Studies on the Fire Bellied Toad (Bombina bombina (Linnaeus, 1761)) and Yellow Bellied Toad (Bombina variegata (Linnaeus, 1758)) of Upper Silesia and Moravian Gate
Abstract:
PREFACE. The field study and collection of material for the present paper were carried out in 1959-1961: in the Polish territory in 1959-1960 and in Czechoslovakia in 1960-1961. A total of over 2000 specimens were collected from 251 localities. As the material included both of the European species of Bombina and was sufficiently abundant, it was used not only for a physiographic study but also to analyse specific characters statistically. Thus, two parts of the paper sprang up, each on a different subject: the taxonomic part and the physiographic one. This division into two parts seems to have been necessary considering the dissimilarity of the problems dealt with as well as the fact that the reader is not always interested in both questions.
