SEXUAL SELECTION AND THE EVOLUTION OF MATING SYSTEMS

Inclusive fitness theory and eusociality
TLDR
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.

Bower destruction and sexual competition in the satin bowerbird (Ptilonorhynchus violaceus)

  • 1 December 1985
TLDR
Results show that male interactions are important in determining differences in the quality of display among male satin bower-birds, and are consistent with the view that females use bowers as indicators of male quality in mate choice.

Variable female preferences drive complex male displays
TLDR
In satin bowerbirds (Ptilonorhynchus violaceus) female mate choice is a multistage process, where females of different ages use different male display traits in successive stages, suggesting age- and stage-specific female preferences may contribute to explaining the widespread occurrence of multifaceted male displays.

Sexual selection: Male displays adjusted to female's response
TLDR
It is demonstrated that male satin bowerbirds do not always display at maximum intensity — rather, successful males modulate their displays in response to signals from females, indicating that sexual selection may favour those males that can produce intense displays but which know how to modify these according to the female response.

Threat Reduction as a Cause of Differences in Bower Architecture, Bower Decoration and Male Display in Two Closely-Related Bowerbirds Chlamydera nuchalis and C. maculata
TLDR
It is proposed that increased separation between bowers has caused selection for vigorous male display as part of mate assessment, and an effect of this change is that female visitors to bowers are threatened by the increased vigour in male display.

Complex male display and female choice in the spotted bowerbird: specialized functions for different bower decorations
  • G. Borgia
  • Environmental Science
    Animal Behaviour
  • 1 May 1995
TLDR
Results from the continuous monitoring of bowers show that a few males account for the majority of matings, the two most common decoration types, bones and glass, explain a large proportion of the variation in male mating success and large inter-bower distances relate to low levels of decoration stealing and bower destruction.
