Use of habitat by 10 red-necked pademelons was studied by radio-tracking in an area of rain forest that adjoined pasture. They consistently moved at nightfall to pasture, where they grazed until their return to the rain forest shortly before daybreak. The time of movement between habitats was highly predictable and varied seasonally with changes in daylength. Nocturnal and diurnal range areas are described within the total area occupied by each individual. They rarely moved from the forest edge more than 70 m onto pasture or 500 m into rain forest. Animals were not nocturnal and travelled widely through the rain forest by day, seeking food and sites for basking. The nocturnal and diurnal partitioning of habitat is seen as a strategy for exploiting the rich food resource of pasture while maximizing the probability of avoiding predators.

The behaviour was observed, in captivity, of the bilby Macrotis lagotis, a fossorial bandicoot of central Australia. Most of the observations were made at night, but some were of below-ground behaviour during the daylight hours. Bilbies proved to be relatively passive in comparison with other bandicoots, and a rigid dominance hierarchy amongst males was maintained without destructive fighting. Dominant males chased subordinate males out of and away from burrows and the alpha male maintained priority of access to all the well used burrows in the enclosure. Males scent-marked around burrows; the dominant male usually marked over scents left by other bilbies. Males shared burrows freely with females, and copulation appears to take place down burrows. Information is also given on female-female and mother-young behaviour, and some suggestions are made concerning the social structure of wild bilbies. Activity cycles, feeding behaviour, etc. are described.

Blandfordia nobilis Smith (Liliaceae) is a small herbaceous monocotyledon that resprouts from a rhizomatous corm after fire. The complex pattern of flowering shown in the five years following a fire in January 1987 was investigated for five populations near Sydney. This pattern was then related to concurrent changes in soil chemistry. Most (60%) plants flowered in the first post-fire flowering season (November-January), but this dropped to fewer than 20% of the plants flowering by the third or fourth season. Most plants flowered only once, but almost all plants did flower. Consequently, 35% of the flowering events were by plants that flowered only within the first year. Flowering in the first season produced more flowers per plant in that season, and was also correlated with increased chance that a plant would flower again. Repeat flowering produced fewer flowers per plant in the subsequent seasons, but multiple flowering did increase the total number of flowers produced per plant. This form of pulse flowering and short secondary juvenile period after fire seems to be typical of resprouting monocotyledons in Australia, but is much less common among resprouting dicotyledons. The pulse of flowering appears to be closely associated with changes in the soil chemistry during the post-fire period. Many of the soil attributes measured show either a characteristic decrease or increase during the 3-4 years following the fire, with a subsequent reversal in the trend. The plants thus flower prolifically during these changing soil conditions, but almost cease flowering when these changes are reversed, thereby taking advantage of soil conditions that are not available throughout most of the inter-fire period.

Ambuchanania leucobryoides is a moss listed as rare under the Tasmanian Threatened Species Protection Act 1995. It is endemic to Tasmania and is monotypic at the genus and family levels. It is sister group to the widespread and speciose genus Sphagnum. In 2008, a survey funded by the Tasmanian Wilderness World Heritage Area Program (Department of Primary Industries and Water) established the exact location of the A. leucobryoides type locality and extended the known range of the moss. The moss is now known from three locations in southwest Tasmania and has a range of 127 2 km. It occurs in sandy washes or "daisy pans" derived from Precambrian quartzite.

The taxa in Blandfordia are often difficult to separate morphologically. A multivariate morphometric analysis of data from both herbarium and field samples suggests that the genus consists of at least four polythetically distinct taxa, corresponding to the traditional concepts of B. cunninghamii Lindley, B. grandifora R.Br., B. nobilis Smith, and B. punicea (Labill.) Sweet. The morphological boundaries between most of these species are arbitrary but are closely related to a number of environmental variables. Due to large intra-population variability, discrimination between these taxa is possible only on the basis of a combination of attributes, notably leaf width and margin sculpturing, and flower length and diameter. The morphological distinction between B. punicea and the other species is clear and seems to be maintained by its geographical isolation. The distinction between B. grandiflora and B. cunninghamii is based on vegetative rather than floral attributes and is made difficult by phenotypic response of B. cunninghamii plants to light intensity. Gene flow between these two species appears to be restricted by their separate habitats. The distinction between B. grandiflora and B. nobilis is based on floral rather than vegetative attributes and is related to latitude with the species being more distinct in the area of parapatry than in the area of allopatry. In the small area of sympatry there appears to be introgression of B. nobilis attributes into B. grandiflora populations.
