Abstract

Soft coral is predicted to outcompete with hard coral in future ocean acidification scenarios. Beside the biological resilience shown in acidic conditions, soft corals ability to maintain or compete for space is shown to relate with their ability to produce cytotoxic cembranoid-type compounds. The aim of this study was to investigate composition of cytotoxic cembranoid compounds of Sarcophyton glaccum soft coral exposed to current and predicted future ocean acidification scenarios. Sarcophyton glaccum colonies were acclimated along a pH gradient to simulate predicted increases in ocean acidification: natural/current (pH 8,2), slight increase in acidification (pH 8.0 year-1 2060), and moderate increase in acidification (pH 7,8 year­-1 2100). Cembranoid composition was determined by quantitative Nuclear Magnetic Resonance spectroscopy while cytotoxic activity was determined against tumor cell lines. Results of the study showed cytotoxicity and sarcophytoxide (the most active cembranoid compound in observed Sarcophyton glaccum) were both found to be higher at pH 8,0. However, a further increase of acidification resulted on a reduction of both the cytotoxicity and sarcophytoxide production. This suggests that acidification pressures affect directly the defense system metabolism of Sarcophyton glaccum and that while they may be resilient to small decreases in pH, their ability to compete for space may be hampered by more pronounced changes. Keywords: Cembranoids; Cytotoxic; Sarcophyton glaccum; Seawater Acidification; Soft Coral.

Abstract

Panggang Island is one of the snorkeling and diving area in the Seribu Islands. Number of tourists increase every year in line with the improving of tourism infrastructure such as tourist boat and dive shops. Tourism activities not only provide economic benefits but also give negative impact on coral reef ecosystem. The results of direct observations showed that there was destructive impact from snorkeling and diving. The most destructive behavior done by snorkeling and diver who has license was stepping on the coral reef. While the most destructive behavior by diver who has no license was holding the coral reef. The continued effect of tourist destructive behaviour grouped into three categories such as rubble, scratches on top of coral colony, and crushed coral colony. Based on the tourism impact analysis showed that diverwho has not been licensed gived the greatest damage impact,it was 13.55% per year of the ecological potential. While the impact of snorkeling touristwas 5.05% and diver who has license gived the smallest effect, it was 2.36%.  Comparison of coral reef data between 2010 and 2016 showed no significant changes to the coral reef, it means that until now coral reefs of Panggang Island still tolerate any disturbances including impact of tourism activities.Keywords : coral reef, diving, snorkeling, tourism, Panggang                      IslandPanggang Island is one of the snorkeling and diving area in the Seribu Islands.

Abstract

Black-band disease (BBD) is a persistent disease that cause the decline of the coral reef ecosystems, which is still slightly recorded in Indonesia, including in Pari Island, Thousand Islands. The objectives of this study were to determine progression, prevalence and incidence BBD on Montipora spp in shallow water of Pari Islands. Coral cover were estimated using line intercept transect (LIT) whereas the prevalence and incidence of BBD were carried out by using belt transect method with 1 m left and right of tape as long 20 m with 3 replications recorded approximately every two months. BBD progression was documented with a digital photograph method, the photograph of affected area of each coral was taken each day for 2 weeks. BBD was found to be spread in the surveyed area. The result show that prevalence and incidence of BBD showed a positive exponential relationship with water temperature. During the observation Both prevalence and incidence increased on May transitional season (wet-dry). The highest prevalence was found at 5,96 percent and whereas the maximum disease progression found at 0,46 cm/day.

