In ecological terms, the dynamics observed at NL point in the transect Ar-T could be estimates as a complexity ecotone or “complextone”(tone, from the Greek tonos or tension). That means that NL point could be considered as a “physical transition zone” for complexity values among lakes in a latitudinal gradient. Consequently for some variables therein subsystems it is estimates that it could be to represents diverse complexity ecoclines or “complexcline” (cline from Greek: κλίνω "to possess or exhibit gradient, to lean"), due their complexity variation. For example for biomass, we can that there is a biocline in the transect Ar-T and in particular for cyanobacteria at the planktonic zone (PCy) we can name a complex cyanocline.  From PCA ordination from variables of all subsystems conducts to the conformation of groups of lakes based on emergence, self-organization, complexity and autopoiesis properties. However, we chose the complexity criteria for definition of groups due to complexity relates the regularity and changing aspects, and it is the base for autopoiesis calculation. This way, the general ordination shows the NL disjoins of the group conforming by NH-Ar with T. The separation of NL from other lakes is by cause of the variability and load of some variables of biomass and Physico-chemical subsystem. These variables were macrophytes, clorophyceas and planktonic phosphorous and by the low level in complexity of the fishes and light variables. NL separation also supports the consideration that NL represents a transition in the values for all properties, marking this location as differential on the latitudinal gradient from the arctic to tropic.  \subsection{Autopoiesis}  In terms of autopoiesis, the autonomy of the biomass at the tropic demonstrates that this subsystem could be affected in major proportions in case of climatic change events.
