Fig. A1. Relationship between body size and density (carrying capacity) for 11 protist species used in the interaction experiment. Body size values (mean of the distribution) are taken from Giometto et al. (2013), which measured body size in identical environmental conditions of the experiment. Carrying capacities, K, are obtained from the 1-species experiment. The line, representing the Cross-Community Scaling Relationship (CCSR, from White et al. (2007)), is the best fit for , with best fit exponent b= -1.07, considering the variation associated to the experimental carrying capacities. Damuth' s rule (Damuth 1981) would have a value b= -0.75.
