- This synthesis report is a meta-analysis of perspectives for biodiversity and ecosystems, with a strong focus on human impacts on the environment, and a work order to enable and manage the protection, survival and evolution of all species on Earth. The goal is to protect nature without any further species loss (Zero Extinction). With this report, we assess alarming signals from the environment; determine the needs of threatened biota and the required actions to manage and protect landscapes and ecosystems; and identify some inescapable tendencies, challenges but also possibilities. The story of humans on Earth is at a critical juncture. Human behaviour is inherently dependent on physical and societal relations, including orientation and positioning within the physical environment. There is no single cultural benefit that is independent of provisioning through ecosystem services. Humans are part of the environment, acquire all needs from it and, as such, depend on its integrity and management for life and well-being. Moreover, if human impacts to the environment continue to increase the risk of rebound effects impacting human life and health will increase as well. Whenever a biome, ecosystem, habitat or species is heavily impacted or threatened with irreversible transformation or extinction, prevailing environmental conditions are relevant and should be observed, analysed and remedied as necessary and where possible. Ecology examines the evolutionary, historical and more recent interplay between biological life and the abiotic environment, while the role of social science and the humanities is to question the physical and social landscape, and how and why it should be protected or influenced, e.g. by nature conservation measures under political and economic, ethical and legal considerations. Thus, for all inter-relationships between natural and sociocultural processes, a joint venture in the form of social-ecological thinking is necessary to combine natural sciences and the humanities. With this contribution, we combine ecological knowledge with social science knowledge (s.l.) through the participation of scientists of many different disciplines. We analyse history and current processes to assess risks, threats and possibilities, and call for an array of regulations and measures that can contribute to halting of biodiversity loss and that assist in achieving a sustainable future. Regulations comprise creativity, cultural incentives, social norms, environmental education and economic investments—such as payments for sustainable agriculture, forestry, and fishery; investments in water, soil and air purity; and much clearer and stronger legal restrictions and consequences around waste streams and environmental degradation. Moreover, a gradual change from profit-oriented economies in the short-run to environmentally-sensitive policies that include systematic environmental programmes in the long term might help to decrease pressure on ecosystems and biota. Such economics might also include the real costs of consumerism, including the impacts of particular products on the environment and on human health. The greatest hurdle for the continued existence of many critically endangered species is the impact of widespread anthropogenic-driven change in the usage of water, air and land, and industry intensification in agriculture, aquaculture, forestry, urbanisation, transportation and mining sectors. However, there is not one simple solution to solve these issues. We conclude that many of the current developments have to be adjusted or gradually altered in a step-wise manner, especially with respect to existing sociocultural behaviours. Therefore, various concepts, decisions and measures should be discussed and implemented at all scales from local to supranational and among researchers, practitioners and politicians.

- GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in the Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003). GrassPlot collects plot records (releves) from grasslands and other open habitats of the Palaearctic biogeographic realm. It focuses on precisely delimited plots of eight standard grain sizes (0.0001; 0.001;... 1,000 m(2)) and on nested-plot series with at least four different grain sizes. The usage of GrassPlot is regulated through Bylaws that intend to balance the interests of data contributors and data users. The current version (v. 1.00) contains data for approximately 170,000 plots of different sizes and 2,800 nested-plot series. The key components are richness data and metadata. However, most included datasets also encompass compositional data. About 14,000 plots have near-complete records of terricolous bryophytes and lichens in addition to vascular plants. At present, GrassPlot contains data from 36 countries throughout the Palaearctic, spread across elevational gradients and major grassland types. GrassPlot with its multi-scale and multi-taxon focus complements the larger international vegetationplot databases, such as the European Vegetation Archive (EVA) and the global database " sPlot". Its main aim is to facilitate studies on the scale-and taxon-dependency of biodiversity patterns and drivers along macroecological gradients. GrassPlot is a dynamic database and will expand through new data collection coordinated by the elected Governing Board. We invite researchers with suitable data to join GrassPlot. Researchers with project ideas addressable with GrassPlot data are welcome to submit proposals to the Governing Board.

- BACKGROUND AND PURPOSE: Intracerebral hemorrhage after treatment with intravenous recombinant tissue-type plasminogen activator for ischemic stroke can occur in local relation to the infarct, as well as in brain areas remote from infarcted tissue. We aimed to describe risk factors, 3-month mortality, and functional outcome in patients with the poorly understood complication of remote intracerebral hemorrhage, as well as local intracerebral hemorrhage.METHODS: In this study, 43 494 patients treated with intravenous recombinant tissue-type plasminogen activator, with complete imaging data, were enrolled in the Safe Implementation of Treatments in Stroke-International Stroke Thrombolysis Register (SITS-ISTR) during 2002 to 2011. Baseline data were compared among 970 patients (2.2%) with remote parenchymal hemorrhage (PHr), 2325 (5.3%) with PH, 438 (1.0%) with both PH and PHr, and 39 761 (91.4%) without PH or PHr. Independent risk factors for all hemorrhage types were obtained by multivariate logistic regression.RESULTS: Previous stroke (P=0.023) and higher age (P<0.001) were independently associated with PHr, but not with PH. Atrial fibrillation, computed tomographic hyperdense cerebral artery sign, and elevated blood glucose were associated with PH, but not with PHr. Female sex had a stronger association with PHr than with PH. Functional independence at 3 months was more common in PHr than in PH (34% versus 24%; P<0.001), whereas 3-month mortality was lower (34% versus 39%; P<0.001).CONCLUSIONS: Differences between risk factor profiles indicate an influence of previous vascular pathology in PHr and acute large-vessel occlusion in PH. Additional research is needed on the effect of pre-existing cerebrovascular disease on complications of recanalization therapy in acute ischemic stroke.
