Evolution of Recombination Due to Random Drift by Barton, N. H, Otto, Sarah P

“…In finite populations subject to selection, genetic drift generates negative linkage disequilibrium, on average, even if selection acts independently (i.e.,…”

Why Sex and Recombination? by Barton, N. H., Charlesworth, B.

“…Most higher organisms reproduce sexually, despite the automatic reproductive advantage experienced by asexual variants. This implies the operation of selective…”

Evolution of a Species' Range by Kirkpatrick, Mark, Barton, N. H.

“…Gene flow from the center of a species' range can stymie adaptation at the periphery and prevent the range from expanding outward. We study this process using…”

EFFECTS OF GENETIC DRIFT ON VARIANCE COMPONENTS UNDER A GENERAL MODEL OF EPISTASIS by Barton, N. H, Turelli, Michael

“…We analyze the changes in the mean and variance components of a quantitative trait caused by changes in allele frequencies, concentrating on the effects of…”

WILL POPULATION BOTTLENECKS AND MULTILOCUS EPISTASIS INCREASE ADDITIVE GENETIC VARIANCE? by Turelli, Michael, Barton, N. H

“…We apply new analytical methods to understand the consequences of population bottlenecks for expected additive genetic variance. We analyze essentially all…”

The Strength of Indirect Selection on Female Mating Preferences by Kirkpatrick, M., Barton, N. H.

“…An important but controversial class of hypotheses concerning the evolution of female preferences for extreme male mating displays involves ``indirect…”

Linkage and the Limits to Natural Selection by Barton, N. H

“…The probability of fixation of a favorable mutation is reduced if selection at other loci causes inherited variation in fitness. A general method for…”

Statistical Mechanics and the Evolution of Polygenic Quantitative Traits by Barton, N. H, de Vladar, H. P

“…The evolution of quantitative characters depends on the frequencies of the alleles involved, yet these frequencies cannot usually be measured. Previous groups…”

Theory and speciation by Turelli, Michael, Barton, Nicholas H., Coyne, Jerry A.

“…The study of speciation has become one of the most active areas of evolutionary biology, and substantial progress has been made in documenting and…”

The Effective Size of a Subdivided Population by Whitlock, M. C, Barton, N. H

“…This paper derives the long-term effective size, Ne, for a general model of population subdivision, allowing for differential deme fitness, variable emigration…”

How does epistasis influence the response to selection? by Barton, N H

“…Much of quantitative genetics is based on the 'infinitesimal model', under which selection has a negligible effect on the genetic variance. This is typically…”

A Model for the Evolution of Assortative Mating by de Cara, M. A. R., Barton, N. H., Kirkpatrick, M.

“…Many animals and plants show a correlation between the traits of the individuals in the mating pair, implying assortative mating. Given the ubiquity of…”

Spatial Waves of Advance with Bistable Dynamics: Cytoplasmic and Genetic Analogues of Allee Effects by Barton, N. H., Turelli, Michael

“…Unlike unconditionally advantageous “Fisherian” variants that tend to spread throughout a species range once introduced anywhere, “bistable” variants, such as…”

The infinitesimal model: Definition, derivation, and implications by Barton, N.H., Etheridge, A.M., Véber, A.

“…Our focus here is on the infinitesimal model. In this model, one or several quantitative traits are described as the sum of a genetic and a non-genetic…”

Genetic linkage and natural selection by Barton, N. H.

The Evolution of Recombination: Removing the Limits to Natural Selection by Otto, S. P, Barton, N. H
