    European Islands Between Isolated and Interconnected Life Worlds: Interdisciplinary Long-Term Perspectives

    Get PDF
    Island studies have seen an upswing in recent years. Whereas in the past, research was largely oriented at external perspectives and perceptions, at present we witness an increasing interest in viewpoints internal to the island societies examined (with an ‘inside-out’ approach). This volume contributes to such efforts with transdisciplinary and methodological reflections from the fields of archaeology, ethnology, geography, history, philology, and literary studies. Focused on the interplay between geographic isolation and commercial as well as cultural connection, the studies here assembled investigate the role of the knowledge, resources, and practices of islanders in processes of crisis management, identity formation and transformation

    Towards Eco-Centric Interaction: Urban Playful Interventions in the Anthropocene

    The twin crises of nature and climate is supported by overwhelming scientific evidence and increasing public concern about long-term and potentially irreversible consequences of the Anthropocene. People and wildlife living today, as well as future generations, are at risk unless urgent action is taken to reverse the loss of plants, insects and other creatures on which we depend for food, clean water, and a stable climate. As urban dwellings become the main concentration of citizens, we thought of addressing these issues through a series of urban interventions aiming at educating and enhancing the user\u2019s biodiversity and sustainability awareness through play and reflection. We provide a list of preliminary insights, discussed, and shared trying to frame how these new interventions can contribute to a panorama where playful interactions in smart cities can inspire sustainable and respectful attitudes towards nature. We conclude with a constructive conversation about playful urban approaches aimed at understanding how the interaction process could be re-centered to promote environmental protection and ecological consciousness on the part of technology users. Our case studies strive to reconcile concepts and theories, about ecological computing, more than human design, biodiversity actions and nature awareness and conservation in urban settings, for the design of urban playful and enjoyable systems that promote environmental protection and ecological consciousness on the part of technology users

    Climatic controls of decomposition drive the global biogeography of forest-tree symbioses

    The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools 1,2 , sequester carbon 3,4 and withstand the effects of climate change 5,6 . Characterizing the global distribution of these symbioses and identifying the factors that control this distribution are thus integral to understanding the present and future functioning of forest ecosystems. Here we generate a spatially explicit global map of the symbiotic status of forests, using a database of over 1.1 million forest inventory plots that collectively contain over 28,000 tree species. Our analyses indicate that climate variables—in particular, climatically controlled variation in the rate of decomposition—are the primary drivers of the global distribution of major symbioses. We estimate that ectomycorrhizal trees, which represent only 2% of all plant species 7 , constitute approximately 60% of tree stems on Earth. Ectomycorrhizal symbiosis dominates forests in which seasonally cold and dry climates inhibit decomposition, and is the predominant form of symbiosis at high latitudes and elevation. By contrast, arbuscular mycorrhizal trees dominate in aseasonal, warm tropical forests, and occur with ectomycorrhizal trees in temperate biomes in which seasonally warm-and-wet climates enhance decomposition. Continental transitions between forests dominated by ectomycorrhizal or arbuscular mycorrhizal trees occur relatively abruptly along climate-driven decomposition gradients; these transitions are probably caused by positive feedback effects between plants and microorganisms. Symbiotic nitrogen fixers—which are insensitive to climatic controls on decomposition (compared with mycorrhizal fungi)—are most abundant in arid biomes with alkaline soils and high maximum temperatures. The climatically driven global symbiosis gradient that we document provides a spatially explicit quantitative understanding of microbial symbioses at the global scale, and demonstrates the critical role of microbial mutualisms in shaping the distribution of plant species

    BioTIME:a database of biodiversity time series for the Anthropocene

    No full text
    Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene.Main types of variables included: The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of two, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology andcontextual information about each record.Spatial location and grain: BioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km2 (158 cm2) to 100 km2 (1 000 000 000 000 cm2).Time period and grain: BioTIME records span from 1874 to 2016. The minimum temporal grain across all datasets in BioTIME is year.Major taxa and level of measurement: BioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton, and terrestrial invertebrates to small and large vertebrates.Software format: .csv and .SQ
