Using Historic and Contemporary Genomes to Assess the Genetic Consequences of a Population Decline in an Endangered Tern Population. [PDF]

open access: yesEvol Appl
ABSTRACT Many migratory species have experienced severe population declines, but the genetic consequences of such declines are still rarely assessed. The last Central European population of gull‐billed terns (Gelochelidon nilotica) has declined from 500 breeding pairs in the 1940s to 52 in 2025, whereas Mediterranean populations of this migratory ...

VoronaGasyCodes: A Public Database of Mitochondrial Barcodes for Malagasy Birds. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Molecular tools are increasingly being used to survey the presence of biodiversity and their interactions within ecosystems. Indirect methods, like environmental DNA (eDNA) and invertebrate‐derived DNA (iDNA), are dependent on sequence databases with accurate and sufficient taxonomic representation. These methods are increasingly being used in

Use of Contaminated Habitat and Associated Selenium Uptake Mediate Haemosporidian Parasite Infections in Wild Passerine Birds. [PDF]

open access: yesEcol Evol
We conducted a community‐scale field study to evaluate whether trace element contaminants derived from coal combustion residuals and nuclear fission products alter the dynamics of haemosporidian blood parasites, dipteran vectors, and avian hosts in riparian and wetland habitats in South Carolina, USA.

Sequencing of the complete mitochondrial genome of the common raven Corvus corax (Aves: Corvidae) confirms mitogenome-wide deep lineages and a paraphyletic relationship with the Chihuahuan raven C. cryptoleucus. [PDF]

open access: yesPLoS ONE, 2017
Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages that are hypothesised to have undergone speciation reversal upon secondary contact. Furthermore, common ravens

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

open access: yes, 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.

Low variation in the polymorphic Clock gene poly-Q region despite population genetic structure across barn swallow (Hirundo rustica) populations. [PDF]

open access: yesPLoS ONE, 2011
Recent studies of several species have reported a latitudinal cline in the circadian clock gene, Clock, which influences rhythms in both physiology and behavior. Latitudinal variation in this gene may hence reflect local adaptation to seasonal variation.

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]

open access: yes, 2008
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using

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.

Phylogenetic analyses to uncover the evolutionary relationship of a newly sequenced mitochondrial genome from an Eastern spinebill (Acanthorhynchus tenuirostris)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The Eastern spinebill (Acanthorhynchus tenuirostris), a passerine bird in the family Meliphagidae (honeyeaters), a dominant group of birds in Australia and New Guinea. The aim of this study was to sequence the complete mitochondrial genome of the Eastern

Complete mitochondrial genome of white-backed woodpecker Dendrocopos leucotos (Piciformes: Picidae) and its phylogenetic position

open access: yesMitochondrial DNA. Part B. Resources, 2017
The white-backed woodpecker (Dendrocopos leucotos) is an ecologically important bird in Eurasian forest ecosystems. In this study, the complete mitochondrial genome of the species was sequenced using next-generation sequencing technology.
