Recently, several authors have proposed that the availability of intermediate hosts (IHs) for definitive hosts (DHs) may contribute to determining the dynamics and evolutionary ecology of parasites with facultative complex life cycles. The ...
A coalescent dual process in a Moran model with genic selection, and the lambda coalescent limit [0.03%]
Moran模型中的genic选择的对数过程及其λ凝聚极限

The genealogical structure of neutral populations in which reproductive success is highly-skewed has been the subject of many recent studies. Here we derive a coalescent dual process for a related class of continuous-time Moran models with ...
Species coexistence under resource competition with intraspecific and interspecific direct competition in a chemostat [0.03%]
化学统计中资源竞争下种间和种内直接竞争下的物种共存

Competition theory has developed separately for direct competition and for exploitative competition. However, the combined effects of the two types of competition on species coexistence remain unclear. To examine how intraspecific and inter...
Size-dependent sex change can be the ESS without any size advantage of reproduction when mortality is size-dependent [0.03%]
当死亡率依赖于体型时,即使没有繁殖的体型优势,基于体型的性别转变仍可以是进化稳定策略(ESS)

Almost all models of sex change evolution assume that reproductive rate increases with body size. However, size-dependent sex changing plants often show size-independent reproductive success, presumably due to pollen limitation. Can the obs...
Overdispersion in allelic counts and θ-correction in forensic genetics [0.03%]
法医遗传学中的等位基因计数过度离散化和θ校正

We present a statistical model for incorporating the extra variability in allelic counts due to subpopulation structures. In forensic genetics, this effect is modelled by the identical-by-descent parameter θ, which measures the relationshi...
Coalescent approximation for structured populations in a stationary random environment [0.03%]

We establish convergence to the Kingman coalescent for the genealogy of a geographically-or otherwise-structured version of the Wright-Fisher population model with fast migration. The new feature is that migration probabilities may change i...

Ocean currents, prevailing winds, and the hierarchical structures of river networks are known to create asymmetries in re-colonization between habitat patches. The impacts of such asymmetries on metapopulation persistence are seldom conside...
Alternatives to the Wright-Fisher model: the robustness of mitochondrial Eve dating [0.03%]
除Wright-Fisher模型之外的选择——母体线粒体Eve年代测定的稳健性分析

Methods of calculating the distributions of the time to coalescence depend on the underlying model of population demography. In particular, the models assuming deterministic evolution of population size may not be applicable to populations ...
The storage effect due to frequency-dependent predation in multispecies plant communities [0.03%]
基于捕食频率依赖的储存效应及其在多维植物群落中的作用

Peter Chesson
Frequency-dependent seed predation (FDP) has been shown to be a powerful coexistence mechanism in models of annual plant communities. However, FDP undermines the competition-based coexistence mechanism called the storage effect (SEc), which...

Populations that are structured into small local patches are a common feature of ecological and epidemiological systems. Models describing this structure are often referred to as metapopulation models in ecology or household models in epide...
