Main research areas:
A new approach to the classification of reactions of the eukaryotic organisms to salinity. 2001-2003. The aquatic organisms were classified into ecological groups in relation to salinity based on personal and literature data. The groups are applicable to single-celled and multicellular organisms. As a criterion for separation of groups we proposed an original method based on the analysis of the tolerant polygons and the type of osmoregulation. We formulated the criteria for inclusion of organisms into the ecological groups. We studied the salinity tolerance and constructed salinity tolerance ranges for 15 species of ciliates, 5 species of lobose amoebae (S.A. Smurov), and 4 species of multicellular marine organisms (A.Y.Komendantov). In the several studied species of unicellular and multicellular organisms we described species-specific salinity tolerance polygons and limits of the tolerance range. We shown that the potential tolerance and salinity tolerance range are stable characteristic of the species. The changes of these characteristics in the media with an ionic composition different from the ocean water are predictable and resemble the processes in the sea water. We developed and tested a new method that helps to use the data about reactions to salinity of the medium in phylogenetic reconstructions. In the course of the project we analyzed personal and literature data about the reactions of the estuarine multicellular species to salinity. The results of the analysis were presented in the monograph by A.Y. Komendantov and M.I. Orlova, "Ecology of clams and polychaetes of South Primorye.

The rate of function and resistance adaptation and adaptation of aquatic invertebrates to salinity. 2004-2006. Our results show that the duration of the resistance adaptation in marine invertebrate animals is usually less than the duration of the function adaptation, the maximum completion time of the latter may exceed 4 weeks. Our results shown that the duration of the resistance adaptation to new salinity in freshwater and euryhaline protists was 18-24 hours, which was significantly less than the duration of the resistance adaptation in marine multicellular organisms. A.O. Smurov proposed a mathematical model describing the dynamics of the of function adaptation, depending on the acclimation salinity, the magnitide of the changes in salinity within the tolerance range and time of acclimation. The rate of function adaptation of marine organisms to new salinity within the tolerance range is well described by the model of von Bertalanffy. It was shown that the choice of the response function is important when estimating the rate and duration of the acclimation for the organisms with decreasing ability of isolation from the influence of salinity of the external environment (molluscs: Hydrobia ulvae - Littorina obtusata - Hiatella arctica). The recovery of mobility and feeding activity took more than 14 days for Hydrobia ulvae and not more than 1 day in Hiatella arctica. Therefore, it is necessary to use other response function, such as heart rate, to assess the rate and duration of adaptation for organisms that do not possess the ability to isolate from the influence of salinity. Our experiments have shown that tissues of marine organisms can adapt to changes in environmental salinity during the day. At the same time it took up to 10-14 days for an intact organism to adapt to the same salinity, when evaluating the same parameters, besides the tissue adaptation and the adaptation of the whole organism could go in different directions. Our results shown that the duration of the resistance adaptation to new salinity in freshwater and euryhaline Paramecia was 18-24 hours, which is significantly less than the duration of the resistance adaptation in marine multicellular organisms.
