项目摘要

Realizing the function of various animal constructions under fluctuating conditions or specific situations should need some feedback tuning mechanism between their structures and functions. Male mole crickets construct singing burrows for their acoustic communication. For several species, their singing burrows are known that the burrow structures amplify their calling songs. How this feedback tuning mechanism works on the mole cricket singing burrows would be understood by considering the relationship of cognition and behavior on the process of their singing burrow constructions. These approaches are essential for understanding the evolutionary process of the various animal constructions and the functions.Acoustic analysis of song variation of males and females of Gryllotalpa orientalis: Male songs were classified as two types: continuous calling song and short aggressive song. Whether the calling songs are different between long-winged and sort-winged individuals would be solved after detailed analyses with considering the recording conditions.The mechanism of tuning of singing burrow: Experiments that manipulated their acoustic recognition revealed that recognition of own songs related to their burrowing behavior. Recognition of own songs seemed to be essential to complete their singing burrow. The gradual process of constructing their singing burrows suggested that mole crickets use received acoustic information to improve their burrow structure or calling position.

实现各种动物结构在波动条件下或特定情况下的功能，需要其结构与功能之间存在某种反馈调节机制。雄性蝼蛄建造歌唱的洞穴，以进行声音交流。对于一些物种来说，它们的歌唱洞穴是已知的，洞穴结构放大了它们的鸣叫。这种反馈调节机制是如何作用于蝼蛄鸣洞的，我们可以通过考虑它们在鸣洞构建过程中的认知和行为关系来理解。这些方法对于理解各种动物结构和功能的进化过程至关重要。东方灰鲈雌雄鸣声变化的声学分析：将雄性鸣声分为连续鸣声和短攻击鸣声两种类型。长翅鸟与类翅鸟的鸣叫声是否不同，需要结合录音条件进行详细分析后才能解决。歌唱洞穴的调谐机制：操纵它们声音识别的实验表明，对自己歌曲的识别与它们的挖洞行为有关。识别自己的歌曲似乎对完成它们的歌唱洞穴至关重要。建造鸣叫洞穴的渐进过程表明，蝼蛄利用接收到的声学信息来改善它们的洞穴结构或叫声位置。
