Sponges provide an array of ecological services and benefits for Caribbean coral reefs. They function as habitats for a bewildering variety of species, however limited attention has been paid in the systematics and distribution of sponge-associated fauna in the class Calcarea or for that matter of sponges in the Caribbean. The goal of this study was to characterize infaunal assemblages from a calcareous sponge, Clathrina lutea, across multiple reefs from the La Parguera Natural Reserve, Puerto Rico. The associated fauna from 43 C. lutea specimens yielded a total of 2,249 associated infauna distributed in seven invertebrate phyla. Arthropoda was the most abundant phylum accounting for 62.5% of total abundance, followed by Annelida (21.0%) and Nematoda (5.5%). Limited patterns of temporal or spatial variability were surmised due to the opportunistic sampling effort afforded to this investigation from the cryptic nature of this species. A concordance between our data set and those for the class Demospongiae were observed, with the most abundant associated fauna being copepods and polychaetes. However, when compared to other Calcarea, the present study found considerably more associated fauna.

在波多黎各拉帕尔格拉(La Parguera)的钙质海绵Clathrina lutea中栖息的相关生物

海绵为加勒比海珊瑚礁提供了一系列的生态服务和收益。它们充当令人困惑的物种栖息地,但是在Calcarea类或与加勒比海有关的海绵类动物相关的系统和分布方面,人们的关注很少。这项研究的目的是鉴定来自波多黎各La P​​arguera自然保护区的多个珊瑚礁上的钙质海绵Clathrina lutea的粪便组合。来自43个黄褐线虫标本的相关动物群共分布于7个无脊椎动物门中,共有2249个相关的动物。节肢动物是最丰富的门,占总丰度的62.5%,其次是Annelida(21.0%)和Nematoda(5.5%)。由于该物种的隐秘性质,本次调查提供了机会性抽样工作,因此推测了时间或空间变异的模式有限。观察到我们的数据集与Demospongiae类的数据集之间存在一致性,其中最丰富的相关动物群是co足类和多毛类。然而,当与其他加州乳猪相比时,本研究发现了更多的相关动物。
