TL;DR: Biological systems are considered that are capable of dynamic self-organization, i.e., spontaneous emergence of spatio-temporal order with the formation of various spatio -temporal patterns.
Abstract: Biological systems are considered that are capable of dynamic self-organization, i.e., spontaneous emergence of spatio-temporal order with the formation of various spatio-temporal patterns. A cell is involved in the organization of ontogenesis of all stages. Embryonic cells exhibit coordinated social behavior and generate ordered morphological patterns displaying variability and equifinality of development. Physical and topological patterns are essential for biological systems as an imperative that restricts and directs biological morphogenesis. Biological self-organization is directed and fixed by natural selection during which selection of the most sustainable, flexible, modular systems capable of adaptive self-organization occurs.

TL;DR: Stable isotope ecology and patterns of stable isotope fractionation during organic matter decomposition are considered with special emphasis on the fractionation of isotopes in food chains and the use ofstable isotope studies of trophic relationships between soil animals in the field.
Abstract: The development of stable isotope techniques is one of the main methodological advances in ecology of the last decades of the 20th century. Many biogeochemical processes are accompanied by changes in the ratio between stable isotopes of carbon and nitrogen (12C/13C and 14N/15N), which allows different ecosystem components and different ecosystems to be distinguished by their isotopic composition. Analysis of isotopic composition makes it possible to trace matter and energy flows through biological systems and to evaluate the rate of many ecological processes. The main concepts and methods of stable isotope ecology and patterns of stable isotope fractionation during organic matter decomposition are considered with special emphasis on the fractionation of isotopes in food chains and the use of stable isotope studies of trophic relationships between soil animals in the field.

TL;DR: The effect of flow turbulence on the swimming speed was studied in perch (Perca fluviatilis) with different body length and the critical flow rate was used as an index of fish swimming performance.
Abstract: The effect of flow turbulence on the swimming speed was studied in perch (Perca fluviatilis) with different body length. The critical flow rate was used as an index of fish swimming performance. The longer was the fish, the higher turbulence was required to decrease the critical flow rate. The mechanism of turbulence impact on fish locomotion relied on the vortex structure of the flow. The torque produced by hydrodynamic forces in a vortex favors fish overturn and loss of balance. Such effect of turbulence was observed when the sizes of the vortex and fish body were similar. The fish uses the pectoral fins to restore the balance, which increases their hydraulic resistance and, together with energy expenditure for spatial balance control, decreases the swimming speed.

TL;DR: Special attention is given to the emergence and phylogenetic development of the lymphocyte, the key component of immune response, as well as to the evolutionary development of T- and B-cell immune systems, adaptive immune responses and their molecular regulators (cytokines), and antigen-recognition structures.
Abstract: The current state of the problem of emergence and evolution of adaptive immunity in different taxonomic groups of animals is analyzed. Special attention is given to the emergence and phylogenetic development of the lymphocyte, the key component of immune response, as well as to the evolutionary development of T- and B-cell immune systems, adaptive immune responses and their molecular regulators (cytokines), and antigen-recognition structures.

TL;DR: Fungal infection of insects increases total esterase and glutathione S-transferase activities in the hemolymph and increases the resistance of greater wax moth caterpillars to organophosphorus insecticide malathion 1.46 times relative to intact caterpillar.
Abstract: Fungal infection of insects increases total esterase and glutathione S-transferase activities in the hemolymph. Activities of acid and alkaline phosphatases were similar in the infected and intact insects. Fungal infection increased the resistance of greater wax moth caterpillars to organophosphorus insecticide malathion 1.46 times relative to intact caterpillars. Possible involvement of detoxification enzymes in the development of insect resistance to entomopathogenic fungi and development of complex biological products based on ento- mopathogenic microorganisms and inhibitors of detoxification enzymes are discussed.
