This is the story of an extraordinary Aboriginal woman, Princy Carlo, and the identity of place she and her descendants fashioned within the confines of the Aboriginal settlement of Cherbourg (formerly Barambah), during the early twentieth century. The patch of Cherbourg that came to be known as 'Chinatown' has to date attracted cursory reference in historical commentary on the south-eastern Queensland Aboriginal settlement. Yet, hidden beneath what may appear as an inconsequential historical detail lies a fascinating illustration of the negotiation of place identity within a frame of triangulated group relations (Aboriginal-Chinese-White) in what remained, in essence, a colonial society. Incorporating primary written sources and oral accounts from descendants the study analyses the forging of the Chinatown identity of place through a process of 'spatial othering', eliciting features unique to this indigenous identity-construct. The study provides an insight into Aboriginal connection and kinship with land following forced removal to a government settlement, and contributes to the historical records of the Cherbourg Aboriginal community and the Eidsvold district in Queensland, Australia.

In socially monogamous birds, females may express mate preferences when they first select a breeding partner, through divorce and subsequent breeding dispersal to a new partner and through extrapair mating. We examined settlement patterns, divorce and breeding dispersal in a sedentary Australian passerine, the brown thornbill (Acanthiza pusilla), in relation to two traits known to influence extrapair paternity (male age and male size). Settlement decisions, divorce and territory switching behaviour were all female strategies that reduced their likelihood of breeding with 1-year-old males. Females preferred to settle in territories with 2+ -year-old males, were more likely to divorce 1-year-old males, and only switched territories if they had an opportunity to form a new pair bond with an old male. In contrast, female settlement and divorce decisions were not influenced by male size. Female thornbills obtain a direct benefit from preferring older males as social mates because breeding success improves with male age in brown thornbills. Nevertheless, divorce rates in this species were low (14% of pair bonds were terminated by divorce), and individuals rarely switched territories following the death of a mate. Both of these mating strategies appeared to be primarily constrained by the distance adults moved to initiate a new pair bond (1-2 territories) and by the limited availability of unpaired older males in the immediate neighbourhood.

The practice of participatory planning in discrete Indigenous settlements has been established since the early 1990s. In addition to technical and economic goals, participatory planning also seeks community development outcomes, including community control, ownership and autonomy. This paper presents an evaluation of one such planning project, conducted at Mapoon in 1995. The Plan successfully improved physical infrastructure and housing, but had mixed success in terms of community development. Despite various efforts to follow participatory processes, the Plan was essentially a passing event, community control progressively diminished after its completion, and outcomes fell short of notions of ownership and autonomy. This suggests some misunderstandings between the practice of participatory planning and the workings of governance.

Secondary metabolites synthesised by sessile invertebrates appear to play a role in creating and maintaining space on hard substrata by repelling competitors. In this study, we investigated the responses of the larvae of the ascidian Herdmania curvata to haliclonacyclamine A (HA), the major component of a suite of cytotoxic alkaloids extracted from the sponge Haliclona sp. 628. Both Haliclona sp. 628 and Herdmania curvata inhabit the crest and slope of Heron Island Reef. High rates of settlement were induced in competent H. curvata larvae by a range of concentrations of HA, all lower than that naturally occurring in the sponge. HA did not induce precompetent larvae to settle. Although early metamorphosis of HA-induced larvae was normal, larvae exposed to all but the lowest concentration of HA were developmentally arrested after completion of tail resorption, at about 4 h after the initiation of metamorphosis. These postlarvae underwent extensive cellular necrosis within 24 h. We also demonstrate that the addition of a transcriptional inhibitor, actinomycin D, to larvae also causes inhibition of metamorphosis after tail resorption is completed. Analyses of incorporation of radiolabelled nucleotides to measure levels of transcription during normal development and after the addition of the transcriptional inhibitor indicate that there is a significant burst of transcriptional activity just after tail resorption is completed. Despite inhibiting metamorphosis at the same stage as actinomycin D, HA increases initial rates of RNA synthesis after induction of metamorphosis in a manner similar to that observed in normal postlarvae until the onset of cellular necrosis. We conclude that HA initially induces H. curvata larvae to settle and progress through early metamorphosis possibly by engaging the same pathway as other artificial and environmental cues but subsequently inhibits completion of metamorphosis, resulting in death of the postlarvae. Since HA does not affect overall transcription rates, it appears to disrupt another important developmental process during early metamorphosis.
