Табл. 1. Характер лимитирования при потенциальном ограничении роста альгоценоза азотом (N) и фосфором (P).

Table 1. Domains of limitation when the algocoenosis growth is potentially limited by nitrogen (N) and phosphorus (P)

A - cellular quotas of algocoenosis components and boundaries and of strata in resources space generated by quotas.

B - belonging of nutrient media in the five experiments to different strata, in which community growth is restricted by different submultiplicities of available set of resources.
