These data and analyses support the research article "Culture, cryobanking and passaging of karyotypically validated native Australian amphibian cells" Mollard (2018) [1]. The data and analyses presented here include: (1) three additional karyomaps of cells from the cryobanked and passaged frog and tadpole species ; and (2) combined short-to-long arm ratios of the four karyomaps measured from each respective animal here and in Ref [1].

To elucidate the control mechanism of tail resorption during metamorphosis, the expression of , a macrophage-apoptotic cell bridging molecule that promotes phagocytosis in mammals, was examined. In both and , the expression in the tail increased significantly during metamorphosis, reaching its peak at the metamorphic climax, when the tail shortens rapidly. This finding suggests that the up-regulation of at metamorphic climax is involved in the clearance of apoptotic tail muscles.

Teeth have been a prominent feature of most vertebrates for 400 million years, and the core regulatory network underlying embryonic tooth formation is deeply conserved. In frogs, however, odontogenesis is delayed, occurring instead during the postembryonic metamorphosis and resulting in teeth that are restricted to the upper jaw and palate. Developmental-genetic mechanisms that underlie tooth formation in frogs are poorly understood.

Background: The horned frog population, previously identified as from Jiulong County, Sichuan Province, China, was recently proposed to be , based on geographical inference, which remains unconfirmed by specimen examination.
New Information: We revisited this population and confirmed its identification as in Jiulong County using molecular data from 16S and CO1 genes, complemented by morphological diagnosis. Additionally, we described its tadpoles and advertisement calls, extending the known range and informing conservation efforts.

Conclusions about the adaptive significance of phenotypic traits typically rely on correlations between the trait and fitness, but pleiotropic effects of a single trait on fitness and covariation among traits can confound such comparisons. For example, a trait may have several benefits or costs which may be affected by its correlation to some other trait. We overcame this barrier by using CRISPR-Cas9 in captive cane toads () to create gene-knockout albinos.

The Pickersgill's reed frog, Hyperolius pickersgilli (Raw 1982), is an Endangered frog species endemic to a narrow central coastal region of KwaZulu-Natal, South Africa. The Johannesburg Zoo's Amphibian Research Project breeds H. pickersgilli for release to the wild.
