Place-taking and place-making in waterfront renewal, Australia

Waterfront and port zones around the world have long been subject to change, as they have variously been used for trade, waste disposal, leisure and most recently for urban re-imagining, spectacle and lifestyle housing. While such a narrative has been well explored in the urban studies literature, another element of port development – its relation to imperialism and colonisation has not. In the case of colonized countries – such as Australia, but also Canada, the United States and across Africa and Asia – waterfronts were often the entry points of imperial occupancy and key sites for colonial trade and industry. Contestation over how to value and use these sites is integral to their constitution as landscapes, as place taking becomes part of their place making. It will be argued, using case studies drawn from Adelaide and Melbourne in Australia that these sites register a range of culturally-specific imprints connected to the colonisation process. For Indigenous Australians, sea country was indistinguishable from land, but subsequent assessments have seen land demarcated from the ocean, water defiled and obliterated, slums designated but then redeveloped and the Indigenous present rendered benign through its symbolic re-presentation. This post-colonial reading will correlate the divide between land and water with those who have the imperial and class power to define this elemental boundary to add a new dimension to studies of waterfronts.

Climate change and non-Indigenous belonging in postcolonial Australia

The constitution of climate change as an ‘emergency’ invites an appeal to sovereign
power that is troubling in the context of Australia’s colonial history. Climate change is
an unsettling and dispossessing force that, while unprecedented in many ways, can be situated among a series of environmental and social crises that have shaped a discourse of anxious or insecure non-Indigenous belonging in this country. This discourse seeks to render non-Indigenous Australian place as secure and absolute, and understands environmental change as a threat to this goal. This threat appeals to an emergency framing, and in turn to a reassertion, in line with the insights of Agamben, of an exclusive sovereignty that rehearses the foundational dispossessions of colonization. At the same time, climate change is initiating new ways of conceptualizing human relations with place that challenge the value of sovereign status. It enacts realities that refuse a singular emergency and instead generate community from a reorientation of places, times and more-than-human relations. Thought in this way as a creative force that is shaping communities and environments, climate change becomes a source of critical insight for the possibilities of a decolonized future.

Life history and the ecology of stress: how do glucocorticoid hormones influence life-history variation in animals?

Glucocorticoids hormones (GCs) are intuitively important for mediation of age-dependent vertebrate life-history transitions through their effects on ontogeny alongside underpinning variation in life-history traits and trade-offs in vertebrates. These concepts largely derive from the ability of GCs to alter energy allocation, physiology and behaviour that influences key life-history traits involving age-specific life-history transitions, reproduction and survival. Studies across vertebrates have shown that the neuroendocrine stress axis plays a role in the developmental processes that lead up to age-specific early life-history transitions. While environmental sensitivity of the stress axis allows for it to modulate the timing of these transitions within species, little is known as to how variation in stress axis function has been adapted to produce interspecific variation in the timing of life-history transitions. Our assessment of the literature confirms that of previous reviews that there is only equivocal evidence for correlative or direct functional relationships between GCs and variation in reproduction and survival. We conclude that the relationships between GCs and life-history traits are complex and general patterns cannot be easily discerned with current research approaches and experimental designs. We identify several future research directions including: (i) integration of proximate and ultimate measures, including longitudinal studies that measure effects of GCs on more than one life-history trait or in multiple environmental contexts, to test explicit hypotheses about how GCs and life-history variation are related and (ii) the measurement of additional factors that modulate the effects of GCs on life-history traits (e.g. GC receptors and binding protein levels) to better infer neurendocrine stress axis actions. Conceptual models of HPA/I axis actions, such as allostatic load and reactive scope, to some extent explicitly predict the role of GCs in a life-history context, but are descriptive in nature. We propose that GC effects on life-history transitions, survival probabilities and fecundity can be modelled in existing quantitative demographic frameworks to improve our understanding of how GC variation influences life-history evolution and GC-mediated effects on population dynamics Lay Summary Functional Ecology

Evolution and significance of the regeneration reserve heritage landscape of Broken Hill: history, values and significance

In 1991, the National Trust of NSW classified the Regeneration Reserves surrounding the City of Broken Hill as an essential cultural heritage asset of the City of Broken Hill, and in 2015 the City of Broken Hill, including the reserves, were elevated to the National Heritage List under the Commonwealth's Environment Protection and Biodiversity Conservation Act 1999. This tract of land, and its proponents, Albert and Margaret Morris, are recognised as pioneers of arid zone revegetation science in Australia; a point noted in the National Heritage List citation. They created at Broken Hill a unique revegetation ‘greenbelt’ of national ecological, landscape architectural and town planning significance. The Morris’ led the advancement of arid zone botanical investigation and taxonomic inquiry, propagation innovation, and revegetation sciencein the 1920s-40s in Australia and applied this spatially. Their research and practical applications, in crafting the regeneration reserves around Broken Hill, demonstrated the need for landscape harmonisation to occur to reduce erosion and dust damage to human and mining activities alike. This pioneering research and practice informs and underpins much arid zone mine reclamation and revegetation work in Australia today. This paper reviews the historical evolution of this cultural landscape, its integral importance to the cultural heritage and mining history of the City of Broken Hill, and its inclusion as part of the Broken Hill National Heritage List citation.

