The influence of time since fire and distance from fire boundary on the distribution and abundance of arboreal marsupials in Eucalyptus regnans-dominated forest in the Central Highlands of Victoria

The impact of time since fire after two consecutive wildfires 44 years apart (1939 and 1983) within the same area, and the distance from the fire boundary «100 m or 500-2000 m), were investigated in relation to the distribution and abundance of arboreal marsupials in 1994. Arboreal marsupials were censused by stagwatching and spotlighting in two relatively young age classes of mountain ash (Eucalyptus regnans) dominated forest in the Central Highlands of Victoria. Five species of arboreal marsupial were detected, but only three were detected in sufficient numbers to determine habitat preferences. Petauroides volans (greater glider) was statistically more abundant in 1939 regrowth forests, while Trichosurus caninus (mountain brushtail possum) showed no significant preference for either age class of forest. All but one record of Gymnobelideus leadbeateri (Leadbeater's possum) came from young forest, though the effect of age-class was not statistically significant. Distance from fire boundary explained little or no variation in mammal distribution or abundance. While the actual number of hollow-bearing trees was similar in both age classes of forest, the long-term lifespan of hollow-bearing trees in more recently burnt forest is predicted to be lower than in unburnt or not recently burnt forest. Post-fire salvage logging following the 1983 wildfires appears to have reduced the number of hollow-bearing trees at sites burnt in 1983.

Habitat use and distribution of the beautiful firetail (stagonopleura bella) in foothill forests of the Victorian highlands, Australia

The Beautiful Firetail (Stagonopleura bella) is an uncommon, granivorous finch from coastal south-eastern Australia, with a distribution extending from mid-coastal New South Wales to south-eastern South Australia, including Tasmania. This paper presents a quantitative assessment of habitat use by the Beautiful Firetail based on data collected from 30 paired riparian and non-riparian sites in the foothill forests of the Victorian Highlands, Australia. The Beautiful Firetail occurred in two of the three forest blocks surveyed and was found almost exclusively at riparian sites. The Beautiful Firetail was most likely to occur at riparian sites on the coastal fall of the ranges at sites with high sedge cover and low cover of shrubs and bare ground. The species occurred at low densities (0.10–0.19 individuals ha^–1) throughout the year. Records from the Atlas of Victorian Wildlife were used to describe the distribution of Beautiful Firetails in Victoria. Notable observations inland of the Great Dividing Range were recorded during the present study. Further study is required to understand the ecological requirements of the Beautiful Firetail throughout its range.

Epiphytic bryophytes of Dicksonia antarctica Labill. from selected pockets of cool temperate rainforest, Central Highlands, Victoria

Epiphytic bryophytes of the Soft Tree-fern Dicksonia antarctica Labill. were examined in four Cool Temperate Rainforest pockets of the Central Highlands of Victoria. Thirty-two species, 17 mosses and 15 liverworts, were noted. There was no distinction in species assemblage between the north and south side of tree-ferns although bryophytes occurred on the south side of more tree-ferns than they did on the north side.

History of contact and change in the Goroka Valley, Central Highlands of New Guinea, 1934-1949

