“…We interpret this as selection for forage-rich microhabitats at a time of lowered predation risk. Many herbivorous mammals move between sheltered diurnal and more open forage-rich nocturnal locations (Johnson 1980;Ager et al 2003;Nielsen et al 2004;le Mar and McArthur 2005;Moe et al 2007), a temporal transition that probably reduces the conflict between food acquisition and predator avoidance (Lima and Dill 1990). Our fine-scale data indicate similar behaviour by the wallabies in our sample, who may have been responding to potential predators such as red foxes (Vulpes vulpes) or wedge tailed eagles (Aquila audax), both of which occurred at the study site.…”

“…Habitat selection may also differ during the 24-h cycle (Beyer and Haufler 1994), reflecting changing influences throughout this period. Many herbivorous mammals select sheltered diurnal resting sites and forage-rich nocturnal habitats (Johnson 1980;Fisher 2000;Ager et al 2003;Nielsen et al 2004;le Mar and McArthur 2005;Moe et al 2007), a likely response to the conflicting demands of food acquisition and predator avoidance (Lima and Dill 1990).…”

Fine-scale habitat selection by adult female swamp wallabies (Wallabia bicolor)

Animals typically use habitat in a non-random way, but the factors influencing habitat selection may change throughout the 24-h cycle. In this study, we quantified resources at used and available locations to test two predictions about the fine-scale habitat selection of seven adult female swamp wallabies (Wallabia bicolor). We predicted that selection would be (i) non-random and (ii) differ between diurnal and nocturnal periods with respect to both food and shelter. Variables quantifying food abundance and lateral cover were recorded at 56 diurnal, 17 nocturnal and 143 randomly selected available locations. Logistic regression indicated that diurnal habitat selection was positively correlated with lateral cover, and the cover of trees, shrubs and forbs, whereas nocturnal selection was positively correlated with forb cover only. Diurnal locations had more lateral cover than nocturnal locations. The data were consistent with our first prediction, but only partially supported our second. At a fine scale, diurnal habitat selection was influenced by the co-availability of shelter and food resources, whereas nocturnal selection was influenced by food availability only, indicating that factors influencing habitat selection changed throughout the 24-h cycle.

“…Edge‐oriented behaviors are often attributed to the increased richness of resources found on vegetation edges (Odum, Odum, & Andrews, ), however within our study site, boundaries between landscape features are sharp and we conclude that wallabies were attracted by the different resources (shelter vs. food) provided within each landscape feature, but avoided pasture during the day due to higher risk. Our findings suggest that the high selection of cover during the day and an increase in selection of farmland during the night are likely due to swamp wallabies optimizing the trade‐off between the selection of another rich food source, such as pasture (Johnson, ) and risk and stress avoidance. Such temporal transition is shown by many macropods (Le Mar & McArthur, ; Swan et al, ) and is often explained as behavioral responses to potential predators.…”

Animals access resources such as food and shelter, and acquiring these resources has varying risks and benefits, depending on the suitability of the landscape. Some animals change their patterns of resource selection in space and time to optimize the trade‐off between risks and benefits. We examine the circadian variation in resource selection of swamp wallabies ( Wallabia bicolor ) within a human‐modified landscape, an environment of varying suitability. We used GPS data from 48 swamp wallabies to compare the use of landscape features such as woodland and scrub, housing estates, farmland, coastal areas, wetlands, waterbodies, and roads to their availability using generalized linear mixed models. We investigated which features were selected by wallabies and determined whether the distance to different landscape features changed, depending on the time of the day. During the day, wallabies were more likely to be found within or near natural landscape features such as woodlands and scrub, wetlands, and coastal vegetation, while avoiding landscape features that may be perceived as more risky (roads, housing, waterbodies, and farmland), but those features were selected more at night. Finally, we mapped our results to predict habitat suitability for swamp wallabies in human‐modified landscapes. We showed that wallabies living in a human‐modified landscape selected different landscape features during day or night. Changing circadian patterns of resource selection might enhance the persistence of species in landscapes where resources are fragmented and disturbed.

“…However, the optimal spatial scale of burnt patches and the appropriate frequency of burning to achieve favourable habitat for mammals like Lagorchestes hirsutus are not known and requires investigation. There is some evidence that small mammals in heathlands in temperate Australia and macropods in rain forests on the eastern seaboard of Australia may also have benefited from Aboriginal burning (Stoddart & Braithwaite, 1979 ;Johnson, 1980 ;Vernes, Marsh & Winter, 1995). Much more research into the relationship between mammals and the age of vegetation since the last fire remains to be carried out throughout Australia (Fox & McKay, 1981).…”

The impact of Aboriginal landscape burning on the Australian biota

1998

One of the most complex and contentious issues in Australian ecology concerns the environmental impact of Aboriginal landscape burning. This issue is not only important for the development of a comprehensive understanding of the dynamics and evolution of the Australian biota, but is central to the formulation of appropriate strategies for the conservation of the nation's biodiversity. Ethnographic evidence leaves little doubt that Aboriginal burning played a central role in the maintenance of the landscapes subsequently colonized by Europeans. Both 19th century European colonists and anthropologists in the 20th century documented the indispensability of fire as a tool in traditional Aboriginal economies, which have aptly been described as ‘fire‐stick farming’. Aborigines used fire to achieve short‐term outcomes such as providing favourable habitats for herbivores or increasing the local abundance of food plants, but it is not clear whether or not Aborigines had a predictive ecological knowledge of the long‐term consequences of their use of fire. A large body of ecological evidence suggests that Aboriginal burning resulted in substantial changes in the geographic range and demographic structure of many vegetation types. Aboriginal burning was important in creating habitat mosaics that favoured the abundance of some mammal species and in the maintenance of infrequently burnt habitats upon which the survival of specialized fauna depends. Aboriginal fire regimes were probably critical for the maintenance of at least one species of tree (Callitris intratropica) in the monsoon tropics. The question of the original impact of humans on the Australian environment is fundamentally speculative because of vague, disputed time frames proposed for the waves of colonization and shifting settlement patterns of Aborigines in the late Quaternary period. There is an inherent circular argument concerning the cause and effect of climate change, vegetation change, and burning through the late Quaternary. Charcoal and pollen evidence from long sedimentary cores is ambiguous and cannot be used to demonstrate unequivocally the initial impact of Aboriginal people on the landscapes of Pleistocene Australia. The sparse available evidence does not support the hypotheses that Aboriginal burning was primarily responsible for the extinction of Pleistocene megafauna; was critical for the maintenance of habitats of small mammals that have become extinct following European colonization; initiated widespread accelerated soil erosion rates in either the Pleistocene or Holocene; or forced the evolutionary diversification of the Australian biota. Burning may have caused the extinction of some fire‐sensitive species of plants and animals dependent upon infrequently burnt habitats, and it must have maintained structurally open vegetation such as grasslands and also extended the range of fire‐adapted species, such as Eucalyptus, into environments climatically suitable for rain forest. Palaeoecological research concerning prior impacts of Aborigines must ...
