The Role of Fluctuating Asymmetry in Mate Choice

摩尔9521821 我们的研究询问女性是否基于男性在发育过程中承受压力的能力而歧视男性。 这种能力反映在具有双侧表情的字符的波动不对称程度上。 我们将使用的实验操作，遗传实验和相关性研究的蟑螂，Nauphoeta cinera，解决几个问题：1）是女性的配偶选择或男性-男性竞争的影响程度的不对称性; 2）是能力，以减少不对称性遗传决定的;和3）环境和程度的近亲繁殖的影响波动的不对称性的重要性？ 这项研究将提供的信息，将有助于尽量减少交配的不利条件下饲养的生物控制和濒危物种计划的个人。 这些计划依赖于建立目标物种的繁殖种群。 要想成功，我们必须知道在自然栖息地中，来自受控繁殖计划的个体在竞争配偶时是如何表现的。 在这些程序中，许多用于饲养昆虫以供释放的做法，如近亲繁殖，导致波动不对称性增加。 我们的研究将提供信息，交配模式是如何影响女性歧视的程度不对称。

9521821 MOORE Our research asks whether females discriminate among males on the basis of the male's ability to withstand stresses during development. This ability is reflected in the degree of fluctuating asymmetry in characters that have bilateral expression. We will use a combination of experimental manipulations, genetic experiments, and correlation studies of the cockroach, Nauphoeta cinera, to address several issues: 1) is female choice of mates or male-male competition influenced by the degree of asymmetry; 2) is the ability to reduce asymmetry genetically determined; and 3) do environment and degree of inbreeding influence the importance of fluctuating asymmetry? This research will provide information that will help minimize the mating disadvantages of individuals reared in biological control and endangered species programs. These programs rely on establishing breeding populations of target species. To be successful we must know how individuals from controlled breeding programs fare in competition for mates in a natural habitat. Many of the practices use to rear insects for release in these programs, such as inbreeding, result in increased fluctuating asymmetry. Our research will provide information on how mating patterns are affected by female discrimination against the degree of asymmetry.
