Fourteen enzymes extracted from skeletal muscles and livers were analyzed by starch-gel electrophoresis. These enzymes were encoded by genes at 20 presumptive loci. There were 3-11 phenotypes produced by 3-9 alleles at these loci. The mean proportion of heterozygous loci per individual, mean proportion of polymorphic loci per population, and mean number of alleles per locus in 11 species were 4.5%, 12.5%, and 1.14 on average, respectively. Genetic distances were 0.036 between two populations of L. infrafrenata; 0.248-1.849 (x=1.135) between nine species of the genus Litoria; and 1.703 between two species from the genus Nyctimystes. The intergeneric genetic distances were 1.551-2.877 (x=1.944) between Litoria and Nyctimystes. The UPGMA dendrogram and NJ tree showed the primary dichotomy of the Papua New Guinean hylids Nyctimystes and Litoria. Our distance data confirmed the presence of several sibling species of Litoria, which are similar to each other in external morphology; i. e., L. arfakiana and L. wollastoni, and L. contrastens and L. bicolor group sp.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127747342","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}

B. torrenticola had one hemoglobin component, irrespective of age and sex, whereas B. b. formosus had two components, one of which is identical with that of B. torrenticola. The banding pattern of B. b. japonicus, showing either one or two hemoglobin components, is identical either with B. torrenticola or B. b. formosus, respectively. This variation in B. b. japonicus seems to indicate the existence of polymorphism within a population. Systematic relationships between these forms and European B. b, bufo were examined in the light of hemoglobin components and other non-biochemical evidences, and it was concluded that the Japanese group have diverged considerably from the European species. INTRODUCTION Biochemical approaches, when adopted in combination with other methods, can be useful in understanding the systematic relations of toads (Matsui, 1974). The most prevalent biochemical technique is the electrophoretic method, with which extensive comparative studies have been made on toads of the genus Bufo (Guttman, 1972). As to the Japanese toads, however, knowlede of biochemical variation among them is still very poor. In this paper will be reported the results of the electrophoretic analysis of the homoglobin of three forms of the Japanese toad. This study was made as a part of an allround investigation to clarify the phylogenetic relationships within Bufo bufo species group. MATERIALS AND METHODS The materials examined were 11 individuals of three forms of toads: the Japanese Japanese Journal of Herpetogy 7(1): 15-19. 1977.","PeriodicalId":348021,"journal":{"name":"Japanese journal of herpetology","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132128151","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}
