For the first time the karyotype of Bufo eichwaldi was described (2n = 22). It consists of 12 large metacentric (V), 8 small metacentric (v), and 2 small submetacentric chromosomes (sv): 12 V + 8 v + 2 sv, NF = 44. According to the number of chromosomes and arrangement of NORs (in the end of long arms of pairs 6), the karyotype of B. eichwaldi has no differences from karyotypes of close related B. bufo and B. verrucosissimus. The main difference is wide heterochromatin C-blocks in long arms of pair 10, which is present in B. eichwaldi and lacking in B. bufo and B. verrucosissimus. Moreover, in the Eichwald’s toad the pair 1 has, as a rule, larger size if compare with other two species. Additionally, these two species had two submetacentric chromosomes (pairs 4 and 7), but B. eichwaldi had only one (pair 7).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
