“…To distinguish main trend and rhythmic processes from the time series singular spectrum analysis were used (program "Caterpillar", version 3.40, developed by GistaT Group, Russia). Following options in program "Caterpillar" were: the window length is half of the number of data; without centering [13].…”

“…Thus, cases of weight decreasing can be considered as "negative" growth when dissimilation prevails over the assimilation. The problem of quantitative description of the growth is complicated by the fact that, as a rule, is accompanied by biorhythms, having both exogenous and endogenous nature [12,13].…”

The equation that can describe all known types of animal growth is proposed. The equation contains two basic coefficients, one of which determines the initial rate of growth; the other determines the change of the growth rate. In separate cases two correction coefficients should be taken into account, one of which is connected with morphogenetic processes and the other is connected with spontaneous decrease of the body weight. Biorhythms that accompany growth process can be described by the equation as well. Linear recursive form of the equation allows to use regression analysis and, therefore, comparative intrapopulation, interpopulation and interspecies analysis of growth. Examples of approximation by the equation of own and literature experimental data are shown. Values of the coefficients of the equation for different types of growth in different stages of ontogenesis of the various animal systematic groups are calculated. The equation is suitable to describe change of any biological parameter which is associated with body weight by allometric (power) dependence.

Individual linear growth rates were studied in freshwater pearl mussels Margaritifera margaritifera from the Livojoki River. Growth deceleration coefficients were shown to vary widely and differ significantly among individuals. The average value of the growth deceleration coefficient for the population is 0.060. The growth of mussels in the Livojoki River is accompanied by two regular biorhythms. These biorhythm periods were roughly constant both through an individual's ontogeny and among mussels, their average periods were 7.16 and 4.09 years. We discuss the possibility that these biorhythms are of thermodynamic nature.

Two endogenous biorhythms of the mass specific rate of oxygen consumption with periods of 10.3 and 7.2 weeks have been revealed in the late postlarval ontogenesis of freshwater gastropods Lymnaea stagnalis by singular spectrum analysis. It has been determined that local maxima of both biorhythms in different indi viduals occur at the same age; in addition to that, the periods of biorhythms are approximately the same in all studied animals and remain unchanged during the whole individual development. It has been noted that the biorhythm with a period of 10.3 weeks is damped (its amplitude decreases from 8 µL O 2 /(h g) at the age of 20 weeks to 3 µL O 2 /(h g) at the time of death), and the biorhythm with the period of 7.2 weeks is sustained (its average amplitude is 2.4 ± 0.4 µL O 2 /(h g).
