Краткое описание

It has been experimentally found that the simultaneous effect of several external factors, such as light, temperature and electrical field of photomovement parameters (translational velocity and photoorientation) of two species of Dunaliella Teod. (D. salina Teod., and D. viridis Teod.) has a complex non-linear and cooperative character. Analysis of experimental data according to a linear regression model allowed us to recognize that the studied Dunaliella species differ essentially by their motile behavior depending on the effect of the above factors and their combinations. It explains distinctions in ecology of these species under natural conditions.
