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

Oxidative damage is predicted to be a mediator of trade-offs between current reproduction
and future reproduction or survival, but most studies fail to support such predictions. We …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …

Male genitalia exhibit patterns of divergent evolution driven by sexual selection. In contrast,
for many taxonomic groups, female genitalia are relatively uniform and their patterns of …

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 …

Strong sexual selection has been reported to both enhance and hinder the adaptive
capacity and persistence of populations when exposed to novel environments …

Summary 1 We argue here that host plant quality affects many life‐history traits of
herbivorous insects and these traits often interact. Studies that look only at a limited number …

Sperm competition is widely recognized as a pervasive force of sexual selection. Theory
predicts that across species increased risk of sperm competition should favor an increased …

Life history theory predicts trade‐offs arising from the costs of reproduction: individuals
investing more into reproduction should have less energy available for their own somatic …

One of the most studied life-history trade-offs is that resulting from the cost of reproduction: a
trade-off arises when reproduction diverts limited resources from other life-history traits. We …
