Between Conservation and Development: Concretizing the First World Natural Heritage Site in the Alps Through Participatory Processes

This article presents an empirical interdisciplinary study of an extensive participatory process that was carried out in 2004 in the recently established World Natural Heritage Site “Jungfrau–Aletsch– Bietschhorn” in the Swiss Alps. The study used qualitative and quantitative empirical methods of social science to address the question of success factors in establishing and concretizing a World Heritage Site. Current international scientific and policy debates agree that the most important success factors in defining pathways for nature conservation and protection are: linking development and conservation, involving multiple stakeholders, and applying participatory approaches. The results of the study indicate that linking development and conservation implies the need to extend the reach of negotiations beyond the area of conservation, and to develop both a regional perspective and a focus on sustainable regional development. In the process, regional and local stakeholders are less concerned with defining sustainability goals than elaborating strategies of sustainability, in particular defining the respective roles of the core sectors of society and economy. However, the study results also show that conflicting visions and perceptions of nature and landscape are important underlying currents in such negotiations. They differ significantly between various stakeholder categories and are an important cause of conflicts occurring at various stages of the participatory process.

Integration of a World Heritage Site in an agricultural environment in the Simen Mountains (Ethiopia)

The conflict between nature-orientated conservation and man-orientated rural development is examined, along with the degree to which ecological research contributes to mountain development, and whether conservation areas can be protected from being areas of natural resources ultimately to be used by man in life-threatening need. A high mountain national park in Ethiopia is taken as an example within UNESCO's concept of Biosphere Reserves. The main finding is that conservation without development will fail, and therefore the focus is more on the area surrounding a national park than on the park itself. A buffer zone must be developed as an economically stable and socially secure area for man, so that his needs do not drive him to exploit the last natural resource area in his vicinity. Simen is a World Heritage Site for future generations. Man and nature, development and conservation, belong together in this unique mountain area.

Making the most of world natural heritage - linking conservation and sustainable regional development?

Today, more than 1000 World Heritage (WH) sites are inscribed on UNESCO’s list, 228 of which are natural and mixed heritage sites. Once focused primarily on conservation, World Natural Heritage (WNH) sites are increasingly seen as promoters of sustainable regional development. Sustainability-oriented regions, it is assumed, are safeguards for conservation and positively influence local conservation goals. Within UNESCO, discussions regarding the integration of sustainable development in official policies have recently gained momentum. In this article, we investigate the extent to which WNH sites trigger sustainability-oriented approaches in surrounding regions, and how such approaches in turn influence the WNH site and its protection. The results of the study are on the one hand based on a global survey with more than 60% of the WNH sites listed in 2011, and on the other hand on a complementary literature research. Furthermore, we analyze the policy framework necessary to support WNH sites in this endeavor. We conclude that a regional approach to WNH management is necessary to ensure that WNH sites support sustainable regional development effectively, but that the core focus of WNH status must remain environmental conservation.

Cell mixing induced by myc is required for competitive tissue invasion and destruction

Cell-cell intercalation is used in several developmental processes to shape the normal body plan. There is no clear evidence that intercalation is involved in pathologies. Here we use the proto-oncogene myc to study a process analogous to early phase of tumour expansion: myc-induced cell competition. Cell competition is a conserved mechanism driving the elimination of slow-proliferating cells (so-called 'losers') by faster-proliferating neighbours (so-called 'winners') through apoptosis and is important in preventing developmental malformations and maintain tissue fitness. Here we show, using long-term live imaging of myc-driven competition in the Drosophila pupal notum and in the wing imaginal disc, that the probability of elimination of loser cells correlates with the surface of contact shared with winners. As such, modifying loser-winner interface morphology can modulate the strength of competition. We further show that elimination of loser clones requires winner-loser cell mixing through cell-cell intercalation. Cell mixing is driven by differential growth and the high tension at winner-winner interfaces relative to winner-loser and loser-loser interfaces, which leads to a preferential stabilization of winner-loser contacts and reduction of clone compactness over time. Differences in tension are generated by a relative difference in F-actin levels between loser and winner junctions, induced by differential levels of the membrane lipid phosphatidylinositol (3,4,5)-trisphosphate. Our results establish the first link between cell-cell intercalation induced by a proto-oncogene and how it promotes invasiveness and destruction of healthy tissues.

