   INTRODUCTION
 
Sexual selection by direct and/or indirect benefits as well as sexual conflict determines the evolution of animal mating systems (e.g., Andersson and Simmons 2006Go). In polygynous mating systems, the female preference of apparently useless or deleterious male characteristics can be understood if a correlation between preferred male characteristics and direct benefits for the female exists (see polygyny threshold model, e.g., Orians 1969Go), such as improved paternal care or territorial quality (e.g., Price et al. 1993Go; Iwasa and Pomiankowski 1999Go). This issue is particularly interesting in facultative polygynous mating systems with biparental care because the female's choice of a polygynous male as a mate is most often accompanied by a reduction in paternal care by this mate (for a review, see Ligon 1999Go). Several studies (e.g., Johnson et al. 1994Go; Pribil and Searcy 2001Go; Moreno et al. 2002Go; but see Both 2002Go) . . . [Full Text of this Article]
