摘要: An attempt is made to provide some unifying principles in ecology. The structure of ecosystems considered relation various components, with emphasis on the characteristics maturity as measured by diversity data and other determinable features, including primary production (P) biomass (B). Ecosystems complex containing a high amount information can be maintained relatively lower expenditure energy. Oscillations, introduced for example environmental changes or outside exploration, tend retain an ecosystem state maturity. Where succession occurring, involving exchange excess available energy future increase biomass, relations encountered may applied not only successive states same system; but adjoining coupled subsystems. Steepness gradient between subsystems shown depend several factors subject quantitative determination these imitated ...
