Reproduction of the Siberian spruce in the timberline ecotone of the Iremel’ Massif

Quantitative and qualitative characteristics of cones and seeds and the emergence and survival of seedlings in the Siberian spruce (Picea obovata Ledeb.) were studied in different parts of the timberline ecotone on the Iremel’ Massif, the Southern Urals, from 2003 to 2006. In the productive year 2003, a decrease in the number of cones (from 110000 to 3000 per hectare), the yield of seeds (from 13 × 10⁶ to 0.09 × 10⁶ per hectare), and their laboratory germination rate (from 34 to 14%) with an increase in elevation above sea level was recorded. In 2004, significant differences in the number of seedlings per hectare were revealed between the lower, middle, and upper parts of the ecotone (85 200, 19 800, and 0–400 ind., respectively). It has been shown that the greater part of seedlings (76–96%) perish during the first cold period. New generations of spruce trees are formed only after productive years. Seed production and seedling mortality in spruce apparently depend not only on air temperature and soil moistening but also on snow depth and soil temperature, which change more abruptly along the altitudinal gradient.     

Analysis of the Difference of the Basic Pension by Regions

Nowadays, the disparity of the basic pension in local regions of China can be described as follows: the low level of the unification of the basic pension systems, the large disparity of the level of the basic pension, and unfairness of the enterprises’ payment for the basic pension in different local regions in China. These have already brought many negative influences, which have greatly held back the development of the society and national economy. We should build the basic pension system in all local regions of China as a whole, which can cover all people and decrease the disparity in different local regions in China.     

Packaging redesign – benefits for the environment and the community

Abstract

This paper aims to underline the importance of the packaging redesign process and the potential benefits that can be derived from this for both the environment and the community. The research demonstrates that the redesign of paper corrugated packaging has cost savings for most links of the supply chain such as the industrial customers, retailers, wholesalers and final consumers. In addition, an applied case study will be used that aims to provide evidence that the redesign process could further offer weight and transportation benefits, provide better environmental performance and finally offer better protection for the packaged products. The alternative packaging suggestions made in the research refer to the secondary paper corrugated packaging since the objective is to show the value of the redesign process. The research provides the tools for a packaging designer, on how to estimate, analyse, redesign and compare different approaches, finding the way to a more sustainable packaging supply chain.     

Reintroduction of the european bison into the forest ecosystem of the Orlovskoe Poles’e National Park

The forest ecosystem of the Orlovskoe Polese National Park has been studied in reference to the reintroduction of a rare species: the European bison (Bison bonasus L.). Preliminary data characterizing the state of forest resources and the populations of ungulates living in the forests, as well as the genetic problems associated with maintaining a viable population of the European bison, are considered.Translated from Ekologiya, No. 2, 2005, pp. 132–137.Original Russian Text Copyright © 2005 by Belousova, Smirnov, Kazmin, Kudrjavtsev.

Effects of the Bacterial Component on the Viability of the Paramecium bursariaSymbiotic Complex (Infusorian–Zoochlorella)

A hypothesis is considered that the establishment and maintenance of mass exchange processes in the Paramecium bursariasymbiotic complex (infusorian–alga) depends on the presence of the third component—bacteria—whose role is underestimated but essential for completing the exchange cycle. The role of this component in the symbiotic cycle of Paramecium bursariais possible to reveal using special bactericidal preparations specifically inhibiting the bacteria involved in the metabolic cycle but having no effect on the functions of the host cell and the zoochlorella population. Experiments with various preparations of this type were performed, and the response to treatment was estimated from growth rates of the symbiotic complex and its components. This allowed identification of an antibiotic (rifampicin) that had no adverse influence on free-living zoochlorella and chlorella-free paramecia (the basic components of the symbiotic cycle) but drastically inhibited the growth of the P. bursariasymbiotic complex, which could be interpreted as evidence in favor of the hypothesis concerning the existence of the third symbiotic component.     

