ЕКСКРЕЦIЯ ФОСФОРУ ЗООПЛАНКТОНОМ У ЧОРНОМУ МОРI
The results of modeling accounts of excretion inorganic phosphorus by zooplankton in deep-water area of the Black sea are considered. Values of excretion rate inorganic phosphorus by zooplankton in a layer 0 – 150 м in winter varied from 2.45 up to 3.29, in spring - 4.25 – 8.81, in summer – 7.72 – 1...

Marine Ecological Journal| Summary: | The results of modeling accounts of excretion inorganic phosphorus by zooplankton in deep-water area of the Black sea are considered. Values of excretion rate inorganic phosphorus by zooplankton in a layer 0 – 150 м in winter varied from 2.45 up to 3.29, in spring - 4.25 – 8.81, in summer – 7.72 – 12.39, in autumn – 13.36 – 3.77 mgР·m-2·day-1. The quantitative estimation of the contribution of protozoan, mesoplankton and macroplankton in total excretion of phosphate specifies the key role protozoan. The contribution of protozoan on the average was 51 %, mesоplankton – 32 %, macroplankton – 17 %. Regeneration primary production in the winter changed from 17 up to 30 %, in spring 30 – 97 %, in summer – 93 – 100 %, in autumn – 100 – 44 %, and on the average for one year 64 %. The question on the role of "microbial loop" in regulation of the flow of phosphorus in euphotic zone of deep-water area of the Black sea is discussed. |
