... site quality native forest and averaged 15 hectares per koala throughout. The total koala population was estimated by spotlight counts to be 350 to 450 individuals. Variation in scat density (determined by counts in fixed area plots) was best explained by food tree species richness, forest association...

... To identify changes in the dominance of broad groupings of bird species associated with the urbanisation of Sydney, records from the Australian Museum Ornithology Collection database and the Birds Australia Atlas Database were analysed. This historical comparison suggests that parrots, large...

... with litter or logs providing ground-level cover. Rattus fuscipes was the only species to show a difference in abundance between forest types, being 2.6 times more numerous in tall open-forest than open-forest in one study area. Radio-tracking confirmed that the habitat components most strongly associated...

.... At the microhabitat level the variables most frequently associated with abundance of different species of lizard were soil hardness and cover of spinifex Triodia basedowii . Microhabitat associations reflect selection by individuals for local sites that provide specific shelter, foraging or thermoregulation...

... and the criteria used to distinguish between these categories is discussed, although they may not be mutually exclusive. The main concern is that, for most species, we lack information as to the impact which they are having on native species and their associated marine communities. Finally, the difficulty...

..., the species has only recently become widespread in the Brisbane region. We investigated the density and distribution of this and two native house-dwelling geckos in urban, suburban and bushland environments within Brisbane. The spatially clumped insect resources associated with external light sources were...

... s at a beach. Species richness was weakly associated with complexity of the coastline. ...

... in specially designed chambers in the laboratory. Two or three species of Koorrnonga and 17 species of Nousia have so far been identified but are yet to be confirmed by adult association. Factors affecting rearing success have been examined. ...

... Sydney. Native snails are found in all vegetation types in and around Sydney, with some species, such as the Red Triangle Slug Triboniophorus graeffei commonly encountered in suburban gardens. Nearly all species are associated with specific vegetation or habitat types, such as the Cumberland Plain...

... Since European settlement the forests of southeastern Australia have been broken up into disjunct islands by clearing. An important result has been the localized loss of some vertebrate fauna. The remaining mammal fauna is closely associated with forests with a dense understorey. In the long...

... of remnant vegetation or public open space within a 700 m radius of the survey point. This is probably because species that rely on tracts of native vegetation are unable to persist in the urban mosaic of greater Melbourne, while more generalist species are able to cope with the radical changes associated...

... Little attention has been given to nature conservation in the Box-lronbark forests of the inland slopes of southeastern Australia. Past and current forestry practices have led to the widespread removal of mature trees and associated tree hollows. Birds and mammals were surveyed at two sites...

... Computers are increasingly being employed to extend data from surveys of forest fauna across unsurveyed areas, using models relating species occurrence or population density to mapped environmental attributes. This chapter examines current issues and problems associated with this methodology...

... Increasing exploitation of natural systems by humans is the driving force behind global devastation of biodiversity. Extinction risk is however not apportioned evenly across all taxa and specialist species are inherently more vulnerable compared to generalists. World-wide, 16 species...

... a non parametric rank analysis to determine the annual ratio of observations per species versus a surrogate for effort. We also investigated regional patterns in the distribution of the bat fauna using PATN association and classification analysis to identify 6 distinct ‘bat regions’ based on the species...

... for spatial integration. Retrospective research is a valuable tool to address some of the key questions, but longitudinal studies (i.e. over time), are also needed. Successional studies have identified hollow-dependent wildlife species and species that feed from open ground among trees as those that are most...

... ), but also exert indirect negative and indirect positive effects on four species of insular skinks. In the second case study, high levels of activity of domestic house cats ( Felis catus ) in suburban bushland in Sydney are associated with reduced richness of bird species. However, high cat activity also...

... birds nest only on vertical or horizontal dead branches, while others require shrubs or dense ground vegetation. There are significant differences between plant species in the foraging resources available to birds. For example, bark type and the associated arthropod fauna differ between tree species...

... Despite the difficulties associated with conducting research on the Yellow-bellied Glider Petaurus australis , a reasonable body of information has accumulated on its ecology. This information has been collected from several locations throughout the species’ range. Thus, it is timely to present...

..., a nationally more threatened species, would have been less affected by historical deforestation but now faces contemporary clearing of lowland eucalypt associations. It may experience a rapid decline within the urbanising south-east Queensland lowlands unless substantially more remnant vegetation is protected...
