Chemical signals are omnipresent in sexual communication in the vast majority of living
organisms. The traditional paradigm was that their main purpose in sexual behaviour was to …

Papers on sexual selection often highlight the incredible diversity of sexually selected traits
across animals. Yet, few studies have tried to explain why this diversity evolved. Animals use …

Many insect species use multi-component sex pheromones to discriminate among potential
mating partners [1–5]. In moths, pheromone blends tend to be dominated by one or two …

Males of many species choose their mate according to the female's reproductive status, and
there is now increasing evidence that male fitness can depend on this discrimination …

Abstract Yellow mealworms (Tenebrio molitor; Coleoptera: Tenebrionidae) are currently the
most farmed holometabolous insect species in the insects as food and feed industry, with …

The evolution of male preferences and of female ornaments in species with traditional sex
roles (ie, polygyny) have been highlighted as areas in need of more active research by an …

Sexual selection is a major force driving the evolution of diverse reproductive traits. This
evolutionary process is based on individual reproductive advantages that arise either …

When females mate with multiple partners, the risk of sperm competition depends on female
mating history. To maximize fitness, males should adjust their copulatory investments …

Numerosity discrimination, the ability to distinguish between sets with more and less items,
is recognised as the foundation for higher numerical abilities. Understanding numerosity …

Sexual selection theory asserts that females are well adapted to sense signals indicating the
quality of potential mates. One crucial male quality parameter is functional fertility (ie the …