Destruction, Alteration, Simples and World-Stuff

When a tree is chopped to bits, or a sweater unraveled, its matter still exists. Since antiquity, it has sometimes been inferred that nothing really has been destroyed: what has happened is just that this matter has assumed new form. Contemporary versions hold that apparent destruction of a familiar object is just rearrangement of microparticles or of 'physical simples' or 'world stuff'. But if destruction of a familiar object is genuinely to be reduced to mere alteration of something else, we must identify an alternation proper to the career, the course of existence, of this something else; relatedly, the alteration must be characterizable without asserting the existence of the familiar object. All contemporary views fail one of these requirements.

Osterix inhibits bone destruction in osteosarcoma through transcriptional repression of Interleukin-1alpha expression

Osteosarcoma, a malignant bone tumor, rapidly destroys the cortical bone. We demonstrated that mouse K7M2 osteosarcoma cells were deficient in osterix (osx), a zinc finger-containing transcription factor required for osteoblasts differentiation and bone formation. These cells formed lytic tumors when injected into the tibia. The destruction of bone is mediated by osteoclasts in osteosarcoma. The less expression of osterix with osteolytic phenotype was also observed in more tumor cell lines. Replacement of osterix in K7M2 cells suppressed lytic bone destruction, inhibited tumor growth in vitro and in vivo, and suppressed lung metastasis in vivo and the migration of K7M2 to lung conditioned medium in vitro. By contrast, inhibiting osterix by vector-based small interfering RNA (siRNA) in two cell lines (Dunn and DLM8) that expressed high levels of osterix converted osteoblastic phenotype to lytic. Recognizing and binding of Receptor Activator of NF-κB (RANK) on osteoclast precursors by its ligand RANKL is the key osteoclastogenic event. Increased RANKL results in more osteoclast activity. We investigated whether K7M2-mediated bone destruction was secondary to an effect on RANKL. The conditioned medium from K7M2 could upregulate RANKL in normal osteoblast MC3T3, which might lead to more osteoclast formation. By contrast, the conditioned medium from K7M2 cells transfected with osx-expressing plasmid did not upregulate RANKL. Furthermore, Interleukin-1alpha (IL-1α) was significantly suppressed following osx transfection. IL-1α increased RANKL expression in MC3T3 cells, suggesting that osx may control RANKL via a mechanism involving IL-1α. Using a luciferase reporter assay, we demonstrated that osx downregulated IL-1α through a transcription-mediated mechanism. Following suppression of osterix in Dunn and DLM8 cells led to enhanced IL-1α promoter activity and protein production. Site-directed mutagenesis and Chromatin immunoprecipitation (ChIP) indicated that osterix downregulated IL-1α through a Sp1-binding site on the IL-1α promoter. These data suggest that osterix is involved in the lytic phenotype of osteosarcoma and that this is mediated via transcriptional repression of IL-1α. ^

Concentration and production of bacteria and bacterial destruction in the photic layer of the Sodruzhestvo Sea area, Southern Ocean

Bacterioplankton in the photic layer of the Sodruzhestvo Sea area and adjoining waters consists in summer primarily of cocci, with fractions smaller than 2 ?m predominating. The average abundance and biomass of microorganisms are 427 thousand cells/ml and 438 mg C/m**2, with ranges of 150-1770 thousand cells/ml and 221-1146 mg C/m**2. The average daily production and bacterial destruction increase from 49 and 104 mg C/m**2 at the beginning of the growth period to 85 and 180 mg C/m**2 in the middle of the period and remain at this level till the end. Despite low rate of increase (daily P/B coefficient averages 0.12), because of its high abundance bacterioplankton in Antarctic waters plays a major role in destruction of organic matter, accounting for 60-85% of energy consumed by heterotrophs.
