... and Huntly, 2000 ; Vanni, 2002 ). Most importantly, a significant portion of the nutrients that support primary production in lakes is derived from excretion by zooplankton (Sterner et al., 1992 ). Considerable attention has focused on nitrogen (N) and phosphorus (P) since they are the nutrients that most...

In this study, we present a modelling exercise that aims to draw inference on the relative contribution of various external and internal flux rates to the phosphorus budget of Cootes Paradise. We first examined the capacity of a phosphorus mass-balance model...
