During the Early Cretaceous, dinosaur communities of the Australian-Antarctic rift system (Eumeralla and Wonthaggi formations) cropping out in Victoria were apparently dominated by a diverse small-bodied ‘basal ornithopod’ fauna. Further north, in Queensland (Winton and Mackunda formations), poorly-represented small-bodied ornithopods coexisted with large-bodied iguanodontians. Our understanding of the ornithopod diversity from the region between the Australian-Antarctic rift and Queensland, represented by Lightning Ridge in central-northern New South Wales (Griman Creek Formation), has been superficial. Here, we re-investigate the ornithopod diversity at Lightning Ridge based on new craniodental remains. Our findings indicate a diverse ornithopod fauna consisting of two-to-three small-bodied non-iguanodontian ornithopods (includingWeewarrasaurus pobenigen. et sp. nov.), at least one indeterminate iguanodontian, and a possible ankylopollexian. These results support those of previous studies that favour a general abundance of small-bodied basal ornithopods in Early to mid-Cretaceous high-latitude localities of southeastern Australia. Although these localities are not necessarily time-equivalent, increasing evidence indicates that Lightning Ridge formed a ‘meeting point’ between the basal ornithopod-dominated localities in Victoria and the sauropod-iguanodontian faunas in Queensland to the north.

New species of Aphelognathus, Belodina, Taoqupognathus, and Yaoxianognathus have been identified in the Late Ordovician Cliefden Caves Limestone Group in central-western New South Wales, Australia. Of the Aphelognathus species, Aphelognathus percivali n. sp. and A. webbyi n. sp. occur in the basal Gleesons Limestone Member and A. packhami n. sp. and A. stevensi n. sp. occur 30 m higher in the Wyoming Limestone Member. It seems likely from the similarity of several of the elements that A. packhami is closely related to A. percivali, and A. stevensi to A. webbyi. Yaoxianognathus wrighti n. sp. occurs in the Gleesons Limestone Member but not in the Wyoming Limestone Member. Belodina confluens, Belodina hillae n. sp., Belodina n. sp., Panderodus gracilis, Taoqupognathus philipi n. sp., and Phragmodus? tunguskaensis occur at both horizons. The conodonts suggest a middle to late Caradocian (mid-Shermanian to mid-Edenian) age for the lowest part of the Cliefden Caves Limestone. The occurrence in southeastern Australia of the forms Taoqupognathus, Yaoxianognathus, and Phragmodus? tunguskaensis suggest affinities to coeval faunas in China and eastern Siberia. The four new species of Aphelognathus are distinct from known species in the Late Ordovician of North America and Europe but they may help characterize a paleobiogeographic region that includes eastern Australia and southeast Asia.

The creek sandpaper fig of southeastern Australia, Ficus coronata Spin, is culturally significant to Australian traditional owners who made use of the leaves to smooth timber and ate the fruit. The species is thought to have a long history on the continent, with some suggesting a Gondwanan origin. However, distributional patterns and overall ecology suggest a recent expansion across suitable habitats. We used landscape genomic techniques and environmental niche modelling to reconstruct its history and explore whether the species underwent a recent and rapid expansion along the east coast of New South Wales. Genomic analysis of 178 specimens collected from 32 populations throughout the species’ New South Wales distribution revealed a lack of genetic diversity and population structure. Some populations at the species’ southern and western range limits displayed unexpected diversity, which appears to be the result of allele surfing. Field work and genetic evidence suggest a Holocene expansion which may have increased since European colonisation. We also present a novel method for detecting allele surfing—MAHF (minor allele at highest frequency).

A grassland wildfire burnt 120,000 ha in the western Riverina of New South Wales and caused exten sive losses of sheep and fencing. The rate of spread of the fire was accurately recorded at 6.4 m s-1 (23 km h-1) as it traversed one property and on the basis of conservative estimates of fuel loads measured later on unburnt patches, a fireline intensity was calculated at around 20,000 kW m-1. This rate of spread is one of the highest recorded for grassland wildfires in southern Australia and represents an important datum point for wildfire behaviour models. Quite reasonable predictions of rate of spread were pro vided by the McArthur Mark 4 fire danger model, how ever, the Mark 5 model seriously underestimated rate of spread for this and two other grassland wildfires.

