Aggressive and cannibalistic female spiders can impose strong selection on male mating
and fertilization strategies. Furthermore, the distinctive reproductive morphology of spiders is …

Simple Summary During insect mating, male insects trigger post-mating responses in
females through seminal fluid proteins, inducing a physiological transition in females that is …

Sperm competition drives traits that enhance fertilization success. The amount of sperm
transferred relative to competitors is key for attaining paternity. Female reproductive …

Male mate choice is predicted in systems with high costs of mating, as for those with male
nuptial gifts and/or sexual cannibalism. We ask whether males of the nuptial gift-giving …

The male genitalia of pholcid spiders, which is one of the most species-rich spider families,
are characterized by a procursus, which is a morphologically diverse projection of the …

Success in sperm competition is an important determinant of male fitness in mating systems
with female multiple mating. Thus, sperm competition risk represents a key dimension of the …

Chemical signals play a crucial role in reproduction as a means for locating mates and/or
gaining information about their quality, ultimately affecting mating system dynamics and …

According to the sperm competition risk (SCR) model, males should increase their
investment in ejaculates when there is a high chance that their sperm will compete for …

In many species, males exhibit phenotypic plasticity in sexually selected traits when
exposed to social cues about the intensity of sexual competition. To date, however, few …

Biases in adult sex ratios can alter the intensity of sexual selection by enhancing competition
for mates. Under intense competition males increase their investment in behaviors to …
