Figure 1.
The mass- and temperature-dependent parameters of the model and a bifurcation diagram on a fertilization gradient. All parameter values are calculated for species with a body mass of 0.01 g at a temperature of 20°C. Shown are (a) the carrying capacity of the basal species (K (
)), (b) the growth rate of the basal species (r (
)), (c) the metabolism of a consumer relative to the basal species' growth rate (
, dimensionless), (d) the maximum consumption of the species relative to their metabolism (
, dimensionless), (e) the species' half saturation density relative to the carrying capacity (
, dimensionless) and (f) the biomass extremes of the three species (basal species: green; intermediate species: blue, top species: red, 
) on a fertilization gradient.
