Late palaeozoic global changes affecting high-latitude environments and biotas : an introduction

The Late Palaeozoic Ice Age (LPIA), spanning approximately from ~320 Ma (Serpukhovian, late Mississippian) to 290 Ma (mid-Sakmarian, Early Permian), represents the vegetated Earth’s largest and most long-lasting regime of severe and multiple glaciations, involving processes and patterns probably comparable to those of the Last Ice Age. Accompanying the LPIA occurred a number of broadly synchronous global environmental and biotic changes. These global changes, as briefly reviewed and summarized in this introductory paper, comprised (but are not limited to) the following: massive continental reorganization in the lead up to the final assembly of Pangea resulting in profound changes in global palaeogeography, palaeoceanography and palaeobiogeogarphy; substantially lowered global atmospheric carbon dioxide concentrations (pCO₂), coupled with an unprecedented increase in atmospheric oxygen concentrations reaching Earth's all-time high in its last 600 million year history; sharp global temperature and sea-level drops (albeit with considerable spatial and temporal variability throughout the ice age); and apparently a prolonged period of global sluggish macro-evolution with both low extinction and origination rates compared to other times. In the aftermath of the LPIA, the world's climate entered into a transitional climate phase through the late Early to Middle Permian before its transformation into a greenhouse state towards the end-Permian. In recent years, considerable amount of data and interpretations have been published concerning the physical evidence in support of the LPIA, its broad timeframe and eustatic and ecosystem responses from the lower latitudes, but relatively less attention has been drawn to the impact of the ice age on late Palaeozoic high-latitude environments and biotas. It is with this mission in mind that we have organized this special issue, with the central focus on late Palaeozoic high latitude regions of both hemispheres, that is, Gondwana and northern Eurasia. Our aim is to gather a set of papers that not only document the physical environmental changes that had occurred in the polar regions of Gondwana and northern Eurasia during the LPIA, but also review on the biotic responses at different taxonomic, ecological and spatial scales to these physical changes in a refined chronological timeframe.

This introductory paper is designed to provide a global context for the special issue, with a brief review of key late Palaeozoic global environmental changes (including: changes in global land-sea configurations, atmospheric chemistry, global climate regimes, global ocean circulation patterns and sea levels) and large -scale biotic (biogeographic and evolutionary) responses, followed by a summary of what we see as unresolved scientific issues and various working hypotheses concerning late Palaeozoic global changes and, in particular, the LPIA, as a possible reference to future research.

Annual variation in the distribution of summer snowdrifts in the Kosciuszko alpine area, Australia, and its effect on the composition and structure of alpine vegetation

Australian alpine ecosystems are expected to diminish in extent as global warming intensifies. Alpine vegetation patterns are influenced by the duration of snow cover including the presence of snowdrifts in summer, but there is little quantitative information on landscape-scale relationships between vegetation patterns and the frequency of occurrence of persistent summer snowdrifts in the Australian alps. We mapped annual changes in summer snowdrifts in the Kosciuszko alpine region, Australia, from Landsat TM images and modelled the frequency of occurrence of persistent summer snowdrifts from long-term records (1954–2003) of winter snow depth. We then compared vegetation composition and structure among four classes that differed in the frequency of occurrence of persistent summer snowdrifts. We found a curvilinear relationship between annual winter snow depth and the area occupied by persistent snowdrifts in the following summer (r²=0.9756). Only 21 ha (0.42% of study area) was predicted to have supported summer snowdrifts in 80% of the past 50 years, while 440 ha supported persistent summer snow in 10% of years. Mean cover and species richness of vascular plants declined significantly, and species composition varied significantly, as the frequency of summer snow persistence increased. Cushion plants and rushes were most abundant where summer snowdrifts occurred most frequently, and shrubs, grasses and sedges were most abundant in areas that did not support snowdrifts in summer. The results demonstrate strong regional relationships between vegetation composition and structure and the frequency of occurrence of persistent summer snowdrifts. Reductions in winter snow depth due to global warming are expected to lead to substantial reductions in the extent of persistent summer snowdrifts. As a consequence, shrubs, grasses and sedges are predicted to expand at the expense of cushion plants and rushes, reducing landscape vegetation diversity. Fortunately, few vascular plant species (e.g. Ranunculus niphophilus) appear to be totally restricted to areas where summer snow occurs most frequently. The results from this study highlight potential indicator species that could be monitored to assess the effects of global warming on Australian alpine environments.

