Abstract

Time-course measurements of 15N tracer kinetics in particulate organic and in N+4 pools
from tropical and temperate regions were used to test several compartmental models describing the
exchange of I5N tracer in microplankton communities. Several lines of evidence suggested the involvement of a third, dissolved pool, arbitrarily labelled dissolved organic nitrogen (DON). Although the kinetic patterns of tracer movement were different between the tropical statlons and the temperate one, the same 3-compartmental model in which PON and DON can exchange material only through the intermediate of NH: gave the best fit. Only the transfer coefficients were modified. Results show that
compartmental analysis is useful for the estimation of compartmental transfer rates and for testing the assumptions implicit in any given model.
