It is known that a mathematical ecological model and, in general, a particu
lar methodology of modelling, can be considered a literary text written in
a formal mathematical language. In this context stylometric mathematical la
ws such as Zipf's (range-frequency and number-frequency) can be applied to
obtain information Parameters in different semantic levels within the same
model. Adapts several of these laws and introduces new elements, lexic unit
s, operating and separating units, to carry out several statistical analyse
s upon two models or texts The estimated slopes in the regression equations
obtained in the present work are compared with the results of previous pap
ers where Mandelbrot's law was applied and comparisons between them are sho
wn.
