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

open access: yesJournal 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 ...

Phylogeography of the Black-tailed Godwit Limosa limosa : substructuring revealed by mtDNA control region sequences

open access: yes, 2009
Black-tailed (Limosa limosa) and Hudsonian Godwits (L. haemastica) are sometimes described as a superspecies. The Black-tailed Godwit is further split into three subspecies on the basis of morphological differences (L. l. limosa, L. l. islandica and L. l.

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

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

Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

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

Maternal zinc alleviates tert-butyl hydroperoxide-induced mitochondrial oxidative stress on embryonic development involving the activation of Nrf2/PGC-1α pathway

open access: yesJournal of Animal Science and Biotechnology, 2023
Background Mitochondrial dysfunction induced by excessive mitochondrial reactive oxygen species (ROS) damages embryonic development and leads to growth arrest.

Comparative Phylogeography of Southern African Bird Species Suggests an Ephemeral Speciation Model

open access: yesDiversity, 2021
Southern Africa is remarkably rich in avian species diversity; however, the evolutionary and biogeographic mechanisms responsible for that diversity are, in general, poorly understood, and this is particularly true with respect to the many species that ...
