Phytomass and photosynthetically active radiation distribution in the Zostera noltii Hornemann canopy in shallow water (the Black Sea)

摘要

A comparison of phytomass vertical distributions (W_(dry(z))/S_0) and photosynthetically active radiation (PAR) in Zostera noltii Hornemann canopy in a shallow waters conditions was made. It was found out that between PAR values and W_(dry(z))/S_0 there is a high inverse relationship of two types - power and exponential. In both cases, the correlation coefficient reaches the value of R~2=0.995. The averaged vertical PAR distribution in the canopy is well described by a fourth order polynomial function, with a correlation coefficient of R~2=0.998.