The thesis traces the interaction of the Goroka Valley people with European and coastal New Guinean intruders during the pacification stage of contact and change. In this 15 year period the people moved from a traditional subsistence culture to the threshold of a modern, European-influenced technological society. The contact experiences of the inhabitants of the Valley and the outsiders who influenced them are examined, using both oral and documentary sources. A central theme of this study is the attempts by Europeans and their coastal New Guinean collaborators to achieve the pacification of a people for whom warfare has been described as 'the dominant orientation'. The newcomers saw pacification as being inextricably linked with social, economic and religious transformation, and consequently it was pursued by patrol officers, missionaries and soldiers alike. Following an introductory chapter outlining the pre-contact and early-contact history of the Goroka Valley people, there is a discussion of the causes of tribal fighting in Highlands communities and two case studies of violent events which, although occurring beyond the Goroka Valley, had important consequences for those who lived within its bounds. The focus then shifts to the first permanent settlement of the agents of change -initially these were coastal New Guinean evangelists and policemen - and their impact on the local people. A period of consolidation is then described, as both government and missions established a permanent 'European presence in the Valley'. This period was characterised by vigorous pacification coupled with the introduction of innovations in health and education, agriculture, technology, law and religion. The gradual transformation of Goroka Valley society as a result of the people's interaction with the newcomers was abruptly accelerated in 1943, when many hundreds of Allied soldiers occupied the Valley in anticipation of a threatened Japanese invasion. Village life was disrupted as men were conscripted as carriers and labourers and whole communities were obliged to grow food to assist the Allied war effort. Those living close to military airfields-and camps were subject to Japanese aerial attacks and the entire population was exposed to an epidemic of bacillary dysentery introduced by the combatants. However the War also brought some positive effects, including paradoxically, the almost total cessation of tribal fighting, the construction of an ail-weather airstrip at Goroka which ensured its future as a town and administrative and commercial centre, and the compulsory growing of vegetables, coffee, etc, which laid the foundations for a cash economy and material prosperity. The final chapter examines the aftermath of military occupation, the return of civil administration and the implementation of social and economic policies which brought the Goroka Valley people into the rapid-development phase of contact. By 1949 Gorokans were ready to channel their aggressive energies into commercial competitiveness and adopt a cash-crop economy, to accept the European rule of law, to take advantage of Western innovations in medicine, education, transport and communications, to seek employment opportunities at home and in other parts of the country and to modify their primal world view with European religious and secular values. A Stone Age people was in process of being transformed into a modern society.

Origins of agriculture at Kuk Swamp in the highlands of New Guinea

Multidisciplinary investigations at Kuk Swamp in the Highlands of Papua New Guinea show that agriculture arose independently in New Guinea by at least 6950 to 6440 calibrated years before the present (cal yr B.P.). Plant exploitation and some cultivation occurred on the wetland margin at 10,220 to 9910 cal yr B.P. (phase 1), mounding cultivation began by 6950 to 6440 cal yr B.P. (phase 2), and ditched cultivation began by 4350 to 3980 cal yr B.P. (phase 3). Clearance of lower montane rainforests began in the early Holocene, with modification to grassland at 6950 to 6440 cal yr B.P. Taro (Colocasia esculenta) was utilized in the early Holocene, and bananas (Musa spp.) were intensively cultivated by at least 6950 to 6440 cal yr B.P.

Predation on a blotched bluetongue lizard (Tiliqua nigrolutea) by a highlands copperhead (Austrelaps ramsayi) in the Blue Mountains, Australia

This note documents a predation event on a juvenile Blotched Bluetongue Lizard (Tiliqua nigrolutea) by a Highlands Copperhead (Austrelaps ramsayi) in the Blue Mountains, Australia.  The diet of elapid snakes in the genus Austrelaps consists mainly of frogs and small skinks. Adults of the larger Tiliqua species may be too large for Austrelaps species to consume, and juveniles of these larger Tiliqua are possibly approaching the larger end of consumable prey items for Austrelaps.

The role of Riparian habitats in forest mosaics in promoting Avifauna at the landscape scale

The importance of riparian habitats to bird communities is well documented internationally, however the value of these habitats in largely intact landscapes is less well understood, particularly in Australia. Thirty paired riparian and adjacent non-riparian sites were selected within extensive forest mosaics of the Victorian Central Highlands and were surveyed over a two year period. Bird assemblages occurring within riparian habitats supported a significantly greater richness, abundance and diversity of species. These assemblages were also found to have species compositions significantly different from those occurring at adjacent non-riparian sites separated by a distance of approximately 750 m. Differences were attributed to a suite of distinctive species and significant contrasts in the densities of a range of species that occur in both habitat types. At the landscape level, there was a strong patterning of the avifauna centred on riparian habitats. Bird assemblages typically comprised four distinct suites of species: 1. species widespread in forests and woodlands of southeastern Australia; 2. riparian associated species (wet forest intruders); 3. riparian selective species, and; 4. riparian avoiding species. Both physiognomic and floristic differences between riparian and adjacent non-riparian habitats appear to drive responses in the structure of bird communities. There exists a distinctiveness and variability among the range of vegetation types and associated bird assemblages occurring throughout the forest matrix, including in riparian habitats. The occurrence of complimentary bird assemblages throughout the landscape mosaic highlights the importance of whole landscape planning for avifauna conservation.

