| Abstract Grape pomace from Vitis labrusca is an important sub-product of the “American table wine” industry. It is recalcitrant to degradation, and its accumulation is a serious problem with negative environmental impacts. We analyzed the ability of five white-rot fungi to transform this residue in-vitro. Mass loss and phenol removal in grape pomace treated with each fungus were compared after 30-day solid-state fermentation. Since Peniophora albobadia isolate LPSC 285 was the fungus that showed the highest degradative ability and the lowest free phenol levels in the residue transformed, we selected this fungus to monitor its effect on this residue after 30, 60, and 90 days of incubation. We analyzed mass loss of the residue caused by the fungus activity... |

| Yeast multi-copy vectors carrying the formaldehyde-resistance marker gene SFA have proved to be a valuable tool for research on industrially used strains of Saccharomyces cerevisiae. The genetics of these strains is often poorly understood, and for various reasons it is not possible to simply subject these strains to protocols of genetic engineering that have been established for laboratory strains of S. cerevisiae. We tested our vectors and protocols using 10 randomly picked baker's and wine yeasts all of which could be transformed by a simple protocol with vectors conferring hyperresistance to formaldehyde. The application of formaldehyde as a selecting agent also offers the advantage of its biodegradation to CO2 during fermentation, i.e., the selecting... |

| Abstract Streptococcus pneumoniae is one of the most frequent opportunistic pathogens worldwide. DNA processing protein A (DprA) is an important factor involved in bacterial uptake and DNA integration into bacterial genome, but its role in S. pneumoniae virulence remains unclear. The aim of this study was to characterize the effects of the pneumococcal dprA gene on the pathogenesis of S. pneumoniae. To construct a dprA-deficient pneumococcal strain, the dprA gene of the S. pneumoniae strain D39 was inactivated. The virulence of this dprA-deficient strain, designated ΔD39, was compared with that of the wild-type strain by evaluating their respective capabilities to adhere to human pulmonary epithelial cells (PEC-A549) and by analyzing their choline-binding... |

| Addressing the environmental challenges of the 21st century requires substantial changes to the way modern society views and manages ecosystems. In particular, many authors contend that fundamental transformation of the largely sectoral, expert-centered ecosystem-management institutions of modern, Western societies is needed. There is increasing agreement that more adaptive, integrated, collaborative ecosystem-management approaches, interlinked at multiple scales, would improve society’s ability to sustainably manage complex social–ecological systems. Therefore, understanding processes of transformation, and factors that may enable transformation in ecosystem management, has become an active research area. We explore... |

| In recent years recurring political, economic, and environmental crises require questioning and re-evaluating dominant pathways of human development. However, political and economic frameworks seem to encompass deeply rooted resistance to fundamental changes (e.g., global financial crisis, climate change negotiations). In an effort to repair the system as fast as possible, those paradigms, mechanisms, and structures that led into the crisis are perpetuated. Instead of preserving conventional patterns and focusing on continuity, crises could be used as an opportunity for learning, adapting, and entering onto more sustainable pathways. However, there are different ways not only of arguing for sustainable pathways of development but also of conceptualizing... |

| Resilience is emerging as a promising vehicle for improving management of social-ecological systems that can potentially lead to more sustainable arrangements between environmental and social spheres. Central to an understanding of how to support resilience is the need to understand social change and its links with adaptation and transformation. Our aim is to contribute to insights about and understanding of underlying social dynamics at play in social-ecological systems. We argue that longstanding indigenous practices provide opportunities for investigating processes of adaptation and transformation. We use in-depth analysis of adaptation and transformation through engagement in participatory action research, focusing on the role of cultural and social... |

| Faced with numerous seemingly intractable social and environmental challenges, many scholars and practitioners are increasingly interested in understanding how to actively engage and transform the existing systems holding such problems in place. Although a variety of analytical models have emerged in recent years, most emphasize either the social or ecological elements of such transformations rather than their coupled nature. To address this, first we have presented a definition of the core elements of a social-ecological system (SES) that could potentially be altered in a transformation. Second, we drew on insights about transformation from three branches of literature focused on radical change, i.e., social movements, socio-technical transitions, and... |

| Climate change and its interactions with complex socioeconomic dynamics dictate the need for decision makers to move from incremental adaptation toward transformation as societies try to cope with unprecedented and uncertain change. Developing pathways toward transformation is especially difficult in regions with multiple contested resource uses and rights, with diverse decision makers and rules, and where high uncertainty is generated by differences in stakeholders’ values, understanding of climate change, and ways of adapting. Such a region is the Murray-Darling Basin, Australia, from which we provide insights for developing a process to address these constraints. We present criteria for sequencing actions along adaptation pathways: feasibility... |

| I examined the multiple visions of the future of the city that can emerge when city actors and organizations reconfigure themselves to address sustainability. In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA) approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city.... |

| Adaptive capacity is widely held as a key property of resilient and transformative social-ecological systems. However, current knowledge of the term does not yet address key questions of how to operationalize this system condition to address sustainability challenges through research and policy. This paper explores temporal and agency dimensions of adaptive capacity in practice to better understand how system conditions and attributes enable adaptation. An institutional dynamics lens is employed to systemically examine empirical cases of change in urban water management. Comparative analysis of two Australian cities' drought response is conducted using institutional analysis and qualitative system dynamics mapping techniques. The study finds that three... |

| Research on the barriers and limits to climate change adaptation identifies many factors, but describes few processes whereby adaptation is constrained or may indeed fail to avoid catastrophic losses. It often assumes that barriers are by and large distinct from limits to adaptation. We respond to recent calls for comparative studies that are able to further knowledge about the underlying drivers of barriers and limits to adaptation. We compare six cases from across Australia, including those in alpine areas, rivers, reefs, wetlands, small inland communities, and islands, with the aim of identifying common underlying drivers of barriers and limits to adaptation. We find that the path-dependent nature of the institutions that govern natural resources and... |
