The main function of the photosynthetic leaf is to convert light energy into chemical energy and to assimilate CO 2 . Coordination of these functions as related to the heterogeneous leaf structure and the distribution of metabolism within the leaf has been investigated in many studies [1–5, etc.]. Presumably, after hundreds of millions of years of(More)
The localization of the key photoreductive and oxidative processes and some stress-protective reactions within leaves of mesophytic C3 plants were investigated. The role of light in determining the profile of Rubisco, glutamate oxaloacetate transaminase, catalase, fumarase, and cytochrome-c-oxidase across spinach leaves was examined by exposing leaves to(More)
Methodological bases of optimization modeling approach are considered in regard to describing critical phenomena in forest ecosystems. Models of insects’ outbreaks, forest successions, forest fires as second order phase transitions are proposed. It is shown that there is fair correlation between model calculations and observations data.
The population dynamics of gypsy moths from different habitats of the southern Urals was analyzed. Patterns of cyclic changes in the population density were examined. The conjugation of the time series of gypsy moth population dynamics from different habitats at the territory of the southern Urals was assessed. Relationships between the population density(More)
A model of ecological second-order transitions has been proposed as a description of altitude-belt zonality of wood vegetation. The objects of the study are forest cenoses on the northern slope of Kulumyss Ridge (the Sayan Mauntains), while the results include the altitude profiles of forest vegetation. Ecological phase transition can be considered as a(More)
For a description of the successional processes in forest coenoses and the spatial distribution of tree species, an approach using phase transitions models is proposed. We introduced a variable equation and phase transition models that describe processes in forest coenoses. The analysis showed that the model considering processes in the forest as(More)
The abundance dynamics of different populations with the bordered white Bupalus piniarius L. has been analyzed. It has been demonstrated that the populations of B. piniarius in different habitats at the territory of Europe and the Asian part of Russia have cyclic oscillations in their density when in a stable-sparse state. A mathematical model describing(More)
Methods for assessing the primary productivity of the forest stands between various tree species in different environmental conditions are considered. Methods for the primary productivity assessment using data on the phytomass fractions and stand wood stock have been proposed. It is shown that the Zipf-Pareto equation of the relationship between the(More)
The current classification of interactions between species in an ecosystem is based on the Lotka–Volterra model. Depending on the sign of the term characterizing the interaction between species, and taking into account the symmetry of the equations used in the model, six types of interaction are usually distinguished: competition, predatoriness or(More)
The paper deals with an approach to the description of the age and temporal dynamics of cancer, based on the model describing the dynamics of the age of cancer as a second order phase transition. This approach is widely used for studying physical systems. This model of cancer development as second order phase transitions is in a good agreement with medical(More)
