Simple Summary New sequencing technologies have now made it possible to sequence
entire genomes for a diversity of life on earth. Parasites comprise nearly half of all species …

Parasite diversification is influenced by many of the same factors that affect speciation of free-
living organisms, such as biogeographic barriers. However, the ecology and evolution of the …

The mitochondrial genomes (mitogenomes) of bilaterian animals are highly conserved
structures that usually consist of a single circular chromosome. However, several species of …

Many phoretic relationships between arthropods are understudied because of taxonomic
impediments. We here illustrate for avian lice riding on hippoboscid flies how new natural …

Despite their extensive diversity and ecological importance, the history of diversification for
most groups of parasitic organisms remains relatively understudied. Elucidating broad …

The pigeon louse Columbicola columbae is a longstanding and important model for studies
of ectoparasitism and host-parasite coevolution. However, a deeper understanding of its …

In parasites that strongly rely on a host for dispersal, geographic barriers that act on the host
will simultaneously influence parasite distribution as well. If their association persists over …

Psocodea (booklice and parasitic lice) is an order of insects containing species with
extensive mitochondrial genome rearrangements, particularly within the suborder …

Introduction Avian head lice comprise a diverse group of distantly related genera of lice that
exhibit a strongly convergent morphology. Due to their lack of free-living stages, their strong …
