Which graph curve type would favor semelparity?
Under the graphical convention used in this life-history model, a concave-upward relationship favors concentrating reproductive effort into a single event, hence semelparity. Curvature determines whether fitness gains accelerate as more resources are committed. If a large one-time allocation yields disproportionately greater fecundity than several smaller allocations, preserving resources for another season is less advantageous. Selection can favor a large terminal effort when future survival is poor or when concentrating resources yields accelerating fecundity gains. Repeated breeding is favo
