The development of statistical tests of natural selection at the DNA level in population
samples has been ongoing for the past 13 years. The current state of the field is reviewed …

This paper reviews how statistical tests of neutrality have been used to address questions in
molecular ecology are reviewed. The work consists of four major parts: a brief review of the …

Positive selection can be inferred from its effect on linked neutral variation. In the restrictive
case when there is no recombination, all linked variation is removed. If recombination is …

Theoretically, divergent selection on sensory systems can cause speciation through sensory
drive. However, empirical evidence is rare and incomplete. Here we demonstrate sensory …

DnaSP is a Windows integrated software package for the analysis of the DNA polymorphism
from nucleotide sequence data. DnaSP version 3 incorporates several methods for …

The co-evolutionary 'arms race'is a widely accepted model for the evolution of host–
pathogen interactions. This model predicts that variation for disease resistance will be …

FRIGIDA (FRI) is a major gene involved in the regulation of flowering time in Arabidopsis
thaliana. Nucleotide variation at this gene was investigated by sequencing 25 field ecotypes …

Divergent natural selection acting on ecological traits, which also affect mate choice, is a key
element of ecological speciation theory, but has not previously been demonstrated at the …

Pathogen resistance is an ecologically important phenotype increasingly well understood at
the molecular genetic level. In this article, we examine levels of avrRpt2-dependent …

The fitness effects of classes of DNA mutations can be inferred from patterns of nucleotide
variation. A number of studies have attributed differences in levels of polymorphism and …
