在许多动物中，性别选择塑造了雄性的形态、生理和行为。乍一看，似乎有理由认为，在男女竞争中，女性在选择配偶时会使用与男性相同的男性特征和信号。然而，两性间和两性间的竞争可能会对性状产生相同或相反的影响，但强度不同。我们调查了通过雄性竞争选择了哪些颜色、形态和表现性状，以及雌性配偶偏好是否基于这些相同的性状和/或在三种雄性颜色形态中的优势地位。头部相对较大、咬合力相对较大的雄性更有可能赢得战斗，橙色雄性总是比其他变种占优势。然而，雌性更喜欢体型较大、身体状况较好的雄性的气味，令人惊讶的是，它们的咬合力能力较低。它们没有表现出对任何特定颜色形态的气味或更具统治力的雄性的气味的偏好。这些结果表明，两性间和两性间的竞争可能导致对不同的第二性性状的选择。(C)2012年爱思唯尔股份有限公司。版权所有。
Sexual selection molds the morphology, physiology and behavior of males in many animals. At first glance, it seems reasonable to assume that females would use the same male traits and signals in mate choice as males do during male-male competition. However, intra- and intersexual competition may affect traits in the same or the opposite direction, with differing strength. We investigated which color, morphometric and performance traits are selected for through male-male competition and whether female mate preference is based on these same traits and/or dominance status in the three male color morphs of the lizard Podarcis melisellensis. Males with relatively bigger heads and relatively higher bite forces were more likely to win fights and orange males were always dominant over the other morphs. Females, however, preferred scents of bigger males that were in better body condition, and surprisingly had lower bite force capacities. They did not show a preference for scents of any particular color morph or for scents of the more dominant males. These results indicate that intra- and intersexual competition may result in selection for different secondary sexual traits in P. melisellensis. (c) 2012 Elsevier GmbH. All rights reserved.
