The tribes Pteromyini (flying squirrels) and Sciurini (tree squirrels), two closely related taxa within the family Sciuridae, exhibit distinct locomotion modes, energy requirements, and likely face different selective pressures on mitochondrial protein-coding genes (PCGs). We analysed 13 mitochondrial genome sequences from species belonging to the tribe Pteromyini and 117 from species belonging to the tribe Sciurini. Phylogenetic analysis revealed Pteromyini and Sciurini formed a sister relationship within the family Sciuridae. Among the 13 PCGs, ATP8 exhibited the highest dN/dS values, while COX1 showed the lowest. The background selection ratio (ω2) values for six genes (ND1, ND2, ND4, ATP6, ND5, and COX3) in Pteromyini were lower than the foreground selection ratio (ω0) values observed in Sciurini. A RELAX analysis revealed that CYTB, ND4, ATP6, and COX3 genes experienced intensified in selection strength. BUSTED analysis identified stronger signatures of diversifying selection in CYTB and ATP6, highlighting amino acid changes. MEME identified episodic diversifying selection at specific sites among eight PCGs. These findings revealed distinct selective pressures on PCGs in flying and tree squirrels.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.

To date, seven different gene orders (A-G) have been described, yet comprehensive investigations of the actual number of arrangements, as well as comparative analyses and evolutionary reconstructions of mitochondrial genome evolution within the whole class Octocorallia, have been often overlooked. Here, we considered the complete mitochondrial genomes available for octocorals and explored their structure and gene order variability. Our results updated the actual number of mitochondrial gene order arrangements so far known for octocorals from 7 to 14 and allowed us to explore and preliminarily discuss the role of some of the structural and functional factors in the mitogenomes. We performed comparative mitogenomic analyses on the existing and novel octocoral gene orders, considering different mitogenomic structural features such as genome size, GC percentage, AT and GC skewness. The mitochondrial gene order history mapped on a recently published nuclear loci phylogeny showed that the most common rearrangement events in octocorals are inversions, inverted transpositions and transpositions. Furthermore, gene order rearrangement events were restricted only to some regions of the tree. Overall, different rearrangement events arose independently and from the ancestral and most common gene order, instead of being derived from other rearranged orders. Finally, our data demonstrate how the study of mitochondrial gene orders can be used to explore the evolution of octocorals and in some cases can be used to assess the phylogenetic placement of certain taxa.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.

Bayesian and Maximum Likelihood phylogenetic analyses were carried out using a fragment of the mitochondrial COI gene. Putative cryptic species were explored using the 'barcode gap' approach in the software ASAP. A genetic landscape shape analysis was carried out using the program Alleles in Space. The analyses revealed highly divergent and well-supported clades of L. italica dispersed across Tunisia (Clades A1 and A2), Greece (Clade B) and Italy (Clades C1 and C2). High genetic dissimilarity among clades suggested that L. italica constitute a cryptic species complex. Divergence among different L. italica lineages (Clades A, B and C) occurred around 7-4.5 Ma. The detected high genetic distances among clades did not result from atypical mitochondrial DNAs or intracellular infection by Wolbachia bacteria. The complex history of the Mediterranean Sea appears to have played a significant role in shaping the phylogeographic pattern of Ligia italica. Additional morphological and molecular studies are needed to confirm the existence of cryptic species in Ligia italica in Mediterranean.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.

The CR sequences of 455 mackerel samples collected from 23 localities at four fishing grounds revealed 333 haplotypes with haplotype diversity (h) per population, ranging between 0.8933 and 1.000, with an average of 0.9781.

Two clades were separated by 26 mutational steps. Each clade formed star-like clusters with many haplotypes derived from a common haplotype. Moreover, an analysis of molecular variance (AMOVA) revealed no significant differences among the studied localities, suggesting the presence of a single population in the GoT. Pairwise differences between samples from different fishing regions also indicated no population structure. Both Tajima's D and Fu's FS statistics were highly significant for the two clades but nonsignificant for the entire population according to a mismatch distribution analysis. These results confirmed that both clades experienced demographic expansion.

This study analyzed mitochondrial DNA (mtDNA) sequences of 73 bottlenose dolphin samples collected between 1999 and 2016 along the Turkish Black Sea coast, Turkish Straits System (TSS), Aegean, and Mediterranean Seas revealing 14 haplotypes, eight of which are reported here for the first time.The haplotype network shows two main nodes with star-like sub-networks, but no apparent geographic pattern. The lack of geographical groupings of haplotypes indicates the high mobility of the species within the sampled area. The northern Black Sea bottlenose dolphins (NBS) appear to be genetically differentiated from those in the southwestern Black Sea (SBS), Mediterranean, and Atlantic Ocean, but not from the TSS and Aegean Sea populations. Besides, SBS bottlenose dolphins were differentiated only from those in the western Mediterranean (WM) and the Atlantic. Therefore, NBS and SBS bottlenose dolphins should at least be categorized as different populations. However, contrary to some previous studies there was no evidence supporting the classification of Black Sea bottlenose dolphins as a separate subspecies.The TSS differs only from the Atlantic and the Aegean, and functions like a migratory 'melting pot' for surrounding populations. Despite the largest sample size, NBS bottlenose dolphins exhibited the lowest haplotype and nucleotide diversity. This low genetic diversity and potential isolation from adjacent populations highlight the need for prioritizing the conservation of NBS bottlenose dolphins.","PeriodicalId":74204,"journal":{"name":"Mitochondrial DNA.

The monophyly of Symphyta was not supported. The Xyeloidea was the earliest branching clade in the Hymenoptera. The Orussoidea was closely related to Apocrita. Within Apocrita, the Parasitoida was non-monophyletic. The monophyly of most Parasitoida superfamilies received strong support. The Proctotrupomorpha clade was supported in Bayesian's analysis. The Apoidea was monophyletic when excluding Ampulex compressa from consideration. The superfamilies Vespoidea and Chrysidoidea were found to be non-monophyletic. Comparisons of mitochondrial gene order revealed a higher frequency of gene rearrangement among lineages with a parasitoid lifestyle, particularly prominent in Chalcidoidea.

With advancements in sequencing techniques, it's now possible to gain deeper insights into this molecule. By understanding how many genes there are, how they're organized within the molecule, identifying the presence of spacers, and analyzing the composition of the D-Loop, we can better grasp the rearrangements that play a crucial role in the evolutionary dynamics of mitochondrial DNA. Additionally, phylogenetic analyses benefit significantly from having access to a larger pool of mtDNA genes. This wealth of genetic information allows for the establishment of evolutionary relationships with greater accuracy than ever before, providing a more robust framework than analyses based on a limited number of genes. Studies on mitogenomes belonging to the family Formicidae have proven promising, enabling the identification of gene rearrangements and enhancing our understanding of the internal relationships within the group. Despite this, the number of mitogenomes available for the subfamily Ponerinae is still limited, and here we present for the first time the complete mitogenome of Odontomachus. Our data reveal a gene duplication event in Formicidae, the first involving trnV, and new gene arrangements involving the trnM-trnI-trnQ and trnW-trnC-trnY clusters, suggesting a possible synapomorphy for the genus.
