We examine the characteristics of non-equilibrium dynamics produced by a simple well-known model of frequency-dependent selection at a single diploid locus. An examination of the parameter space of this "pairwise-interaction model" (PIM) re...

With technological advances in genetic mapping studies more of the genes and polymorphisms that underlie Quantitative Trait Loci (QTL) are now being identified. As the identities of these genes become known there is a growing need for an an...

Many applications of diversity indices are only valid if they are first transformed into their equivalent number of species. These equivalent numbers of species can be multiplicatively partitioned into independent alpha, beta and gamma comp...

A simple and efficient algorithm is presented for finding a maximum likelihood pedigree using microsatellite (STR) genotype information on a complete sample of related individuals. The computational complexity of the algorithm is at worst (...
From discrete to continuous evolution models: A unifying approach to drift-diffusion and replicator dynamics [0.03%]

We study the large population limit of the Moran process, under the assumption of weak-selection, and for different scalings. Depending on the particular choice of scalings, we obtain a continuous model that may highlight the genetic-drift ...
Investigating the role of enemies in temporal dynamics: Differential sensitivity, competition and stable coexistence [0.03%]

The impact of herbivores and other pests on plants varies greatly from year to year. Here we develop an analytical model of a temporal niche dynamic as a tool to examine how natural fluctuations in pest (enemy) levels may determine coexiste...
A predator-prey refuge system: Evolutionary stability in ecological systems [0.03%]
捕食者与猎物的避难所系统：生态系统进化稳定性

A refuge model is developed for a single predator species and either one or two prey species where no predators are present in the prey refuge. An individual's fitness depends on its strategy choice or ecotype (predators decide which prey s...

Plankton population dynamics in the upper layer of the ocean depends on upwelling processes that bring nutrients from deeper waters. In turn, these depend on the structure of the vertical velocity field. In coastal areas and in oceanic regi...

Viruses contained in live-attenuated virus vaccines (LAVV) can be transmitted between individuals, resulting in secondary or contact vaccinations. This fact has been exploited successfully in the use of the Oral Polio Vaccine (OPV) to bette...
On the accuracy of a diffusion approximation to a discrete state-space Markovian model of a population [0.03%]

The traditional Kolmogorov equations treat the size of a population as a discrete random variable. A model is introduced that extends these equations to incorporate environmental variability. Difficulties with this discrete model motivate a...
