Manage one beach or two? Movements and space-use of the threatened hooded plover (Thinornis rubricollis) in south-eastern Australia

An understanding of space use and dispersal of a wildlife species is essential for effective management. We examined the movements of a beach-dwelling, threatened population of hooded plover (Thinornis rubricollis) in southern central Victoria, Australia, by analysing sightings of colour-banded birds (4897 sightings; 194 birds tracked for up to 9 years). Most movements were relatively short (5050 ± 305 m), with 61.4% <1 km and 95.3% <20 km; they lacked directional or sexual bias. The extent of coastline used by individual birds was 47.8 ± 58.0 km. Regional differences in average distances moved by adults were apparent. For adults, movement rates (mean distance per day) were higher during the non-breeding season than during the breeding season. Non-breeding adults generally remained close to their partners (non-breeding, 456.3 ± 163.9 m; breeding, 148.2 ± 45.3 m). Largest flock sizes were recorded during the non-breeding period, and flocking was not uniformly distributed along the coast but appeared to be concentrated in particular locations. The frequency of pair cohesion (i.e. when the distance between partners was zero on a given day) was similar during the breeding (69.6%) and non-breeding seasons (67.7%). Breeding territories (kernel analysis) were 36.7 ± 5.7 ha and overlapped from year to year in all cases (23 pairwise comparisons; 47.9 ± 7.1% overlap). The high fidelity and constancy of territories confirms they warrant ongoing management investment, although the species relies on a matrix of breeding and non-breeding sites. The latter appear to occur in specific parts of the coast and warrant enhanced protection and more research attention. Fragmentation of the breeding population might occur where habitat is rendered unsuitable for > ~50 km.

‘We should change ourselves, but we can’t’: accounts of food and eating practices amongst British Pakistanis and Indians with type 2 diabetes

Objective(s). To look at food and eating practices from the perspectives of Pakistanis and Indians with type 2 diabetes, their perceptions of the barriers and facilitators to dietary change, and the social and cultural factors informing their accounts.

Method. Qualitative, interview study involving 23 Pakistanis and nine Indians with type 2 diabetes. Respondents were interviewed in their first language (Punjabi or English) by a bilingual researcher. Data collection and analysis took place concurrently with issues identified in early interviews being used to inform areas of investigation in later ones.

Results. Despite considerable diversity in the dietary advice received, respondents offered similar accounts of their food and eating practices following diagnosis. Most had continued to consume South Asian foods, especially in the evenings, despite their perceived concerns that these foods could be 'dangerous' and detrimental to their diabetes control. Respondents described such foods as 'strength-giving', and highlighted a cultural expectation to participate in acts of commensality with family/community members. Male respondents often reported limited input into food preparation. Many respondents attempted to balance the perceived risks of eating South Asian foodstuffs against those of alienating themselves from their culture and community by eating such foods in smaller amounts. This strategy could lead to a lack of satiation and is not recommended in current dietary guidelines.

Conclusions. Perceptions that South Asian foodstuffs necessarily comprise 'risky' options need to be tackled amongst patients and possibly their healthcare providers. To enable Indians and Pakistanis to manage their diabetes and identity simultaneously, guidelines should promote changes which work with their current food practices and preferences; specifically through lower fat recipes for commonly consumed dishes. Information and advice should be targeted at those responsible for food preparation, not just the person with diabetes. Community initiatives, emphasising the importance of healthy eating, are also needed.

Higher leptin levels in Asian Indians than Creoles and Europids : a potential explanation for increased metabolic risk

Background and purpose: Leptin predicts cardiovascular diseases and type 2 diabetes, diseases to which Asian Indians are highly susceptible. As a risk marker, leptin’s intra-individual and seasonal stability is unstudied and only small studies have compared leptin levels in Asian Indians with other populations. The aim of this study was to explore ethnicity related differences in leptin levels and its intra-individual and seasonal stability.

Methods: Leptin and anthropometric data from the northern Sweden MONICA (3513 Europids) and the Mauritius Non-communicable Disease (2480 Asian Indians and Creoles) studies were used. In both studies men and women, 25- to 74-year old, participated in both an initial population survey and a follow-up after 5–13 years. For the analysis of seasonal leptin variation, a subset of 1780 participants, 30- to 60-year old, in the Vasterbotten Intervention Project was used.

