Mitochondrial heteroplasmy in an avian hybrid form (Passer italiae: Aves, Passeriformes) [PDF]

open access: yesMitochondrial DNA Part B: Resources, 2019
Mitochondrial heteroplasmy is the result from biparental transmission of mitochondrial DNA (mtDNA) to the offspring. In such rare cases, maternal and paternal mtDNA is present in the same individual.

Diversity, abundance, and host relationships of avian malaria and related haemosporidians in New Mexico pine forests [PDF]

open access: yesPeerJ, 2017
Avian malaria and related haemosporidian parasites (genera Haemoproteus, Plasmodium, and Leucocytozoon) affect bird demography, species range limits, and community structure, yet they remain unsurveyed in most bird communities and populations.

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

open access: yesPLoS 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

Bringing back the dead: Genetic data from avian carcasses

open access: yesWildlife Society Bulletin, 2017
Advances in laboratory methods and DNA sequencing technology have enabled genetic analyses of noninvasive samples, museum specimens, fossil material, and more recently, carcasses.

Pleistocene phylogeographic effects on avian populations and the speciation process [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1998
Pleistocene biogeographic events have traditionally been ascribed a major role in promoting speciations and in sculpting the present-day diversity and distributions of vertebrate taxa.

Genetic Divergence of an Avian Endemic on the Californian Channel Islands. [PDF]

open access: yesPLoS ONE, 2015
The Californian Channel Islands are near-shore islands with high levels of endemism, but extensive habitat loss has contributed to the decline or extinction of several endemic taxa. A key parameter for understanding patterns of endemism and demography in

Population structure of avian malaria parasites

open access: yesEcology and Evolution, 2019
The geographic distribution of genetic diversity in malaria parasite populations (Apicomplexa: Haemosporida) presumably influences local patterns of virulence and the evolution of host‐resistance, but little is known about population genetic structure in

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

open access: yesPLoS 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

Climate cycling did not affect haplotype distribution in an abundant Southern African avian habitat generalist species, the familiar chat (Oenanthe familiaris). [PDF]

open access: yesIntegr Zool
Avian species diversity in Southern Africa is remarkably high, yet the mechanisms responsible for that diversity are poorly understood. While this is particularly true with respect to species endemic to the subregion, it is unclear as to how more broadly

Strong mitochondrial DNA support for a Cretaceous origin of modern avian lineages

open access: yesBMC Biology, 2008
Background Determining an absolute timescale for avian evolutionary history has proven contentious. The two sources of information available, paleontological data and inference from extant molecular genetic sequences (colloquially, 'rocks' and 'clocks'),
