Figure 1

Dynamic model used for the analysis. Notation is defined in the Results section and Table 1. Stocks (or compartments, state variables) are shown as boxes, flows as pipes with taps, causal connections (or mathematical dependencies) as arrows, and sources and sinks as clouds (see refs.13, 14). Symbols with dashed outlines are copies (or ‘ghosts’) of the corresponding symbols with solid outlines.
