Fragmentation and flow regulation of the world's large river systems
Christer Nilsson,Christer Nilsson,Catherine A. Reidy,Catherine A. Reidy,Mats Dynesius,Mats Dynesius,Carmen Revenga,Carmen Revenga +7 more
TL;DR: A global overview of dam-based impacts on large river systems shows that over half (172 out of 292) are affected by dams, including the eight most biogeographically diverse catchments, which can be used to identify ecological risks associated with further impacts onLarge river systems.
Journal ArticleDOI
Fragmentation and flow regulation of river systems in the northern third of the world.
Mats Dynesius,Christer Nilsson +1 more
TL;DR: To improve the conservation of biodiversity and the sustainable use of biological resources, immediate action is called for to create an international preservation network of free-flowing river systems and to rehabilitate exploited rivers in areas that lack unaffected watercourses.
Journal ArticleDOI

TL;DR: Despite the recognized importance of reservoirs and dams, global datasets describing their characteristics and geographical distribution are largely incomplete as mentioned in this paper, which makes it difficult to perform advanced assessments of dams and reservoirs.

TL;DR: A comprehensive assessment of the world’s rivers and their connectivity shows that only 37 per cent of rivers longer than 1,000 kilometres remain free-flowing over their entire length.
Journal ArticleDOI
Reducing redundancy in invasion ecology by integrating hypotheses into a single theoretical framework
TL;DR: It is argued that a top-down approach that focuses on PAB maximizes research efficiency and identifies the most influential factors first, and subsequently narrows the number of potential causal mechanisms.
