Conservation biology : a crisis discipline

Conserving biodiversity is of utmost importance on a global scale. Species conservation, however, is a challenging task, which is often compounded by a lack of knowledge of target species. New advances in information technology and molecular techniques, however, are enabling conservation biologists to obtain large amounts of data quickly, which will certainly aid in assigning conservation priorities. This article reviews the use of genetics in conservation biology and highlights, using the Powerful Owl Ninox strenua as an example, how DNA can be a valuable source of data.

Crisis of meanings : divergent experiences and perceptions of the marine environment in Victoria, Australia

The oceans of the world are regularly depicted as under threat from human exploitation with the problem portrayed as being of 'global' concern. In a world market characterised by the division of labour, many of those who eat fish do so without directly experiencing the ocean as a domain of productive utility. Rather, their encounters are with representations that depict the 'natural' world as an aesthetic object of contemplation, and environmentalist discourses that identify human activities as' threatening marine ecosystems. So prevalent is this experience that tangible institutions, such as state fisheries management bodies, have emerged, acting to reinforce the ontology of this 'contemplated' ocean, giving weight to the illusion that humans can, and should, appreciate it only from afar. In this representation, commercial fishers are regularly depicted as transgressing a 'natural' boundary between humans and the environment. It is when the world is simultaneously encountered as an object of consumptive utility and aesthetic utility that the human role in the environment becomes ambiguous and a sense of crisis arises. This paper investigates disjunctions in experiences and understandings that contribute to environmental anxiety, and debates over the appropriate use of the ocean.

Latest Guadalupian brachiopods from the Guadalupian/Lopingian boundary GSSP section at Penglaitan in Laibin, Guangxi, South China and implications for the timing of the pre-Lopingian crisis

A brachiopod fauna comprising nine species in eight genera from three closely spaced stratigraphic horizons of the same stratigraphic section is described for the first time from the Laibin Limestone in the uppermost part of the Maokou Formation in the Guadalupian/Lopingian (G/L) GSSP section at Penglaitan, Guangxi Autonomous Region, South China. The brachiopod assemblages are bracketed between two conodont zones: Jinogondolella xuanhanensis Zone below and Jinogondolella granti Zone above and, therefore, they can be safely assigned to the latest Capitanian in age. However, all but one of the nine brachiopod species from the Laibin Limestone carry strong early Lopingian (Wuchiapingian) aspect. Thus, the discovery of this brachiopod fauna not only suggests that some Lopingian brachiopod species had already appeared in the late Guadalupian (Capitanian); more importantly, it has also highlighted the fact that both the previously noted pre-Lopingian life crisis (or end-Guadalupian or Middle Permian mass extinction) and Lopingian recovery/radiation actually occurred in late Capitanian times, sometime before the G/L chronostratigraphic boundary. So far, the Penglaitan GSSP section provides the highest-resolution disappearance patterns of different fossil groups around the G/L boundary.

Asian studies in "crisis" : is cultural studies the answer?

This article explores some of the benefits and limitations of Cultural Studies in Asian studies with particular reference to the expression of Asian-Australian identity in diaspora. It has been suggested that the influence of Cultural Studies – a discipline that is viewed as more globally relevant – may be an answer to the Asian studies “crisis”. In relation to the Cultural Studies approach to Asian-Australian identity, I argue that the discourse and rhetoric of Cultural Studies is highly beneficial in breaking down stereotypes and rebuilding the national narrative of identity. However, as a methodology it is not without limitations.

Wool industry : a decade of turbulence : an examination of some of the factors contributing to the crisis within Australia's wool industry, and the resulting economic, social and demographic effects on a small isolated rural community

A central issue of this thesis has been an examination of the effects that the current wool crisis has had on the Balmoral district, an area almost solely devoted to the production of wool and wool sheep. Examines the methods being utilised to try to alleviate some of these effects.

Politics of educational crisis

The Chinese symbol for 'crisis' is a combination of the symbols for danger and opportunity. Constructing a sense of crisis is dangerous because crisis discourse mobilises powerful emotions such as concern, fear and desire - particularly when it surrounds something as important to us as our children's education. Using the example of recent crisis discourses surrounding physical education, this thesis examines dangers and opportunities that arise when we declare that our education institutions are in crisis.