Results: Asian Indian men and women had higher levels of leptin, leptin per body mass index (BMI) unit (leptin/BMI) or per cm in waist circumference (WC; leptin/waist) than Creoles and Europids when adjusted for BMI (all P<0.0005) or WC (all P<0.005). In men, Creoles had higher leptin, leptin/BMI and leptin/waist than Europids when adjusted for BMI or WC (all P<0.0005). In women, Creoles had higher leptin/BMI and leptin/waist than Europids only when adjusted for WC (P<0.0005). Asian Indian ethnicity in both sexes, and Creole ethnicity in men, was independently associated with high leptin levels. The intra-class correlation for leptin was similar (0.6–0.7), independently of sex, ethnicity or follow-up time. No seasonal variation in leptin levels was seen.

Conclusion: Asian Indians have higher levels of leptin, leptin/BMI and leptin/waist than Creoles and Europids. Leptin has a high intra-individual stability and seasonal leptin variation does not appear to explain the ethnic differences observed here.

Bathymetry and frontal system interactions influence seasonal foraging movements of lactating subantarctic fur seals from Marion Island

Sixteen lactating subantarctic fur seals Arctocephalus tropicalis were satellite-tracked during the winter of 2006 (n = 6), summer of 2006/07 (n = 6) and autumn/winter (n = 4) of 2007, from Marion Island, Southern Ocean. Despite varied individual movement patterns, a favoured foraging area lay to the northeast of the island. In contrast to findings for populations at similar latitudes, seals from Marion Island did not undertake short overnight foraging trips, but trips consistently went beyond 300 km from the island. This aligns with the at-sea duration of lactating seals’ foraging trips from temperate Amsterdam Island, but differs from subantarctic Crozet and Macquarie islands. Time spent at sea, maximum distances travelled and movement variation of tracks from the island varied seasonally. Faecal analysis suggests the diet comprised primarily myctophid fish with limited seasonal variation. Well-defined areas of restricted movement coincided with significant bathymetric features to the west/northwest of the Crozet Plateau, with the Del Caño Rise clearly being important. Positive and negative sea-surface height anomalies (compared to the mean) appeared to be preferred by most seals across seasons. Higher summer sea-surface temperatures correlated with the movements of some seals. Higher chlorophyll a concentrations dictated transit and foraging areas during summer. Bathymetrically influenced oceanographic variables likely explain these preferred long-distance eastward movements. The Îles Crozet and Marion island subantarctic fur seals differ in their foraging ecology despite being neighbours. Conversely, the subantarctic fur seal populations from the distant Amsterdam and Marion islands appear to be similarly influenced by such environmental factors.

Evaluating the distributional implications of price movements : methodology, application and Australian evidence

This article investigates the distributional implication of relative price movements in Australia. It proposes and applies a method of evaluating the nature and size of the inequality bias of price movements. In the process, the study introduces a new demographic demand model that yields sensible and statistically significant estimates of the general equivalence scale and the size economies of scale. The study finds that relative price movements in Australia during the 1990s had an inequality increasing bias and that this bias increased in the late 1990s and the first part of the new millennium. The disaggregated analysis of the inequality movements shows that the regressive nature of relative price changes affected the renters much more than non-renters. The study also provides evidence on the decomposition of overall inequality between demographic groups and compares the decomposition between the nominal and real expenditure inequalities.

Estimating survival and movements using both live and dead recoveries : a case study of oystercatchers confronted with habitat change

1. Animals facing partial habitat loss can try to survive in the remaining habitat or emigrate. Effects on survival and movements should be studied simultaneously since survival rates may be underestimated if emigrants are not considered, and since emigrants may experience reduced survival.

2. We analysed movements and survival of adult wintering oystercatcher Haematopus ostralegus in response to the 1986–1987 partial closure of the Oosterschelde in the Dutch Delta. This reduced by one-third the tidal area of this major European wintering area for waders.

3. We developed a novel variant of a multistate capture–recapture model allowing simultaneous estimation of survival and movement between sites using a mixture of data (live recaptures and dead recoveries). We used a two-step process, first estimating movements between sites followed by site-specific survival rates.

