Title: Condition-Dependent Reproductive Strategies in a Fish with Male Parental Care PI: R. Craig Sargent Non-Technical Summary Animals acquire resources throughout their lives, which they ultimately invest in fitness: i.e. survival and reproduction. The study species for this research, the fathead minnow, is a fish in which males perform all parental care. Past work with this species has shown that males with higher energy reserves are more likely to win contests for nest sites with other males, are more likely to be chosen as mates by females, and are more likely to sire a lot of offspring over an entire breeding season. This research will specifically investigate now males allocate resources to their breeding coloration. It will also study how this coloration may function as a signal to attract females, as a signal of dominance to rival males, or both. Manipulation of male energy reserves, through manipulation of diet, will be used to determine how energy reserves may influence male breeding coloration and fitness. The results of this research will provide insights into how energy reserves (and overall health) affect animal signals, communication, reproductive success, and fitness.

职务名称： 一条有雄性父母照顾的鱼的条件依赖性繁殖策略 主要研究者： R.克雷格萨金特 非技术性总结 动物在其一生中获得资源，最终投资于健康：即生存和繁殖。 这项研究的研究物种，黑头呆鱼，是一种由雄性承担所有父母照顾的鱼。 过去对这个物种的研究表明，具有较高能量储备的雄性更有可能赢得与其他雄性的筑巢地点的竞争，更有可能被雌性选为配偶，并且更有可能在整个繁殖季节中繁殖大量后代。 这项研究将专门调查现在的男性分配资源，他们的繁殖颜色。 它还将研究这种颜色如何作为吸引雌性的信号，作为竞争对手雄性的优势信号，或两者兼而有之。 通过控制饮食来控制雄性动物的能量储备，将用于确定能量储备如何影响雄性动物的繁殖颜色和健康。 这项研究的结果将提供关于能量储备（和整体健康）如何影响动物信号、交流、繁殖成功和健康的见解。
