“…The greatest number of contacts coincide with the Carpentarian, Burdekin-Lynd, Burdekin, McPherson and Mallee barriers. Secondary contacts in lower south-west of Western Australia have been produced by a westward expansion of eastern vicariants, either from the south-eastern or palaeo-South Australian refuge (Keast 1961;Ford 1974b;Serventy & Whittell 1976), whereas many of the contacts in the eastern Mallee belt are due to eastward expansions of either south-western or palaeo-South Australian isolates (Keast 196 1;Ford 1974bFord , 1986Schodde 198 1). In differential expansions, the drier adapted form has invariably dispersed the greater distance (e.g.…”

Summary Ford, J. (1987). Hybrid zones in Australian birds. Emu 87, 158-178.Geographic patterns in positions of 79-87 avian hybrid zones and 12 parapatric contacts in Australia are analysed in the context of past climates, palaeo-refugia, mechanisms of origin, and temporal stability. No hybrid zone occurs in rain-forest species and differentiated vicariant forms of these are generally separated by unsuitable tracts of sclerophyll forest or savanna woodland. Most hybrid zones occur in semi-arid and sub-humid species. The zones appear to have originated by secondary contact of differentiated vicars rather than by parapatric divergence, because most lie between refugia postulated on the basis of late Pleistocene climates; their widths are generally in accord with those predicted from dispersion rates. The evidence suggests that most, if not all, hybrid zones were formed when expansion of isolates from refugia became possible following the marked improvement in climate at the close of the severe arid phase of about 17 000 y before present. The persistence of hybnd zones since then and their widths offer no support for the concept of reinforcement of previously acquired differences in recognition (signalling) systems. Where a hybrid zone coincides closely with the boundary of a presumed refuge, a semiarid form has differentially expanded towards its subhumid counterpart.

“…the northern subspecies of the Brown Treecreeper, occurs from the Burdekin-Einasleigh divide northwards up Cape York Peninsula (Ford 1986). In the southern part of its range, from the Atherton Tablelands west to the Gulf of Carpentaria, it is still reasonably common, having been recorded during the period 1977-81 in 18 of about 21 possible one degree squares (Blakers et al 1984).…”

Mesic southeastern Australia represents the continent's ancestral biome and is highly biodiverse, yet its phylogeographic history remains poorly understood. Here, we examine mitochondrial DNA (mtDNA) control region and microsatellite diversity in the brush-tailed rock-wallaby (Petrogale penicillata;n = 279 from 31 sites), to assess historic evolutionary and biogeographic processes in southeastern Australia. Our results (mtDNA, microsatellites) confirmed three geographically discrete and genetically divergent lineages within brush-tailed rock-wallabies, whose divergence appears to date to the mid-Pleistocene. These three lineages had been hypothesized previously but data were limited. While the Northern and Central lineages were separated by a known biogeographic barrier (Hunter Valley), the boundary between the Central and Southern lineages was not. We propose that during particularly cool glacial cycles, the high peaks of the Great Dividing Range and the narrow adjacent coastal plain resulted in a more significant north–south barrier for mesic taxa in southeastern Australia than has been previously appreciated. Similarly, located phylogeographic breaks in codistributed species highlight the importance of these regions in shaping the distribution of biodiversity in southeastern Australia and suggest the existence of three major refuge areas during the Pleistocene. Substructuring within the northern lineage also suggests the occurrence of multiple local refugia during some glacial cycles. Within the three major lineages, most brush-tailed rock-wallaby populations were locally highly structured, indicating limited dispersal by both sexes. The three identified lineages represent evolutionarily significant units and should be managed to maximize the retention of genetic diversity within this threatened species.
