Spatial and temporal drivers of small mammal distributions in a semi-arid environment : the role of rainfall, vegetation and life-history

A key task in ecology is to understand the drivers of animal distributions. In arid and semi-arid environments, this is challenging because animal populations show considerable spatial and temporal variation. An effective approach in such systems is to examine both broad-scale and long-term data. We used this approach to investigate the distribution of small mammal species in semi-arid ‘mallee’ vegetation in south-eastern Australia. First, we examined broad-scale data collected at 280 sites across the Murray Mallee region. We used generalized additive mixed models (GAMMs) to examine four hypotheses concerning factors that influence the distribution of individual mammal species at this scale: vegetation structure, floristic diversity, topography and recent rainfall. Second, we used long-term data from a single conservation reserve (surveyed from 1997 to 2012) to examine small mammal responses to rainfall over a period spanning a broad range of climatic conditions, including record high rainfall in 2011. Small mammal distributions were strongly associated with vegetation structure and rainfall patterns, but the relative importance of these drivers was species-specific. The distribution of the mallee ningaui Ningaui yvonneae, for example, was largely determined by the cover of hummock grass; whereas the occurrence of the western pygmy possum Cercartetus concinnus was most strongly associated with above-average rainfall. Further, the combination of both broad-scale and long-term data provided valuable insights. Bolam's mouse Pseudomys bolami was uncommon during the broad-scale survey, but long-term surveys showed that it responds positively to above-average rainfall. Conceptual models developed for small mammals in temperate and central arid Australia, respectively, were not, on their own, adequate to account for the distributional patterns of species in this semi-arid ecosystem. Species-specific variation in the relative importance of different drivers was more effectively explained by qualitative differences in life-history attributes among species.

Exploration strategies map along fast-slow metabolic and life-history continua in muroid rodents

1Personality is highly relevant to ecology and the evolution of fast–slow metabolic and life-history strategies. One of the most important personality traits is exploratory behaviour, usually measured on an animal introduced to a novel environment (e.g. open-field test).2Here, we use a unique comparative dataset on open-field exploratory behaviour of muroid rodents to test a key assumption of a recent evolutionary model, i.e. that exploration thoroughness is positively correlated to age at first reproduction (AFR). We then examine how AFR and exploratory behaviour are related to basal metabolic rate (BMR).3Inter-specific variation in exploratory behaviour was positively correlated with AFR. Both AFR and exploration behaviour were negatively correlated with BMR. These results remained significant when taking phylogeny into account.4We suggest that species occupying unproductive and unpredictable environments simultaneously benefit from high exploration, low BMR and delayed AFR because exploration increases the likelihood of finding scarce resources, whereas low BMR and delayed reproduction enhance survival during frequent resources shortages.5This study provides the first empirical evidence for a link between personality, life-history, phylogeny and energy metabolism at the inter-specific level. The superficial-thorough exploration continuum can be mapped along the fast–slow metabolic and life-history continua.

Reconciling custom, citizenship and colonial legacies: Ni-Vanuatu tertiary student attitudes to national identity

Nation-building remains a key challenge in Vanuatu. From the origins of this new nation in 1980, it was clear that creating a unifying sense of national identity and political community from multiple languages and diverse traditional cultures would be difficult. This paper presents new survey and focus group data on attitudes to national identity among tertiary students in Vanuatu. The survey identifies areas of common attitudes towards nationalism and national identity, shared by both Anglophone and Francophone Ni-Vanuatu. However, despite the weakening ties between language of education and political affiliation over recent years, the findings suggest that there remain some key areas of strong association between socio-linguistic background, and attitudes to the nation, and national identity. These findings cast new light on the attitudes of likely future elites towards regional, ethnic, intergenerational and linguistic fault lines in Vanuatu and the challenges of building a cohesive sense of political community and national identity.

Nationalism, Britishness and Australian history: the Meaney thesis revisited

In 2001 Neville Meaney published a landmark article which questioned the place of nationalism in Australian historiography. He argued that up to the 1960s Britishness, not nationalism, was the hegemonic marker of identity for Australians, and warned that nationalist historians had fallen into the trap of writing their histories through nationalism’s own teleological imperative. This article revisits Meaney’s hegemonic claim for the role of Britishness in Australian history by arguing that he went too far. By leeching out nationalism as an ideology at play in Australian politics in the mid-twentieth century historians are in danger of taking Australian history out of its world historical context: the Age of Decolonisation.

The complex and contested history of democracy

Democracy has never been more popular. It is successfully practiced today in a myriad of different ways by people across virtually every cultural, religious or socio-economic context. The forty-five essays collected in this companion suggest that the global popularity of democracy derives in part from its breadth and depth in the common history of human civilization. The chapters include exceptional accounts of democracy in ancient Greece and Rome, modern Europe and America, among peoples’ movements and national revolutions, and its triumph since the end of the Cold War. However, this book also includes alternative accounts of democracy’s history: its origins in prehistoric societies and early city-states, under-acknowledged contributions from China, Africa and the Islamic world, its familiarity to various Indigenous Australians and Native Americans, the various challenges it faces today in South America, Eastern Europe, the Middle East and Asia, the latest democratic developments in light of globalization and new technologies, and potential future pathways to a more democratic world. Understanding where democracy comes from, where its greatest successes and most dismal failures lie, is central to democracy’s project of inventing ways to address the need of people everywhere to live in peace, freedom and with a say in the decisions that affect their lives.

