The olive ridley sea turtle (Lepidochelys olivacea; Cheloniidae) demonstrates extreme instability of pholidosis, and the aim of our study is to identify the range of the carapace scute variations in this species. We studied 655 L. olivacea hatchlings from nine natural clutches on the Southern coast of Sri Lanka and identified 120 different patterns of carapace scutes. The vertebral and pleural scutes were the most variable, ranging in number from four or five to ten. Five pairs of pleural scutes, a normal condition for some species of sea turtles, were found in only 11.9% of individuals. The hatchlings with six and seven scutes in the vertebral and pleural series were the most numerous. 13 pairs of marginal scutes were the stable norm in 92.7% of individuals. Newborn turtles with symmetrical scute patterns predominated (60.9%). Comparison of the pholidosis variability in hatchlings from different clutches revealed the presence of specific scute patterns. We assume that the clutch differences are more related to the genetic characteristics of the breeding turtles than to the influence of environmental factors. The unique variable pholidosis of L. olivacea demonstrates a trend toward scute polymerization, a rare phenomenon in turtle evolution.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140668829","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}

The first signs of texture in the form of dark stripes and spots appeared in tadpole skin at stages G39 – 40. At G41 – 44, the body of the tadpole acquired a typical «frog» position with an orientation of 20 – 30° to the substrate, dorsolateral stripes transformed into folds, and dark spots into tubercles in the caudo-rostral direction. At the end of metamorphosis (G45 – 46), the texture formation was completed on the entire back, and the type of morph (striata, non-striata) was easily determined. The period between the first signs of the appearance of skin texture and its complete formation took 6 – 12 days. The most stable was the interval between the primary protrusion of the forelimbs under the skin and the eruption of the first one (~12 h). The period between the eruption of the first and second forelimbs was the most variable (from an hour to three days). The results obtained highlight the plasticity and problematic nature of the phenomenon of metamorphosis in amphibians.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140672337","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}

The ecological niche modelling studies enable us to predict suitable habitat areas for each species according to the interaction of climate and taxa in the past, present, and future. The aim of this study was to investigate the possible effects of climate change on the Lacerta diplochondrodes species, which is distributed in Europe and Türkiye. Applying the ecological niche model, suitable habitats of the species were projected in the Last Glacial Maximum, current and future. The future climate scenarios in the 2050s and 2070s, we used BCC-CSM1-1, GISS-E2-R, HADGEM2-AO, MIROC5, and MPI-ESM-LR with rcp2.6 and rcp8.5. The suitability of habitats was projected to decrease by 10.56 – 13.53% depending on the scenario with rcp2.6 and by 21.83 – 35.99% depending on rcp8.5 in the future. In future climate scenarios, it is estimated that suitable habitat areas will decrease in Europe, while suitable habitat areas in Türkiye will remain largely unchanged. As part of the conservation efforts of this species in Europe, we recommend that monitoring and conservation studies be undertaken as soon as possible. In Türkiye, it is recommended that the region from the south of Central Anatolia towards the Aegean region should be studied primarily to minimize habitat loss due to climate change in the future.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140670811","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}

The process of formation of the epidermis and dermis, as well as their derivatives (epidermal scales and dermal ossifications), is described. The development of epidermal scales in Pelodiscus maackii has been shown to be similar to the development of asymmetric scales in other reptiles. Five stages of formation of the definitive structure of the dermal bones have been identified. Structural differences between the internal and external parts of the bony plates (rod-shaped elements and bony callosities) are due to the previous stratification of the dermis into histologically distinct strata: hypodermal, fibrous and papillary. In particular, the fibrous stratum, consisting of several layers of orthogonally oriented collagen bundles, is a precursor to the plywood-like structure of the trionychid bony plates. The growth of bone tissue around the vascular network in the papillary layer is the reason for the formation of surface ornamentation of the trionychid callosities. Some questions of the evolutionary significance of the unique features of the trionychid shell are discussed.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140413766","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}

Until recently, only rare records of tree frogs were observed here, which are probably associated with introductions or penetration of the species from border regions of Lithuania and Poland. However, in the period 2007 – 2022 we revealed here 41 new localities of Hyla orientalis throughout the southern part of Kaliningrad Oblast’. In all studied localities, where we found mating tree frogs, shallow fish-free puddles surrounding by agricultural fields were used as breeding habitats. Local populations of the species are quite abundant. The northern boundary of native range of H. orientalis in 1940 was on the adjacent territory of north-eastern Poland. Thus, we recorded a shift to the north of the range boundary of the species by approximately 30 – 40 km over the past 82 years. This is most likely is related to global warming. In the region, the average temperature and the amount of precipitation are increasing, which lead to favorable conditions for the long-term existence of warm puddles in the fields, in which tadpoles can successfully and more rapidly develop. The appearance of a large number of such biotopes allowed this species to successfully populate this territory.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140414429","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}
