In Experiment 1 lizards from both islands showed higher tongue flick rates to cotton swabs bearing snake and prey chemicals than to controls. Lizards from Hachijo-kojima emitted more tongue flicks to snake chemicals than those from Kozu-shima. In Experiment 2 lizards from Hachijokojima showed higher tongue flick rates to cotton swabs bearing non-saurophagous, allopatric snake chemicals than to control stimuli. Lizards from Kozu-shima exhibited tail wave display, which may deflect attacks to the autotomous tail, more frequently to saurophagous snake chemicals than to non-saurophagous snake and control stimuli, but there were no significant differences in tongue flick rates among the three chemicals for these lizards. In Experiment 3 lizards were introduced into an unfamiliar terrarium treated with snake chemicals. Lizards from Hachijo-kojima emitted more tongue flicks in cages chemically labelled by snakes than in control cages. No significant differences were observed in tongue flick rates between snake labelled and control cages in Kozu-shima lizards, and their tongue flick rates in snake labelled cages were significantly lower than those of Hachijo-kojima lizards. There were no differences in the frequency of tail waves, wall-climbing, movements, or immobility between snake labelled and control cages in lizards from both islands. Based on the higher tail wave frequency and lower tongue flick rates in Kozu-shima lizards than in Hachijo-kojima lizards, we hypothesize that lizards from Kozu-shima have evolved the ability to recognize chemical cues from snake predators after a few tongue flicks and that the higher tongue flick rates by lizards from Hachijo-kojima indicate less efficient recognition or lack of recognition of predator chemicals.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125256358","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}

Some authors adopt a subspecific name, R. t. formosanus, whereas others negate taxonomic subdivision of R. tigrinus. We compared external characters and karyotype between the Taiwanese and other populations. Results indicate that the former has a unique W chromosome, which is metacentric and distinctly smaller than the Z chromosome. The Taiwanese populations also differ from others, except for populations of Kyushu, Japan, in having more subcaudals (80≦in males, 77≦in females). From the Kyushu populations, Taiwanese R. tigrinus is distinct in having 15 or more lateral dark blotches between the neck and the 50th ventral (14≧in the former). All these characters, as well as deduced East Asian paleogeography, strongly suggest that the Taiwanese populations have been constituting an independent evolutionary unit by themselves since their entry into this island from the southeastern continent. Thus, we consider that they deserve recognition as a distinct taxon and tentatively retain them at the subspecific status as R. t. formosanus.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131992012","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}

This volume, consisting of 28 articles and seven notes all devoted to the systematics, ecology, physiology, and conservation of the European pond turtle (Emys orbicularis) populations, is reviewed in the light of its significance as a first step toward the international exchange of information/experiences for the comprehensive understanding of this widely distributed, but locally differentiated and threatened species. All the articles and notes, though arranged in a rather curious way, contribute much to our knowledges of this systematically interesting and conservationally important turtle, which, until recently, had been poorly studied from the viewpoint of population biology. Reading of this book, one can realize the importance of integrative approaches for the designation of effective conservation measures, especially for a wide-ranging polymorphic organism like this species. This volume is thus recommended for the bookshelves of all students interested in this and relevant fields of biology. Applications of a few other methods/techniques, such as the multivariate analysis of morphological characters and allozyme electrophoresis, are recommended to further improve the evaluation of taxonomic status and conservation priority for local populations of this turtle. Establishment of the criteria and guidelines for international translocation-based conservation procedures seems to be an urgent necessity.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121927684","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}

Males of R. nigromaculata were significantly larger and heavier than those of R. porosa brevipoda. Mixed-species choruses were formed by male R. nigromaculata joining the choruses of R. porosa brevipoda. In the mixed-species choruses, males of both species defended their own calling spaces against both conspecifics and heterospecifics. Most of the interspecific agonistic interactions were initiated by male R. nigromaculata, and most of the interactions were terminated by the victory of R. nigromaculata, probably due to its larger body size. Males of the two species emitted similar calls: advertisement calls with multiple notes and encounter calls with a single note. Advertisement calls of R. nigromaculata consisted of fewer notes and were lower in frequency than those of R. porosa brevipoda, although there was a considerable spectral overlap between the two species. Males of both species with SVL of approximately 65mm emitted calls of similar dominant frequency. Playback experiments were performed to examine the response of the males to conspecific and heterospecific advertisement calls. Male R. porosa brevipoda tended to respond to only conspecific calls, whereas male R. nigromaculata tended to respond to both conspecific and heterospecific calls. This indicates that male R. nigromaculata do not distinguish heterospecific calls from conspecific ones. Heterospecific pairings and hybridization were observed within the mixed-species choruses. Two types of possible costs, energetic costs and hybridization, caused by the asymmetric interspecific interactions are discussed.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416537","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}
