Distribution and Habitat

Country distribution from AmphibiaWeb's database: Australia

 

View distribution map in BerkeleyMapper.
Southern-central regions of Western Australia from Carnarvon in the north to Kalgoorlie in the south-east. The extent of occurrence of the species is approximately 436900 km2

Life History, Abundance, Activity, and Special Behaviors
Sparsely vegetated claypans subject to flooding. Spends most time buried emerging after rain. Breeds after summer rains flood the claypans. Eggs are laid in claypans and tadpoles develop in 40 days.

Trends and Threats
No known declines and extent of occurrence > 20,000km2.

Threats
None known.

Conservation Measures
None in place.

Comments
This species is diploid (Novikova et al. 2020).

This species was featured as News of the Week on 30 November 2020:

While common in plants, whole genome duplication, or polyploidy, is rare in animals. The animals that are polyploid tend to reproduce asexually. Notable exceptions in the amphibian world that display both polyploidy and sexual reproduction, include members of the Xenopus genus and Bufotes viridis complex. Novikova et al. (2020) investigated another system in the Australian genus Neobatrachus, where six members are diploid and three are tetraploid, to better understand the evolutionary role of polyploidism. They found asymmetric gene flow from the more isolated diploid species to tetraploids, which have wider distributions, as the origin of the polyploid species. Furthermore, these inter-specific hybrid tetraploids displayed more wide-spread gene flow and were more tolerant of climate-induced habitat loss, providing a potential rescue effect to species diversity in the genus.
