisher diffusion process limit in te...
Sex-specific spatio-temporal variability in reproductive success promotes the evolution of sex-biased dispersal [0.03%]
生殖成功率的性别差异性时空变化有利于单性扩散的进化

Inbreeding depression, asymmetries in costs or benefits of dispersal, and the mating system have been identified as potential factors underlying the evolution of sex-biased dispersal. We use individual-based simulations to explore how the m...
The limitation of species range: a consequence of searching along resource gradients [0.03%]

Ecological modelers have long puzzled over the spatial distribution of species. The random walk or diffusive approach to dispersal has yielded important results for biology and mathematics, yet it has been inadequate in explaining all pheno...

We consider a model of frequency-dependent selection, which we refer to as the Wildcard Model. A variety of more specific models, representing quite diverse biological situations, are covered by the Wildcard Model as particular cases. Two v...

Complex traits often involve interactions between different genetic loci. This can lead to sign epistasis, whereby mutations that are individually deleterious or neutral combine to confer a fitness benefit. In order to acquire the beneficia...

Metapopulation theory has recently been stirred by the development of a metapopulation persistence criterion (R(m)) quantifying the "lifetime dispersal success" of a newly colonized deme in a sparsely occupied metapopulation. No rigorous pr...
The impact of parasitoid emergence time on host-parasitoid population dynamics [0.03%]

We investigate the effect of parasitoid phenology on host-parasitoid population cycles. Recent experimental research has shown that parasitized hosts can continue to interact with their unparasitized counterparts through competition. Parasi...
Estimating primate divergence times by using conditioned birth-and-death processes [0.03%]

The fossil record provides a lower bound on the primate divergence time of 54.8 million years ago, but does not provide an explicit estimate for the divergence time itself. We show how the pattern of diversification through the Cenozoic can...
