“…Thus, for processed food, the approach based on a single locus could require a second step with a complementary marker for the identification in the case of sister species or complex evolutionary patterns. In our study, the new primer pair is designed on D-loop, a regulatory non coding region with high potential power for species identification (Karaiskou et al, 2004;Lalitha & Chandavar, 2018). Such region has proven to be helpful for discriminating, to species level, the complex of S. colias-S. japonicus-S. australasicus, as already found for Thunnus genus and S. japonicus haplotypes (Mariani et al, 2015;Viñas & Tudela, 2009;Yan et al, 2015).The two-step barcoding approach, already suggested for other taxa (Jin et al, 2018;Pawlowski et al, 2012), consists in a first step, in which universal primers are used to reach at least the genus level, followed by specific primers targeting problematic taxa.…”

“…Although the CR is usually thought to be the fastest-evolving region of the mitogenome ( Brown, George & Wilson, 1979 ), few reports explored the usefulness of the CR in phylogenetic analyses of lizards ( Lalitha & Chandavar, 2018 ). Our study evidenced that this region may be highly informative for a variety of studies of the genetic variability of mitogenomes in lizards.…”

Liolaemus is the most specious genus of the Squamata lizards in South America, presenting exceptional evolutionary radiation and speciation patterns. This recent diversification complicates the formal taxonomic treatment and the phylogenetic analyses of this group, causing relationships among species to remain controversial. Here we used Next-Generation Sequencing to do a comparative analysis of the structure and organization of the complete mitochondrial genomes of three differently related species of Liolaemus and with different reproductive strategies and ploidy levels. The annotated mitochondrial genomes of ca. 17 kb are the first for the Liolaemidae family. Despite the high levels of sequence similarity among the three mitochondrial genomes over most of their lengths, the comparative analyses revealed variations at the stop codons of the protein coding genes and the structure of the tRNAs among species. The presence of a non-canonical dihydrouridine loop is a novelty for the pleurodonts iguanians. But the highest level of variability was observed in two repetitive sequences of the control region, which were responsible for most of the length heterogeneity of the mitochondrial genomes. These tandem repeats may be useful markers to analyze relationships of closely related species of Liolaemus and related genera and to conduct population and phylogenetic studies.

“…Additionally, here we have to note that only mitochondrial markers were used in this study. These are widely used in phylogenetic studies [37,[44][45][46][47], although they do not provide any information if hybridisation has taken place between certain lineages. Whereas hybridisation is highly plausible in the study area, since several sampled populations show mixed-lineage origin (see Fig.…”

Background Pikes, members of genus Esox, are widespread freshwater predators of the northern hemisphere, and important sport fish also. From the Carpathian basin only one species, the northern pike (E. lucius) is noted. At the same time the pike stocks living in this area show high level of phenotypic variance (e.g. various body pattern) and its growth varies highly both among and within populations. These features usually explained by the environmental diversity of the area. Whereas we think that genetic reasons -e.g. the appearance of other/new pike species in the area- may also be responsible for these observed features. Since as no detailed information have been published from the pike populations of this area, so far; we conducted phylogenetic and morphological assay on 88 pike specimens, collected from 49 Middle Danubian sampling sites. Results Our phylogenetic surveys showed that the northern pike appear in the study area solely, but all the three of its major lineages (Northern, Circumpolar, Southern) were indicated. Only six specimens represent the Northern lineage, collected from the western part of the study area. The Circumpolar and Southern lineages were common in the Carpathian basin, but the Southern lineage showed higher levels of haplotype diversity than the Circumpolar clade. Which indicates that only the Southern lineage is native in the area, while the other two groups could have appeared in the Middle Danubian system either spontaneously or by human introduction. Moreover, the different clades appeared in the same populations, suggesting the opportunity of inter-lineage hybridisation. From the studied morphologicalal features, the number of scales on the lateral line and the head length showed significant differences among the lineages. At the same time the body pattern of the studied individuals seems to be rather influenced by the ontogenic changes than phylogeny. Conclusions The high phenotypic variability of Middle Danubian northern pike populations may be due that all of its three major clades appeared and came in secondary contact in the area. In the within watershed spread of the non-native lineages the human stocking/transfer may play a considerable role.
