Meeting: Hormone-mediated Male:Female Ratio Adjustment in Vertebrates, Society for Integrative and Comparative Biology, January 3rd-7th, 2013, San Francisco, CA

种群的性别比例是种群生存和种群内个体繁殖成功的主要决定因素。个体调整其后代的性别比例的能力，或者在成年水平上改变自己的性别，从而影响种群水平上的雄性和雌性的数量，是一个强大的概念，几十年来一直在进化的背景下进行讨论。虽然对于一些系统，如爬行动物和一些鱼类，通过环境线索改变性别的机制已经被详细研究过，但在其他系统，如鸟类和哺乳动物，令人惊讶的是，对性别比例调整的机制知之甚少。本次研讨会将汇聚研究鸟类、爬行动物、鱼类、人类和非人类哺乳动物性别调节荷尔蒙机制的研究人员，努力推动性别比调节研究的新研究途径。通过展示他们自己的脊椎动物系统中用于解决类似性别比例调整问题的新方法，我们将鼓励发言者之间的思想交流，并向SICB观众介绍潜在的研究途径，他们目前在各自系统中的研究可以证明是适用的。研讨会将包括9位发言者的演讲，其中包括1名助理教授、2名副教授、5名教授和1名高级讲师。九位发言者中有三位是女性，三位是外籍人士。努力包括在激素调节性别比调节领域拥有最高水平的专家，同时刺激(1)外国和美国研究人员之间的互动，(2)年轻科学家和知名科学家之间的互动，以及(3)在多个脊椎动物系统中激素调节性别比调节的联结处纳入代表性不足的群体。

The sex ratio of a population is a major determinant of the population's survival and the reproductive success of individuals within the population. The ability of an individual to adjust the sex ratios of the offspring they produce, or to change their sex at the adult level such that the number of males and females at the population level are influenced, is a powerful concept and one that has been discussed in an evolutionary context for decades. Although for some systems, such as reptiles and some fishes, the mechanisms by which sex can be altered through environmental cues have been addressed in detail, in other systems, such as birds and mammals, surprisingly little is known about the mechanisms of sex ratio adjustment. This symposium will bring together researchers studying hormonal mechanisms of sex adjustment in birds, reptiles, fishes, humans, and non-human mammals in an effort to stimulate new research avenues in the study of sex ratio adjustment. By demonstrating novel approaches in their own vertebrate systems used to address similar questions about sex ratio adjustment, we will encourage cross-fertilization of ideas among speakers and introduce the SICB audience to potential research avenues to which their current research in their respective systems could prove applicable. The symposium will include presentations by nine speakers, including one assistant professor, two associate professors, five professors, and one senior lecturer. Three of the nine speakers are women and three are foreign nationals. Efforts were made to include those with the highest level of expertise in the field of hormone-mediated sex ratio adjustment, while stimulating (1) interactions between foreign and US researchers, (2) interactions between young scientists and established scientists, and (3) incorporation of underrepresented groups at the nexus of hormone-mediated sex ratio adjustment in multiple vertebrate systems.
