River rehabilitation decisions, like other decisions in environmental management, are often taken by authorities without sufficient transparency about how different goals, outcomes, and concerns were considered during the decision making process. This can lead to lack of acceptance or even opposition by stakeholders. In this paper, a concept is outlined for(More)
Human population growth, economic development, climate change, and the need to close the electricity access gap have stimulated the search for new sources of renewable energy. In response to this need, major new initiatives in hydropower development are now under way. At least 3,700 major dams, each with a capacity of more than 1 MW, are either planned or(More)
14 and Daniel Tsegai 15 Human water security is often achieved with little consideration of environmental consequences and, even when these are acknowledged, the trade-offs between human and environmental water needs are increasing in frequency and amplitude on the increase. The environmental flows concept has continued to evolve in response to these(More)
1080 POLICYFORUM A proposed ruling by the U.S. Environmental Protection Agency (EPA), aimed at clarifying which bodies of water that fl ow intermittently are protected under law (1), has provoked confl ict between developers and environmental advocates. Some argue that temporary streams and rivers , defi ned as waterways that cease to fl ow at some points(More)
Understanding individual space use remains a major issue in ecology, and it is complicated by definitions of spatial scale and the interplay of multiple factors. We quantified the effect of habitat and biotic and individual factors on space use by amphibians (Bufo bufo spinosus [BB] and Bufo viridis [BV]) that were radio-tracked in their terrestrial summer(More)
Differential habitat selection is a central component in the evolution of species, but it has been quantified rarely for sympatric species in relation to the multiple impacts of resources at the spatial scales at which animals operate. Our main goal was to quantify the selection of terrestrial summer habitats in a natural floodplain in Italy by two(More)
River floodplains are among the most threatened ecosystems globally. Understanding the mechanisms that create and maintain biodiversity and ecosystem functioning of floodplains, is therefore a prerequisite for developing scientifically-sound management and conservation strategies. We quantified the spatial distribution of lateral aquatic habitats (i.e.(More)
Quantifying spatial and temporal dynamics of organic matter (OM) is critical both for understanding ecosystem functioning and for predicting impacts of landscape change. To determine the influence of different habitats and coarse particulate OM (CPOM) types upon floodplain OM dynamics, we quantified aerial input, lateral surface transfer, and surface(More)
(2015) Biodiversity research: data without theory—theory without data. Policy support and biodiversity assessment Meet two famous researchers from the early days of biodiversity research: Charles Darwin and Alexander von Humboldt. Darwin developed a powerful theory, using a limited amount of data by modern standards. Humboldt, in contrast, compiled a "(More)
