Genotyping of human lice suggests multiple emergencies of body lice from local head louse populations. [PDF]
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.

Prediction of the salmon lice infestation pressure in a Norwegian fjord
A further growth in the Norwegian aquaculture industry might potentially be hampered by the conclusion that it is not environmentally sustainable. As direct measurements of the lice induced mortality on wild salmonids are impossible, the management is ...

Impacts of salmon lice on mortality, marine migration distance and premature return in sea trout
Brown trout Salmo trutta (L.) is a facultative anadromous species, where a portion of individuals in populations with access to the sea perform migrations to use the richer feeding resources.
