Ascendency redundancy and development capacity

Information theory is employed to quantify how well "organized" the trophic web is (expressed in terms of an index called the system's "ascendency"), how much functional redundancy it possesses (what is termed the "overhead"), what its potential for development is, and how much of its autonomy is encumbered by the necessary exchanges with the external world (Ulanowicz and Kay, 1991).

According to the "total system throughput (TST)", the graminoid system is far more active than the cypress system (Table 9.4). Its TST (10,978 gCm"2 per year) is fourfold that of the cypress system (2952 gCm"2 per year). The development capacity of an
