Selection for sexually dimorphic traits and signal diversity in fiddler crabs
The evolution of diverse sexual signals and traits in animals is a promising yet challenging field in behavioural ecology. Sexual features are under the influence of a multitude, and often cryptic, mechanisms. In addition, the composition and strength of selection varies for each study species.
