Heron and Masthead Islands in the Capricorn Group of the Great Barrier Reef Marine Park support major nesting colonies of the wedge-tailed shearwater. The distribution pattern of shearwater nesting burrows was established for particular habitats on both islands by means of a nearest neighbour analysis. Areas of Pisonia grandis forest had the highest burrow density and near-random distribution patterns for burrows while the island fringes had the lowest densities and higher degrees of aggregation. These results may reflect the importance of social communication within a wedge-tailed shearwater colony. Burrows are distributed in patches around the margins of the colony where clear and fringe habitats are represented, but randomly near the centre in Pisonia areas, where sheer numbers may negate the need for further aggregation.  相似文献

Urban brownfields redevelopment in Canada: the role of local government   总被引:2,自引:0,他引:2  
As in many U.S. and European cities, the legacy of a negligent past has left scars on Canada's urban landscape in the form of numerous under-used industrial and commercial brownfield sites. While governments in the U.S. and Europe have implemented a variety of policies and programs to help developers overcome the costs and risks associated with redeveloping these sites, there continues to be apprehension among stakeholders in Canada that efforts implemented by the different levels of government here have been deficient, fragmented and piecemeal in comparison. This paper examines the nature of the brownfields problem in Canadian cities and investigates the role of local governments in managing these problems 'on the ground'. Survey data from 24 cities, coupled with information gathered from four site visitations, reveal that brownfields are indeed a problem for many cities. The data suggest that even though perceptions of what is needed to better manage the problem locally are relatively similar throughout the country, managerial efforts remain disparate and somewhat limited because of diverse provincial policies and variable property markets.  相似文献

Delivery of the potential mutual benefits for biodiversity conservation and Indigenous peoples through protected area co‐management remains challenging, with partnership arrangements frequently delivering inequitable outcomes that marginalise Indigenous interests. In the Kimberley region of Western Australia, Miriuwung‐Gajerrong people initiated a Cultural Planning Framework to help achieve greater equity in planning for co‐management of the first Indigenous‐owned protected areas managed with the state. Analysis of the negotiation and delivery of this Indigenous‐controlled planning initiative concluded it made a key contribution in shaping an equitable intercultural space for ongoing negotiation of co‐management. A practitioners' model of related design concepts drawn from the analysis identified three factors of significance: a foundation platform of recognition of rights and interests; a set of effective organisations to support the roles of the key actors; and effective mechanisms for working together. The model proved robust when evaluated against international standards for best practice, suggesting it may be a useful tool for guiding better uptake of those standards. Interrogation of the two major theories underpinning these standards – common pool resource (CPR) and governance – demonstrated the theories are synergistic and inform different parts of the model. Both theories highlight the significance of Indigenous‐controlled planning. Attention to relational theory for interrogation of the intercultural space may help illuminate their relative importance. Further investigation of the potential of Indigenous‐controlled planning to build theory and practice in Indigenous co‐management of protected areas is recommended.  相似文献

Since the loss of their empires, Britain and France have been seen as states in historical but still only relative decline: no longer great powers but not typical of the large category of middle‐range powers. Despite financial constraints and limited size they retain their status as permanent members of the UN Security Council and continue to display the ambition to exert global influence. At times, London and Paris deal with this anomaly by acting in harness but at others their foreign policies diverge dramatically, not least because of the contrasting domestic traditions from which they emerge, and because of their differing roles within the European Union. This article assesses the capacity of these two notable states to maintain a leading role in international politics given their own uneasy relationship and the significant constraints which they now face, both external and internal. The article is a revised version of the Martin Wight Memorial Lecture, held at Chatham House, London, on 3 November 2015.  相似文献

East Asia and the Asia–Pacific are core components of the global economy, and there have been important recent developments in the regionalism of both regions. After the 1997–1998 financial crisis, East Asian countries initiated more exclusive regional cooperation and integration ventures mainly through ASEAN Plus Three, but lately this process has stumbled. The Asia–Pacific Economic Cooperation (APEC) forum has also failed to make substantial progress. Attention has instead increasingly turned to free trade agreements (FTAs), yet these have hitherto been overwhelmingly bilateral in nature. There are still only a few truly regional FTAs in East Asia and the Asia–Pacific—and these are on a sub‐regional scale. However, various frustrations over the messy and fractious pattern of heterogeneous bilateral agreements led to the recent initiation of ‘grand regional’ FTA talks. The Trans‐Pacific Partnership (TPP) is an Asia–Pacific‐based, United States‐led project while the Regional Comprehensive Economic Partnership (RCEP) is an East Asia‐centred project. Each contains highly diverse memberships and the successful conclusion of TPP and RCEP talks is not assured. It is argued that, if negotiated, the RCEP is more likely to advance meaningful and effective regionalism than the TPP due to the former ascribing more importance to regional community‐building. Furthermore, bilateral FTAs already in force may over the long term transform into more comprehensive economic agreements that address new regional and global challenges such as energy security and climate change.  相似文献

Uniformities and discontinuities in Chinese culture have long animated anthropological debates. The books reviewed here reflect an emerging scholarly consensus about the diversity of China, expressed not only in religions and populations marginal to more mainstream Chinese culture, but among the Han Chinese themselves. Much of the discussion of China's diversity hinges on identity, a social phenomenon freighted with rhetoric and sentiment and inflected by the forces of local and national politics.  相似文献
