RUI: Novel Specialization of the Lateral Line System: The Laterophysic Connection

9603896首次描述热带珊瑚礁蝶鱼头部的鱼囊和机械感觉侧线渠道系统之间的独特连接的形态。据推测，这种独特的“侧生理”连接使通常只对液体运动敏感的侧线系统对液体运动敏感，对声音等压力刺激也敏感。组织学材料的三维重建将被用来描述三个查托顿间谍的侧生理连接的形态变化，并将它们与两种缺乏联系的蝴蝶鱼进行比较，以更好地定义这种感官专门化的结构特征。在单个属中改变感觉系统功能的解剖学专门化是罕见的。侧生理连接是研究感觉特化的进化功能形态的一个很好的系统。Chaetdon是一种众所周知的重要的珊瑚礁鱼类，我们有越来越多的生态和行为数据，以及一个得到充分支持的系统发育关系假说。这项研究的结果将导致对这种独特的感觉特化的功能进行神经解剖学和行为学的合作研究。

9603896 Webb The morphology of a unique connection between the swim bladder and the mechanosensory lateral line canal system in the head of tropical coral reef butterflyfishes will be described for the first time. It is hypothesized that this unique "laterophysic" connection makes the lateral line system, which is normally only sensitive to fluid movement, sensitive to fluid movement, sensitive to pressure stimuli such as sound. 3-D reconstruction of histological material will be used to describe morphological variation in the laterophysic connection in three Chaetodon spies and to compare them with butterflyfishes in two general that lack the connection to better define the structural features that characterize this sensory specialization. Anatomical specializations in a single genus that change the function of a sensory system are rare. The laterophysic connection is an excellent system in which to study the evolutionary functional morphology of a sensory specialization. Chaetodon is a well-known and ecologically important genus of coral reef fishes for which we have an expanding body of ecological and behavioral data, and a well-supported hypothesis of phylogenetic relationships. The results of this study will lead to collaborative neuroanatomical and behavioral investigations of the function of this unique sensory specialization.
