Journal ArticleDOI
Tackling the population genetics of clonal and partially clonal organisms
TL;DR: The available methods for detecting recombination in organisms that are thought to reproduce strictly, or essentially asexually are discussed, focusing on those best suited when working with limited genetic information, such as a few genetic markers or DNA sequences.
Journal ArticleDOI
A continuum of genetic divergence from sympatric host races to species in the pea aphid complex
TL;DR: The pea aphid complex illustrates how ecological divergence can be sustained among many hybridizing populations and how insect host races blend into species by gradual reduction of gene flow.
Journal ArticleDOI
Phylogenetic relationships between parthenogens and their sexual relatives: the possible routes to parthenogenesis in animals
TL;DR: The possible evolutionary routes to parthenogenesis are reviewed based on a survey of the phylogenetic relationships between sexual and parthenogenetic lineages in a broad range of animals and the influences of these mechanisms on both the genetic properties and the ecological life styles of the resulting lineages are discussed.
Journal ArticleDOI
Symbiotic bacterium modifies aphid body color.

TL;DR: It is discovered that infection with a facultative endosymbiont of the genus Rickettsiella changes the insects’ body color from red to green in natural populations of the pea aphid.
Journal ArticleDOI
Ecology and evolution of sex in aphids.
TL;DR: Understanding of the genetic and evolutionary consequences of reproductive modes in aphids and their distributions in nature has greatly advanced, and they have provided tools that promise to make aphids important organisms with which to examine general advantages of sex.
