The Behavioral Genetics and Evolution of Cricket Song

题目：蟋蟀鸣声的行为遗传学和进化，作者：Kerry L. Shaw co - pi。当前位置Patrick D. danley促成生殖行为的行为特征通常会迅速改变，并可能刺激新物种的产生。了解生殖行为的变化和物种的潜在分化，关键取决于了解哪些基因导致了行为变化，以及这些基因如何在发育中的生物体中产生这些行为。蟋蟀鸣叫的遗传基础，一种模式行为参与蟋蟀的生殖行为，将研究在夏威夷劳帕拉属。Laupala的物种是研究基因和行为之间联系的理想选择，因为(1)神经生物学家长期研究蟋蟀的鸣声，(2)蟋蟀鸣声的功能已经得到了深入的研究，(3)密切相关的物种拥有不同的雄性鸣声，这表明蟋蟀的鸣声在新物种的创造中发挥了作用，(4)蟋蟀鸣声的变化方式对测试进化假设有价值。在拟进行的研究中，将研究在密切相关的物种中自然发生的雄性鸣叫脉冲率变化的遗传基础。将开发遗传工具来识别影响雄性鸣叫的基因，并将这些基因的活性与不同物种雄性鸣叫的差异联系起来。即将被测试的假设是，蟋蟀歌唱行为发展的基因与自然行为变化的基因是相同的。

Title: The Behavioral Genetics and Evolution of Cricket SongP.I.: Kerry L. Shaw Co-P.I.: Patrick D. DanleyThe behavioral traits that contribute to reproductive behavior often change rapidly and may spur the creation of new species. Understanding how changes in reproductive behavior, and the potential differentiation of species, is critically dependent on knowing which genes contribute to behavioral variation and how these genes act to produce these behaviors in the developing organism. The genetic basis of cricket song, a model behavior involved in the reproductive behavior of crickets, will be studied in the Hawaiian genus Laupala. Species of Laupala are ideal for studying the connection between genes and behavior because (1) neurobiologists have long studied cricket song, (2) the function of cricket song has been intensively studied, (3) closely related species possess different male songs, which suggests that cricket song has played a role in the creation of new species, and (4) the way in which cricket songs have changed are valuable for testing evolutionary hypotheses. In the proposed research, the genetic basis of naturally occurring variation in pulse rate of the male calling song will be studied in closely related species. Genetic tools will be developed to identify genes influencing male song and to correlate the activity of these genes with differences in male calling song across multiple species. The hypothesis that will be tested is that genes underlying the development of singing behavior in crickets are the same genes that underlie natural behavioral variation.
