Are mutagenic non D-loop direct repeat motifs in mitochondrial DNA under a negative selection pressure? [PDF]

open access: yes, 2017
Non D-loop direct repeats (DRs) in mitochondrial DNA (mtDNA) have been commonly implicated in the mutagenesis of mtDNA deletions associated with neuromuscular disease and ageing.

The complete mitochondrial genome of Aquila nipalensis and its phylogenetic position

open access: yesMitochondrial DNA. Part B. Resources, 2019
Mitochondrial genome sequences are valuable resources for systematics and conservation biology studies. In this paper, we present the complete mitogenome of Aquila nipalensis which was 18,450 bp in length.

Landscape genetics of Schistocephalus solidus parasites in threespine stickleback (Gasterosteus aculeatus) from Alaska. [PDF]

open access: yesPLoS ONE, 2015
The nature of gene flow in parasites with complex life cycles is poorly understood, particularly when intermediate and definitive hosts have contrasting movement potential.

Past Environmental Change and Seasonal Migration Shaped Pronounced Variability in the Phylogenomic History of a Morphologically Cryptic Bird Radiation

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Modelling demographic changes through time in combination with phylogenomic reconstructions provides a promising avenue to better understand the impact of past environmental changes on biogeographic patterns, yet we have only begun to exploit this potential.

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

open access: yesBMC 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]

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

Application of Invertebrate‐Derived DNA Barcoding (iDNA) in Blood Sucking Leeches From West Sumatra: A Discovery of Blue‐Eyed Litter Frog Leptobrachium waysapuntiense

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study explores the use of invertebrate‐derived DNA (iDNA) from haematophagous leeches to assess vertebrate biodiversity in the tropical rainforests of Indonesia. By applying Sanger sequencing with five primer sets, we detected 17 unique vertebrate taxa, including the rare Leptobrachium waysepuntiense, demonstrating the potential of iDNA as a ...

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.

Free Radicals in Health and Disease

open access: yesMedComm, Volume 6, Issue 10, October 2025.
Free radicals have dual roles that can either selectively create oxidative damages to transformed cells in treating proliferative diseases such as cancers and some dermatological disorders or boost the antioxidant system in treating degenerative diseases such as neurodegenerative disorder, joint degeneration, and metabolic conditions.

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

open access: yesDiversity, 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 ...
