\subsection{Homeostasis}  The homeostasis \textit{h} calculation by comparing the daily values of all variables is a useful indicator for periodic or seasonal dynamics characterization and determination. \textit{h} can represents the temporal variation of the state of each subsystem in each lake. This situation is more evident in the Physico-chemical subsystem of lakes which responds proportionally with the seasonal changes affecting variables like temperature, light and others relate related  with the hydrological cycle. Limiting Nutrient subsystems works in a larger scale than Physico-chemical subsystem; it seems that nutrients could vary more at week scales than day scales. For all three subsystems, biomass demonstrated has the largest scale variation; in special at the T which their biomass variation takes place in several months intervals. The above homeostasis results demonstrates the importance of the temporal timescale because \textit{h} can vary considerably if we compare states every minute or every month. For \textit{H}, the table ** relates the shows  mean values and standard deviation for all lakes and subsystems. Consideringthat  the lakes studied maintains periods without changes, values of H are all in the category of very-high homeostasis. We observe that Biomass and Physico-chemical were more stablesystems  in a year than Limiting Nutrients subsystem. In detail by the lake at detail,  the Ar and NL Biomass is were  more regular regulars  than NL and T. Physico-chemical subsystem have a similar regularity for all lakes being the lower NL. For Limiting Nutrients, the lower regularity is also for  NL and the high for Ar.
