Fig. 6: Predicted total root length values of D. morrisiana from the logistic model when interacting with different sexes and kin.

a Total root length, b absolute growth rate (AGR), c relative growth rate (RGR) on a time basis, d relative growth rate (RGR) on a total root length basis. Gray shading indicates 95% confidence limits in the estimate for the accumulated growth and the two growth rates, as derived from population prediction intervals