Are rural health professionals also social entrepreneurs?

Social entrepreneurs formally or informally generate community associations and networking that produces social outcomes. Social entrepreneurship is a relatively new and poorly understood concept. Policy promotes generating community activity, particularly in rural areas, for health and social benefits and ‘community resilience’. Rural health professionals might be well placed to generate community activity due to their status and networks. This exploratory study, conducted in rural Tasmania and the Highlands and Islands of Scotland considered whether rural health professionals act as social entrepreneurs. We investigated activities generated and processes of production. Thirty-eight interviews were conducted with general practitioners, community nurses, primary healthcare managers and allied health professionals living and working rurally. Interviewees were self-selecting responders to an invitation for rural health professionals who were ‘formally or informally generating community associations or networking that produced social outcomes’. We found that rural health professionals initiated many community activities with social outcomes, most related to health. Their identification of opportunities related to knowledge of health needs and examples of initiatives seen elsewhere. Health professionals described ready access to useful people and financial resources. In building activities, health professionals could simultaneously utilise skills and knowledge from professional, community member and personal dimensions. Outcomes included social and health benefits, personal ‘buzz’ and community capacity. Health professionals' actions could be described as social entrepreneurship: identifying opportunities, utilising resources and making ‘deals’. They also align with community development. Health professionals use contextual knowledge to envisage and grow activities, indicating that, as social entrepreneurs, they do not explicitly choose a social mission, rather they act within their known world-view. Policymakers could consider ways to engage rural health professionals as social entrepreneurs, in helping to produce resilient communities.

