Collecting streaming services
No full textIn the streaming era, the very thing that defines it is what threatens toimpede access to important media history and cultural heritage.Streaming’s barriers to entry and its interim content catalogs challenge the actual collection and preservation of it for research and teaching purposes. If researchers and libraries do not work together to document and preserve these, we will keep losing important sources and data. From a collection perspective, we argue that streaming services consist of their catalog, metadata, andgraphical user interfaces. First, we map the large-scale legal deposit collection of streaming at a national library as well as a media researcher’s small-scale targeted collection. Second, we compare the resulting collections of web sites and graphical user interfaces in order to discuss methodological challenges. The findings of this comparative analysis indicate the existing deficiencies in both collections and suggest potential improvements in the collection andpreservation of streaming services
No Future Growth Enhancement Expected at the Northern Edge for European Beech due to Continued Water Limitation
No full textABSTRACT With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts on tree growth, vitality, and survival. How individual tree species will react to increased drought stress is therefore a key research question to address for carbon accounting and the development of climate change mitigation strategies. Recent tree-ring studies have shown that trees at higher latitudes will benefit from warmer temperatures, yet this is likely highly species-dependent and less well-known for more temperate tree species. Using a unique pan-European tree-ring network of 26,430 European beech (Fagus sylvatica L.) trees from 2118 sites, we applied a linear mixed-effects modeling framework to (i) explain variation in climate-dependent growth and (ii) project growth for the near future (2021?2050) across the entire distribution of beech. We modeled the spatial pattern of radial growth responses to annually varying climate as a function of mean climate conditions (mean annual temperature, mean annual climatic water balance, and continentality). Over the calibration period (1952?2011), the model yielded high regional explanatory power (R2?=?0.38?0.72). Considering a moderate climate change scenario (CMIP6 SSP2-4.5), beech growth is projected to decrease in the future across most of its distribution range. In particular, projected growth decreases by 12%?18% (interquartile range) in northwestern Central Europe and by 11%?21% in the Mediterranean region. In contrast, climate-driven growth increases are limited to around 13% of the current occurrence, where the historical mean annual temperature was below ~6°C. More specifically, the model predicts a 3%?24% growth increase in the high-elevation clusters of the Alps and Carpathian Arc. Notably, we find little potential for future growth increases (?10 to +2%) at the poleward leading edge in southern Scandinavia. Because in this region beech growth is found to be primarily water-limited, a northward shift in its distributional range will be constrained by water availability.With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts on tree growth, vitality, and survival.

No full textBy way of water’s role in urban space, the chapter will revisit the notion of hybrids from two points: first, these ideas of hybridity in themselves reconstructed the binaries they set out to eradicate, and second, if the distributed agency that followed hybrid thinking actually eroded the notion of agency as a relational term. The discussion will be based on a case of spatial practices of water in a century of Copenhagen’s history—trams, plumbers, bathing halls, and bathrooms, respectively—and the processes through which they contribute to urban transformation. Following these changes, the concept of ‘phronologies’ is proposed as a hybrid approach that might counter the abovementioned issues, while still being in a state of conceptual development itself
