[Differences in muscle thermostability between diploid and tetraploid species of green toads (Bufo viridis complex) of Middle Asia].

Significant differences were found between diploid (Bufo viridis) and tetraploid (B. danatensis) toad species in their skeletal muscle thermostability. The lower muscle thermostability in tetraploids may be associated with the adaptation of B. danatensis to colder conditions of arid mountain area in the Middle Asia.
