cuckoldry or parental care. Cuckolder males first mature at age 2. They follow a developmental sequence of sneaking and then mimicking female behavior to deceptively gain access to spawnings. Males who become parentals (construct nests, attract females, provide brood care) delay maturation until age 7. The parental investment of these males is parasitized by the cuckolders. This system is an example of a truly parasitically dependent mating strategy in vertebrates. A natural selection model is developed to predict the equilibrium frequencies of the two male types. A preliminary test of the model provides qualitative agreement.
骗婚或亲代养育。骗婚的雄性鱼在 2 岁时首次成熟。它们遵循一个发育顺序,即偷偷摸摸地模仿雌性行为,以欺骗性地获得繁殖机会。成为亲代的雄性(筑巢、吸引雌性、提供亲代照顾)会延迟到 7 岁才成熟。这些雄性的亲代投资会被骗婚者寄生。这个系统是脊椎动物中真正依赖寄生的交配策略的一个例子。建立了一个自然选择模型来预测两种雄鱼类型的平衡频率。该模型的初步测试提供了定性的一致性。
