The diet of Asian badger, <Emphasis Type="Italic">Meles leucurus</Emphasis> Hodgson, 1847, in Samarovskii Chugas Nature Park,Western Siberia

The diet structure of Asian badgers (Meles leucurus Hodgson, 1847) on Bol’shoi Chukhtinskii Island (Samarovskii Chugas Nature Park, Khanty-Mansi Autonomous Area) was studied by means of coprological analysis. Ten diet components were identified, including Siberian stone pine seeds (pine nuts), berries, earthworms, larval and adult insects, fishes, amphibians, reptiles, and mammals. The proportion of pine nuts was especially large. Seasonal fluctuations in the occurrence frequency and abundance of different foods were insignificant, but some of them were found to markedly vary between years.     

The idea of sustainable development

In this lecture, I demonstrate how very different macroeconomic history begins to look if Nature is included as a capital asset in production activities. The tentative conclusions I draw from the evidence are: (1) high population growth in the world’s poorest regions (South Asia and sub-Saharan Africa) has been an obstacle to the achievement of sustainable economic development there; relatedly, (2) when population growth is taken into account, the accumulation of manufactured capital, knowledge, and human capital (health and education) has not compensated for the degradation of natural capital in South Asia and sub-Saharan Africa and, in all probability, even in the UK and the US; (3) China is possibly an exception to (1) and (2). This article is based on the Keynote Lecture delivered at the international symposium on “Sustainability in an Unequal World”, held in Tokyo on November 24, 2006. The exposition relies on my book, Economics: A Very Short Introduction, Oxford University Press, Oxford, 2007. The author is the Frank Ramsey Professor of Economics at the University of Cambridge and a Fellow of St. John’s College, Cambridge.

基于冲击模型方法的自然保护区可靠性研究:以草海为例

自然保护区是受特殊保护和管理的一类特殊的可靠性系统。本文从可靠性视角出发,利用冲击模型方法和MATLAB随机模拟技术,以贵州草海为例分析自然保护区系统的寿命行为和失效规律。分析结果表明:(1)20世纪50年代以前,草海系统受到的人为干预相对较少,可靠性长期保持相对稳定。以人类活动为主的冲击影响始于20世纪50年代末,对保护区生态功能产生了强烈干预。(2)在1958—1980期间,政府出于防涝减灾考虑的引流排水行为扮演了系统的主要冲击,对其可靠性产生了毁灭性影响。(3)在1980年之后的30多年里,周边农民出于造田增地需求的排水毁林自发性活动则形成草海保护区的新一轮冲击,并持续影响着系统的生态功能。(4)目前草海在调节气候、缓解灾害、保持生物多样性方面的生态功能已严重弱化。如果最近几十年的人为冲击模式不能得到有效缓解,保护区系统极有可能在近期内再次发生功能性崩溃。

Intraspecific variation of <Emphasis Type="Italic">Oxytropis chankaensis</Emphasis>, a Far Eastern Endemic

Variation and intraspecific differentiation of Oxytropis chankaensis Jurtz. (Fabaceae), a plant endemic to the Russian Far East, have been studied by analyzing a complex of morphological characters. A high level of morphological variation has been revealed, and the most variable populations growing in the Khankaiskii Nature Reserve have been identified. Populations growing in the zone of anthropogenic impact are characterized by low values and reduced variability of test characters. Distinct morphological differentiation of O. chankaensis populations has been observed.     

The effectiveness of environmental education workshops for teachers,learners and schools in Malaysia

In Malaysia, various efforts have been introduced to increase the knowledge, skills and awareness of citizens to the benefit of the environment by means of a variety of programmes. However, uncertainty about the effectiveness of environmental education programmes and the way they contribute to sustainability still exists. This paper reports on an evaluation of the Kelab Pencinta Alam (KPA) (School Nature Clubs) programme organised by the Malaysia Nature Society and the Forest Research Institute of Malaysia. The Kellogg Logic Model was used as an evaluative instrument as the impact of the programme had to be determined. This was done through questionnaires to teachers and principals in KPA schools. School visits were also undertaken to evaluate workplace success and to validate the findings from the questionnaires. Overall, the evaluation showed a high level of success for the programme.     

An integrated approach for studying the land suitability for ecological corridors through spatial multicriteria evaluations

Nature conservation is a very important issue in the sustainability assessments and spatial planning context. Knowledge of the suitability of the land to behave as an ecological corridor thus provides very significant input to land-use planning. Nature conservation and land-use planning are by their nature spatial problems. A family of methods that are rapidly gaining traction for planning and policymaking, named spatial multicriteria evaluations (SMCE), which are based on geographic information systems (GIS) and multicriteria analysis (MCA) coupling, can be an effective support for this area. The present paper proposes the integration of the GIS with a specific MCA technique, named Analytic Network Process to assess the ecological value of the land in the Piedmont Region (northern Italy). The results are obtained in the form of maps to be used as decision variables in planning. The study concludes with some lessons learned during the development of the SMCE and highlights that the applied methodology is an effective tool for decision makers in spatial planning and strategic assessments.     

Feral horses (<Emphasis Type="Italic">Equus caballus</Emphasis>) as a component of protected steppe ecosystems in the Rostovskii Nature Reserve

Vegetation was considerably trampled throughout Vodnyi Island in the Rostovskii Nature Reserve in 2007 because of a high pasture load due to feral horses (0.15 horses/ha). Calculation of the food resources on the island, with its protection as part of a nature reserve taken into account, has shown that the herd size is 3.5 times larger than the maximum allowable value.     

A roadmap to a green chemical industry in Australia

A ‘roadmap’ has been devised for a progressive greening of the Australian chemical industry over the next two decades. The roadmap is based on a set of interactive principles broadly termed ‘economic’, ‘social’, ‘technological’, ‘environmental’ and ‘political’, which collectively form the ‘drivers of change’ in chemical industry strategy/business/policy planning—leading to greater efficiency and economic sustainability of this industry. The proposed roadmap pre-supposes that real economic, societal and environmental benefits can be obtained through greater use of existing and emerging green chemical technology. It can play an important role in developing a sustainable chemical industry in Australia. Primarily, the proposed roadmap involves a paradigm shift of the business operating plan and a significant mindset change of management.     

Impact of fires on the fauna of terrestrial arthropods in protected steppe ecosystems

The abundance of terrestrial arthropods in the Orenburgskii Nature Reserve has decreased since its establishment in 1989. At present, this parameter fluctuates considerably, and the species composition of arthropods is changing in favor of xerobiontic and eurybiontic species. These changes result from the absence of grazing load as well as from periodic fires. Therefore, it is necessary to organize controlled livestock grazing and reliable fire protection in reserved areas.     

Experience in mapping the ecological state of the plant cover

Objectives and methods of mapping the ecological state of the plant cover at different spatial levels—federal, regional, and local—are analyzed. The maps used as examples are as follows: at the federal level, “Ecological State of Rangelands in Russia” (1:10 000 000); at the regional level, “Vegetation of Moscow Oblast” (1:200 000); and at the local level, “Vegetation of Narofominskii Raion” and “Current State of the Plant Cover in Narofominskii Raion” (1:50 000).     

Trends in the spatial distribution of Asiatic black bear cubs

Trends in adaptation to new habitats of orphaned bear cubs in the period of rearing and after release into the wild have been revealed. The pattern of their distribution in a biotope is contingent on its exploration in search for food, with the intensity and scale of this process increasing as the animals grow. The results indicate that the methods of rearing used in the Ussuri Nature Reserve are effective and promising.
