Symposium on Maternal Effects as Adaptations, St. Louis, Missouri

1996年6月19日至23日，在密苏里州圣路易斯华盛顿大学举行的进化研究学会（SSE）会议上，将举行第一次关于母性影响作为适应性的专题讨论会。大约20名受邀与会者将在专题讨论会、专题论文会议和圆桌讨论期间介绍有关自然种群中产妇效应演变的最新和当前结果。来自国家科学基金会的资金将用于部分支持受邀演讲者的旅费和部分研究生津贴，以帮助编辑与牛津大学出版社将于1997年出版的论文集有关的杂务。选择参与者是为了对这一新兴领域提供广泛的报道；主题包括理论考虑，定量遗传估计，以及在各种植物和动物的生活史，行为和种群动态进化的母体效应的重要性。尽管过去母体效应在很大程度上被忽视，但进化生物学家越来越关注母体效应，因为他们意识到母体效应在自然界中非常普遍，并且可能经常代表一种“跨代表型可塑性”。在许多进化研究中，定量遗传设计的结合已经允许将表型变异分解为基因型、环境和亲本环境影响的组成部分。当寻求时，母体效应经常被观察到。例如，据报道，在植物、鸟类、蜥蜴、昆虫、两栖动物、鱼类和哺乳动物中，许多母性效应似乎具有适应功能。本次研讨会的目的是聚集一群杰出的生物学家，以统一概念和经验进展有关母体的影响在自然界。据信，这样的收集可以立即综合目前的知识状况，并确定未来调查的特定领域。

9622552 Mousseau The first symposium on Maternal Effects as Adaptations will be held during the 1996 Society for the Study of Evolution (SSE) meetings at Washington University, St. Louis, Missouri, June 19-23, 1996. Approximately 20 invited participants will present recent and current results concerning the evolution of maternal effects in natural populations during the symposium, contributed paper session, and roundtable discussion. Funds from NSF will be used to provide partial support for travel costs of invited speakers and for a partial graduate student stipend to help with editorial chores associated with a proceedings volume to be published by Oxford University Press in 1997. Participants were chosen to provide a broad coverage of this nascent field; topics include theoretical considerations, quantitative genetic estimation, and the importance of maternal effects to the evolution of life histories, behavior, and population dynamics in a wide variety of plants and animals. Although largely ignored in the past, maternal effects are receiving growing attention by evolutionary biologists as a direct consequence of the realization that maternal effects are very commonly observed in nature, and may often represent a form of "trans-generational phenotypic plasticity." The incorporation of quantitative genetic designs in many evolutionary studies has permitted the decomposition of phenotypic variation into components due to genotype, environment and parental environmental influences. When sought, maternal effects are frequently observed. For example, maternal effects, many of which appear to serve an adaptive function, have been reported in plants, birds, lizards, insects, amphibians, fish, and mammals. The objective of this symposium is to assemble a group of prominent biologists to unify conceptual and empirical advances concerning maternal effects in nature. It is believed that such a gathering can at once synthesize the current state of knowledge and identify particular areas for fu ture investigation.
