Neobatrachus pictus, common name - painted burrowing frog.
The painted burrowing frog (Neobatrachus pictus) is one of six diploid species in an Australian diploid-tetraploid species complex. The three tetraploids tend to occupy harsher habitats. Strikingly, genomic analyses show that the tetraploids are not completely genetically isolated from each other or the diploids, which in contrast are genetically isolated. Modelling of ecologically suitable areas for each species through time and genomic estimates of demographic histories, indicate that the diploids may be suffering the early genomic impacts of climate-induced habitat loss, while tetraploids appear to be avoiding this fate, possibly due to widespread gene flow.
