A text theory of ecological system

In this paper, the authors continue with the development of an ecological m odels theory from the viewpoint of mathematical linguistics. The model is c onsidered as a text, which complies with the text theory (TT) conditions. T he variable transformed functions are defined as symbols, the flow equation s are defined as words, the flow functions or right hand of differential eq uations are defined as sentences, resting on the author particular methodol ogy inspired inspired in the system dynamic illustrated in other papers. Th ree meaning levels are established in each model (text) and the duality sig nificance or explanation (adjustment) and significance or interpretation fo r the observer is defined as getting in the indexes for its indirect measur e. A model interpretation theory is given also.
