There has recently been an increase in interest in the notion that female ornamentation is selected through male choice, rather than being an artefact of selection on male ornamentation. There are, however, key differences between the sexes in the type of selection pressures that are likely to generate ornamentation and important differences in investment tradeoffs. Here, I discuss that female ornamentation might be selected more often through female competition over resources than through competition over mates, as exemplified in a recent study by Heinsohn and colleagues.
最近,人们对这样一种观点的兴趣有所增加,即雌性的装饰物是通过雄性选择而产生的,而非雄性装饰物选择的一种附带产物。然而,在可能产生装饰物的选择压力类型上,两性之间存在关键差异,并且在投资权衡方面也存在重要差异。在此,我讨论了雌性装饰物可能更多是通过雌性对资源的竞争而非对配偶的竞争而被选择的,海因索恩及其同事最近的一项研究就是例证。
