Leks Summary

Leks by Jacob Hoglund

This text presents existing knowledge on two main aspects of lekking - the gathering together of males in small territories in order to display and thus attract a mate. It asks why leks evolve in some species and not others, and why females select their males through lekking, even though this process reaps little or no material benefits for them. In each case the authors emphasize the importance of understanding the selective forces that act on individuals in natural populations.

Leks Reviews

Leks are among the greatest wonders of the natural world. These aggregations of displaying male birds, mammals, and (by some definitions) insects, apparently existing solely as mating arenas where females come, mate with one or more highly popular males, and leave having obtained nothing more than sperm to fertilize their offspring, have captivated naturalists for centuries. Hoglund and Alatalo, experts in avian behavior and sexual selection, attempt to answer these questions and to place lekking systems in a broad context of sexual selection theory. Science
