Genotyping of human lice suggests multiple emergencies of body lice from local head louse populations. [PDF]
PLoS Neglected Tropical Diseases, 2010 BACKGROUND: Genetic analyses of human lice have shown that the current taxonomic classification of head lice (Pediculus humanus capitis) and body lice (Pediculus humanus humanus) does not reflect their phylogenetic organization.

Evidence that head and body lice on homeless persons have the same genotype. [PDF]
PLoS ONE, 2012 Human head lice and body lice are morphologically and biologically similar but have distinct ecologies. They were shown to have almost the same basic genetic content (one gene is absent in head lice), but differentially express certain genes, presumably ...

Parasites & Vectors, 2018 Background Control of the sea louse Caligus rogercresseyi in the Chilean salmonid industry is reliant on chemical treatments. Azamethiphos was introduced in 2013, although other organophosphates were previously used.

Aquaculture Environment Interactions, 2020 Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million cleaner fish per year.

Molecular mechanisms of Eda‐mediated adaptation to freshwater in threespine stickleback
Molecular Ecology, EarlyView., 2023 Abstract A main goal of evolutionary biology is to understand the genetic basis of adaptive evolution. Although the genes that underlie some adaptive phenotypes are now known, the molecular pathways and regulatory mechanisms mediating the phenotypic effects of those genes often remain a black box.