Menstrual dysfunction and bone health in female athletes

Female athletes are generally considered to be at Iow risk of osteoporosis because of the skeletal loading associated with sports participation. Sites that are exposed to long-term high-impact loading are consistently reported to be higher than the same sites in their sedentary peers. However, weight-bearing exercise does not always ensure that athletes will have high bone-mineral density, as the hormonal environment, dietary factors, and loading history all influence bone-mineral density, In particular, menstrual dysfunction, which can occur with intense training or disordered eating, is a significant risk factor for Iow bone-mineral density. Exercise history before menstrual dysfunction is likely to offer some protection for Iow bone-mineral density, particularly at the hip, Resumption of menses is unlikely to restore bone-mineral density to levels reported in eumenorrheic athletes or even sedentary peers, Athletes at risk of amenorrhea should be identified and their training loads and energy intakes monitored to ensure normal menstrual function, Athletes who remain amenorrheic should be counseled about the possible negative effects of amenorrhea and monitored for bone loss. Early intervention is recommended for amenorrheic athletes with Iow bone-mineral density.

Corners, squares and urban identities: perceptions, attitudes and values

In February 2000, the new Victorian Labor Government announced that they were removing the western shard from Lab Architecture Studio's winning Melbourne Federation Square design. then under construction. The specific 'contested terrain' at the intersection of Flinders Street and Swanston Street Walk. Melbourne, allows the exploration of the politics of place construction over time, through an examination of Young and Jackson's Hotel [1861]. St Paul's Cathedral [1886). Flinders Street Station [1912]. the Westin Hotel [1999) and Federation Square. This site brings together architectural and social history, questions public space and identity, and looks at Melburnian's perceptions, attitudes and values. It further demonstrates that the fragmentation of the professions, and fragmentary histories. lead to the preservation of 'bits' of architecture and the destruction of the urban/landscape context, jeopardizing the Identity of place.

Politicised pagodas and veiled resistance : contested urban space in Burma.

The urban landscapes of Yangon and Mandalay in Burma (Myanmar) exhibit a rich cultural layering and complex blending of urban forms and architectural styles. But while both cities today are shaped by contemporary economic and political realities, they also clearly reflect
their historical origins—Yangon as the British colonial capital and Mandalay as the last seat of the monarchy. Burma’s ancient religious monuments, monarchical and colonial heritage on the one hand, and new religious edifices, international standard hotels, commercial enterprises, new public buildings and satellite towns on the other hand, represent the two poles of the dialectic of tradition and modernity. The landscapes, as symbolic representations, have been appropriated by
the authoritarian military regime, the State Peace and Development Council (SPDC) for nation building purposes. But the urban landscapes are also contested and appropriated in symbolic ways and invested with meanings as sites of resistance and struggle by those in opposition, and
are thus contested sites where the power relations of domination and resistance intersect. The paper illustrates these themes with examples drawn from Yangon and Mandalay.

Responses of freshwater biota to rising salinity levels and implications for saline water management: a review

All of the plants and animals that make up freshwater aquatic communities are affected by salinity. Many taxa possess morphological, physiological and life-history characteristics that provide some capacity for tolerance, acclimatisation or avoidance. These characteristics impart a level of resilience to freshwater communities.     To maintain biodiversity in aquatic systems it is important to manage the rate, timing, pattern, frequency and duration of increases in salinity in terms of lethal and sublethal effects, sensitive life stages, the capacity of freshwater biota to acclimatise to salinity and long-term impacts on community structure.     We have limited understanding of the impacts of saline water management on species interactions, food-web structures and how elevated salinity levels affect the integrity of communities. Little is known about the effect of salinity on complex ecosystem processes involving microbes and microalgae, or the salinity thresholds that prevent semi-aquatic and terrestrial species from using aquatic resources. Compounding effects of salinity and other stressors are also poorly understood.    Our current understanding needs to be reinterpreted in a form that is accessible and useful for water managers. Because of their complexity, many of the remaining knowledge gaps can only be addressed through a multidisciplinary approach carried out in an adaptive management framework, utilising decision-making and ecological risk assessment tools.