4. Most birds were faithful to their ringing site. Winter survival was negatively affected by winter severity and was lowest among birds changing wintering site (i.e. moving outside of the Oosterschelde).

5. During mild winters, survival rates were very high, and similar to before the closure in both changed and unchanged sectors of the Oosterschelde. However, the combined effect of habitat loss with severe winters decreased the survival of birds from changed sectors and induced emigration.

6. The coastal engineering project coincided with three severe winters and high food stock, making assessment of its effects difficult. However, the habitat loss seems to have had less impact on adult survival and movements than did winter severity.

7. Synthesis and applications. Human-induced habitat change may result in population decline through costly emigration or reduced survival or reproduction of individuals that stay. Long-term monitoring of marked individuals helps to understand how populations respond to environmental change, but site-specific survival and movement rates should be integrated in the same model in order to maximize the information yield. Our modelling approach facilitates this because it allows the inclusion of recoveries from outside the study area.

Dancing the building : movements between bodies and built structures

The thesis elucidates a process by which the layers of perceptions experienced by dancers when using the built environment were developed to create a shared group compositional language.  This study draws on the work of architects, artists and philosphers interested in documenting and analyzing our sensory and affective relations with the built environment.

Intimacy and making : thinking constellations of consciousness and the movements of invention

This paper takes up the three terms - creativity, consciousness and intimacy - and positions them as possible ‘ultimate terms’. Inquiring into the use of these terms to garner approval, status or power within cultural contexts, the paper attempts to unpack them, and simultaneously to seek out any structural similarities in the ways that they operate. The term ‘creativity’ is deconstructed via a Derridean framework, wherein ‘inventiveness’ is posited as a more rigorous alternative in most cases. Consciousness is read closely in relation to its association with notions of awareness and ‘enlightenment’. And ‘intimacy’ is playfully explored as an alternative term for enlightenment, a manoeuvre which brings to the fore some structural assumptions about that which intimacy might comprise. The assumption of intimacy as a spatially-dependent notion is also interrogated. The paper contends that intimacy may involve an unsettling of spatial assumptions proper, and therefore not be simply a function of closeness or distance. It draws on Serres’ notion of the angel as messenger and as analogy for the preposition, indicator of position, but occupant of none. Finally an example from art practice is offered, one that arguably performs the terms intimacy and creativity at once: an epistolary adventure in poetry and photographs, called The Post Project.

Multifaith movements in ultramodernity

Ultramodernity (Willaime 2006), following on from modernity, has been characterised as an era of fear, risk and uncertainty and paradoxically as a time of great hope and global interdependence (Baumann 2006; Beck 2006; Obama 2006). Following the events of September 11, 2001, the Bali and London bombings, a climate of fear has inspired a plethora of policies that have eroded civil liberties, jeopardising trust in state systems and thereby inadvertently elevating the risk of further violence, particularly in so-called Western societies. Conversely, ultramodern scholars, including Jürgen Habermass and Ulrich Beck, have advocated cosmopolitan solutions to more effectively and cooperatively counter global risks. These optimistic scenarios, while reaching populist proportions, have also received their fare share of criticism (Brassett 2008). Indeed, when we look toward the current state of the United Nations it is difficult not to lose hope. Where is the proof that Immanuel Kant’s cosmopolitan condition is coming into being in the global arena beyond these sociological theories? I argue that the rise of multifaith movements in ultramodernity provides this much needed evidence.

Netpeace and the cosmopolitan condition : multifaith movements and the politics of understanding

The ultramodern era has been characterized paradoxically as one of great fear and great hope. Reactions to the tragic events of September 11, 2001 provide evidence of this ambivalence whereby a politics of fear and exclusion permeated Western societies, accompanied by a growing interest in collaborative cosmopolitan solutions addressing the most pressing global risks of our times. Culturally, religiously and linguistically diverse (CRALD) community experiences in the state of Victoria, Australia well illustrate this dichotomy. Drawing on this case study, I argue that the rise of multifaith and multi-actor peacebuilding networks in ultramodernity provide evidence that cosmopolitan solutions can effectively counter global risks, in this case particularly terrorism, and advance common security among diverse faith communities and across diverse sectors. In so doing I develop a new netpeace framework arguing that the politics of fear is best countered by a politics of understanding.
