Symposium: Environmentally Cued Hatching Across Taxa: Embryos Choose a Birthday

StrathmannIOS-1036933环境线索孵化跨类群：胚胎选择一个星期许多动物改变他们的孵化时间，以响应环境线索的风险和机会，影响鸡蛋和孵化的年轻。这些包括各种无脊椎动物（从寄生扁形虫到龙虾）和脊椎动物（鱼类，两栖动物，爬行动物和鸟类）。环境线索孵化的普遍，普遍的现象，主要是作为一系列孤立的情况下，限制了我们的理解，其多样性和共同的特点。环境提示孵化的综合和比较方法将提高我们对动物繁殖和早期生命阶段的理解。该项目是一个为期一天的专题讨论会，重点是胚胎作为受自然选择和对环境作出反应的生物体，以及孵化作为生态关键的过渡点。研讨会将于2011年1月6日在犹他湖城举行的综合与比较生物学学会会议上举行，会议记录将发表在《综合与比较生物学》杂志上。研讨会将汇集10位科学家，研究对各种环境条件、风险和资源作出反应的动物的孵化时间。贡献海报和演讲的相关会议将扩大参与者范围，并促进学生和知名科学家之间的互动。发言者将解决环境线索孵化的生态背景，发育和生理机制，使胚胎孵化或保持在鸡蛋在一系列的年龄和发育阶段，以及连接环境线索孵化过程的机制，包括胚胎和父母的相对作用。研讨会将建立一个统一的概念框架，研究环境线索孵化，并促进综合理解的多样性和共同性的胚胎对环境的反应。它将提高我们的进化，生态作用，孵化可塑性的机制，特别是胚胎行为更普遍的理解。

Karen L. Martin, Karen M. Warkentin and Richard R. StrathmannIOS-1036933Environmentally Cued Hatching Across Taxa: Embryos Choose a BirthdayMany animals alter their hatching timing in response to environmental cues to risks and opportunities that affect eggs and hatched young. These include diverse invertebrates (from parasitic flatworms to lobsters) and vertebrates (fishes, amphibians, reptiles, and birds). The widespread, common phenomenon of environmentally cued hatching has been studied largely as a series of isolated cases, limiting our understanding of both its diversity and its shared characteristics. An integrative and comparative approach to environmentally cued hatching will improve our understanding of animal reproduction and early life stages. The project is a one-day symposium focused on embryos as organisms that are subject to natural selection and responsive to their environment, and hatching as an ecologically critical transition point. The symposium will be held at the Society for Integrative and Comparative Biology meetings, in Salt Lake City, Utah, on January 6, 2011, and the proceedings published in the journal Integrative and Comparative Biology. The symposium will bring together ten scientists studying hatching timing in animals that respond to a wide variety of environmental conditions, risks, and resources. Associated sessions of contributed posters and talks will expand the range of participants and facilitate interactions between students and established scientists. Speakers will address the ecological context of environmentally cued hatching, the developmental and physiological mechanisms that allow embryos to hatch or to remain in the egg over a range of ages and developmental stages, and the mechanisms connecting environmental cues to the hatching process, including relative roles of embryos and parents. The symposium will build a unified conceptual framework for research on environmentally cued hatching and foster an integrated understanding of both the diversity and commonalities of embryo responses to their environment. It will improve our understanding of the evolution, ecological roles, and mechanisms of hatching plasticity in particular and embryo behavior more generally.
