Chain model of phytoplankton P , N and light colimitation

  title={Chain model of phytoplankton P , N and light colimitation},
  author={Markus Pahlow and Andreas Oschlies},
Models of multiple potentially limiting nutrients currently employ either multiplicative or threshold formulations, neither of which has a sound mechanistic explanation. Despite experimental evidence that lack of P severely constrains N assimilation, this mechanism has not been considered for constructing models of multi-nutrient limitation. We construct a phytoplankton optimal growth model linking C, chlorophyll (Chl), N, and P through a limitation chain in which P limits N assimilation, N… CONTINUE READING
