Integrating coalescent species delimitation with analysis of host specificity reveals extensive cryptic diversity despite minimal mitochondrial divergence in the malaria parasite genus Leucocytozoon

BMC Evolutionary Biology, 2018
Background Coalescent methods that use multi-locus sequence data are powerful tools for identifying putatively reproductively isolated lineages, though this approach has rarely been used for the study of microbial groups that are likely to harbor many ...

Bloodmeal analysis reveals avian Plasmodium infections and broad host preferences of Culicoides (Diptera: Ceratopogonidae) vectors. [PDF]

PLoS ONE, 2012
Changing environmental conditions and human encroachment on natural habitats bring human populations closer to novel sources of parasites, which might then develop into new emerging diseases. Diseases transmitted by host generalist vectors are of special

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Full mitochondrial genome sequences of two endemic Philippine hornbill species (Aves: Bucerotidae) provide evidence for pervasive mitochondrial DNA recombination

BMC Genomics, 2011
Background Although nowaday it is broadly accepted that mitochondrial DNA (mtDNA) may undergo recombination, the frequency of such recombination remains controversial.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

A Brief Review of Non-Avian Reptile Environmental DNA (eDNA), with a Case Study of Painted Turtle (Chrysemys picta) eDNA Under Field Conditions

Diversity, 2019
Environmental DNA (eDNA) is an increasingly used non-invasive molecular tool for detecting species presence and monitoring populations. In this article, we review the current state of non-avian reptile eDNA work in aquatic systems, and present a field ...

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Molecular detection and genetic diversity of avian haemosporidian parasites in Iran. [PDF]

PLoS ONE, 2018
BACKGROUND:The mobility of birds across or between continents exposes them to numerous vectors that have the potential to transmit pathogens and spread them into new regions. A combination of rich species diversity of birds along with the small amount of

Ancient Plumage Colour Genetics Reveal Goose Domestication and Hybridization

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT In archaeological assemblages, differentiating the European domestic goose and its wild progenitor, the greylag goose (Anser anser), has been challenging due to their similar skeletal morphologies. A short region of mitochondrial DNA (mtDNA) analysed from ancient DNA (aDNA) has been shown to distinguish wild greylags from domestic geese, but ...
