![]() ![]() We investigated the relationships among populations using mitochondrial ND4 nucleotide sequences and single nucleotide polymorphisms (SNPs) from the nuclear genome. This frog was once known from mid-eastern New South Wales to eastern Victoria, and evidence from wildlife atlas databases and targeted searches indicate that it has declined in large portions of its former range, leaving several populations that are isolated, in some cases restricted in distribution, and of small size. Several lines of evidence indicate that Litoria littlejohni is such a species. The generality of this pattern has been difficult to discern, especially for those species that are encountered rarely because they have restricted periods of calling activity with poorly defined habitat preferences, and are not common. Population declines and range contractions among Australian frogs that commenced in the early 1980s continue in some species that were once widespread. ![]() ![]() South Australian Museum, North Terrace, Adelaide, Adelaide, 5000, Australia.