Ecological value of riparian zones to birds in forest landscapes

Riparian zones are a characteristic component of many landscapes throughout the world and increasingly are valued as key areas for biodiversity conservation. Their importance for bird communities has been well recognised in semi-arid environments and in modified landscapes where there is a marked contrast between riparian and adjacent non-riparian vegetation. The value of riparian zones in largely intact landscapes with continuous vegetation cover is less well understood. This research examined the importance of riparian habitats for avifauna conservation by investigating the ecological interactions contributing to the pattern of bird assemblages in riparian and adjacent non-riparian habitats. Specifically, the focus is on the bird assemblages of riparian zones and those of adjacent non-riparian vegetation types and the influence that associated differences in resource availabilities, habitat structure and conditions have on observed patterns. This study was conducted in the foothill forests of the Victorian Highlands, south-east Australia. Mixed-species eucalypt (genus Eucalyptus) forests dominate the vegetation of this region. Site selection was based on the occurrence of suitable riparian habitat interspersed within extensive, relatively undisturbed (i.e. no recent timber harvesting or fire events) forest mosaics. A series of 30 paired riparian and non-riparian sites were established among six stream systems in three forest areas (Bunyip State Park, Kinglake National Park and Marysville State Forest). Riparian sites were positioned alongside the stream and the non-riparian partner site was positioned on a facing slope at a distance of approximately 750 m. Bird surveys were carried out during 29 visits to each site between July 2001 and December 2002. Riparian sites were floristically distinct from non-riparian sites and had a more complex vegetation structure, including a mid-storey tree layer mostly absent from non-riparian sites, extensive fine litter and coarse woody debris, and dense ground-layer vegetation (e.g. sedges and ground ferns). The characteristic features of non-riparian habitats included a relatively dense canopy cover, a ground layer dominated by grasses and fine litter, and a high density of canopy-forming trees in the smaller size-classes. Riparian zones supported a significantly greater species richness, abundance and diversity of birds when compared to non-riparian habitats. The composition of bird assemblages differed significantly between riparian and non-riparian habitats, with riparian assemblages displaying a higher level of similarity among sites. The strongest contributors to observed dissimilarities between habitat types included species that occurred exclusively in either habitat type or species with large contrasts in abundance between habitat types. Much of the avifauna (36%) of the study area is composed of species that are common and widespread in south-east Australia (i.e. forest generalists). Riparian habitats were characterised by a suite of species more typical of wetter forest types in south-east Australia and many of these species had a restricted distribution in the forest mosaic. Some species (7%) occurred exclusively in riparian habitats (i.e. riparian selective species) while others (43%) were strongly linked to these habitats (i.e. riparian associated species). A smaller proportion of species occurred exclusively (2%) in non-riparian habitats (i.e. non-riparian selective species) or were strongly linked to these habitats (10%; i.e. non-riparian associated species). To examine the seasonal dynamics of assemblages, the variation through time in species richness, abundance and composition was compared between riparian and non-riparian sites. Riparian assemblages supported greater richness and abundance, and displayed less variation in these parameters, than non-riparian assemblages at all times. The species composition of riparian assemblages was distinct from non-riparian assemblages throughout the annual cycle. An influx of seasonal migrants elevated species richness and abundance in the forest landscape during spring and summer. The large-scale movement pattern (e.g. coastal migrant, inland migrant) adopted by migrating species was associated with their preference for riparian or non-riparian habitats in the landscape. Species which migrate north-south along the east coast of mainland Australia (i.e. coastal migrants) used riparian zones disproportionately; eight of eleven species were riparian associated species. Species which migrate north-south through inland Australia (i.e. inland migrants) were mostly associated with non-riparian habitats. The significant differences in the dynamics of community structure between riparian and non-riparian assemblages shows that there is a disproportionate use of riparian zones across the landscape and that they provide higher quality habitat for birds throughout the annual cycle. To examine the ecological mechanisms by which riparian assemblages are richer and support more individual birds, the number of ecological groups (foraging, nest-type and body mass groups) represented, and the species richness of these groups, was compared between riparian and non-riparian assemblages. The structurally complex vegetation and distinctive habitat features (e.g. aquatic environments, damp sheltered litter) provided in the riparian zone, resulted in the consistent addition of ecological groups to riparian assemblages (e.g. sheltered ground – invertebrates foraging group) compared with non-riparian assemblages. Greater species richness was accommodated in most foraging, nest-type and body mass groups in riparian than non-riparian assemblages. Riparian zones facilitated greater richness within ecological groups by providing conditions (i.e. more types of resources and greater abundance of resources) that promoted ecological segregation between ecologically similar species. For a set of commonly observed species, significant differences in their use of structural features, substrates and heights were registered between riparian and non-riparian habitats. The availability and dynamics of resources in riparian and non-riparian habitats were examined to determine if there is differential availability of particular resources, or in their temporal availability, throughout the annual cycle. Riparian zones supported more abundant and temporally reliable eucalypt flowering (i.e. nectar) than non-riparian habitats throughout the annual cycle. Riparian zones also supported an extensive loose bark resource (an important microhabitat for invertebrates) including more peeling bark and hanging bark throughout the year than at non-riparian sites. The productivity of eucalypts differed between habitat types, being higher in riparian zones at most times for all eucalypts combined, and for some species (e.g. Narrow-leaved Peppermint Eucalyptus radiata). Non-riparian habitats provided an abundant nectar resource (i.e. shrub flowering) at particular periods in the annual cycle. Birds showed clear relationships with the availability of specific food (i.e. nectar) and foraging resources (i.e. loose bark). The demonstration of a greater abundance of resources and higher primary productivity in riparian zones is consistent with the hypothesis that these linear strips that occupy only a small proportion of the landscape have a disproportionately high value for birds. Riparian zones in continuous eucalypt forest provide high quality habitats that contribute to the diversity of habitats and resources available to birds in the forest mosaic, with positive benefits for the landscape-level species pool. Despite riparian and non-riparian habitat supporting distinct assemblages of birds, strong linkages are maintained along the riparian-upslope gradient. Clearly, the maintenance of diverse and sustainable assemblages of birds in forest landscapes depends on complementary management of both riparian and non-riparian vegetation.
