ABSTRACT A central paradigm in evolutionary biology is that the fundamental divergence in
the fitness interests of the sexes ('sexual conflict') can lead to both the evolution of sex …

Sexual reproduction and the exchange of genetic information are essential biological
processes for species across all branches of the tree of life. Over the last four decades …

Across diverse taxa, seminal fluid proteins (Sfps) transferred at mating affect the
reproductive success of both sexes. Such reproductive proteins often evolve under positive …

Organisms require information to make decisions about fitness-affecting resources, such as
mates. Animals may extract" personal information" about potential mates by observing their …

Seminal fluid proteins transferred from males to females during copulation are required for
full fertility and can exert dramatic effects on female physiology and behavior. In Drosophila …

Food and sex often go hand in hand because of the nutritional cost of reproduction. For
Drosophila melanogaster females, this relationship is especially intimate because their …

The strongest form of intralocus sexual conflict occurs when two conditions are met:(i) there
is a positive intersexual genetic correlation for a trait and (ii) the selection gradients on the …

The most prevalent hypothesis concerning the relationship between reproduction and
longevity predicts that reproduction is costly, particularly in females. Specifically, egg …

Seminal fluid proteins (SFPs) directly influence a wide range of reproductive processes,
including fertilization, sperm storage, egg production, and immune response. Like many …

In Drosophila, the male sex pheromone cis-vaccenyl acetate (cVA) elicits aggregation and
courtship, through the odorant receptor Or67d. Long-lasting exposure to cVA suppresses …