Plutonium isotopes in the lower reaches of the River Rhône over the period 1945-2000: fluxes towards the Mediterranean Sea and sedimentary inventories

Plutonium isotopes in the Rh?ne River originate from both the weathering of the catchment basin contaminated by global atmospheric fallout, and the liquid effluents released from the Marcoule reprocessing plant since 1961. Due to a new treatment process applied to the liquid effluents, a decrease of two orders of magnitude in the industrial plutonium discharged into the River Rh?ne has been registered from 1991. Today, 238Pu industrial inputs to the River Rh?ne are still about 10 times higher than those derived from global fallout, while 239+240Pu inputs from industrial and global fallout sources are of similar importance, i.e. 1 GBq y(-1). Our results indicate that the river sedimentary compartment act either as a sink or a delayed-source term of plutonium for the freshwaters depending on the hydraulic regime and flood events. This compartment may then represent an important industrial delayed-source term for the River Rh?ne freshwaters in the coming years as the Marcoule reprocessing plant is being dismantled. These results were obtained from samples collected from the lower course of the River Rh?ne over the 1987-1998 period and analysed for 238Pu and 239+240Pu activities. Both river sedimentary inventories of plutonium isotopes and effective outputs from the River Rh?ne towards the Gulf of Lions have been estimated for each year over the 1945-2000 period. Regarding 239+240Pu, the sedimentary inventory accumulated since 1945 is estimated to be 172+/-35 GBq. If mobile, this amount represents a significant delayed-source term of plutonium on the scale of the Rh?ne watershed.     

Will the application of Ammonium-Ferric-Hexacyano-Ferrate enhance the vertical migration of radiocaesium?

The consideration of a possible enhanced vertical migration of radiocaesium with the application of ammonium-ferric-hexacyano-ferrate (AFCF) as countermeasure, due to the colloidal nature of AFCF, made us set up a series of migration experiments. For the study two soil types were considered, which were either left unplanted or cultivated with ryegrass. Two AFCF concentrations, 1 and 10 g m^-2, and an untreated control were applied. A simple diffusion–convection model was fitted to the data.The application of AFCF did not enhance the downward migration of radiocaesium in the profile. Moreover, for an unplanted sandy soil the application of AFCF significantly retarded the migration: 10 g AFCF m^-2 decreased the convection term, V, from 0·78 to 0·42 cm a^-1 and the diffusion component, D, from 0·21 to 0·09 cm² a^-1. For all other experimental conditions (unplanted loamy soil, ryegrass cultivated sandy and loamy soil), the application of AFCF did not have any effect on radiocaesium migration. Since AFCF does not promote the vertical migration of radiocaesium, enhanced groundwater contamination is improbable.     

Study of the Optimization and Adjustment ofthe IndustrialStructure Subjected to Water Resource in the Drainage Area of the Yellow River

Since the 1990s, the Yellow River stream has been temporarily interrupted for several years, which affects the development of society, the economy and human life, limits the economic potential of the drainage areas, and especially causes great harm to regions on the lower reaches. Based on the analysis of the relationship between the development of society and economy and water scarcity, the author thinks it is necessary to optimize and adjust the industrial structure that has extravagantly consumed enormous amounts of water, and to develop ecological agriculture, industry and tourism which are balanced with the ecological environment. Finally, the author puts forward several pieces of advice and countermeasures about how to build the economic systems by which water can be used economically.

Managing the rural–urban transformation in East Asia in the 21st century

This article explores the special features of the rural–urban transformation in East Asia in the last 30 years within the broader context of the development strategies of Asian governments. Despite an ongoing commitment to the rhetoric of concern with rural development, food security and the alleviation of rural poverty, these policies have emphasised the important role of urbanisation as the prime process influencing economic growth. This is supported by the economic argument that the economies of scale, the creation of mass urban markets and the higher productivity that occur in urban places make them crucial to development. This paper argues that this approach creates a false dichotomy between rural and urban areas, whereas development should aim to increase the linkages between rural and urban areas aimed at producing societal transformations rather than separate rural and urban transitions. The paper then explores the empirical evidence of rural–urban transitions in East Asia with a more detailed case study of China, which is considered to be a crucial example because of the size of its population, the special conditions of market socialism and its institutional capacity to manage the rural–urban transformation. The final section focusses on the importance of developing spatial sensitivity to the management of the rural–urban transformation in the 21st century. Old divisions between rural and urban sectors must be replaced by planning that integrates urban and rural activities so that they adopt sustainable management strategies which utilise concepts of eco-systems in which rural and urban activities are linked, so as to create sustainable urban regions, cities and societies.

