Host specialization differentiates cryptic species of feather-feeding lice.

31 Jan 2009 Parasite species with differentiated host-specific populations provide a natural opportunity to explore factors involved in parasite diversification. Columbicola macrourae is a species of ectoparasitic feather louse currently recognized from 15 ... Read more...

A novel test for host-symbiont codivergence indicates ancient origin of fungal endophytes in grasses.

30 May 2008 Significant phylogenetic codivergence between plant or animal hosts (H) and their symbionts or parasites (P) indicates the importance of their interactions on evolutionary time scales. However, valid and realistic methods to test for codivergence ... Read more...

What's in a name: the taxonomic status of human head and body lice.

14 Mar 2008 Human head lice (Anoplura: Pediculidae: Pediculus) are pandemic, parasitizing countless school children worldwide due to the evolution of insecticide resistance, and human body (clothing) lice are responsible for the deaths of millions as a result ... Read more...
