Size-based model
Jennings et al. 2008, Proc. R. Soc. B; Blanchard et al. 2009 J Anim Ecol; Blanchard et al. 2010 Theor. Ecol.
Input: monthly plankton size spectrum and SST
Output: monthly population size spectrum
Assumes size-based predation, and size-specific growth and mortality are functions of food availability and SST
