AB  - Saprotrophic fungi are obliged to spend energy on growth, reproduction and substrate digestion.To understand the trade-offs involved, we developed a model which, for any given growth rate,identifies the strategy that maximises the fraction of energy that could possibly be spent on reproduction.Our model's predictions of growth rates and bioconversion effciencies are consistent withempirical findings, and it predicts the optimal investment in reproduction, resource acquisition andbiomass recycling for a given environment and time scale of reproduction. Thus if the timescaleof reproduction is large compared to the time required for the fungus to double in size, the modelsuggests that the total energy available for reproduction is maximal when a very small fraction of theenergy budget is spent on reproduction. The model also suggests that fungi growing on substrateswith a high concentration of low molecular weight compounds will not benefit from recycling: theyshould be able to grow more rapidly and allocate more energy to reproduction without recycling. Incontrast, recycling offers considerable benefits to fungi growing on recalcitrant substrates, where theindividual hyphae are not crowded, and the time taken to consume resource is significantly longerthan the fungus doubling time.
