This introductory article presents the special Discussion and Debate volume 'From black swans to dragon-kings, is there life beyond power laws?'. We summarize and put in perspective the contributions into three main themes: (i) mechanisms for dragon-kings, (ii) detection of dragon-kings and...

percentage of saturation and pH data show remarkably nice scaling ranges, indicating an important coupling with turbulence, but … reveal the possible influence of environmental factors such as tides and turbulence. Turbidity variability is highly complex … and does not appear to be directly coupled to turbulence, since no clear range is visible. On the other hand, oxygen …

not scale like power laws, as generally assumed. A much improved scaling function is deduced, in analogy with a procedure … first applied to nearest-neighbour dimension estimators. Extremely accurate determination of the scaling exponents is thus … possible. Our refined formula is immediately applicable to the analysis of time series in turbulence, physiology, or economics. …
