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.

9520553 Gerhardt Monocarpy，其中植物生长数年，然后经历一次致命的繁殖，当植物通过立即投入所有可用于繁殖的资源而获得不成比例的适应性大幅增长时，应该受到青睐。 先前对植物的研究主要集中在单果性如何通过提高交配成功率来使成年植物在其一生中受益。 拟议的研究将测试单果性是否也通过允许植物提供母性护理或护理效应而带来健康益处，从而在幼苗建立期间直接提高后代的存活率。 这项研究将增强对母性护理选择如何塑造植物生命史属性的基本了解。 这将是首批将亲代照顾考虑纳入植物繁殖策略解释的研究之一。
