Scanning electron microscopy was used to observe the scales, which were peeled off from the middle back of the snakes. The results revealed significant differences in the microdermatoglyphic structure patterns between the two families, Viperidae and Elapidae. Viperidae exhibited a “polygonal” structural unit, while Elapidae displayed arcs, pores, and strips as their basic structure. Additionally, there were notable differences in ultrastructure within each family. In Viperidae, Ovophis makazayazaya had a flat structural unit, Trimeresurus stejnegeri had a mound-like uplift near the center with a flat surrounding, and Protobothrops mucrosquamatus had an overall uplifted structure. In Elapidae, Ophiophagus hannah showed obvious differences in the size and arrangement of arc structures. The intraarc structure of Bungarus multicinctus resembled vertebral bodies, while that of Sinomicrurus peinani was columnar in shape. The ultrastructural characteristics of snake scales generally exhibited essential differences among advanced taxonomic units. However, there were detailed differences among species within the same family or genus. The initial formation of microornamentation features in scales may be related to the snakes’ habitat environment. Species formation through isolation is accompanied by the differentiation of these characteristics, and once species formation occurs, the features remain stable until the next species differentiation. There were instances of similar structures found in species with distant evolutionary relationships. This suggests that the microdermatoglyphic structure has taxonomic significance but may not necessarily have phylogenetic significance.","PeriodicalId":508509,"journal":{"name":"Russian Journal of Herpetology","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141673647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides important information on animal morphology and evolutionary ecology because it allows us to identify key morphological and functional traits between sexes and infer intraspecific competition. In this study, we measured the morphological characters of 147 individuals of three pit viper species stored in the archive of the National Institute of Biological Resources of the Ministry of Environment and confirmed interspecific differences and sexual size dimorphism of each species. We also identified important characters affecting identification using linear discriminant analysis. The results showed that the three pit viper species differed in body and head morphology, and the number of dorsal scale rows was the most important character for species identification. It was found that female red-tongued pit vipers and short-tailed pit vipers were larger than males of each species, while male Central Asian pit vipers were larger than females. Characters related to tail length and head length were confirmed as important characters for interspecific sex discrimination. We compared characters related to head morphology between sexes to find that red-tongued pit vipers showed differences in most characters, while short-tailed pit vipers and Central Asian pit vipers did not. Therefore, short-tailed pit vipers and Central Asian pit vipers are expected to have strong intraspecific competitive pressure. In future studies, it will be necessary to conduct a detailed research on intraspecific competition of short-tailed pit vipers and Central Asian pit vipers with little morphological differences between sexes by examining resource utilization (e.g., food sources and habitats) and ecological niche.","PeriodicalId":508509,"journal":{"name":"Russian Journal of Herpetology","volume":"96 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
