Abstract

This experiment was conducted to study the effects of anthropogenic stressor on the spatialvariability of secondary metabolites from marine sponge Aaptos suberitoides. Samplings wereconducted at 7 sites in Marine National Park of Thousand Islands that are extended within 30 kmoff Jakarta bay on late February 2011. Sponges were collected and quantified by means of liquidchromatography coupled with photo-diode array detection, whereas, cytotoxicity of sponges extractswas determined against T47D (breast) cancer cell lines. Results showed that the spatialproduction of aaptamine and isoaaptamine did not correlate with the quality of their surroundinghabitat, despite nitrite and nitrate levels significantly affected the bioactivity of crude extracts.

Abstract

Sponges are one of the most diverse benthos in the coral reef ecosystem. They have many morphological characters that are specific to species, and their existence is influenced by environmental conditions. The aims of this study are to observe the relationship between morphological and species diversity of sponges in coral reef ecosystem in the Lembeh Strait and investigate the most influential environmental factor on sponge diversity. The study was carried out between April and May 2013 at nine study sites. The methods used were belt transect and line intersect transect (LIT) installed parallel to the coastline at approximately 5-meter depth. Our study supports a positive correlation between the morphological diversity and species diversity of sponges. Many of the morphological growth types were specific to sites that have particular characteristics. The percentage of the live coral cover is not a critical factor for sponge diversity in the strait. Instead, dead coral with algae as a benthic category has a significant positive correlation with the morphological and species diversity of sponges. Conversely, rubble as a substrate type has a strong tendency to affect sponge diversity negatively. To conclude, it is important to maintain healthy reefs in order to sustain benthic communities that are valuable to ecological functions and societies. Keywords:sponges, diversity, coral reefs, Lembeh Strait

Abstract

Bangka Island is well known as the world’s largest tin producer. The inland and offshore tin mining has profound effects on the coastal environment, resulting in the high sedimentation in the water. Many corals suffered physiological damage due to low light intensity. The distribution of stony corals and the status of coral reefs was surveyed at 6 sites in West Bangka waters in October 2012. A total of 72 species of corals belonging to 33 genera and 12 families were found, and 4 species were distributed at all research sites. The live coral coverage was 36% on average and was categorized as being in fair condition. The coverage was 0% at Kamboja Island where the corals were the most affected by tin mining. The sediment flowed out from tin mining, blocked the light, and settled on the corals’ surface. Consequently, many corals were buried and the live corals decreased. It is obviously necessary to reduce and control the tin mining.

Abstract

Banggai waters, located in Central Sulawesi Province, is part of the worldâ??s coral triangle area which is wellâ??known to have the highest diversity on stony corals (Scleractinia). A research on stony corals has been carried out at 9 study sites between Juneâ??July 2011, practicing line transect methods and free collection in order to determine the recent condition and diversity of the given coral group. The average of live corals coverage was recorded at 46%(ranging between 24â??77%), and categorized as fair condition. The number of coral species found was 194, distributed in 54 genera. The Banggai waters condition was considered good and potential to sustain the coralsâ??growth. Even though so, in several particular areas, there were still threats on coral reefs.
