Population Strategy

In adjacent areas in north-eastern New South Wales, T. vulpecula occurs in the open forest and woodland and T. caninus occurs in the closed and tall open forest; both species are found in the pine plantation. T. vulpecula has a single breeding season in autumn when all females 1 y old and older reproduce. The young become independent around 175 days old and disperse at up to 2 y old. Mortality is low (15%) among dependent young but considerably higher among independent dispersing individuals. T. caninus also has a single autumn breeding season. The young become independent around 240 days old but disperse after 18-26 months, females moving before males. Mortality is high (56%) among dependent young but less so among subadults. An adult sex ratio of parity is the result of a higher survival among subadult males than females offsetting the reverse in adults. Some 2-y-old and all 3-y-old females reproduce but a few older females fail to breed in certain years. There is evidence that the high mortality of dependent young and failure of older females to breed is associated with offspring of previous years remaining in the population. Adult males and females appear to form a pair-bond. Population parameters of T. vulpecula described from other areas show considerable variation; this flexibility in population strategy explains the species' success in occupying a diversity of habitats and rapidly colonizing new areas.

Surveys were conducted for the Giant Burrowing Frog Heleioporus australiacus within 50 km of Nowra, on the south coast of New South Wales using a variety of methods. Thirty-eight 250 m transects were surveyed at night for 30 min each and 0–12 adult frogs were detected during these searches. Additional diurnal searches for tadpoles proved to be the most efficient method to detect the species and locate breeding sites. Of 102 sites surveyed, fragmented populations were found at 27 by the presence of tadpoles and adult frogs. The vegetation at these sites was woodland and open forest with a dense shrublayer of heath, but was often ecotonal. Forty-six percent of the sites were within 100 m of cliff edges/waterfalls. The lithology of sites where the frog was found varied from Hawkesbury, Nowra and Snapper Point sandstones. The exception was a population south of Ulladulla that occurs on undifferentiated sediments, but at that site exposed sandstone and a sandy overlay was present. The location of tadpoles indicated that adults were highly selective of the section of drainage line used for breeding. Often these sites consisted of a few small pools in non-perennial creeks. Breeding behaviour was associated with late summer and autumn rain, but in some sites reproduction did not occur annually. Based on distribution and habitat preference, the region has five discrete populations. Urban development has fragmented populations.

Microlaena Stipoides

Dominance of herbaceous species was examined in relation to tree cover in lightly grazed stringybark Eucalyptus laevopinea open-forest recovering from ringbarking and logging on the Northern Tablelands of New South Wales (NSW). The dominant herb was recorded in 121 quadrats (0.25 m2) in 24 plots (10 × 10) stratified by tree cover (beneath trees, away from trees, and amongst small sapling stands). Aristida ramosa dominated the grassy understorey in interspaces, whereas Microlaena stipoides was the most frequent dominant beneath and near tree cover. Poa sieberiana was also more abundant beneath trees. Dominance varied in sapling stands between these three species, suggesting that tree invasion triggers herbaceous succession away from A. ramosa towards M. stipoides and P. sieberiana. It is suggested that year-long green, shade-tolerant grasses such as M. stipoides are better suited to the shaded, fertile, frost-protected environment beneath mature tree canopies, and deep-rooted, summer-active grasses such as A. ramosa are favoured away from the canopies and root zones of trees.

Autumn And Winter

Scats of long-nosed bandicoots (Perameles nasuta) from north-eastern New South Wales were examined for seasonal occurrence of fungi. Fungus was detected in bandicoot diets in all seasons, but samples from autumn and winter were more likely to contain fungi, and more taxa were consumed in these seasons, compared with spring and summer. Individual scat samples also contained more spore types in autumn and winter than in spring and summer. My results support other work in temperate south-eastern Australia that indicate an autumn and winter peak in fungal availability, and a stronger focus on fungal consumption by mammals at this time of year.
