The chewing lice: world checklist and biological overview.
Genetic Analysis of Lice Supports Direct Contact between Modern and Archaic Humans
It is shown that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years). Expand

Examining the genetic structure in the mitochondrial cytochrome oxidase I (COI) gene of two genera of lice occurring on multiple sympatric species of doves in southern North and Central America found that species of Physconelloides exhibited more genetic structure than did species of Columbicola.

The biology, ecology, and evolution of chewing lice
Comparative ecology of Neotropical bird lice (Insecta: Phthiraptera)
The bulk of variation in louse load was among host species nested within genera, although some variation occurred at higher taxonomic levels. Expand
How Birds Combat Ectoparasites
The evidence - or lack thereof - for many of the purported mechanisms birds have for dealing with ectoparasites are reviewed, focusing on features of the plumage and its components, as well as anti-parasite behaviors. Expand

This article reviews the research, relevant criticisms and unanswered questions pertaining to the influence of parasites on sexual selection. Expand
When do parasites fail to speciate in response to host speciation?
This work reconstructed trees from mitochondrial and nuclear DNA sequences for pigeons and doves and their feather lice and identified three apparent cases where the host has speciated but the associated parasite has not. Expand
Nuclear and mitochondrial genes contain similar phylogenetic signal for pigeons and doves (Aves: Columbiformes).
The validity of this assumption in the pigeons and doves is tested by comparing phylogenies derived from nuclear (beta-fibrinogen intron 7) and mitochondrial (cytochrome b) genes, which revealed no significant incongruence between trees derived from the two genes. Expand
Ecology of congruence: past meets present.
Careful comparison of chewing lice genera suggests that dispersal is a more fundamental barrier to host switching among related hosts than is establishment, and there is a correspondence between important ecological factors and the degree of phylogenetic congruence. Expand
