Abstract

Lay SummaryIn response to competition, males should invest in premating traits (i.e., courtship) to enhance their mating success or in postmating traits (i.e., sperm) to increase fertilization success. We show instead that in the presence of a rival, spiders courting females with food gifts reduce both, investment in gifts and sperm. In competitive environments, accessing more females through low-quality gifts rather than allocating large amounts of sperm to each mating may confer highest fitness rewards.