Population Analysis of Sables in the Ural–Ob Region of the Species Range

An attempt at population analysis of sables in the Ural–Ob region of the species range was made with the use of vast biological material (craniometry, 1909 specimens; ecological structure, 2157 specimens; and coat color, 439169 pelts). Population groups in the region were mainly described on the basis of morphological, geographic, historical, and ecological criteria. Seven spatially separated population groups were found, which were named after the main rivers of their habitats: the Tavda–Konda–Sos'va, Dem'yanka, Salym–Yugan, Agan–Vakh, Kazym–Nazym, Nadym–Kunovat, and Pur–Taz groups. They distinctly differed from one another with respect to cranial measurements, coat color, and some structural demographic parameters. In some cases, morphological differences reached the subspecies level. The data obtained make it possible to revise the pattern of geographic variation within the species range.     

On the Flood Disasters in the Lower Jingjiang Reaches: Grey Prediction Model and Application

1 INTRODUCTION Located in the transition area of the natural zones between north and south as well as the typical subtropical zone featured with warm-wet in the summer and cool-moisture in the winter (Shen, 1986; Chen et al., 2001), the MiddleYangtze reach is of great importance in the development and flood control of this region (Chen et al., 2001; Yin and Li, 2001). Due principally to the special geological setting and geographic location, the lower Jingjiang reach, typical of vast fl…     

Water Environmental Degradation of the Source Area of the Yellow River on Northeast Qinghai-Tibet Plateau

1 INTRODUCTION Environmental changes caused by mankind's exploitation and regional climate changes have long been a severe problem in the world, especially in the arid and semiarid areas because of their ecosystems' vulnerability (Chen & Qu, 1992; Wang & Cheng, 1999; Liu et al., 1999). During the last half-century, especially the last 30 years, drastic environmental changes have occurred owing to exploitation and development, which have invoked society's concerns. In the Qinghai-Tibet …     

Humble Opinions on the Relationship between the Percentage of Urban Residents in an Urban Region and the Economic Status in This Region in China

It is a fact that in U.S. the immigration between rural areas and city areas is free, but in China this type of immigration is restricted by HUKOU system （Hukou, namely the household registration system, was designed to control rural-urban in China）. All of those national policies in city areas are much better than those in rural areas, so those corresponding differences bring about great discrepancy of the economic status （mainly including GDP per person and income per resident） between rural and city areas in the same urban region, especially in different urban re- gions because the percentage of urban residents in those urban regions is in-equable. The present paper mainly researches the topic of relationship between the percentage of urban residents and the economic status in an urban region in China, including the relationship between the economic and the political functions of a settlement in China during the process of urbanization.     

Importance of colloids in the transport within the dissolved phase (<450 nm) of artificial radionuclides from the Rhône river towards the Gulf of Lions (Mediterranean Sea)

The significance of colloidal fractions regarding the transport of artificial radionuclides in natural water systems is underlined by using sequential ultrafiltration both in the Rh?ne freshwater and the marine area under and outside the influence of the river outflow. Indeed, the Rhodanian aquatic system represents an interesting test site as various artificial radionuclides are released into the Rh?ne river by several nuclear installations. We focused our study on (137)Cs, (106)Ru, (60)Co, (238)Pu and (239+240)Pu. Our results show that Fe, Al and Organic carbon (OC) are the main components of colloidal matter. Colloids represent about 15% of dissolved (<450 nm) OC and 25% of dissolved Fe and Al exported towards the sea. Within the dissolved (< 450 nm) phase, these colloidal compounds are shown to account for the transport of 40% for both Co and Ru, 60% for (238)Pu and (239+240)Pu and have no significance on (137)Cs flux.     