Five types of woodland and forest in the Bundarra-Barraba region of northern New South Wales were surveyed for Regent Honeyeaters Xanthomyza phrygia and other birds over two years. Regent Honeyeaters were found in 24 of the 93 transects, at a density of 0.09 birds/ha. Most were found in box-ironbark woodland (34% of 62 sites), with single records from box-gum woodland, box-stringybark woodland and dry plateau complex woodland. No Regent Honeyeaters were found in riparian gallery forest during censuses, but they were found breeding there at other times. All habitats contained a high density of birds, compared to other wooded regions in southern Australia, with riparian gallery forest and box-ironbark woodland being particularly rich in species and numbers. These habitats had greater flowering indices, larger trees and more mistletoes than other habitats. Sites used by Regent Honeyeaters supported significantly more birds and bird species than unoccupied sites. The region supports a total of 193 species, four of which are nationally threatened and seven which are threatened in New South Wales. The richness of the bird community in the region is partly because it retains a higher proportion of native vegetation cover (43%) than many other parts of rural Australia. Protection and rehabilitation of box-ironbark woodland and riparian gallery forest is of high priority in a regional conservation plan. However, all habitats in the Bundarra-Barraba region should be protected from clearing and degradation, because they are also used at times by Regent Honeyeaters and support a wide range of bird species. Wise management should retain many sensitive bird species that have disappeared from or declined in other regions of southeastern Australia.

In the field trials of sterile males against the Queensland fruit fly, Dacus tryoni, irradiated pupae of this species were distributed in three towns of western New South Wales in the period September 1962 to March 1965. All these towns and a number of others which served as controls had a previous history of heavy infestation by Dacus tryoni. The success of this method was estimated by comparing the rate of infestation of ripe fruit in treated and untreated towns. The first sign of success came in Manilla in spring (October) 1963 when 51.0% of the eggs deposited in loquats were estimated to be infertile compared with 6.7% in three control towns. However, our production of pupae at this stage was too low to maintain control in Manilla in the summers of 1962-63 and 1963-64. From late April 1963 to late March 1964 most of our production was released in the town of Warren. With a total release in this period of 5.7 x 106 pupae we achieved infestation rates of 2-8% in the summer fruit between early December 1963 and late March 1964, compared with infestation rates of 8-75% in three control towns during the same period. Towards the end of March 1964 the infestation rates began to rise in Warren apparently owing to the immigration of inseminated females along the Macquarie River. An infestation rate of 20% was reached in Warren in April 1964. Between early December 1964 and late March 1965 the rates of infestation in Warren were even more depressed, reaching values of 0 - 7.5% compared with 10-57% in the new control town of Baradine. The total number of pupae released within the town between August 1964 and March 1965 was 12.57 x l06. However, immigrants again brought the infestation up to 10% in April 1965 even though an additional 2.67 x l06 pupae had been distributed along the river for 6 km on either side of the town. In the same period (summer 1964-65) Dacus tryoni was eradicated from Trangie where its numbers had been brought down by trapping out the males with a male lure (Bateman 1966). No infestation was found from October 1964 to April 1965 after the release of 5.33 x l06 pupae between late August 1964 and late March 1965. The rate of infestation in the control town of Gilgandra which had also been treated with cue-lure in the previous summer rose from 0% on October 21, 1964 to 16.2% by April 23,1965. The method could be used to suppress incipient outbreaks of Dacus tryoni in southeastern Australia and even for the eradication of established populations where these are isolated and can be brought low by other means.

Two electrophoretically distinct but morphologically cryptic forms of Antechinus 'stuartii', designated 'northern' and 'southern', occur together at Kioloa on the southern coast of New South Wales. These forms are distinguished by fixed allele differences in three proteins (albumin, glycollate oxidase and mannosephosphate isomerase) and by differences in allele frequencies for transferrin, and are separated by a Nei D of 0.11. The two forms are reproductively isolated in sympatry at Kioloa by asynchrony in the timing of reproduction, and may be considered separate biological species. Northern form populations were identified by screening for albumin and transferrin in seven localities on the central coast of New South Wales north of Kioloa. Southern form populations were identified similarly in 13 localities south of Kioloa and inland along the Great Dividing Range, and at a further locality in southern Victoria. Ovulation occurs at different rates of change of photoperiod in the two species, and may ensure that reproductive isolation is maintained in all potential areas of sympatry. The northern form represents A. stuartii sensu stricto and ranges from Kioloa north into south-eastern Queensland. The southern form is an undescribed species of Antechinus that appears to be widely distributed throughout southern New South Wales and Victoria.
