The proposed research will study how muscle function and bone movement (physiological features of organisms) correlate with structural (morphological) and behavioral features. Most work to date has focused on animal morphology, and relatively little research has been done on the physiological function of features of organisms as these functions relate to morphology and behavior. In particular, a general question of interest to comparative biologists will be addressed: how congruent are the distributions of physiological and morphological characteristics in organisms? The muscles and bones of the head region in fishes will be used as a model system to investigate this question. With nearly 23,000 species, ray-finned fishes comprise more than half of all vertebrates, and have proven to be an excellent model system for the study of animal function in the past. In addition, many of the fish groups to be studied are of considerable economic importance while others occur in regions of the world where there is great concern for the loss of biodiversity. This research will contribute to our understanding of (1) the utility of physiological data for testing comparative hypotheses in biology, (2) the biomechanics of bone and muscle function in vertebrates, and (3) our understanding of the biodiversity of the largest group of vertebrates.

这项拟议的研究将研究肌肉功能和骨骼运动(生物体的生理特征)如何与结构(形态)和行为特征相关。到目前为止，大多数工作都集中在动物形态上，而对生物特征的生理功能的研究相对较少，因为这些功能与形态和行为有关。特别是，比较生物学家感兴趣的一个一般性问题将被解决：生物体中生理和形态特征的分布有多一致？鱼类头部区域的肌肉和骨骼将被用作研究这个问题的模型系统。鳍鱼有近23,000个物种，占所有脊椎动物的一半以上，过去已被证明是研究动物功能的优秀模式系统。此外，许多待研究的鱼类群体具有相当大的经济重要性，而其他鱼类群体则生活在世界上对生物多样性丧失极为关切的地区。这项研究将有助于我们理解(1)生理数据在生物学中检验比较假说的有效性，(2)脊椎动物骨骼和肌肉功能的生物力学，以及(3)我们对脊椎动物最大类群的生物多样性的理解。
