Abstract

A seagrass ecosystem has high productivity that supports many species of associated invertebrates, including sponges. However, seagrass beds with different habitat condition, including seagrass species composition and architectural morphotypes could affect the associative sponge in the ecosystem.   This study is aimed to find out about sponge species composition in different seagrass beds. The observation was conducted in two seagrass ecosystems at the east (site 1) and at the southeast (site 2) of Pramuka Island, Kepulauan Seribu, near Jakarta Bay, Indonesia. The Belt Transect was used to assess the density of sponges on the seagrass ecosystem, which was placed parallel to the coastline. The sponges species has higher number at the east than the southeast, with both sites was dominated by Spirastrella sp. and Agelas conifera. Correspondence Analysis (CA) results showed that sponges community has close interaction with seagrass abundance especially Cymodocea rotundata and Enhalus acoroides and architectural characteristic (patchily or continues meadows). Antibacterial assay of sponges tissue showed that only 7 sponge species has activity against targeting bacteria. The CA results also showed that sponge antibacterial activity was not correlated with seagrass species, with low bactericide and bacteriastatic activities. The implication of this result showed that sponges community can grow up at seagrass ecosystem eventhough their potential secondary metabolite activities is very low probably due to lack of stimulus mechanisms in the environment.

Abstract

This study is a part of transplanting Enhalus acoroides carried out from November 2006 to February 2007 as a compensation of 1.6 ha loss of seagrass beds at Bojonegara, which was facilitated by NGO Rekonvasi Bhumi and funded by oil drilling company, PT Apexindo. The transplanting site was located at Terate, Banten Bay which has muddy substrate with high water dynamic. Healthy transplant seedlings were collected from monospecific vegetation with muddy substrate of donor site at Kepuh. The seedlings of Enhalus have different length of rhizome, 5 and 10 cm, with leaf length of 60 cm and removed roots. Transplanting of Enhalus acoroides was conducted using single shoot seedlings with 9 seedlings per unit in 1 meter square with 5 replicates. Light coefficient (1.17-5.06) and percentage of silt and clay (86.45 ± 2.18 %) at transplant site Terate were both higher than the donor site Kepuh with light coefficient values of 1.21-2.46 and percentage of silt and clay 64.00 ± 5.57 %, respectively. Seedling growth survival of Enhalus acoroides in February 2007 with rhizome length of 10 cm was higher (51.11 ± 25.58%) than seedlings with rhizome length of 5 cm (17.78 ± 18.59%). Leaf length and wide Enhalus acoroides transplants decreased during the study. Water dynamic (waves) influenced light coefficient and turbidity at the transplant site. Field observations showed that mortality of Enhalus acoroides transplants was caused by mud smoothering the leaves and barnacle growing on them. They made the leaves lost their buoyancy, laid on the surface, rotten and finally died. Wave is one of the important physical factor affecting the transplanting seagrass on the muddy substrate.

Abstract

ABSTRAKCahaya matahari merupakan salah satu faktor lingkungan terpenting baik secara langsung maupun tidak langsung bagi organisme fotosintetik perairan dalam menyediakan energi untuk diubah menjadi energi kimia dengan bantuan klorofil. Penelitian ini bertujuan untuk mengkaji hubungan antara ketersediaan cahaya matahari  dan konsentrasi pigmen fotosintetik di Perairan Selat Bali. Penelitian dilaksanakan pada pagi, siang dan sore hari pada lima stasiun penelitian di Perairan Selat Bali. Analisis korelasi kanonik digunakan untuk mengetahui hubungan antara ketersediaan cahaya matahari dan pembentukan pigmen fotosintetik. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari (Y2) lebih berpengaruh terhadap pembentukan pigmen klorofil-b (Y1) dengan korelasi kanonik sebesar 0,4512 bilamana dibandingkan dengan pembentukan pigmen klorofil-a (Y1) dengan nilai korelasi sebesar 0,3982. Semakin tinggi pembentukan pigmen klorofil-b (Y1) dapat meningkatkan pembentukan pigmen karotenoid (Y1) secara signifikan dengan nilai korelasi kanonik sebesar 0,7419. Kesimpulan dari hasil ini, bahwa pigmen klorofil-b dan pigmen karotenoid akan terbentuk secara optimum pada intensitas cahaya rendah. ABSTRACTSunlight is one of the most important environmental factors both directly and indirectly for  photosynthetic organisms in providing energy to be converted into chemical energy with the help of chlorophyll. This study aims to examine the relationship between the availability of sunlight and the concentration of photosynthetic pigments in Bali Strait waters. The study was conducted in the morning, midday and afternoon at five research stations in the Bali Strait waters. Canonical correlation analysis was used to determine the relationship between sunlight availability and photosynthetic pigment formation. The results showed that the intensity of sunlight (Y2) had more influence on the formation of chlorophyll-b (Y1) pigments with canonical correlation of 0.4512 when compared with the formation of chlorophyll-a (Y1) pigment with a correlation value of 0.3982. The higher formation of chlorophyll-b (Y1) pigments can significantly increase the formation of carotenoid pigments (Y1) with canonical correlation values of 0.7419. From these results it can be concluded that chlorophyll-b pigments and carotenoid pigments will be formed optimally at low light intensities.
