The gram-positive filamentous bacterium Streptomyces coelicolor has a complex developmental cycle with three distinct phases: growth of the substrate mycelium, development of reproductive structures called aerial hyphae, and differentiation of these aerial filaments into long chains of exospores. During a transposon mutagenesis screen, we identified a novel gene (devA) required for proper development. The devA mutant produced only rare aerial hyphae, and those that were produced developed aberrant spore chains that were much shorter than wild-type chains and had misplaced septa. devA encodes a member of the GntR superfamily, a class of transcriptional regulators that typically respond to metabolite effector molecules. devA forms an operon with the downstream gene devB, which encodes a putative hydrolase that is also required for aerial mycelium formation on R5 medium. S1 nuclease protection analysis showed that transcription from the single devA promoter was temporally associated with vegetative growth, and enhanced green fluorescent protein transcriptional fusions showed that transcription was spatially confined to the substrate hyphae in the wild type. In contrast, devAB transcript levels were dramatically upregulated in a devA mutant and the devA promoter was also active in aerial hyphae and spores in this background, suggesting that DevA might negatively regulate its own production. This suggestion was confirmed by gel mobility shift assays that showed that DevA binds its own promoter region in vitro. [less ▲]

African forest elephants– taxonomically and functionally unique–are being poached at accelerating rates, but we lack range-wide information on the repercussions. Analysis of the largest survey dataset ever assembled for forest elephants (80 foot-surveys; covering 13,000 km; 91,600 person-days of fieldwork) revealed that population size declined by ca. 62% between 2002–2011, and the taxon lost 30% of its geographical range. The population is now less than 10% of its potential size, occupying less than 25% of its potential range. High human population density, hunting intensity, absence of law enforcement, poor governance, and proximity to expanding infrastructure are the strongest predictors of decline. To save the remaining African forest elephants, illegal poaching for ivory and encroachment into core elephant habitat must be stopped. In addition, the international demand for ivory, which fuels illegal trade, must be dramatically reduced. [less ▲]

This study aimed to establish a common Key Performance Indicators (KPIs) framework to report biodiversity for the Gypsum Industry at the European level. An original approach of participatory process has been developed in order to integrate the different opinions and to reach a consensus framework between different stakeholders’ groups: Eurogypsum stakeholders, European and local authorities, universities and consulting offices, European and local associations for the conservation of nature and stakeholders from the mining sector. The strategy is based on five main steps: (i) To build a stakeholders’ network; (ii) ) To build a framework proposal to be submitted to stakeholders by selecting a maximum set of indicators based on the literature and reaching an agreement on indicators with Eurogypsum (Focus Group); (iii) Reaching a consensus framework with all the stakeholders and evaluating feasibility by a Delphi Policy survey, by the analysis of the Environmental Impact Assessments of the Gypsum Industry and by visiting three quarries; (iv) Final validation with Eurogypsum; (v) Creating indicators’ Factsheets and a Eurogyspum report to the destination of the public. The resulting framework contains eleven indicators which are the most acceptable set of indicators for all the stakeholders. It answers to European legislation and strategies for biodiversity. It is intended to improve sustainability in the quarries and to help managing biodiversity, to allow setting up of appropriate reporting systems. It is a flexible framework adaptable given the local context of each gypsum quarry in order to prove if a No Net Loss has been reached at a quarry’s scale. [less ▲]

This study aims to establish a common Key Performance Indicators (KPIs) framework to report biodiversity for the Gypsum Industry at the European level. An original approach of participatory process has been developed in order to integrate the different opinions and to reach a consensus framework between different stakeholders’ groups: - Eurogypsum stakeholders - European and local authorities - Scientific panel : universities and consulting offices - European and local associations for the conservation of nature - Stakeholders from the mining sector The strategy is based on five main steps: (i) To Build a stakeholders’ network; (ii) To build a framework proposal to be submitted to stakeholders by selecting a maximum set of indicators based on the literature and reaching an agreement on indicators with Eurogypsum (Focus Group); (iii) Reaching a consensus framework with all the stakeholders and evaluating feasibility by a Delphi Policy survey, by the analysis of the EIAs of the Gypsum Industry and by visiting three European quarries; (iv) Final validation with Eurogypsum (meeting); (v) Creating indicators’ Factsheets and a Eurogyspum report to the destination of the public. The resulting framework contains eleven indicators which are the most acceptable set of indicators for all the stakeholders. It answers to European legislation and strategies for biodiversity. It is intended to improve sustainability in the quarries and to help managing biodiversity, to allow setting up of appropriate reporting systems. The aim is to maintain the biodiversity status of the gypsum quarries. It is a flexible framework adaptable given the local context of each gypsum quarry in order to prove if a No Net Loss has been reached at a quarry’s scale. [less ▲]

The world agrifood system continues to be in a vulnerable state as we fast approach the 2015 deadline for the Millennium Development Goal of halving the proportion of people suffering from hunger. Although a number of countries have made important changes towards developing food related policies, at the level of the global community, the challenge of food (in)security has not been able push policy makers to develop a common solution to be applied, solution that could include the regional and national specificities registered around the world, while also integrating a global view of increasing agricultural productivity, higher farm competitiveness and without relinquishing the national or individual right for food governance.

Over the past fifteen years, numerous studies have been conducted on the problem of psychological harassment in the workplace. Nevertheless, many challenges remain in this field, both on the scientific level and in terms of intervention and diagnosis. One challenge in particular that remains is that of better observation of the complexity and evolution of situations, taking into account more than one perspective and allowing for several levels of understanding. In this article, we present a case study in which we question all the protagonists in an alleged harassment situation. The data are analysed according to the Liège model. The article presents new findings on the subject of the psycho-socio-managerial dynamics of harassment, particularly the existence of different sources of legitimacy for feeling harassed and the labyrinth of conflictual relationships and victim relationships. The implications of this model in terms of diagnosis and intervention are discussed at the end of the article. [less ▲]

This paper reports the results of a round-table debate organized by the Royal Academy for Overseas Sciences (RAOS) on Developing Countries facing Global Warming: a Post-Kyoto Assessment (Brussels, 13 June, 2009) to highlight the view of developing countries on adaptation to and mitigation of climate change. The participants convened to discuss the various aspects of climate change impacts and adaptation in developing countries preceding the Copenhagen Conference (UNFCCC COP 15) in December 2009. Here, we summarize the point of view of the two invited speakers representing developing countries. [less ▲]
