Distribution and Abundance of Intertidal Sponge (Porifera) Communities in Coral Reefs of Singapore
Lim Shu Feng,Tan Lik Tong,Goh Beverly Pi Lee 한국해양과학기술원 2023 Ocean science journal Vol.58 No.4
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.

Studies concerning subtidal octocoral species from Singapore reefs are few. This study documents the diversity and abundance of octocoral communities from fringing reefs at Singapore’s Southern Islands, namely, Pulau Semakau, P. Hantu and Kusu Island. Belt transects of 20 m (× 5) were employed to survey the octocoral communities at these reef sites. Morphology and sclerites of a number of collected octocoral samples were compared with paratypes obtained from the Raffles Museum of Biodiversity Research, National University of Singapore, for species identification. A total of 16 morphotypes, belonging to five octocoral genera, including Cladiella, Lobophytum, Nephthea, Sarcophyton and Sinularia, were identified in this study. Statistical analysis revealed octocoral abundance and diversity at Kusu Island reefs were higher than those around P. Hantu and P. Semakau. Conversely, octocoral community structures encountered along P. Semakau and Kusu Island were more similar than those of P. Hantu. The preliminary data presented in this study could serve as the baseline data for long term biomonitoring programs in assessing the state of coral reefs in Singapore.
