Fig. 6. The start and end times for each culture chamber experiment (a), and the time course of culture system S C(DIC) together with a simple three-segment linear approximation of the time series (b), are used to estimate the growth-weighted 8 C(DIC) for each culture chamber. These estimates rely on assumptions about ontogenetic changes in calcite addition (mass per chamber, and days to add each chamber, each as a function of chamber number), as discussed in the text. The percentages in (a) show examples of these mass fraction estimates, for large and small B. aculeata in culture chamber CC-2002-12 (the bottom-most line in (a), with monthly tick marks). In this example, the growth-weighted S C(DIC) values used as reference values for large and small B. aculeata are +0.16 and +0.04%o, respectively.

In the study of population is estimated the populations status in a determinate moment and also its dynamics in time and space, it means the assessment of population dynamics and detection of inter and intrapopulation differences. This is usually not taken into account that each individual is ontogeny, and the popnilation estimate is a slice of the trajectories of individual development. In those cases where this is taken into account the possible ontogenetic change as something that interferes with population estimate, and the problem usually comes down to their elimination by the analysis of individuals of the same age. At the same time as a special analysis of individual ontogeny is not only necessary for the correct assessment of populations and their dynamics in time and space, but also for understanding the mechanisms of the stability of population processes.

In species possessing different chemical varieties, ontogenetic changes might be characteristic features not only of the species but also of the intraspeci c chemotype. 

Ontogenetic changes in chemical pro le of numerous taxa provide the basis for the ontogenetic hypothesis on the genesis of intraspeci c chemical taxa. Tetenyi (1970) assumed that differentiated intraspeci c taxa have emerged by adapting themselves to different life conditions.

These facts, and all the material we have previously examined on ontogenetic changes in the protein and enzyme spectrum, make it clear that the key to the understanding of the programming of biochemical development lies at the level of DNA-dependent genetic) RNA synthesis.
