Based on this analysis, we show that populations inhabiting the eastern part of the range of the former species Ahaetulla nasuta auctorum, namely Myanmar and the Indochinese Region, should be referred to Ahaetulla fusca (Duméril, Bibron et Duméril, 1854), a taxon we here resurrect from synonymy at species level. Its neotype is redescribed. We also discuss the status of populations inhabiting Myanmar.

The obtained mitochondrial genome was 17, 945 bp in length, comprising 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes and an incomplete control region (D-loop). Another nearly complete mitogenome of P. liui, from north of the Yangtze River, was retrieved from GenBank and used for comparative analyses. The results showed that the genome organization, base composition, codon usage, and gene arrangement of the mitochondrial genomes for the two individuals of P. liui were highly similar to each other. Twelve out of 13 PCGs initiated with canonical start codon (ATG), while COX1 started with GTG. The codon usage analysis revealed a preferential use of the LeuCUN, Pro, and Thr codons with the A/U ending. Among the 22 tRNA genes, only tRNA-SerAGY was not folded into a typical cloverleaf secondary structure and had no recognizable DHU stem. The phylogenetic tree inferred from Bayesian inference and maximum likelihood approaches strongly supported that the two individuals of P. liui clustered together, and formed the sister taxon to a clade of P. capito and P. tunganus. All PCGs had undergone a strong purifying selection, whereas 27 residues of the ATP6, COX2, Cytb, ND3, ND4, ND5, ND6 genes might have undergone positive selection. Bayesian molecular dating indicated that the split between P. liui and P. capito – P. tunganus was approximately 9.62 million years ago (Ma). Meanwhile, the coalescence time of the two individuals of P. liui was estimated to be 2.26 Ma with 95% highest posterior density of 1.32 – 3.28 Ma, which fell within the timeframe for the Yangtze River run-through between the late Pliocene to the middle Pleistocene. This finding implied that the Yangtze River run-through had played an important role in the diversification of the Liu’s skink.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48411961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially in the glaciation period, Amanos Mountains in the Middle Taurus as an isolating barrier appeared unsuitable habitats for the lineages of C. ocellatus.

Here, we evaluate composition of species in freshwater ecosystems (main river courses) and terrestrial ecosystems (forests) in two distinct regions using Visual Encounter Surveys along designed transects, examination of fishers’ catches and standardized interviews. In Northern Laos, we recorded only 18 reptile individuals (2 turtle and 1 snake species). Interview surveys demonstrated that in Nam Xam River, fishers are more likely to hunt turtles and we identified one potential site where the world’s rarest turtle, Rafetus swinhoei, could be still present in the wild. In Nam Et Phou Louey National Park, we found 19 reptile species (8 lizard, 10 snake, 1 turtle species) in the different study sites, demonstrating a low species density in all different surveyed habitats. In Central/Southern Laos, we observed 30 species of reptiles (14 snake, 16 lizard, 35 amphibian species). Our study offers preliminary insights into the composition of amphibians and reptiles in Laos. The great majority of the species were non-threatened or not evaluated, and a few were threatened, suggesting that more research is needed to proper understand the conservation status of Laos’ herpetofauna. We highlighted, indirectly by interviews with local fishers, the possible presence of the turtle Rafetus swinhoei, thus providing a new hope for avoiding the extinction of this species. Finally, we observed a relatively low number of species in each habitat type, which is remarkably lower than in tropical forests of other continents or of nearby south-east Asian countries, indicating that the herpetofauna communities in Laos are depleted, reflecting an ‘empty forest syndrome’.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44143849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
