Stepanyuk Y. Morpho-ecological characteristic of central parts of some mammals’ smelling and optic analyzers

The investigation of central parts of mammals smelling and optic analyzers, which belong not only to different rows (Insectivora, Chiroptera, Rodentia, Primates), but the species, thet belong to different ecologic groups (flying, semiaquatic, underground, semiarborescent, land animals, animals of open space) is carried out. Namely in last ones the influence of environment and ecologic factors on the organization of smelling and optic analyzers’ structures is ascertained. Complex comparison of smelling analyzer’s structures confirms that it is developed by worst. The highest level of organization of smelling analyzers is revealed by insectivorous and underground rodent mole-rat. Optic analyzer among inverstigated species is the best developed by tree shrew. Its links are turned out to be the worst developed by insectivorous, especially by the hedgehod and the mole, though the structures of this analyzer by bicolored shrew have progressive structure characteristics. Among rodents the optic analyzer is developed primively by to a considerable extent – by nutria.