Soluble fish : picture words in a limitless sea — surrealist poetics and a history of the unconscious

This article discusses the Surrealist text 'Soluble Fish' by Andre Breton against prevailing and dominant paradigms of language and the unconscious. Drawing on the theories of Freud, Jacques Lacan, Gilles Deleuze and Felix Guattari, it considers desire as ‘lack’ versus desire as a productive force entirely necessary for life and ‘becoming’. In addition, using an extract of my own creative practice, I propose the taxonomy of ‘new Surrealism’—a contemporary interpretation of the Surrealist’s productive force, also known as the ‘Marvellous.’

Eurocentrism and the history of democracy

Building atop these earlier works, this article offers a fresh critique of the work of Dunn and other political scientists and historians who have propagated the Eurocentric history of democracy. The papers argues that such work can be dissected and critiqued along several key lines: their reliance on a distinctly patriarchal discourse riddled with prejudices; the assertion that one can understand the history of democracy via the etymology of the word itself; and the deeply Eurocentric roots of the study of democracy’s past embedded in the canon of Western political thought. The paper concludes by calling on contemporary political scientists and political historians concerned with the history of democracy to be careful in re-iterating this deeply flawed history of democracy and to instead work towards a history of democracy that retrieves the silenced histories and the forgotten democratic moments that lay behind the roar of Western power.

Cancer and life-history traits: lessons from host-parasite interactions

Despite important differences between infectious diseases and cancers, tumour development (neoplasia) can nonetheless be closely compared to infectious disease because of the similarity of their effects on the body. On this basis, we predict that many of the life-history (LH) responses observed in the context of host-parasite interactions should also be relevant in the context of cancer. Parasites are thought to affect LH traits of their hosts because of strong selective pressures like direct and indirect mortality effects favouring, for example, early maturation and reproduction. Cancer can similarly also affect LH traits by imposing direct costs and/or indirectly by triggering plastic adjustments and evolutionary responses. Here, we discuss how and why a LH focus is a potentially productive but under-exploited research direction for cancer research, by focusing our attention on similarities between infectious disease and cancer with respect to their effects on LH traits and their evolution. We raise the possibility that LH adjustments can occur in response to cancer via maternal/paternal effects and that these changes can be heritable to (adaptively) modify the LH traits of their offspring. We conclude that LH adjustments can potentially influence the transgenerational persistence of inherited oncogenic mutations in populations.

The last of Australian imperial dreams for the Southwest Pacific: Paul Hasluck, the Department of Territories and a Greater Melanesia in 1960

This paper is a study of the vision held at the beginning of the 1960s by Paul Hasluck, the minister for external territories, and his department of the path to decolonisation for Melanesia. Faced by the ongoing West New Guinea crisis, Hasluck and his officials proposed to keep the western part of New Guinea out of Indonesian hands by expanding Australia’s empire, step by step, to include most of Melanesia. This greater Melanesian empire would eventually be guided to self-government. The proposal stood in a long line of ideas by Pacific-minded Australians going back for 100 years for an expanded Australian empire in the southwest Pacific. Consequently the Menzies cabinet’s rejection of Hasluck’s proposal was not just an important step towards changing its policy towards WNG; it marked the end to a century of Australian dreams and designs of a greater formal empire in the southwest Pacific.

Feudal tenure and native title: revising an enduring fiction

This article argues that the feudal doctrine of tenure continues to endure as the foundation for Australian land law despite its obvious social and historical irrelevance. The doctrine of tenure is a derivation of feudal history. The article examines some of its historical foundations with the aim of highlighting the disparity between the fiction of this inherited form and the reality of a colonial Australian landscape. Particular attention is given to the fact that Australian feudal tenure was always a passive framework. It was disconnected with the landscape and therefore incapable of responding to the needs of colonial expansion. This resulted in a clear disparity between feudal form and the reality of a land system populated by statutory grants. The article argues that feudal tenure was never truly devised as a responsive land system but rather, adopted as a sovereignty device. In this sense, legal history was utilised with the aim of promoting imperial objectives within colonial Australia. Tenure was equated with absolute Crown ownership over all Australian territory despite the fact that this was inconsistent with the orthodox tenets of feudal tenure.
The article argues that the consequence of adopting feudal tenure and absolute Crown ownership has been the estrangement of indigenous rights, title and culture. The creation and legitimisation of a land framework with a fundamentally Eurocentric perspective completely destroyed indigenous interests during the settlement and colonial era. It created an imperial ideology where colonists silently accepted the denial of indigenous identity. The decision of the Mabo High Court to reassess this historical perspective and accept the validity of proven native title claims clearly disturbed tenurial assumptions. However, the High Courts' reification of the feudal form created a fundamental paradox: indigenous title was accepted as a proprietary right within a framework incapable of and unequipped to recognise the fundamentally different cultural perspectives of customary ownership. The article argues that native title cannot evolve within a common law framework that regards ownership as a derivation of the English Crown. It is suggested that ultimately, a pluralist property culture, where indigenous and non-indigenous title exist as equalised entities, can only be properly nurtured with the full and absolute abolition of the feudal doctrine of tenure.

Colonial designs: Thomas Karsten and the planning of urban Indonesia

Thomas Karsten (1885 – 1945) is undoubtedly a major figure in the history of architecture and town planning in Indonesia. Between 1915 and 1941 he was involved in town planning in 12 of the 19 municipalities and towns in Java (the most prominent exception being Surabaya) 3 of the 9 towns in Sumatra, and the only town in Borneo This paper does not attempts to investigate or question his importance in this field but to place his architectural and town planning ideas in the context of his broader politico-cultural ideas and activities in the Dutch East Indies between 1914 and 1942, and these, in turn, in the context of an evolving colonialism and colonial discourse.