Breeding biology, adult survival and territoriality of the white-browed treecreeper (climacteris affinis) in north-west Victoria, Australia

This is the first study to present empirical data describing the social organisation and breeding biology of the White-browed Treecreeper (Climacteris affinis). The species is typical of many small Australian passerines in that it has high annual survival (~80%), small clutches (mean = 1.95 ± 0.05), long breeding seasons (eggs laid August to November) and long incubation (17–18 days) and nestling periods (25–26 days), corrected for body weight. Reproductive effort is modified in response to variation in climatic conditions by adjusting the commencement of breeding and number of clutches laid per season, which is facilitated by an extended breeding season. White-browed Treecreepers occupied relatively large (mean = 8.4 ± 0.8 ha), all-purpose territories throughout the year. However, unlike many group territorial birds, territory size was not related to the number of occupants. The role of food limitation and climatic variability in relation to territory dispersion and life-history traits is explored. Facultative cooperative breeding was confirmed. Cooperative groups were formed through male philopatry, with usually only one, but up to three, male helpers present in a moderate fraction (35%) of breeding units. Thus, all species of Climacteris are now confirmed as facultative cooperatively breeding species, which provides further evidence for the aggregation of cooperative breeders at the generic level in mixed (i.e. cooperative and pair breeders) phylogenetic clades. In C. affinis, males may attain breeding positions through inheritance of their natal territory or by filling vacancies in nearby territories. Females obtained breeding positions by ‘floating’ as non-breeding residents in established territories, waiting for a vacancy to arise.

Methodological and conceptual issues in the search for a relationship between animal body-size distributions and benthic habitat architecture

Benthic ecologists have studied the distribution of animal body sizes because it is a form of ‘taxon-free’ classification that may be a useful metric for describing variation within and between ecological communities. In particular, the idea that the allometry of physiological and life-history traits may control species composition and relative abundances implies a functional link between body-size distributions and communities. The physical structure of aquatic habitats has often been cited as the mechanism by which habitat may determine body-size distributions in communities. However, further progress is hindered by a lack of theoretical clarity regarding the mechanisms that connect body size to the characteristics of ecological communities, leading to methods that may obscure interesting trends in body-size data. This review examines the methodological and conceptual issues hindering progress in the search for a relationship between animal body size and habitat architecture and suggests ways to resolve these issues. Problems are identified with current methods for the measurement of animal body size, the data and measures used to quantify body-size distributions and the methods used to identify patterns therein. Fundamentally, renewed emphasis on the mechanisms by which animal body sizes are influenced by habitat architecture is required to refine methodology and synthesise results from pattern-seeking and mechanistic studies.

The use and misuse of religious language: Zionism and the Palestinians

Every discipline which deals with the land question in Canaan-Palestine- Israel is afflicted by the problem of specialisation. The political scientist and historian usually discuss the issue of land in Israel purely in terms of interethnic and international relations, biblical scholars concentrate on the historical and archaeological question with virtually no reference to ethics, and scholars of human rights usually evade the question of God. What follows is an attempt, through theology and political history, to understand the history of the Israel-Palestine land question in a way which respects the complexity of the question. From a scrutiny of the language used in the Bible to the development of political Zionism from the late 19th century it is possible to see the way in which a secular movement mobilised the figurative language of religion into a literal 'title deed' to the land of Palestine signed by God.

There's no place like home : unhomely moments in three postcolonial picture books

One of the principal strands of postcolonial theory and critical practice is the interrogation of received versions of colonial history. This paper investigates the extent to which three contemporary picture books, Gavin Bishop's The House that Jack Built, John Marsden and Shaun Tan's The Rabbits, and Thomas King and William Kent Monkman's A Coyote Columbus Story, mobilise postcolonial strategies in their representations of place. In particular, it focuses on how postcolonial textuality unsettles and transgresses notions of "homeliness" in narratives involving the displacement of colonised and colonising peoples. As the shifting power relations of colonialism render unhomely what has previously been homely (especially for colonised peoples), so they involve a contrary move in which unhomely spaces are changed into simulacra of lost or abandoned homes. Drawing upon Walter Benjamin's formulation of materialist historiography, Homi Bhabha describes what he terms 'the unhomely moment' as that in which personal and psychic histories intersect with the violent dislocations of colonialism. This paper will argue that such unhomely moments shape the visual and verbal narratives of The House that Jack Built, The Rabbits and A Coyote Columbus Story, all of which deal with the trauma which occurs when cultures previously geographically and psychically distant are brought into close contact with each other. Written to and for children who are citizens of postcolonial cultures, these texts disclose the unease which persists in contemporary societies where colonial histories are rehearsed and revisioned. However, the paper will argue that the three texts position readers in quite different ways; for instance, while the verbal text of The Rabbits constructs an implied author capable of speaking for the colonised and offering readers a very circumscribed subject position, Thomas King's narrative in A Coyote Columbus Story engages in a dialogic playfulness which allows readers to adopt a variety of reading positions. For each text, some key representations of unhomely moments will be considered, and the paper will explore the extent to which they construct forms of temporality which negotiate the space between history and its significances within crosscultural and intercultural formations.
