中文摘要
研究生活史策略进化的生物学家研究性状之间的权衡,以了解自然选择如何作用于最大限度地繁殖成功。一个基本的权衡发生在后代的大小和数量之间:一个有机体可以产生许多小的后代,或者只产生几个大的后代。有一大堆理论解释了这些策略如何影响繁殖成功,但在动物身上,只有两组人对这一理论进行了测试:脊椎动物和海胆。这项拟议的研究使用实验胚胎学技术在更多样化的动物中测试理论,包括双边对称动物的三个主要谱系中的两个:后口动物(半角动物和棘皮动物)和轮虫动物(环节动物、扁虫和软体动物)。拟议的工作将两个机构的研究和教育结合在一起,重点是提供有意义的学生研究经验。这笔赠款将支持开发一系列基于网络的教学计划,供任何高等教育机构采用。这些课程计划将通过在两所大学的入门和高级生物课程中运行的一系列试点计划来制定。助学金将为8-10名本科生和一名研究生提供直接支持,而课程计划将为数百名额外的学生提供课堂研究机会。
英文摘要
Biologists studying the evolution of life history strategies examine trade-offs between traits to understand how natural selection acts to maximize reproductive success. One fundamental trade-off occurs between the size and number of offspring: an organism can produce many small offspring, or just a few large offspring. There is a large body of theory explaining how these strategies affect reproductive success, but in animals, tests of this theory have been done in only two groups: vertebrates and sea urchins. The proposed research uses experimental embryological techniques to test theory in a much more diverse suite of animals, including members of two of the three major lineages of bilaterally symmetric animals: deuterostomes (hemichordates and echinoderms) and lophotrochozoans (annelids, flatworms, and molluscs). The proposed work integrates research and education at two institutions focused on providing meaningful student research experiences. The grant will support the development of a series of web-based lesson plans that will be made available for adoption by any institution of higher learning. These lesson plans will be developed through a series of pilot programs run during introductory and upper level biology classes at both institutions. The grant will provide direct support for 8-10 undergraduates and one graduate student, while lesson plans will provide in-class research opportunities for hundreds of additional students.
