A class of models of selectively neutral alleles
(Elsevier, 1980-10)
Using exchangeability as a statistical analog of neutrality, we derive a generalized sampling distribution for neutral alleles. The distribution depends upon a parameter that determines the underlying marginal distribution ...
A model of weak selection in the infinite alleles framework
(Springer-Verlag, 1986-08)
Ewens (1972) proposed a model in the infinite allele framework for populations with neutrality of all alleles at a particular locus. This paper proposes a generalisation of Ewens' result for situations where there is a ...
Evolution in fine-grained environments I. Environmental runs and the evolution of homeostasis
(Elsevier, 1978-06)
In this paper we discuss the problem of evolution when individual organisms are subjected to heterogeneous environments within their own lifetimes. We first develop a model of environmental heterogeneity in which there are ...
Evolution in fine-grained environments. II. Habitat selection as a homeostatic mechanism
(Elsevier, 1981-06)
A model of genotype specific habitat selection is developed for an organism subject to within-lifetime environmental fluctuations. Habitat selection is first overlaid upon both hard and soft selection Levene models with ...
The age structure of populations of Saccharomyces cerevisiae
(Elsevier, 1981-04)
A discrete deterministic model is described for the growth of an age-structured population of yeast, Saccharomyces cerevisiae, incorporating recent information on the asymmetry of cell division and control of the cell cycle ...
Stochastic models for cell motion and taxis
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2004-01)
Certain biological experiments investigating cell motion result in time lapse video microscopy data which may be modeled using stochastic differential equations. These models suggest statistics for quantifying experimental ...
The population genetics of parthenogenetic strains of Drosophila mercatorum
(Springer-Verlag, 1973-01)
A one locus model has been developed to describe parthenogenetic populations restoring diploidy by central fusion, terminal fusion and gamete duplication. It was found that in the absence of selection all populations become ...