Global students for global education research?

In this chapter we discuss the importance of ‘internationalising’ the experience of education research students. First, we look at some features of the increasingly globalised landscape of education and education research and consider three main reasons for urging students to join international networks during their period of study. We then take two examples of contemporary developments in international networking, one at a European level and one at a global level, before concluding by suggesting a number of steps that supervisors and students might take to ensure that they engage effectively with the global education research community.

Global research priorities for sea turtles : informing management and conservation in the 21st century

Over the past 3 decades, the status of sea turtles and the need for their protection to aid population recovery have increasingly captured the interest of government agencies, non-governmental organisations (NGOs) and the general public worldwide. This interest has been matched by increased research attention, focusing on a wide variety of topics relating to sea turtle biology and ecology, together with the interrelations of sea turtles with the physical and natural environments. Although sea turtles have been better studied than most other marine fauna, management actions and their evaluation are often hindered by the lack of data on turtle biology, human–turtle interactions, turtle population status and threats. In an effort to inform effective sea turtle conservation a list of priority research questions was assembled based on the opinions of 35 sea turtle researchers from 13 nations working in fields related to turtle biology and/or conservation. The combined experience of the contributing researchers spanned the globe as well as many relevant disciplines involved in conservation research. An initial list of more than 200 questions gathered from respondents was condensed into 20 metaquestions and classified under 5 categories: reproductive biology, biogeography, population ecology, threats and conservation strategies.

International network for food and obesity/NCD research, monitoring and action support: benchmarking food environments towards healthier diets

Background and objectives: 

Understanding the ontological requirements for collaborative web-based experiential learning

The challenge of human-computer interaction forces educationalists to think of new ways to understand the social, historical and contextual nature of learning. Discussion and exchange of ideas enable learners to learn together. However, the granularity of the Webbased learning context is extensive; consequently, e- Courseware design faces new dilemmas. Only through targeted research will it be known with any certainty whether Web-based learning gives rise to a new type of learning dissonance [1]. It has been proposed that converged theoretical paradigms that underpin particular digitised or context-mediated learning systems are forcing learners into new ways of thinking [2]. This paper presents an overview of the plans for an experimental project designed to understand the ontological requirements for experiential instructional environments. This project is a joint research initiative involving three Universities in the Asia/Pacific region. Results will be used to inform educationalists interested in developing instructional strategies for a global community.

Learning through research : a regional university and its community

Regional universities bring a research capacity to their home locations that is rarely available through other mechanisms in the region. University initiated research projects conducted locally can provide an opportunity for regional communities to examine their practices through a different lens. Through these projects, researchers in regional universities whose research includes sites internal and external to the region are able to connect their region to national and global contexts. Research presents many opportunities for regional universities and their communities to learn together.

There is some evidence that policy-makers are aware of the importance of behavioural relationships in the engagement of regional universities with communities. Policy documents tend to focus on the macro, institutional level benefits, structural incentives and impediments to university and community engagement. This paper examines research from one faculty based on a regional university campus: the Faculty of Education at the University of Tasmania in Launceston in Australia. It takes a micro view, considering benefits and factors influencing success for small research teams and individual researchers and their community research associates. A learning community approach, where synergies from collaboration can generate new knowledge for the benefit of all university and community players, emerges as an effective model for regional engagement through research.

Examining integrated advertising and sponsorship in corporate marketing through televised sport

To determine how integrated TV advertising and event sponsorship should be best managed and evaluated, a theoretical framework derived from global exploratory research of academic literature and consulting reports was validated by 16 experts. To benchmark the current practices against the best practice integration methods, 12 campaigns, which had sponsored a televised event and placed advertisements during the broadcast of the event, were analyzed via case studies. The investigated competitions included the Wimbledon Tennis Tournament in London and the Olympic Games in Sydney. The examined brands comprised automotive, financial services, retail chain, office equipment, and consumer goods. A total of 24 semi-structured in-depth interviews were conducted-two for each case-one interview with an internal marketing executive from the promoted corporation, and a second with an external respondent from the advertising agency, event management organization, market research firm, or television channel. The study identified the key techniques that led to increased corporate sales-four steps and four objectives with necessary performance measures.

