“…It also relates to some of the results, which in the framework of this work can be considered as side results. It is about the above-mentioned results [13, 14, 18] of mathematical modeling of the structure and dynamics of some plant communities (i. e., communities of photosynthetic organisms.) Mass reproduction of toxic cyanobacteria observed quite recently in the Baltic sea is a resonant example of the threat to biosafety associated with such communities.…”

“…As such situations are possible, the methods of image processing based on the results presented in [13, 14] will be required. They will help to establish the boundaries of accumulations of toxic cyanobacteria in water areas [13] and their areas most vulnerable to certain types of air processing [14].…”

“…In [15,18,19,20,21], abilities to use the differences between the background's ITS and the animals' IPTS in the methods of image processing for improving the detection conditions on the ground are shown. In [22], such abilities based on the results of comparisons of relationships' graphs between color parameters of PCA and the plant background constructed by DMDS are shown.…”

“…Below, the results that illustrate possibilities of a formalized description of ASs of the effect of PCA based on the precedents of using the data with such lacks are described. It is about the results presented in [13, 14, 15] on a formalized description of the CPs’ dynamics for relatively simple plant communities. These results were obtained by using advanced mathematical models [16, 17]–Discrete Models of Dynamical Systems (DMDS).…”

This study aims to investigate the relationship between the diversity and uniformity of the protective coloration of animals. The protective coloration of animals is the result of the formation of adaptation strategies. The aim of this study is to identify the colorimetric parameters that characterize the adaptive properties of the protective coloration of animals in relation to their natural habitat. The relevance of this study is related to the importance of the tasks of remote collection of information about various biological species; in particular, animals that carry dangerous infections. This is all the more important in light of the current epidemic problems facing humanity. The revealed colorimetric characteristics can be used to describe digital images and their further recognition. They can be classifying features in machine learning algorithms. We give an example of digital image processing of a duck (Anas platyrhynchos). The analysis of the distribution of the found colorimetric parameter makes it possible to identify the image segments corresponding to the Anas platyrhynchos. The results thus obtained are also of interest from the point of view of the problem of the adaptive role of the diversity of biological systems in relation to the problem of the mechanisms of functioning of the protective coloration of animals.

Methods for identification of potentially radon-prone areas using geospatial analysis in ArcGIS 10.6 software environment and mathematical modeling in SPSS 19.0 on the example of high background radiation area have been developed. High level of natural radioactivity associated with uranium content in environment objects and natural uranium occurrences, and also the spatial density of faults (reliable and unreliable) and lineaments were taken into account as well as the distance from uranium mine located nearby. The method of linear discriminant functions was used to make a math model for determining the level of radon hazard. To do this, data on all locations were divided into training and test samples. Determination of predictors of the mathematical model was performed using Fisher's criterion by their sequential inclusion in discriminant equations. Among the considered 13 factors of radon hazard, seven of them turned out to be informative. For them, canonical coefficients were calculated using the least squares method for first- and second-order polynomials. Based on the values of discriminant functions, a territorial map was constructed to assign the new location to a certain level of radon hazard. The maps obtained present the correlation of the radon-prone areas with the zones of high spatial density of faults and lineaments, and confirmed by the data of direct indoor radon measurements. In a limited number of measurements, the methods might get a good help in prioritization for round-the-country radon survey. As far as the model for identification of potentially radon-prone areas is mainly based on geological studies, the further research is supposed to be directed to its approbation for a different geological environment of the Ukrainian shield.
