Using skeletochronology, the age and body growth of Tokay Geckos from local populations in Central Java (18 females, 21 males) and in East Java (19 females, 42 males) were studied for the first time. A total of 100 frozen specimens (37 females, 63 males) were used. Sex was determined by observing the presence (male) or absence of pre-anal pores (female). Snout to vent length (SVL) of the smallest female and male with the line of arrested growth (LAG) was 127.1 and 160.4 mm, respectively. Both males and females reach sexual maturity before one year old with 98.3 mm SVL for females and 111.6 mm SVL for males. Analysis of the LAG counts indicated that the age of individuals that were harvested was ranged 0 – 2 years for females and males, with SVL ranging 110 – 182 mm. Growth rates in SVL are much faster in males as compared to females, as well as increasing of MP (width of bone from the edge of marrow cavity to the periosteal outer margin) inside femur bone. The mean SVL of males was larger than that of females. The Sexual Dimorphism Index (SDI) was calculated as -0.28, indicating a sexual size dimorphism in favor of males.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45023149","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}

To investigate this, we use sequences of a partial fragment of mitochondrial ND1 and its flanking region from 248 individuals taken from 30 localities. Analyses reveal low genetic diversity and commonly shared haplotypes. Montane areas exhibit a significantly greater genetic diversity than lowland areas (P 0.01). The origin of P. megacephalus on Hainan Island dates to 1.06 Ma in the Pleistocene. Population expansion events were associated with the transition from the last interglacial period to the last glacial maximum. The matrilineal history indicates dispersal from the montane to the lowland. Bidirectional dispersion occurs between northeastern and southwestern parts of the island. Low FCT values for the northeastern and the southwestern areas associate with rivers, whereas the highest values occur among two geographical groups. Thus, mountains and rivers appear to have effected dispersal. Pleistocene climatic cooling and the creation of a landbridge with mainland China owing to lowered sea levels best explains the occurrence of P. megacephalus on Hainan Island. The analyses provide insights into the effects of Pleistocene climatic fluctuations on an amphibian on Hainan Island.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47215132","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}

Most authors assume that this rarely documented behavior is cryptic and antipredator, e.g., by taking the form of a liana the snake may avoid being attacked by a potential predator. We herein report the first records of this behavior in snakes in Asia and Europe. A dozen cases of body bending are documented for the colubrids Coelognathus radiatus (Boie, 1827), Ptyas carinata (Günther, 1858) and Oligodon joynsoni (Smith, 1917), and Malpolon monspessulanus (Hermann, 1804), and the natricids Fowlea piscator (Schneider, 1799) and Rhabdophis siamensis (Mell, 1931). In addition to the earlier reports from the New World, we suggest that BBB is widespread in snakes throughout the tropical and subtropical world. For a number of species that display it relatively frequently, such as C. radiatus in Thailand, BBB may have a significant adaptive value. We propose that this behavior is basically a kind of defensive immobility response that may develop swiftly or rather slowly and which is most often associated with diurnal activity, open spaces and an inclination to aggressive defenses. Our data suggest that its function is more often aposematic than cryptic.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48168697","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}

So far, the ecology of any of them has not been studied, and here, we document the variation between them. Furthermore, we estimated population density in Papuk using line transects, and quantitatively assessed its viability, i.e., chances for its survival under different scenarios; under current situation, with increased habitat, and with the negative effect of catastrophic events (e.g., forest fires, habitat degradation). Our study suggests that the climate between the two populations differs significantly, while other general requirements of the species remain the same in both locations. In the Papuk area we estimated the total population size from 5036 to 5483 individuals, with a relative density of 97 individuals per hectare. The population viability results suggest that the extinction of the Papuk population is likely to happen due to the negative trend in the number of individuals over 100 years. This implies that the population is not stable and under current condition shows the need for urgent conservation measures. We modeled two measures, 1) restoration of habitat via the removal of black pine plantations, and 2) translocation of the Snake-eyed Skink into two new habitats. Both methods rely on the increase of available habitat, and both were implemented in the study area. In 2014 an area of 900 m2 of black pine forest was removed, and in 2014 and 2016 we translocated 100 individuals per year (altogether 200 individuals) into new habitats. Monitoring data confirmed that the newly established subpopulations are present at both sites, and are reproducing, which could imply that our translocation might be successful.","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47191613","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}
