An integrative research framework for enabling transformative adaptation
Transformative adaptation will be increasingly important to effectively address the impacts of climate change and other global drivers on social-ecological systems. Enabling transformative adaptation requires new ways to evaluate and adaptively manage trade-offs between maintaining desirable aspects of current social-ecological systems and adapting to major biophysical changes to those systems. We outline such an approach, based on three elements developed by the Transformative Adaptation Research Alliance (TARA): (1) the benefits of adaptation services; that sub-set of ecosystem services that help people adapt to environmental change; (2) The values-rules-knowledge perspective (vrk) for identifying those aspects of societal decision-making contexts that enable or constrain adaptation and (3) the adaptation pathways approach for implementing adaptation, that builds on and integrates adaptation services and the vrk perspective. Together, these elements provide a future-oriented approach to evaluation and use of ecosystem services, a dynamic, grounded understanding of governance and decision-making and a logical, sequential approach that connects decisions over time. The TARA approach represents a means for achieving changes in institutions and governance needed to support transformative adaptationThe research was supported by CSIRO Land and

Making Peace with the Earth—The Diplomatic Turn
Considering the proliferation of global systemic risks in the Anthropocene, this short paper expresses the need to reframe sustainability as the acquisition and invention of symbiotic and regenerative diplomatic skills to make peace with the Earth, i.e. to preserve and restore the conditions of its habitability. This post-environmental paradigm shift reflects the deep transformation that is now underway in our understanding of the Earth, not as a planetary system nor as a reservoir of resources, but as a web of meanings and interactions. It manifests the social-ecological as well as the ethical implications of precaution
Forms of Experienced Environments: Questioning Relations Between Humans, Aesthetics, and Sciences
International audience"This book explores 'environmental forms' in terms of their relationships to the socio-politico-ecological transformations currently in progress. Today, the environment is a central theme in political discourse, scientific work and everyday life. It is multi-dimensional: it is a living space, a socio-ecological system and a field of research and action. However, despite the presence and diversity of existing approaches, the ways in which policies address environmental issues remain mainly focused on control, highlighting the techno-ecological, managerial and curative dimensions of public actions. Although public action tends to instrumentalise the environment, the humanities and social sciences have initiated significant reflections in this field, proposing alternative ways of thinking about the environment in its multiple aspects and scales. As part of 'another approach' to the environment that mirrors contemporary developments, this book adopts a form-based approach which has been largely neglected by previous studies dealing with environmental themes. The analyses provided here will open up a new perspective on the relationships between people, aesthetics and environments, and are drawn from different schools of research, highlighting the huge potential of reading the environment through forms or, conversely, a reading of environmental forms.

The DUF1013 protein TrcR tracks with RNA polymerase to control the bacterial cell cycle and protect against antibiotics
How DNA-dependent RNA polymerase (RNAP) acts on bacterial cell cycle progression during transcription elongation is poorly investigated. A forward genetic selection for Caulobacter crescentus cell cycle mutants unearthed the uncharacterized DUF1013 protein (TrcR, transcriptional cell cycle regulator). TrcR promotes the accumulation of the essential cell cycle transcriptional activator CtrA in late S-phase but also affects transcription at a global level to protect cells from the quinolone antibiotic nalidixic acid that induces a multidrug efflux pump and from the RNAP inhibitor rifampicin that blocks transcription elongation. We show that TrcR associates with promoters and coding sequences in vivo in a rifampicin-dependent manner and that it interacts physically and genetically with RNAP. We show that TrcR function and its RNAP-dependent chromatin recruitment are conserved in symbiotic Sinorhizobium sp. and pathogenic Brucella spp Thus, TrcR represents a hitherto unknown antibiotic target and the founding member of the DUF1013 family, an uncharacterized class of transcriptional regulators that track with RNAP during the elongation phase to promote transcription during the cell cycle
Adaptive β-lactam resistance from an inducible efflux pump that is post-translationally regulated by the DjlA co-chaperone
