In the southwestern USA and northern Mexico, where C. p. bellii is the expected native race, populations are small and widelyscattered. Introduced populations of other painted turtle subspecies are reported from various locations in the USA. We discovered a small but dense introduced population of C. p. marginata on the Colorado Plateau in northern Arizona, a region with few, if any, turtles due to aridity and an elevated topography with little surface water. The turtles were in a remote pond constructed to provide cattle with water. Chrysemys p. marginata occur naturally east of the Mississippi River, over 2,000 km away. The nearest native population of C. p. bellii in Arizona is over 160 km away. We observed nesting females, juveniles, and the presence of shelled eggs in females via Xradiography confirming a self-sustaining population. The body sizes and nesting season we observed were consistent with data for those variables from native populations of the taxon. It is unknown exactly how the turtles came to be established in such a remote location, but it is unlikely that they will spread due to the scarcity of perennial water sources in the semi-arid region. Due to increasing drought frequency and duration in the region, small populations like this one, introduced into a novel environment, may be bellwethers for monitoring the effects of climate change.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":"38 1","pages":"91 - 98"},"PeriodicalIF":0.7,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45131278","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}

Endemic species often have a very restricted range, making them extremely vulnerable to stochastic events and human activities, including poaching. Previous studies have shown that several species endemic to the Nansei Islands in Japan are available in the international pet trade. This paper further investigates the presence of live reptiles and amphibians endemic to the Nansei Islands in international pet trade. Seven Facebook groups and five classified websites were searched for these species, in addition to the CITES database and a spotcheck at Chatuchak market in Thailand. Nansei Island endemic reptiles and amphibians are more common in the international pet trade than initially thought. During the study period, advertisements for 23 species endemic to the Nansei Islands were found, comprising a total of 360 specimens. In addition, during a spot-check, 8 individuals of 2 subspecies of Japanese sword-tail newt were found at Chatuchak market in Thailand. Only three of these species are protected by the CITES and nine are regionally or nationally protected. Yet, ten species observed in international markets are classified as Endangered by IUCN and two even as Critically Endangered. The large numbers observed for the Endangered and Critically Endangered Goniurosaurus and Takydromus species warrants increased protection and a CITES Appendix III listing is recommended for these species.","PeriodicalId":56053,"journal":{"name":"Current Herpetology","volume":"38 1","pages":"109 - 99"},"PeriodicalIF":0.7,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48724945","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}
