Trait selection and co-existence of phytoplankton in partially mixed systems: Trait based modelling and potential of an aggregated approach
Fig 3
Vertical distribution of aggregated properties of the trait distributions simulated with RM and AM at two Nini resulting in either unimodal or bimodal trait distributions (Nini = 35 mgP m-3, bimodal, Fig A-C; Nini = 50 mgP m-3, unimodal, Fig E-G).
The trait distributions at 0.75m and 9.75 m depth predicted by RM and AM are shown in (D) for Nini = 35 mgP m-3 and in (H) for Nini = 50 mgP m-3. The aggregated properties obtained from RM and AM are indicated by black and red lines respectively. Depicted are total concentration CT (A, E), average trait Trav and trait at maximum concentration Trcmax (B,F) and trait diversity FD80 (C,G). Note that Trcmax ofRM is indicated by a green line whereas in AM Trcmax = Trav and therefore identical to the red line. In all simulations turbulent diffusion was Kz = 5·10−5 m2 s-1 and simulation time was 1000 yr.
