Lekking as collective behaviour
Philosophical Transactions of the Royal Society B: Biological Sciences, 2023 Lekking is a spectacular mating system in which males maintain tightly organized clustering of territories during the mating season, and females visit these leks for mating. Various hypotheses—ranging from predation dilution to mate choice and mating benefit—offer potential explanations for the evolution of this peculiar mating system ...
