9520553 Gerhardt Monocarpy, in which plants grow for several years then undergo one, fatal bout of reproduction, should be favored when a plant experiences a disproportionately large gain in fitness by investing all the resources it has available for reproduction at once. Previous research in plants has focused on how monocarpy might benefit the adult plant during its own lifetime through enhanced mating success. The proposed research will test whether monocarpy also confers fitness benefits by allowing plants to provide maternal care or nurse effects that directly increase offspring survival during seedling establishment. This research will enhance basic understanding of how selection on maternal care shapes the life-history attributes of plants. It will be among the first studies to incorporate consideration of parental care into explanations of plant reproductive strategies.

小行星9520553 一次结实，即植物生长数年，然后经历一次致命的繁殖，当一种植物通过一次性投入所有可用于繁殖的资源而在适应性上获得不成比例的巨大增益时，应该受到青睐。 以前对植物的研究集中在一次结实如何通过提高交配成功率使成年植物在其一生中受益。 拟议的研究将测试是否单性结实也赋予健身的好处，允许植物提供孕产妇护理或护士的影响，直接增加后代的生存在幼苗建立。 这项研究将加强对母性护理选择如何塑造植物生活史属性的基本理解。 这将是第一批将父母照顾的考虑纳入植物繁殖策略解释的研究之一。
