It was shown that the main morphological functional adaptations in evolution of the organ of hearing were the adaptations, directed to optimization of auditory sensitivity in various environments.
Vibrissa differs markedly from the hair in its structure and, possibly, has originated from mechanoreceptors of ancient forms (cotylosaurus developing only in the branch, represented by recent species of marsupials and placental mammals.
On the basis of hair polymorphism (more than 300 species were studied) and feathers (80 species) it was determined that fine structure of the basic structures (cuticle, cortex, and medullae) of the hair and feather was similar in these phylogenetically separated classes.
In the cornea cells of rooks in the zone with maximal degree of pollution,.5 times more mutations appeared compared to non-polluted region.For the first time it was shown that pathology of the muscular system of fishes included also the development of degenerative changes in corresponding parts of their nervous system, affecting both motor and sensory innervation of the muscles.General patterns and peculiarities of embryonic development and structure of stomach chambers in phylogenetically close species of the subfamily Caprinae (Bovidae, Artiodactyla) were revealed at bon de reduction gallia calisma 1er age all levels of structural organization in connection with their food specialization including the species with a shared areal (saiga, Kalmyk.Convergence in hair and feather structure was soluble at the functional basis: execution of similar functions (heat-insulation one in this case) determined creation of the structures with similar design in coordination with other organs and mechanical limitations.
Laser irradiation of low intensity (lili) influences the processes of secondary histogenesis of skeleton muscular tissue, going in different conditions (local irradiation of the muscles and total irradiation of the organism).
It was determined that topography, structure and function of cutaneous glands of mammals, as derivatives of integument, reflected the patterns of evolution and adaptive radiation of taxa, serving as criteria of taxonomic status and adaptation of the species and living forms to environment.
General patterns of development of the organ of hearing and equilibrium were determined in mammals in pre- and postnatal ontogenesis.
In summer period in fishes and amphibians this process went in Kupffer cells with formation of ferritin and hemosiderin.Chernova, main subjects of research: revelation of structural adaptations of the systems of organs and tissues of vertebrates to environmental conditions.A particular position in such investigations belongs to experimental method of the study of such phenomena as recovery of muscles, brain, and liver after different unfavorable influences and diseases (including those of interstellar flight, after the cerebral stroke, laser exposure, immobilization stress etc.).The data about embryonic plumage of birds, besides using in systematics, allowed formation the ideas about the ways of feather evolution.Talpa europaea (staining for fat with sudan black B).It was revealed that the degree of reduction of natal down feathers of birds denoted not relatively longstanding origin of the taxa, but stability of the presence or progress in the loss of this, obviously, atavistic feather plumage in representatives of different taxonomic groups.4) based on the experimental methods, to determine recovery potentials of the tissues and organs, subjected to negative influences of different factors of environment.
For the first time on the basis of functional morphology of stomach chambers, classification according to feeding types of closely related species of Caprinae (highly selective, partially selective and unselective) was presented, allowing to understand the degree of nutritional competition between species with overlapping areals.
