“…Areas of endemism for the birds of northern and eastern Australia (Keast. 1961;Ford, 1978;Cracraft, 1982). These areas include: (1) a moist forest track in coastal southeastern Queensland-eastern New South Wales, (2) the Cairns-Atherton rainforest area, (3) the Cape York Peninsula (the historical relationships between the northeast corner, here designated 3a, and the remainder of Cape York is uncertain), (4) the Arnhem Land plateau, and (5) the Kimberley plateau.…”

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.

“…As potential refuges these areas are similarly important for rainforest species (Schneider et al 1998;Williams et al 2003). Mesic and seasonally very dry ecosystems have received far less attention both in terms of studies in endemism and as refuges, and what attention they do receive is generally in the context of rock refuges (Couper and Hoskin 2008;Ford 1977;Freeland et al 1988). Blackbraes is a refuge area aside from values that might exist within its rock habitats, as it provides an unusual example of cooler, higher altitude and tall savanna woodlands.…”

This paper reports the results of dry and wet season systematic terrestrial vertebrate fauna surveys carried out on Blackbraes, a National Park in the Einasleigh Uplands bioregion, North Queensland. It quantifies, for the first time, the biodiversity values of the highest altitude upland area in the Australian tropical savanna. Nine species, including two mammals and seven reptiles, were recorded at the limits of their known range, or in seemingly disjunct populations. Patterns of fauna assemblage in relation to underlying geology and associated habitat variables were investigated and several strong relationships emerged. Temporal patterns in the observed fauna were investigated and 20 species (15 birds, 5 reptiles) were found to be more numerous in different seasons (wet and dry). The avifauna recorded was consistent with much of Australia's tropical savanna, but the reptile and mammal assemblages were distinct, rich and unusual, with exceptionally high abundances, particularly of some arboreal mammals. Blackbraes acts as an upland refuge, but the micro-habitat refuges are unusual in that they are provided by sandy habitats rather than more typical rock refuges.