A method to derive the relationship between the annual and short-term air quality limits—Analysis using the WHO Air Quality Guidelines for health protection

The World Health Organization (WHO) Air Quality Guidelines (AQG) were launched in 2006, but gaps remain in evidence on health impacts and relationships between short-term and annual AQG needed for health protection. We tested whether relationships between WHO short-term and annual AQG for particulates (PM₁₀ and PM_2.5) and nitrogen dioxide (NO₂) are concordant worldwide and derived the annual limits for sulfur dioxide (SO₂) and ozone (O₃) based on the short-term AQG. We obtained air pollutant data over seven years (2004–2010) in seven cities from Asia-Pacific, North America and Europe. Based on probability distribution concept using maximum as the short-term limit and arithmetic mean as the annual limit, we developed a new method to derive limit value one from another in each paired limits for each pollutant with capability to account for allowable exceedances. We averaged the limit derived each year for each city, then used meta-analysis to pool the limit values in all cities. Pooled mean short-term limit for NO₂ (140.5 μg/m³ [130.6–150.4]) was significantly lower than the WHO AQG of 200 μg/m³ while for PM₁₀ (46.4 μg/m³ [95CI:42.1–50.7]) and PM_2.5 (28.6 μg/m³ [24.5–32.6]) were not significantly different from the WHO AQG of 50 and 25 μg/m³ respectively. Pooled mean annual limits for SO₂ and O₃ were 4.6 μg/m³ [3.7–5.5] and 27.0 μg/m³ [21.7–32.2] respectively. Results were robust in various sensitivity analyses. The distribution relationships between the current WHO short-term and annual AQG are supported by empirical data from seven cities for PM₁₀ and PM_2.5, but not for NO₂. The short-term AQG for NO₂ should be lowered for concordance with the selected annual AQG for health protection.     

What Is the Environment Doing in My Report? Analyzing the Environment-as-Stakeholder Thesis through Corpus Linguistics

This paper seeks to explore whether business organizations' claims to regard the natural environment as a stakeholder are consistent with the way in which the environment is represented in their corporate social responsibility reporting. It applies corpus linguistic methods to analyze statistical regularities and differences in the discursive construction of core stakeholders, such as customers and employees, and that of the natural environment. Results show that the representation of the environment is not characterized by the agency and capacity for engagement that characterizes other stakeholders. While organizations overtly acknowledge a duty toward the environment, the dominant lexical and grammatical patterns in which it is represented tend to obscure the organization's responsibilities and emphasize its mitigating actions instead. Although the argument for regarding the environment as a stakeholder is based on the fact that it places objective and compelling demands on our actions, we look in vain for recognition of such demands in organizational reporting.     

An analysis of China’s investment in the hydropower sector in the Greater Mekong Sub-Region

The Mekong River’s natural resources offer large benefits to its populations, but it also attracts the interest of foreign investors. Recently, Chinese firms, banks and government bodies have increasingly invested in large hydropower projects in the Greater Mekong Sub-Region. Due to China’s rapid economic growth, its rapid industrialisation and its limited domestic natural resources, the Chinese government has issued the ‘Going Out Strategy’ which promotes investments in overseas natural resources like water and energy resources. In search for climate-friendly low-carbon energy, cheap electricity and access to a growing market, Chinese institutions turn to Southeast Asia where Chinese institutions are currently involved in more than 50 on-going large hydropower projects as contractors, investors, regulators and financiers. These Chinese institutions have influence on environmental and social practices as well as on diplomatic and trade relations in the host countries. Currently, there are major gaps in understanding who is engaged, why, how and with what impacts. This paper therefore aims to assess the motives, actors, beneficiaries and the direct and indirect impacts of China’s investment in large hydropower projects in the Greater Mekong Sub-Region. The authors use the ‘Rising Powers Framework’ to assess these issues, which is an adapted version of the Asian Drivers Framework.
