“…The major genetic break between the northern and southern Arenophryne haplotypes is consistent with the genetic differences observed between sister species in other groups within the Myobatrachidae (Morgan et al, 2007;Read et al, 2001). As a result of this work clear morphological differences have been measured and a new species description corresponding to the southern haplotype clade is forthcoming (Doughty and Edwards, submitted ms).…”

“…Targeted DNA was amplified using a touch-down PCR profile: 94°C for 5 min-1·; 94°C for 30 s, 70-45°C (decreasing in 5°C increments) for 20 s, 72°C for 90 s-each of these cycles were repeated 2· for each extension temperature; 94°C for 30 s, 40°C for 30 s, 72°C for 45 s-40·; 72°C for 4 min-1·; 4°C held.

“…While nothing is known about the history of this species, given the considerable molecular genetic divergence between Arenophryne and it's closest relatives, Myobatrachus gouldii and Metacrinia nichollsi (Read et al, 2001), older climatic and geological events may have impacted the current genetic architecture of A. rotunda. The distribution of A. rotunda crosses many significant geological entities within the Shark Bay region, namely the northern border of the Victoria Plateau and the Murchison Gorge (Fig.…”

“…The sunset frog is classified as 'Vulnerable' under IUCN Red List criteria (Burbidge and Roberts 2001). The species, discovered in 1994, is the single survivor of a lineage within the family Myobatrachidae most closely related to the genus Uperoleia (Roberts et al 1997;Read et al 2001). It is an aquatic ovipositor with aquatic larval development that breeds in late spring or early summer when rainfall is lowest in southwestern Australia (Burbidge and Roberts 2001), a breeding strategy unique in the south-western Australian frog fauna and likely to be an ancestral state retained from historical occupation of a subtropical region (Roberts et al 1997).…”

Abstract. Outlining the distribution of genetic variation, patterns of gene flow and clarifying the biogeographic processes underlying population history are critical components of a comprehensive conservation strategy for endangered or vulnerable species. We provide this information for the vulnerable sunset frog (Spicospina flammocaerulea) using a comprehensive genetic dataset (ND2) with samples from 17 of 22 geographic localities where this species has been found. From genetic, biogeographic and coalescent-based analyses, we document the existing genetic variation, likely movement patterns and explore the biogeographic history of S. flammocaerulea. While catchment-based genetic variation is well documented in other high-rainfall taxa in south-western Australia, a much more complex scenario including dispersal across ridge lines between catchments better explains the distribution of genetic variation and observed patterns of gene flow in S. flammocaerulea. The population history of S. flammocaerulea is strongly indicative of recent population contraction and expansion, which may be related to late Pleistocene climate fluctuations. This suggests that this species can adapt or move in response to fluctuating climates provided suitable habitats or expansion areas are available. However, like many other endemic taxa with limited geographic ranges in south-western Australia, the potential to shift distributions is hampered by being land-locked within an agricultural landscape, limiting management options in the face of climate change.

Anurans breed in a variety of aquatic habitats with contrasting levels of desiccation risk, which may result in selection for faster development during larval stages. Previous studies suggest that species in ephemeral ponds reduce their developmental times to minimize desiccation risks, although it is not clear how variation in desiccation risk affects developmental strategies in different species. Employing a comparative phylogenetic approach including data from published and unpublished studies encompassing 62 observations across 30 species, we tested if species breeding in ephemeral ponds (High risk) develop faster than those from permanent ponds (Low risk) and/or show increased developmental plasticity in response to drying conditions. Our analyses support shorter developmental times in High risk, primarily by decreasing body mass at metamorphosis. Plasticity in developmental times was small and did not differ between groups. However, accelerated development in High risk species generally resulted in reduced sizes at metamorphosis, while some Low risk species were able compensate this effect by increasing mean growth rates. Taken together, our results suggest that plastic responses in species breeding in ephemeral ponds are constrained by a general trade-off between development and growth rates.
