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 ...

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.

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

Genetic Relationship Analysis of <i>Pastor roseus</i> Based on <i>COI</i> and <i>Cytb</i> Gene Sequences. [PDF]

open access: yesEcol Evol
Pastor roseus exhibits exceptionally high mitochondrial diversity (haplotype diversity Hd > 0.94). The AT‐rich nucleotide composition in its COI and Cytb genes enhances energy metabolism efficiency during flight, while high haplotype diversity contributes to population resilience against environmental fluctuations.

SwarmGenomics: A Unified Pipeline for Individual-Based Whole-Genome Analyses. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Advances in sequencing technologies have made whole‐genome data widely accessible, enabling research in population genetics, evolutionary biology, and conservation. However, analysing whole‐genome sequencing (WGS) data remains challenging, often requiring multiple specialised tools and substantial bioinformatics expertise.

Ancient origin and maternal inheritance of blue cuckoo eggs [PDF]

open access: yes, 2016
Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or 'gentes') in avian brood parasites.

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

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

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.
