Study of biocomplexity in an aquatic ecosystem through ascendency.

摘要: The ascendancy concept aims at quantitatively describing the growth and development of an ecosystem as whole. Growth is increase in total system throughflow, while taken to be a rise average mutual information inherent network flow structure. As matures goes through series successional stages, its exhibits propensity increase. In any equilibrium condition may gradually turn into chaotic situation for different reasons. this paper model proposed aquatic comprising three groups, viz., phytoplankton, zooplankton fish. Rate parameters are changed according change size organisms. run conditions with gradual decrement body sizes zooplankton. Allometric principle relationship two rate (growth half saturation constant) incorporated model. According allometric consequently increases grazing decreases half-saturation constant states (equilibrium point--stable limit cycle--doubling ultimately chaos) by decrease constant. This tests high level systems edge oscillation before starting chaos. throughflow information, i.e. Ascendency supports hypothesis that can coordinate most complex behavior shows maximum biocomplexity situation.
