Figure 6From: Adaptive dynamic resource allocation in annual eusocial insects: environmental variation will not necessarily promote graded controlOptimal investment strategy (a), when 1% of the frequency distribution of season length is cut at the left side of the distribution (b). There is a prominent peak in sexual production just before minimum season length. Model parameters: worker productivity rate c = 0.15, survival rate q = 0.95, mean season length μ = 50, standard deviation σ = 8.7.Back to article page
