脊椎动物群落的行业协会结构的识别和分析在理解其社区组织和结构的基本机制中发挥了重要作用。这种方法一般还没有采取温带水域潮间带鱼类组合。在智利中部，鱼类是潮间群落的重要组成部分，但尚未进行试图了解其组织和结构的研究。在本研究中，饮食的13个最丰富的物种栖息在潮池中的岩石潮间带智利中部的确定。在5个地点共收集了660条鱼：Los Molles、Con-Cón、Quintay、El Tabo和拉斯克鲁塞斯。所有物种对之间的饮食重叠进行了计算，并构建了一个表型图的饮食相似性，并使用自举技术进行分析，以客观地确定公会成员。结果表明，智利中部潮间带鱼类群落可划分为3个摄食类群，其中2个类群由肉食性鱼类组成，1个类群由杂食性和草食性鱼类组成。由此产生的公会结构和潜在的影响，这些鱼类捕食潮间带群落的其他组成部分的可能原因和影响进行了讨论。
The identification and analysis of the guild structure of vertebrate assemblages has played a fundamental role in the understanding of the underlying mechanisms responsible for their community organization and structuring. This approach generally has not been undertaken for temperate water intertidal fish assemblages. In central Chile, fishes are important components of the intertidal community, but no studies attempting to understand their organization and structuring have been done. In the present study, the diets of 13 of the most abundant species which inhabit tidepools in the rocky intertidal zone of central Chile were determined. A total of 660 fishes was collected at 5 sites: Los Molles, Con-Cón, Quintay, El Tabo, and Las Cruces. Dietary overlap between all species pairs was calculated and a phenogram of dietary similarity was constructed and analyzed using a bootstrapping technique to objectively determine guild membership. The results showed that the intertidal fish assemblage of central Chile can be divided into three feeding guilds: two guilds consisting of carnivorous species and one guild of omnivorous and herbivorous species. The possible causes and implications of the resulting guild structure and the potential effects of predation by these fishes on other components of the intertidal community are discussed.
