POWRE: Links Between Anti-Predator Behavior and Mating Behavior

非技术摘要 建议编号：9806038 安？赫德里克 这项研究调查了交配行为和反捕食行为可能联系在一起的方式。 雄性蟋蟀（蟋蟀整数）呼吁从藏身之处，以吸引女性。 然而，叫声是危险的，因为叫声也会吸引掠食者。 雌性蟋蟀喜欢长叫声的雄性蟋蟀，叫声的持续时间是遗传的。比赛长度将被测量为男性呼吁不受干扰。避免捕食者的行为将被测量为男性从不熟悉的环境中的庇护所出现的时间。 如果交配行为和反捕食行为是遗传联系在一起的，那么交配时间较长的雄性会通过更加谨慎来补偿它们引人注目的叫声，也就是说，从庇护所出来的速度会更慢。 为了测试对长时间鸣叫有强烈偏好的雌性是否也很谨慎，将建造一个跟踪设备来测量雌性跑向鸣叫的雄性时的动作。 这个装置将允许精确测量每只雌性的偏好，并将偏好与她从避难所出来的时间进行比较。 这项研究调查了进化中两种基本力量的相互作用，寻找配偶和生存。 通过研究交配行为和捕食者回避的明确定义和遗传方面之间的联系，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和结果将广泛适用于所有物种的交配涉及显着显示。

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.
