POWRE: Links Between Anti-Predator Behavior and Mating Behavior

非技术摘要建议编号：9806038黑德里克，安这项研究调查交配行为和反捕食者行为可能联系的方式。雄蟋蟀(Gryllus Integer)从躲藏的地方鸣叫来吸引雌性蟋蟀。然而，叫声是危险的，因为叫声也会吸引捕食者。雌性蟋蟀更喜欢叫声较长的雄性，叫声持续时间是遗传的。比赛的长度将以雄性称为未受干扰的方式进行测量。捕食者回避行为将通过雄性在陌生环境中从庇护所出来所需的时间来衡量。如果交配行为和反捕食者行为在基因上是联系在一起的，时间较长的雄性将通过更加谨慎的方式来补偿它们明显的叫声，即从庇护所出来的速度更慢。为了测试对长途叫声有强烈偏好的雌性是否也很谨慎，将建造一个跟踪装置来测量雌性在向雄性叫唤时的运动。这个装置可以精确地测量每个雌性的喜好，并将这些喜好与她从避难所出来所需的时间进行比较。这项研究调查了两种基本力量在进化中的相互作用，即寻找配偶和生存。通过研究明确定义的、遗传的交配行为和捕食者回避之间的联系，这项研究将集中在这两种力量之间的进化平衡上。这将提供重要的见解，其结果将广泛适用于所有交配涉及显眼显示的物种。

NON-TECHNICAL ABSTRACT Proposal Number: 9806038 Hedrick, Ann This research investigates the ways in which mating behavior and antipredator behavior may be linked. Male crickets (Gryllus integer) call from hiding places to attract females. However, calling is dangerous because calls also attract predators. Female crickets prefer males with long calls, and call duration is inherited. Bout lengths will be measured as males call undisturbed. Predator-avoidance behavior will be measured as the time taken by a male to emerge from shelter in an unfamiliar environment. If mating behavior and antipredator behavior are geneticly linked, males with longer bouts will compensate for their conspicuous calls by being more cautious, i.e. emerging from shelter more slowly. To test whether females with strong preferences for long calls are also cautious, a tracking device will be built to measure the female's movement as she runs towards calling males. This device will allow precise measures of each females' preferences and the preferences will be compared with the time she takes to emerge from shelter. This study investigates the interplay of the two basic forces in evolution, finding a mate and surviving. By examining the links between well defined, inherited aspects of mating behavior and predator avoidance the research will focus on the evolutionary balance between these two forces. This will provide important insights and the results will be widely applicable to all species where mating involves conspicuous displays.
