Surviving urbanisation : maintaining bird species diversity in urban Melbourne

The relationships between vegetation and bird communities within an urban landscape are synthetised, based on a series of studies we conducted. Our studies indicate that streetscape vegetation plays an important role in
influencing urban bird communities, with streetscapes dominated by native plants supporting communities with high native species richness and abundance, while exotic and newly-developed streetscapes support more introduced bird species and fewer native bird species. Native streetscapes can also provide important resources for certain groups of birds, such as nectarivores. Our research has also revealed that urban remnants are likely to support more native bird species if they are larger and if they contain components of riparian vegetation. Vegetation structure and quality does not appear to be as important a driver as remnant size in determining the richness of native bird communities. Introduced birds were shown to occur in remnants at low densities, irrespective of remnant size, when compared to densities found in streetscapes dominated by exotic vegetation. We discuss our results in terms of practical planning and management options to increase and maintain urban avian diversity and conclude by offering suggestions for future fields of research in terms of urban bird communities.

Diet and habitat of the powerful owl (Ninox strenua) living near Melbourne

The diet of Powerful Owls (Ninox strenua) living at Christmas Hills, 35km north-east of Melbourne was examined by analysis of 686 regurgitated pellets collected over two years. An aid was also developed to help identify potential mammalian prey species based on hair and skeletal characteristics. The following features were found to be most useful in distinguishing between the three species of arboreal marsupials - Common Ringtail Possum (Pseudocheirus peregrinus), Common Brushtail Possum (Trichosurus vulpecula) and Sugar Glider (Petaurus breviceps): - Cross-sectional width of primary guard hairs. - The size and shape of the nasal, frontal, parietal and squamosal bones of the skull. - Dentition. The size and shape of the upper incisor, canine and premolar teeth. The size and shape of the lower incisor and premolar teeth. - The size of the humerus. The Sugar Glider has a much smaller humerus than that of the Common Ringtail Possum and the Common Brushtail Possum. In the Common Brushtail Possum the entepicondyle ends in a very sharp point but the Common Ringtail Possum this point is not as sharp. - The Common Ringtail Possum’s femur has a very prominent trochanter which projects further than that in the Common Brushtail Possum. The femur of the Sugar Glider is distinguished by having a very large depression between the condyle and the trochanter. - The Common Brushtail Possum’s scapula has a narrower lower blade (relative to length) than that in the Common Ringtail Possum. The scapula of the Sugar Glider is smaller in size than that of the other two possums.The pelvic girdle Of the Common Brushtail Possum has a much wider ischium than those of the Common Brushtail Possum and the Sugar Glider. The ilium of the Sugar is much narrower and smaller than that of the other two possums Mammalian prey was found in 89%, insects in 13% and birds in 10% of the pellets. Of the mammals, Common Ringtail Possums occurred most frequently in the pellets over the year. There was no seasonal difference in the frequency of occurrence of Common Ringtail Possums and Sugar Gliders in pellets. However, Common Brushtail Possums were more likely to be taken in spring than in the other seasons. More adult Common Ringtail Possums were taken as prey than were other age classes over the year, except in summer when high numbers of young were consumed by the owls. The habitat of the Powerful Owl was examined by ground surveys and spotlight surveys in sixteen sites within the Warrandyte-Kinglake Nature Conservation Link. Four categories of survey sites were chosen with the following features. Category A - Sites with a dense understorey of shrubs and small trees, as well as many old trees (>10/ha) which might be suitable for nest hollows. Category B - Sites which lacked a dense understorey of shrubs and small trees and containing few or no old trees suitable for nest hollows. Category C - Sites with a dense understorey of shrubs and small trees but containing few or no old trees suitable for nest hollows. Category D - Sites which lacked a dense understorey of shrubs and small trees but having old trees (>10/ha) which might be suitable for nest hollows. High prey densities strongly correlated with the presence of hollows at these sites. In the light of the results, management recommendations were made for the future conservation of the Powerful Owls living at Christmas Hills. The following recommendations were particularly important: 1. Cleared or semi - cleared land within the Warrandyte Kinglake Nature Conservation Link be revegetated using indigenous species of eucalypts and waffles in order to provide a contiguous native forest corridor for the movement of possums and gliders between the Yarra River Valley and the Kinglake Plateau. 2. Continued planting of Eucalyptus spp. and Acacia spp. in the forested areas of the Warrandyte-Kinglake Nature Conservation Link. 3. Continued protection of healthy living trees to provide a continuous supply of hollow trees. 4. No falling of dead standing trees for firewood collecting as these can provide nest hollows for prey species of the Powerful Owl.