Have the health services reoriented at all?

Recently, I had an opportunity to observe the workings of the health care system from the inside. I was admitted to a mixed surgical ward in an Australian public hospital with a mysterious ailment. My personal health required acute promotion.

My participant observation research demonstrated that the calls for action in the Ottawa Charter are still urgent. The Charter, twenty three years ago, stated

The responsibility for health promotion in health services is shared among individuals, community groups, health professionals, health service institutions and governments. They must work together towards a health care system which contributes to the pursuit of health.

The role of the health sector must move increasingly in a health promotion direction, beyond its responsibility for providing clinical and curative services. Health services need to embrace an expanded mandate which is sensitive and respects cultural needs. This mandate should support the needs of individuals and communities for a healthier life, and open channels between the health sector and broader social, political, economic and physical environmental components.

Reorienting health services also requires stronger attention to health research as well as changes in professional education and training. This must lead to a change of attitude and organization of health services which refocuses on the total needs of the individual as a whole person.

A checklist for ecological management of landscapes for conservation

The management of landscapes for biological conservation and ecologically sustainable natural resource use are crucial global issues. Research for over two decades has resulted in a large literature, yet there is little consensus on the applicability or even the existence of general principles or broad considerations that could guide landscape conservation. We assess six major themes in the ecology and conservation of landscapes. We identify 13 important issues that need to be considered in developing approaches to landscape conservation. They include recognizing the importance of landscape mosaics (including the integration of terrestrial and aquatic areas), recognizing interactions between vegetation cover and vegetation configuration, using an appropriate landscape conceptual model, maintaining the capacity to recover from disturbance and managing landscapes in an adaptive framework. These considerations are influenced by landscape context, species assemblages and management goals and do not translate directly into on-the-ground management guidelines but they should be recognized by researchers and resource managers when developing guidelines for specific cases. Two crucial overarching issues are: (i) a clearly articulated vision for landscape conservation and (ii) quantifiable objectives that offer unambiguous signposts for measuring progress.

Encouraging high expectation entrepreneurship : the implications of Australian policy practices

Recent studies have shown the important roles that new high growth firms can play in job creation and economic development. This paper reviews the positioning of present Australian government policies and programs that intend to be supportive of the development of more high growth businesses; that is those that employ greater than twenty persons. The research explores the environments of a group of new high growth Australian firms and the roles that the various identified government support initiatives have played in their development. The paper also draws on recent research on survival and growth patterns of spin-off companies generated by publicly funded research agencies to map the government support initiatives with the different stages of the high growth business life cycle. The paper reviews issues in the Australian business environment that may have affected the rate of generation of new high growth firms. Of particular relevance has been the progressive freeing up of the Australian labour market and a greater resource allocation to research commercialisation by publicly funded research providers. The analysis has finally separately considered how to produce and support more founders of such high growth firms, their future chief executive officers, the specialist consultants and other professional support people and issues related to access to finance that such firms will need. The research findings draw attention to the important role of government financial support for industry research, particularly at the point where the first product is in the market and resources are scarce. At this point support is vital both to increase the market penetration of the core product and for R&D for product customisation and increasing the product range.

A complex connection : community newspapers and tiers of social capital

At a time when newspaper circulations across the globe are plummeting, there is increasing interest in the concept of `local over global' and research linking small newspapers with the `strength of community'. There has been a myriad of definitions on social capital including Coleman, Bourdieu and Putnam which focus on the value of the strength of relationships formed by individuals and groups within communities. While newspaper circulation has been linked to community social capital, little attention has been paid to the way social capital works within the news organisation from those who produce news and information to those who read it. Given the complexity and multiplicity of the sociology of news production, this paper examines the role of organisational social capital in this process and argues Ronald Burt's theory of 'structural holes' (1997) may be an appropriate theoretical lens through which to consider this.
