Why have birds got multiple sexual ornaments?
TLDR
Three hypotheses are examined that may account for the presence of multiple ornaments in males of many animals, including the multiple message hypothesis, the redundant signal hypothesis, and the unreliable signal hypothesis.
Do sexual ornaments demonstrate heightened condition-dependent expression as predicted by the handicap hypothesis?
TLDR
Despite the common claim that sexual ornaments are condition–dependent, the unexpected conclusion from the literature review is that there is little support from well–designed experiments.
THE EVOLUTION OF COSTLY MATE PREFERENCES II. THE “HANDICAP” PRINCIPLE
TLDR
A general additive quantitative genetic model is used to study the evolution of costly female mate choice by the “handicap” principle and applies to other sources of fitness variation like migration and host‐parasite coevolution, which cause effects equivalent to biased mutation.
Sexual Selection and Condition-Dependent Mate Preferences
TLDR
Accumulating support is shown for the hypothesis that high quality females show the strongest mate preference, and some of the wider implications of condition-dependent mating decisions and their effect on the strength of sexual selection are examined.
THE EVOLUTION OF COSTLY MATE PREFERENCES I. FISHER AND BIASED MUTATION
TLDR
This analysis shows that evolutionary stable exaggeration of female preference can be achieved if mutation pressure on the male character is biased, that is, mutation has a directional effect at this equilibrium female fitness is not maximized.
A resolution of the lek paradox
TLDR
It is shown that additive genetic variation is also higher in sexual traits, and often greater than in the same, non-sexually selected trait in females or other comparable traits in thesame species, contrary to the expectations of the lek paradox.
CONDITION DEPENDENCE OF SEXUAL ORNAMENT SIZE AND VARIATION IN THE STALK‐EYED FLY CYRTODIOPSIS DALMANNI (DIPTERA: DIOPSIDAE)
TLDR
Evaluation of male eyespan allows females to gain additional information about male condition over and above that given by body size, and accord well with condition‐dependent handicap models of sexual selection.
Condition-dependent signalling of genetic variation in stalk-eyed flies
TLDR
It is shown that genetic variation underlies the response to environmental stress of a sexual ornament (male eye span) in the stalk-eyed fly Cyrtodiopsis dalmanni, and this results strongly support the hypothesis that female mate choice yields genetic benefits for offspring.
CONDITION DEPENDENCE OF SEXUAL ORNAMENT SIZE AND VARIATION IN THE STALK-EYED FLY CYRTODIOPSIS DALMANNI (DIPTERA: DIOPSIDAE)
TLDR
Evaluation of male eyespan allows females to gain additional information about male condition over and above that given by body size, and accord well with condition-dependent handicap models of sexual selection.
THE EVOLUTION OF MATE PREFERENCES FOR MULTIPLE SEXUAL ORNAMENTS
TLDR
Sexual preferences for multiple Fisher traits are likely to evolve alongside preference for a single handicap trait that indicates male quality, showing a general difference in the evolutionary outcome of these two causes of sexual selection.
