The article provides an analysis of the state of knowledge of mycobiota in the context of subjects on the territory of the Russian Caucasus. The regional Red Books were analyzed for the content of rare taxa. The question is raised about the need to train highly qualified personnel in the field of mycology. A review of some publications of mycologists of the North Caucasus and South Federal Districts is made.

The aim is to study the environmental friendliness of long-term work on a computer based on the results of assessing the level of psycho-physiological functions of students with different volumes of training loads using computer technologies in the learning process. Methods: computer analysis of psychomotor reactions, self-assessment and situational anxiety, measurement of heart rate (HR) and blood pressure before and after the local load. 86 volunteer students aged 18-23 years old with a different volume of computer technology in the curriculum were surveyed. The results showed that adaptation to training loads in students with a large amount of computer technology is expressed in a statistically significant increase in indicators such as the speed of simple sensomotor reactions, the rate of complex sensomotor reactions in girls, and a decrease in attention concentration, the rate of selection and discrimination reactions in all subjects. Anxiety rates were higher in students with less computer work. The response of the heart rate to the local load in girls of both groups was more pronounced than in boys. Conclusion. A theoretical statement is formulated about the uneven changes in adaptation processes to study loads in students with a large amount of computer technology, expressed in stimulating certain neurodynamic functions and compensatory reduction of others. The stress of adaptation in girls is more pronounced than in boys. These studies indicate the environmentally unfavorable nature of high computer loads on the body, which manifests itself in functional stress. It is necessary to introduce correctional and recreational activities in the educational process with a large amount of computer technology.

The paper presents the results of the analysis of the use of amphibiontic organisms as bioindicators of the ecological environment, as model groups in ecological engineering. The solution to the conceptual problem of ecological engineering in the conservation of biological diversity is to take an inventory of natural, urbanized and agroecosystems. Among amphibiotic insects, the order Odonata stands out, with morphological plasticity, biological progress, adults and dragonfly larvae actively colonize aquatic and terrestrial ecosystems of various types. When moving to habitat in mountain biotopes, the linear body dimensions of dragonfly larvae of the species L. depressa L., S. meridionale Selys, C. puella L. decrease, which indicates unfavorable, contrastingly changing habitat conditions in mountain ecosystems. The taxonomic composition of dragonflies in lowland water bodies is represented by the suborders Anizoptera (7 species), Zygoptera (5 species), Caloptera (1 species). In the foothill water bodies - Anizoptera (5 species), Zygoptera (4 species), Caloptera (1 species), in mountain water - Anizoptera (4 species), Zygoptera (2 species). Most of the dragonfly taxa are characteristic of the plains and foothills with eutrophied biotopes characteristic of polysaprobic reservoirs with heavy pollution. In oligosaprobic biotopes, with little or no organic pollution in the water, dragonflies Ae. cyanea Müller and C. splendens Harris. The confinement of species to certain habitats, characterized in varying degrees of pollution by organic substances and their oxidation products, makes it possible to use dragonflies as bioindicators and organize background monitoring of ecosystems in the Central Caucasus.
