SICB 2012 Society Symposium: Poecilogony, polymorphism or polyphenism: a window on larval evolutionary transitions in marine invertebrates; Charleston, SC; Jan. 3-7, 2012

Poecilogony是在海洋无脊椎动物中观察到的一种现象，其中一个物种能够产生两种不同的幼虫形式（必须进食才能生长的小型自由游泳幼虫，以及从母亲提供的蛋黄中获得营养的大型育雏幼虫）。这类物种提供了阐明导致早期发育差异的细胞和遗传机制以及不同幼虫类型对种群的影响的机会。这些资金将支持poecilogony在2012年1月在查尔斯顿，南卡罗来纳州的综合和比较生物学年会上的一个研讨会发言人将提出poecilogonous物种的最新研究，借鉴了人口遗传学，基因组学转录组学，发育生物学和生态学的前沿方法。其目的是促进这些研究人员之间的沟通，并鼓励跨学科整合方法的研究，以便更好地了解物种内发育的变化。研讨会将影响11位演讲者的研究生涯，其中包括9名女性（包括一名拉丁裔）和两名男性在不同的职业阶段（终身教职，终身教职，两名博士后和三名研究生），代表四个国家（加拿大，芬兰，巴拿马和美国）。它们所代表的机构也各不相同，有两所主要的本科院校（科尔盖特大学和哥伦比亚大学），几所研究型大学和一个政府机构（史密森学会）。研讨会的摘要发表在学会网站上，研讨会的手稿将提交给《综合与比较生物学》杂志发表。这些出版物将引起进化发育生物学家，无脊椎动物生物学家和其他有兴趣了解单一物种中相同基因组如何导致非常不同的幼虫的科学家的广泛兴趣。

Poecilogony is a phenomenon observed in marine invertebrates whereby a single species is capable of producing two different larval forms (small free-swimming larvae that have to feed to grow, as well as large brooded larvae that get their nutrition from yolk supplied by the mother). Such species provide the opportunity to elucidate the cellular and genetic mechanisms leading to differences in early development, as well as the consequences of different larval types for a population. These funds will support a symposium on poecilogony in January 2012 at the Society for Integrative and Comparative Biology annual meeting in Charleston, SC. Speakers will present the most recent research on poecilogonous species that draws on cutting-edge approaches in population genetics, genomics & transcriptomics, developmental biology, and ecology. The aim is to foster communication among these researchers and encourage studies that integrate methods across disciplines so variations in development within a species can be better understood. The symposium will impact the research careers of the diverse group of 11 speakers, which comprises nine women (including one Latina) and two men at various career stages (tenured faculty, tenure-stream faculty, two postdocs, and three graduate students), representing four countries (Canada, Finland, Panama, and USA). The institutions they represent are also varied, with two primarily undergraduate colleges (Colgate University; Acadia University), several research universities, and a government agency (Smithsonian Institution). The abstracts from the symposium are published on the society website and symposium manuscripts will be submitted for publication in the journal, Integrative and Comparative Biology. These publications will be of wide interest to evolutionary developmental biologists, invertebrate biologists, and other scientists interested in understanding how the same genome in a single species can lead to very different larvae.
