Parasites comprise a significant percentage of the biodiversity of the planet and are useful systems to test evolutionary and ecological hypotheses. In this study, we analyze the effect of host species identity and the immediate local species assemblage within mixed species colonies of nesting seabirds on patterns of genetic clustering within two species of multihost ectoparasitic lice. We use three genetic markers (one mitochondrial, COI, and two nuclear, EF1-α and wingless) and maximum…

“More Than Meets the Eye”: Cryptic Diversity and Contrasting Patterns of Host-Specificity in Feather Mites Inhabiting Seabirds
TLDR
The diversity and evolution of feather mites infesting six sympatric seabird species from six genera, breeding in the Cape Verde archipelago are examined and ectosymbiont and host life-history traits that might generate these patterns are discussed, such as host dispersal and breeding behavior and/or mite spatial and trophic specialization.
Persistence of single species of symbionts across multiple closely-related host species
TLDR
It is shown that mite populations from different host species represent a single species, suggesting that each of these species is a multi-host species in which dispersal of mites among host species prevents species divergence.
Diversity, ecology and evolution of feather mites in seabirds
TLDR
The main goal of this thesis was to investigate the evolutionary and ecological factors driving the diversity and community structure of feather mites inhabiting seabirds of the north-eastern Atlantic Ocean and Mediterranean Sea and to quantify feather mite morphological and genetic diversity within different seabird species and populations.
Host-switching: how it starts
TLDR
The Galapagos archipelago provides an exceptional host-parasite system to investigate details of parasite spillover and its implications for host health and survivorship.
Colonization of Parasites and Vectors
TLDR
Examples of natural and anthropogenic colonization of the Galapagos Islands by parasites and vectors are explored, focusing on one or more case studies that best represent the diversity of colonization mechanisms that has shaped parasite distribution in the archipelago.
WiSPA: A new approach for dealing with widespread parasitism
TLDR
The newly proposed algorithm, which is called WiSPA (WideSpread Parasitism Analyser), is applied to the well studied coevolutionary system of Primates and Enterobius (pinworms), where existing methods have been unable to reconcile the widespread parasitism present without permitting additional divergence events.

Host Specialization Differentiates Cryptic Species of Feather-Feeding Lice
TLDR
The results suggest that selection in this cryptic species complex reflects selection across the whole genus, and that this selection, in part, contributes to the maintenance of host specialization.
Comparative Ectoparasite Loads of Five Seabird Species in the Galapagos Islands
TLDR
It is found that inter-island differences were the main predictors of prevalence and infestation intensity in ectoparasitic lice found on seabirds on the Galapagos Archipelago.
The population genetics of host specificity: genetic differentiation in dove lice (Insecta: Phthiraptera)
TLDR
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.
Biogeography explains cophylogenetic patterns in toucan chewing lice.
TLDR
Recon reconstructions of host and louse phylogenies indicate that they do not branch in parallel, and their cophylogenetic history shows little or no significant cospeciation, suggesting that for some louse lineages biogeography may be more important than host associations in structuring louse populations and species, particularly when host life history or parasite life history might promote frequent host switching events between syntopic host species.
Philopatry drives genetic differentiation in an island archipelago: comparative population genetics of Galapagos Nazca boobies (Sula granti) and great frigatebirds (Fregata minor)
TLDR
It is shown that Galapagos Nazca booby (Sula granti) populations are substantially differentiated, even within the small geographic scale of this archipelago, while great frigatebird populations do not show any genetic structure.
Co‐phylogeography and comparative population genetics of the threatened Galápagos hawk and three ectoparasite species: ecology shapes population histories within parasite communities
TLDR
Comparative microevolutionary studies of multiple parasites occurring on a single host species suggest that the ischnoceran louse may yield insight into the cryptic evolutionary history of its endangered host, potentially aiding in its conservation management.
Multiple cophylogenetic analyses reveal frequent cospeciation between pelecaniform birds and Pectinopygus lice.
TLDR
Perfect congruence between phylogenies is not found in this association, probably as a result of occasional host switching by the lice, thus emphasizing the need for improved cophylogenetic methodologies.
An annotated checklist of parasitic lice (Insecta: Phthiraptera) from the Galápagos Islands.
TLDR
A host-parasite list, and a list of hosts which breed in the Galápagos Islands but without lice recorded from them are included, and four lectotypes from the Kellogg Collection are formally designate.
Long-term isolation of a highly mobile seabird on the Galapagos
TLDR
Signs of extensive gene flow are found over most of the range of magnificent frigatebirds, even across the Isthmus of Panama, which is a major barrier to gene flow in other tropical seabirds.
Using parasites to infer host population history: a new rationale for parasite conservation
TLDR
The use of estimated genealogies and population genetic patterns of parasites to illuminate their hosts' evolutionary and demographic history is advocated and will result in the recognition of new host records, parasite species and cryptic lineages, which will help lift the veil of ignorance with respect to parasite biodiversity.
