Bryophytes of urban industrial streetscapes in Victoria, Australia

The bryophyte floristics of industrial/commercial streetscapes of urban Victoria and the importance of various substrata to species richness were explored. Species richness was low compared to healthy natural environments. Thirty mosses from 14 families, and six liverworts, each from different families, were identified. Most species occurred at fewer than 30% of sites, showing the patchy nature of their distribution. Only three species occurred at more than half the sites. Markedly higher species richness occurred on soil than on any other substratum. Epiphytes were extremely few. The low bryodiversity of streetscapes, the patchy nature of the bryophytes and the high number of colonists suggest that the streetscapes have not fulfilled their potential in providing connectivity between urban and non-urban areas. Colonists characteristically occur early in the successional sequence of disturbed areas but, as streetscapes are continually disturbed, colonists effectively are climax species for this habitat. Better management of streetscapes to provide more complex habitat is needed to enable colonisation of these areas by bryophyte species that are more representative of our ever-shrinking natural habitats.

Gentrification and cosmopolitan leisure in inner-urban Melbourne, Australia, 1960s-1970s

Studies of gentrification in Australia have typically analysed the phenomenon through the lens of housing and residential change. This article explores how non-residential factors, including the concept of and the everyday practices associated with cosmopolitanism, offer an opportunity to analyse leisure specific to gentrification in Melbourne in the 1960s and 1970s. The article particularly explores leisure based on food and drink cultures located in restaurants, cafés and pubs. Adopting a discursive interdisciplinary approach to studies of the urban past, the article seeks to enhance our historical understanding of the interplay between gentrification and cosmopolitan leisure at a specific place and time in history, by exploring how people perceived themselves and their lifestyles in the midst of urban change.

Representation of multiculturalism in urban green spaces : a review of immigrants' experiences in Australia

Rapid population influx due to migration in Australia has produced diverse cultural landscapes, which become visible in cities as physical forms, settings and symbols produced by different ethnic communities. Scholars have argued that people moving away from the country of their birth, whether this be a necessary migration, labour mobility or voluntary migration, results in a difficult process of resettlement for families and individuals. To provide a cohesive multicultural society for all citizens, it is essential to understand how immigrants perceive their new environments and how they make connections in a new land in the process of cultural renewal. While the policy of ‘multiculturalism’ has had a rocky road since the optimistic 1970s, a drive through many suburbs in Australian cities shows buildings, festivals and communal gatherings of people that express and refer to diverse cultural backgrounds. Urban green spaces, ranging from private home gardens to public parks and botanical gardens, play an important role in the life of immigrants. Besides psychological and the restorative effects of urban green spaces, these spaces are public places that provide opportunities for recreation, social gatherings, and the celebration of collective cultural values and events such as festivals for many communities. This study aims to raise awareness of ethnicity as an important issue in park settings and spaces. It investigates the interrelationship between these cultural practices in the urban park environment, in relation to ethnic and cultural identity and physical settings. The concept of transculturalism – reinventing a new common culture as a result of migration to a new place – can help the analysis of the affects and the perception of urban green spaces. The paper will review different experiences of immigrants in relation to the use and perception of urban green spaces, developing alternative perspectives about the Australian landscapes.

Geographical dimensions of imagined futures: post school participation in education and work in peri-urban and regional Australia

This paper discusses preliminary findings from a sub-set of empirical data collected for a recent NCVER study that explored the geographic dimensions of social exclusion in four locations in Victoria and South Australia with lower than average post school education participation. Set against the policy context of the Bradley Review (2008) and the drive to increase the post-school participation of young people from low socio-economic status neighbourhoods, this qualitative research study, responding to identified gaps in the literature, sought a nuanced understanding of how young people make decisions about their post-school pathways. Drawing on Appadurai’s (2004) concept ‘horizons of aspiration’ the paper explores the aspirations of two young people formed from, and within, their particular rural ‘neighborhoods’. The paper reveals how their post-school education and work choices, imagined futures and conceptions of a ‘good life’, have topographic and gendered influences that are important considerations for policy makers.

Avian assemblages at bird baths: a comparison of urban and rural bird baths in Australia

Private gardens provide habitat and resources for many birds living in human-dominated landscapes. While wild bird feeding is recognised as one of the most popular forms of human-wildlife interaction, almost nothing is known about the use of bird baths. This citizen science initiative explores avian assemblages at bird baths in private gardens in south-eastern Australia and how this differs with respect to levels of urbanisation and bioregion. Overall, 992 citizen scientists collected data over two, four-week survey periods during winter 2014 and summer 2015 (43% participated in both years). Avian assemblages at urban and rural bird baths differed between bioregions with aggressive nectar-eating species influenced the avian assemblages visiting urban bird baths in South Eastern Queensland, NSW North Coast and Sydney Basin while introduced birds contributed to differences in South Western Slopes, Southern Volcanic Plains and Victorian Midlands. Small honeyeaters and other small native birds occurred less often at urban bird baths compared to rural bird baths. Our results suggest that differences between urban versus rural areas, as well as bioregion, significantly influence the composition of avian assemblages visiting bird baths in private gardens. We also demonstrate that citizen science monitoring of fixed survey sites such as bird baths is a useful tool in understanding large-scale patterns in avian assemblages which requires a vast amount of data to be collected across broad areas.

Applying network analysis to the conservation of habitat trees in urban environments: a case study from Brisbane, Australia

In Australia more than 300 vertebrates, including 43 insectivorous bat species, depend on hollows in habitat trees for shelter, with many species using a network of multiple trees as roosts, We used roost-switching data on white-striped freetail bats (Tadarida australis; Microchiroptera: Molossidae) to construct a network representation of day roosts in suburban Brisbane, Australia. Bats were caught from a communal roost tree with a roosting group of several hundred individuals and released with transmitters. Each roost used by the bats represented a node in the network, and the movements of bats between roosts formed the links between nodes. Despite differences in gender and reproductive stages, the bats exhibited the same behavior throughout three radiotelemetry periods and over 500 bat days of radio tracking: each roosted in separate roosts, switched roosts very infrequently, and associated with other bats only at the communal roost This network resembled a scale-free network in which the distribution of the number of links from each roost followed a power law. Despite being spread over a large geographic area (> 200 km(2)), each roost was connected to others by less than three links. One roost (the hub or communal roost) defined the architecture of the network because it had the most links. That the network showed scale-free properties has profound implications for the management of the habitat trees of this roosting group. Scale-free networks provide high tolerance against stochastic events such as random roost removals but are susceptible to the selective removal of hub nodes. Network analysis is a useful tool for understanding the structural organization of habitat tree usage and allows the informed judgment of the relative importance of individual trees and hence the derivation of appropriate management decisions, Conservation planners and managers should emphasize the differential importance of habitat trees and think of them as being analogous to vital service centers in human societies.
