Biological Investigations of Bufo gargarizans Cantor 1842 on Southern Sakhalin

Hans-Werner Herrmann, E. Kabisch


In field studies on Bufo gargarizans Cantor 1842, in the south of the Far Eastern island Sakhalin data were obtained about the intraspecific variabllity in pattern, biometrical measurements and ecological conditions of the breeding sites. Detailed investigations about ethology, nutrition, larvae and micromorphology of epithelial structures were carried out under field conditions and in the laboratory. The results confirm the postulation that Bufo gargarizans is a valid species. The special ethological and pattern characteristics of the Sakhalin populations are discussed.
