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

9603896韦伯的形态学的独特的连接之间的鱼鳔和mechanosensory侧线管道系统在热带珊瑚礁蝴蝶鱼的头部将首次描述。 据推测，这种独特的"侧向"连接使得通常仅对流体运动敏感的侧线系统对流体运动敏感，对压力刺激如声音敏感。 三维重建的组织学材料将被用来描述形态变化的lateroadenoma连接在三个蝴蝶鱼间谍，并比较它们与蝴蝶鱼在两个一般的缺乏连接，以更好地定义结构特征，这种感觉专业化。 在一个属中改变感觉系统功能的解剖学特化是罕见的。 侧沟连接是一个很好的系统，在其中研究的进化功能形态的感觉专业化。 蝴蝶鱼是一个著名的和生态上重要的属珊瑚礁鱼类，我们有一个不断扩大的机构的生态和行为数据，以及一个很好的支持假说的系统发育关系。 这项研究的结果将导致这种独特的感觉专业化的功能的合作神经解剖学和行为调查。

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.
