Palearctic green toads (Bufo viridis subgroup) represent one of the few vertebrate systems with three bisexually reproducing ploidy levels that can form population systems where up to three ploidy levels interact reproductively. ...

Previous studies on the Bufo viridis complex, which is distributed broadly across Iran, are incomplete and

restricted to a few regions or a few samples. In this paper a new detailed study on the B. viridis complex ...

The cytogenetic data of

Bufo variabilis

populations in northwest and southeast of Iran are rare, so, it is highly important

to describe the karyotypic details of unexamined populations of variable toads from these regions...
