(MR) and Border Ranges (BR) and northern NSW; McGuigan et al. 1998]. The
pattern of genetic divergence was consistent with paleo-climatological modelling
(as for the wet tropics) and also with area relationships suggested by distributions
of rainforest restricted herpetofauna, suggesting the possibility of a general pattern.
However, subsequent (and mostly preliminary) analyses have revealed a more complex picture (Figs. 4 and 5). Phylogeographic analysis of two species of rainforest
restricted skinks from SEQ (Saproscincus rosei and Eulampius murrayi; D.
O'Connor, R. Sadlier and C. Moritz, unpublished data) again revealed strong population subdivision (being stronger in the high altitude species, S. rosei), but the
area relationships were idiosyncratic.
Preliminary data for dry forest species sampled from across SEQ reveal substantial population subdivision (>80% of diversity among populations), except for
Carlia pectoralis, a species of skink located in the drier end of the forest spectrum
for which only a northern isolate is divergent (Fig. 4). Again there are various

Fig. 4. Diagrammatic representations of the distribution of mtDNA phy\ogeographies from
three species of rainforest herpetofauna and one dry forest species from south-east Queensland,
Australia. In each case the trees are simplified from neighbour joining analyses of Kimura 2
parameter distances obtained from sequence analysis of c. 500 bp from 5-10 individuals per
locality. Locations containing monophyletic alleles are grouped into a single branch and
only distances of >1 % are shown. BA, Bania; BR, Border Range; BT, Blackdown Tableland;
