Abstract

Abstract Given the important functional roles of sponges in the coral reef community, few studies have looked at sponge community assemblages in Singapore. This study was conducted to assess the sponge diversity, species richness, and species abundance of intertidal sponge communities in Singapore’s coral reefs, including Pulau Hantu, P. Subar Laut, Tanjong Rimau, and Labrador Park. Belt transects measuring 10 m by 1 m were established to survey the sponge communities at these reef sites. Based on sponge morphology, a total of 28 morphospecies were identified, belonging to eight different sponge orders, namely Chondrillida, Clionaida, Dictyoceratida, Haplosclerida, Poecilosclerida, Suberitida, Tetractinellida, and Verongiida. Univariate statistical analyses revealed that sponge diversity, species richness, and abundance at P. Hantu site 2 were significantly higher than that in Labrador Park. In addition, multivariate statistical analyses showed that in terms of community structure, there were three distinct clusters found at P. Hantu site 2, Labrador Park, and P. Subar Laut. The formation of these distinct clusters was sponge species specific and shaped by environmental factors and anthropogenic stresses. Preliminary sponge data presented in this study contribute to the regional biogeography of sponges and could serve as baseline data for future studies, including ecological research and biomonitoring of marine invertebrates, and support marine conservation efforts in Singapore.

新加坡珊瑚礁潮间带海绵(Porifera)群落的分布和丰度
鉴于海绵在珊瑚礁群落中的重要功能作用,很少有研究关注新加坡的海绵群落组合。本研究对新加坡汉图岛、P. Subar Laut、Tanjong Rimau和拉布拉多公园的潮间带海绵群落的多样性、物种丰富度和物种丰度进行了评估。建立了10 m × 1 m的带状样带,调查了这些珊瑚礁遗址的海绵群落。根据海绵形态鉴定出28个形态种,分属8个海绵目,分别为Chondrillida、Clionaida、Dictyoceratida、Haplosclerida、Poecilosclerida、Suberitida、Tetractinellida和Verongiida。单因素统计分析表明,P. Hantu 2站点的海绵多样性、物种丰富度和丰度均显著高于拉布拉多公园。此外,多元统计分析表明,在群落结构上,P. Hantu站点2、Labrador Park和P. Subar Laut有3个不同的群落。这些集群的形成是海绵物种特有的,受环境因素和人为压力的影响。本研究提供的初步海绵数据有助于海绵的区域生物地理学,可作为未来研究的基线数据,包括海洋无脊椎动物的生态研究和生物监测,并为新加坡的海洋保护工作提供支持。

期刊介绍: Ocean Science Journal is a scientific journal published quarterly (30th March, June, September, December) by the Korean Society of Oceanography (KSO) and Korea Institute of Ocean Science & Technology (KIOST). OSJ is international and interdisciplinary. Research articles, reviews and notes dealing with physical oceanography, biological oceanography/marine biology, chemical oceanography/marine chemistry, geological oceanography/marine geology, and marine pollution will be considered. Ocean Science covers the following fields: • physical oceanography: waves, currents, air-sea interaction, ocean modeling, coastal processes, water masses • biological oceanography/marine biology: plankton, benthic organisms, fish, ecology, molecular biology • chemical oceanography/marine chemistry: trace elements, isotopes, nutrients, organic substances, gases • geological oceanography/marine geology: geophysics, sedimentology, paleontology, paleogeopraphy, sediment dynamics • marine pollution: pollutants analysis and monitoring, fates of contaminants, aquatic toxicology, ecotoxicology • Promotes all aspects of ocean science, experimental, theoretical and laboratory researches OSJ aims to publish a very high quality scientific journal for researchers and other interested people throughout the world.