The development of professional learning and a research culture in a primary school in Melbourne, Australia

This paper outlines the development a/professional/earning and a research culture at Benleigh West Primary School, which is located in a middle class suburb of Melbourne, Victoria. Whilst leadership is widely dispersed at BWPS, as it is in other schools, from students to teachers to the Assistant Principal and Principal, the primary focus in this paper is on the Principal and the ways she has influenced the professional and research culture at the school. Evidence of a change in school climate is presented as are the steps taken to create and foster learning collaborative communities among the staff at BWPS.

Lay meanings and practices of medicinal use in a multicultural context : a qualitative study among Anglo-Celtic and Russian Australians in Melbourne

Describes medicinal use among Anglo-Celtic and Russian Australians. Cultural constructions of medicines are embedded in health beliefs; shaped by experiences with health care within socio-economic and political contexts. Cultural practices of medicinal use are best understood in the context of lay models of rationality and recognition of the conflict existing between the lay and expert models.

Cultural and place identity : a study in Melbourne's western suburbs

This research explored the effect of cultural identity on the character of neighbourhoods in Melbourne's western suburbs. The study revealed that migrant cultural identity is expressed in neighbourhoods with diverse cultural groups although it was found to be shaped by the dominant perception of suburban character.

Analysis of public housing standards in Victoria : 1939-1995

The "housing standard" is a government policy document which defines minimum dwelling standards. This thesis outlines the development of public housing standards in Victoria between 1939 and 1995. The Hotham Housing Estate, North Melbourne, was the case study from which a proposed framework for critical analysis of minimum housing standards was derived.

Community attitudes towards possums in metropolitan Melbourne

Community attitudes toward urban possums in Victoria were examined. 500 questionnaires were sent to a random sample of residents from metropolitan Melbourne (n=103) as well as people who had had experiences with possums (n=340). Negative attitudes toward possums were found to exist in the community and these attitudes were not restricted to those who have had problems with possums. However, the extent of possum problems may be less than commonly believed, as over half of the respondents to newspaper stories calling for people with ‘possum experiences’ reported positive experiences with possums. Increasing media emphasis on positive experiences with possums and school-based education programs are identified as possible strategies for reducing conflicts and learning to live with possums in urban environments.

An artificial intelligence examination of the influence of geological conditions and changes in climate on damage to light structures in Victoria

Damage to light structures in the state of Victoria can be caused by movements of expansive soils. The presentation will present the results of an examination of reports of increasing complaints of house damage in Victoria and particularly in the Melbourne area. The examination analyses the influence of geology and change in climate using Neural Network and Genetic Algorithm approaches and assesses their relative importance in contributing to the cause of the damage.

Portrait of a star : National Gallery of Victoria

Museums are an important segment of the creative industries arena. A "star" art museum in Melbourne, Australia, is the National Gallery of Victoria, whose mission is to illuminate life by collecting and presenting great art. This gallery operates in an increasingly competitive landscape. It is becoming more competitive and is continuously striving to achieve its own ambitions and meet the expectations of multiple stakeholders. The present case study uses a brand orientation lens to evaluate the Gallery in order to address a gap in both the brand orientation and the museum marketing literature. It is crafted from interviews, surveys and internal documents. The case study is an exemplar for other institutions to identify how brand orientation manifests itself within their institution.

The health and well-being of Sudanese young men in Melbourne

The health and well-being needs of young refugee men from Sudan are not adequately addressed by settlement services. To address this, I recommend using Ubuntu and Afrocentric approaches that emphasise dialogue. I have highlighted the problem areas where attention and action is needed for them to realise their full potential.
