Rana kukunoris is endemic to the eastern Tibetan plateau and its breeding ecology was not known so far.

Our results showed that clutch size and total clutch volume increased with maternal body size. However, no significant correlation between egg number and egg size was observed, which suggested that the tradeoff between offspring number and size in this species was lack.
