\subsection{Complexity as the Balance Between Emergence and Self-organization}  \subsubsection{General view \subsubsection{Complexity in the Physico-chemical Subsystem}     At the Arctic Lake (Ar) variables related with light (SL, PL and BL) have high value of emergence, while BCd and ZM have very high self-organization. Remaining variables were classified in very high complexity category, with the exception of two variables associated with inflow and benthic conductivity (ICd and BCd) ranking in very low (Annex **).     At the North Highland Lake (NH), light variables increase their change ranking to very high emergence category; in consequence its complexity is reduced to low and very low categories. BCd and Zm variables increase its complexity to high category.     At the North Lowland Lake (NL) temperature variables increases its level of change to very high as light variables. Remaining variables had fair to very high emergence. Thus, self-organization, in general was low. As the result of the above facts, variables with very high complexity were relating with hydrology (IO, RT) conductivity (ICd, PCd) and pH in all zones of lake.     At the Tropical Lake (T), all physiochemical variables have similar levels of regularity (S) and change (E); consequently majority of variables have high or very high complexity with the exception  of Physiochemical, ZM and SdO2.     As generalization based on PCA ordination we can say that variables of physiochemical subsystem can conform 3 groups related to properties of E, S,C,A (Fig. **). Group 1 Variables related with high changes or emergence related with light. Group 2: variables related with high regularity like Conductivity and Zone Mixing. Group 3 Variables expressing high complexity Temperatures, Oxygen,pHs, RT and Inflow and Outflow. With these variables, the system respond to the change….     \subsubsection{Complexity in the Limiting  Nutrient Limitans Subsystem}     Arctic high E Inflow Silicates, Carbon Dioxide at Inflow and Planktonic Zones. Very High S- Nitrogen at 3 layers, high silicates phosporous in plankctonic and bencthic Zone. Also, Planktonic detritus. In complexity terms very high IS, PP,BP, CCD, Detritus.     NH Carbon Dioxide in very high S(Planktonic) and hig (Inflow and C). siliciates in Planktonic and Benthic zone, Nitrogen and Phosphorous in 3 layers (nitrogen in benthic was high S). very high Complex variables IS (due high E and low S), Carbon Dioxide in Inflow and C, and detritus.     Due an increasing in the emergence of nitrogen and decreasing in the S of detritus 13 of the 16 variables of the limiting nutrient components was classified in very high and high complexity categories. Variables that no reach the above level were due to their very high emergence like Carbon Dioxide in planktonic and C, and Benthic detritus. At this point of the gradient Ar-T complexity has an important variation that continuous its increment of the balance between emergence  and self-organization at the end of the gradient. This way in tropic very high levels of complexity for the majority of variables are shown. Only the very high emergence of detritus were the exception. In consequence in the tropic limiting nutrients in general have positive autopoiesis defining more autonomy for adaptation.     In gradient Ar-T there are an increasing of very high complexity category for all variables, only IS having high complexity due to high emergence.     From PCA ordination, the groups that can be identified are Group representing emergence: Detritus, Carbon Dioxide. Group representing self-organization Nitrogen and Inflow Phosphorous. Group representing complexity Silicates and Phosphorous in Planktonic and Benthic zone.     \subsubsection{Complexity in  Biomass Subsystems (including Factor Analisis Synthesis)} Subsystem}     At the Arctic self-organization for all groups of phyto and zooplankton species in all zones, are high or very high. Only the low emergences of Diatoms, Cyanobacteria and Green Algae permits that these photosynthetic organisms reach very high levels of complexity and autopoiesis. This situation continuing in NH in spite of the planktonic diatom and cyanobacteria reach fair category of emergence. It means, the feature of this two types of lakes is your regularity.     In a similar way that with limiting nutrient subsystem when the gradient reach NL dynamics of emergence and self-organization varies in considerable level. Here, the complexity of almost all variables were maximum due the balance in self-organization and emergence reached. Only, Chlorophiceas, Benthic detritus and Fishes in Planktonic and Benthic Zone have regularity all annual cycle     In contrast to the NL, the biomass subsystem in the tropic reflects very low complexity due the very high self-organization of the living taxa. Only planktonic and piscivorous fishes reached very high and high complexity, respectively.     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.     From PCA ordination, it can be seen that photosynthetic taxa of planktonic and benthonic zone are more emergent and macrophytes. Consumers primaries and secondaries of the plankton in addition with clorophiceas and BDt are more self-organized and Piscivorous and Planktivorous fishes are more complex. The last passively due to…  \subsubsection{Complexity in Latitudinal Gradient}
