[The systemic-functional analysis of the principles of organization of vertebrate behavior]. / Sistemno-funktsional'nyi analiz printsipov organizatsii povedeniia pozvonochnykh.

The classification of systemic principles in animals' behaviour organization is revealed and based by means of functional triad method. The methodical basis for structure and function relationship in behaviour formation is given.

[Adaptive reactions of algal populations to exposure to toxic substances]. / Adaptivnye reaktsii populiatsii vodoroslei na vozdeistvie toksicheskikh veshchestv.

The adaptative reactions of alga populations to the toxic effect have been investigated by the functional triad method. The role of phenotypic and genotypic adaptation and the dynamics of their correlation during the alga adaptation to the toxic media has been revealed.

[Pigmentation of the outer cornea after removal of the eye from Rana lessonae Camerano larvae]. / Pigmentatsiia naruzhnoi rogovitsy posle udaleniia glaza u lichinok Rana lessonae Camerano.

Dynamics and morphological peculiarities of pigmentation in the external cornea after removal of the eye in larvae of Rana lessonae Camerano have been studied in situ depending on the developmental stage during prometamorphosis. The results are compared with the previously obtained data for tadpoles of Rana temporaria (D. V. Popov, Sokolova Z. A., Kalistratova E. N. et al., 1982). The process of pigmentation in the cornea does not depend on the developmental stage, proceeds with a constant rate and accomplishes before the beginning of the metamorphous climax. In the Rana lessonae tadpoles the dermal chromatomorphous units differentiate earlier than in the Rana temporaria larvae. The period of metamorphosis in the R. lessonae is 2 times as long as in the R. temporaria. At the same time, transplantation of the epidermal melanophores during the process of the cornea pigmentation in these species is realized with the same rate. Thus, in this case, the phenomena occurring at the cellular and organism levels are rather autonomous. The differences revealed between the cornea pigmentation in the R. lessonae and R. temporaria larvae are explained as the phenomenon of interlevel heterochrony in ontogenesis.
