The study of genital diversity has experienced rapidly burgeoning attention over the past few
decades. This research has shown that male genitalia in internally fertilizing animals exhibit …

Recent theory predicts that in species where females tend to mate with the relatively most
ornamented males, males may increase their attractiveness to females, and hence mating …

Aim Geographical gradients of vertebrate species richness are determined jointly by
evolutionary and environmental factors. Support for these factors comes mostly from …

Sexual selection can operate both before and after mating. For males, selection will favor a
suite of traits involved in mate acquisition (precopulatory) and in the competition among …

" This is a coursebook and reference guide for ichthyology courses that will also serve as a
tool for ichthyologists, fisheries scientists, marine biologists, and vertebrate zoologists. It will …

Sexual selection is a major force behind the rapid evolution of male genital morphology
among species. Most within-species studies have focused on sexual selection on male …

The remarkable diversity of sex determination mechanisms known in fish may be fuelled by
exceptionally high rates of sex chromosome turnovers or transitions. However, the …

Male intromittent organs are exceedingly diverse, yet we know comparatively little about
female genital diversity. However, the most direct mechanical interaction between males …

Male genital morphology is remarkably diverse across internally fertilizing animals, a
phenomenon largely attributed to sexual selection. Ecological differences across …

The study of male genital diversity has long overshadowed evolutionary inquiry of female
genitalia, despite its nontrivial diversity. Here, we identify four nonmutually exclusive …
