With 450,000 km2 Kobresia (syn. Carex) pygmaea dominated pastures in the eastern Tibetan highlands are the world's largest pastoral alpine ecosystem forming a durable turf cover at 3000–6000 m a.s.l. Kobresia's resilience and competitiveness is based on dwarf habit, predominantly below-ground allocation of photo assimilates, mixture of seed production and clonal growth, and high genetic diversity.
Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly. Here, the past and present distribution Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly.

An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. The physical properties of these functions are studied and possible applications are suggested. A fragmentation model for multigl
To investigate the reasons why companies engage in Corporate Social Responsibility, CSR, this study conducts a survey with 47 companies and interviews with 7 company representatives in the UK. This empirical data and results are analysed in terms of theoretical ideas of CSR and economics. Board of Directors or top management, Attract employees, Reputation, Moral, and Economic reasons are, as in th
Abstract Organically managed cereal fields have a higher plant diversity compared to conventionally managed fields. The presence and spatial distribution of plant resources may affect the spatial relationships between prey organisms and their predators and could therefore alter the feeding relationships between predators and pest prey. As invertebrate predators play an important role in biologica
Metangas bidrar med en signifikant andel till den rådande växthuseffekten på jorden. I nutid är den största källan till utsläpp av metangas våtmarker i jämförelse med andra naturliga utsläppskällor. Emissioner av metangas från våtmarker är beroende av klimatet och har den egenskapen att ge en positiv återkoppling till klimatändringen. Icke desto mindre finns det dock stor osäkerhet associerat med Popular science Global warming is a significant environmental problem now-a-days. Methane is a major greenhouse gas causing global warming by trapping long wave radiations from the Earth. Presently, natural wetlands are responsible for the largest amount of emissions of this gas when compared to other natural sources. Changing climate impacts the emissions from wetlands which in turn further inten
Systematic mass rape during warfare has been used throughout history. This research investigated how mass rape of women have been used as a weapon in Yugoslavia wars between 1992 and 1995. Material from the trials of Dragan Zelenovic, Dragoljub Kunarac, Radomir Kovac and Zoran Vukovic, all of them accused of rape against humanity during the Yugoslavia war, is analyzed in detail with the use of Pos
Prominent research of creativity and affect has historically illuminated the relationship between positive affect and creativity, whereas little is known about the effects- influence of negative affect on creativity. The present study aimed to investigate how negative affect influenced creativity by using a divergent and convergent creativity task. A sample of 54 participants was recruited and ran
The consequences of climate change for bird populations have received much attention in recent decades, especially amongst cavity-nesting songbirds, yet little has been written on ducks (Anatidae) despite these being major elements of wetland diversity and important quarry species. This paper reviews the major known consequences of climate change for birds in general, and relates these to the limi
There is increasing interest in the use of arbuscular mycorrhizal fungi (AMF) for ecological restoration, as AMF can improve plant nutrition and growth. However, some AMF can have negative effects on plant growth. It is therefore critical that restoration strategies incorporate appropriate AMF. This research investigated differences in growth and survival of Podocarpus cunninghamii (mountain tōtar
In generally, there is a phenomenon of “free rider” in the establishment of national oil reserves for different countries, which means that they have the tendency of underestimating the strategic oil reserves. This paper attempts to explain this phenomenon from the perspective of non-cooperative game theory. It also analyzes the establishment of strategic oil reserve among different countries base
To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. Com
This paper looks at al-Qaida and the nearly decade of war through concepts offered by a scientific paradigm called complexity theory. The networks, organization and ideology of al-Qaida in this paper are described in terms of complex adaptive systems, emergent networks with localized behavior. How Al-Qaida in the face of adversity of being one of the most hunted organizations, networks and ideolog
Nationalism and populism are growing phenomenon in a changing Europe. When the concept of the nation-state is questioned or challenged, the political discourses regarding national identity are changing aswell. Since the rapid change in post-communist Central-and Eastern Europe, questions regarding national identity have risen on the region’s political agenda. Nationalists and populists have taken
This paper is a discourse analysis of the concept of equality between men and women in the village Enkokidongoi in southern Kenya. Through interviews with persons connected to the village it explores how thoughts and opinions about equality between men and women are formulated, but also whether equality between men and women is seen as a goal in the community. These thoughts and opinions are analy
Abstract: This thesis treats the subject of rural development and nonfarm development in particular with a focus on community-based tourism. With support and examples from old development theories the aim is to explore how rural development in today’s world differs from the time of the industrial revolution and what that shift looks like. A case study of Buliisa district Uganda, stands as example
This second edition of the infrared microwindow atlas contains a collection of spectral mi- crowindows commonly used or recently suggested for ground-based, high resolution, infrared solar absoption spectroscopy. These solar observations are aimed at quantifying the abun- dance of trace species in the terrestrial atmosphere. A microwindow is a narrow spectral interval that allows to observe a spec