The acquisition of multidrug resistance (MDR) determinants jeopardizes treatment of bacterial infections with antibiotics. The tripartite efflux pump AcrAB-NodT confers adaptive MDR in the polarized α-proteobacterium Caulobacter crescentus via transcriptional induction by first-generation quinolone antibiotics. We discovered that overexpression of AcrAB-NodT by mutation or exogenous inducers confers resistance to cephalosporin and penicillin (β-lactam) antibiotics. Combining 2-step mutagenesis-sequencing (Mut-Seq) and cephalosporin-resistant point mutants, we dissected how TipR uses a common operator of the divergent tipR and acrAB-nodT promoter for adaptive and/or potentiated AcrAB-NodT-directed efflux. Chemical screening identified diverse compounds that interfere with DNA binding by TipR or induce its dependent proteolytic turnover. We found that long-term induction of AcrAB-NodT deforms the envelope and that homeostatic control by TipR includes co-induction of the DnaJ-like co-chaperone DjlA, boosting pump assembly and/or capacity in anticipation of envelope stress. Thus, the adaptive MDR regulatory circuitry reconciles drug efflux with co-chaperone function for trans-envelope assemblies and maintenance
An integrative research framework for enabling transformative adaptation
International audienceTransformative adaptation will be increasingly important to effectively address the impacts of climate change and other global drivers on social-ecological systems. Enabling transformative adaptation requires new ways to evaluate and adaptively manage trade-offs between maintaining desirable aspects of current social-ecological systems and adapting to major biophysical changes to those systems. We outline such an approach, based on three elements developed by the Transformative Adaptation Research Alliance (TARA): (1) the benefits of adaptation services; that subset of ecosystem services that help people adapt to environmental change; (2) The values-rules-knowledge perspective (vrk) for identifying those aspects of societal decision-making contexts that enable or constrain adaptation and (3) the adaptation pathways approach for implementing adaptation, that builds on and integrates adaptation services and the vrk perspective. Together, these elements provide a future-oriented approach to evaluation and use of ecosystem services, a dynamic, grounded understanding of governance and decision-making and a logical, sequential approach that connects decisions over time. The TARA approach represents a means for achieving changes in institutions and governance needed to support transformative adaptation
An indicator framework for assessing ecosystem services in support of the EU Biodiversity Strategy to 2020
In the EU, the mapping and assessment of ecosystems and their services, abbreviated to MAES, is seen as a key action for the advancement of biodiversity objectives, and also to inform the development and implementation of related policies on water, climate, agriculture, forest, marine and regional planning. In this study, we present the development of an analytical framework which ensures that consistent approaches are used throughout the EU. It is framed by a broad set of key policy questions and structured around a conceptual framework that links human societies and their well-being with the environment. Next, this framework is tested through four thematic pilot studies, including stakeholders and experts working at different scales and governance levels, which contributed indicators to assess the state of ecosystem services. Indicators were scored according to different criteria and assorted per ecosystem type and ecosystem services using the common international classification of ecosystem services (CICES) as typology. We concluded that there is potential to develop a first EU wide ecosystem assessment on the basis of existing data if they are combined in a creative way. However, substantial data gaps remain to be filled before a fully integrated and complete ecosystem assessment can be carried out.ISSN:2212-041
Cross-Validation Study for Epidermal Growth Factor Receptor and KRAS Mutation Detection in 74 Blinded Non-small Cell Lung Carcinoma Samples: A Total of 5550 Exons Sequenced by 15 Molecular French Laboratories (Evaluation of the EGFR Mutation Status for the Administration of EGFR-TKIs in Non-Small Lung Carcinoma [ERMETIC] Project-Part 1).
International audienceINTRODUCTION:: The Evaluation of the epidermal growth factor receptor (EGFR) Mutation status for the administration of EGFR-Tyrosine Kinase Inhibitors in non-small cell lung Carcinoma (NSCLC) (ERMETIC) project part 1 assessed the accuracy of EGFR and KRAS mutations detection in NSCLC among 15 French centers. METHODS:: The 15 ERMETIC centers selected 74 NSCLC surgical specimens from previously untreated patients. Paraffin and paired frozen DNA were sequenced for EGFR exons 18 to 21 and KRAS exon 2 by an external molecular laboratory, yielding a gold standard. The 74 blinded paraffin DNAs were redistributed to the 15 ERMETIC laboratories for sequencing of a total of 5550 exons. Results were compared with the gold standard and between centers by discordance rates and kappa statistics. RESULTS:: The gold standard included 39 mutated samples with 22 EGFR and 17 KRAS mutated samples. Kappa statistics showed that 10, 6, and 6 of the 15 ERMETIC centers had a moderate to good kappa score, when compared with external laboratory for EGFR exon 19, EGFR exon 21, and KRAS exon 2, respectively. Kappa statistics showed moderate score between centers which increased to good for EGFR exon 19 mutation when removing 16 poor-quality samples with high nonamplificable rates. CONCLUSIONS:: Paraffin-embedded specimens may represent a suitable source of DNA for sequencing analyses in ERMETIC centers. EGFR exon 19 deletions were most accurately detected by ERMETIC centers. Ease and accuracy of results, depended more on the quality of sample than on the difference in molecular sequencing procedures between centers, emphasize the need of preanalytical quality control programs