Abstract

Latest stage development of recruit coral community in concerete artificial reefs were observed for nine months (from October 2009 to July 2010) by visual cencus and underwater photography methods. Amounts of 10 units of concrete artifical reef deployed in Pramuka Island waters and Gosong Pramuka in 2011 were used as an objects in this reseacrh. As a comparation, the conditios of coral coverand reef fishes in natural reef were observed by line intercept transcet, visual census, and underwater photography methods. In order to measure coral coberage area  we used a ImageJ 1.42q software. In march 2010, amounts of 457 coral colonies from 21 genera and 216 coral colonies from 16 genera were found on artifical reefs surface in Station 1 (Pramuka Island) and Station 2 (Gosong Pramuka) respectively. Number pf recruit coral colonies was dominated by genus Porites. Pocillopora, and Chypastrea. In july 2010, the precentage of coral cover on cencrete artifical refs reaches 41.46 ±13.37% (±SD) in Station 1 and 20. ±6.08% (mean ±SD) in Station 2, while the percentage of coral coverage on natural reefs were 23.14% and 40.43% in Station 1 and 2 respectively. Genus Porites become the most dominant genus in both of stations in terms recruit coloby abudance and percent cover. This result shows that concrete artificial reefs can effectively use to create new habitat of corals, coral fishes and other biota particularly in degraded coral reefs ecosystem.

Abstract

Coral diseases that have emerged since the early 1970s have caused significant regional ecological impacts. However, there has been a paucity of research into coral disease in South-East Asia, including Indonesia. This study provides baseline coral disease data in the Kepulauan Seribu Marine National Park. In this study we show a positive correlation between overall coral cover and the dominant reef building coral Montipora spp. and found two main diseases, black band disease (BBD) and WS, were highly prevalent throughout all reefs. Based on spatial location, the highest abundance of BBD (0.08 col./m2) was found at sites nearer (zone 1) to the mainland, whilst for WS (0.05 col./m2) highest abundance was found at middle sites (zone 2). According to the temporal data, the highest abundance of BBD (0.77 col./m2) was found during the transition period (between wet and dry seasons), whereas for WS higher abundance occurred within the dry season (0.07 col./m2). There was a significant difference in disease abundance among seasons which was correlated with increasing temperature and light intensity along with variations in total organic matters, nitrite and phosphate levels. Moreover, the middle sites experienced additional stress from the waste material originating from the mainland.

Abstract

Green turtle (Cheloniamydas; Testudines) is included in the group of polyandryanimals, which is single female mated with many male. DNA polymorphism method generally considered to have a high degree of accuracy as compared to other methods to elucidate polyandry phenomena on many animals. In this research, three microsatellite loci were used to identify the number and frequency of genotypes per locus, the number and frequency alleles per locus, and genotypes and number of alleles in the nest. The purpose of this research was to study the reproductive pattern of Cheloniamydas and compensation eggs of males from hatchling?s population in turtle conservation area of Pangumbahan Coastal Park, West Java. The result showed that from 10 nests, we could find 37 genotypes with 11 alleles for D108 locus, 21 genotypes with 9 alleles for B103 locus, and 27 genotypes with 9 alleles for C102 locus. The alleles number of each nest was more than 5 alleles for 5 nests, and more than 4 alleles for the remaining nests. Based on the probabilities of alleles contribution of each parent, the green turtle was polyandry animals.

Abstract

Lamun merupakan tumbuhan laut yang memiliki peran yang tidak kalah penting dengan ekosistem pesisir lainnya seperti terumbu karang dan mangrove baik dari segi fisik, ekologi, dan ekonomi. Indonesia memiliki 12 jenis lamun dari 58 jenis lamun di dunia. Tidak semua wilayah di Indonesia memiliki jumlah jenis yang sama karena perbedaan kondisi lingkungan atau tekanan antropogenik, sehingga perlu ada kajian keragaman jenis lamun di wilayah perairan Indonesia. Penelitian ini bertujuan untuk mengidentifikasi struktur komunitas lamun dan keterkaitan antara kerapatan lamun dan parameter lingkungan di perairan Pulau Wanci, Sulawesi Tenggara. Stasiun pengamatan berada pada daerah padang lamun yang dibagi menjadi 4 stasiun. Metode sampling yang digunakan mengacu pada McKenzie et al. (2001) menggunakan transek kuadrat 50 cm x 50 cm. Selanjutnya menghitung jumlah tegakan lamun dan mencatat jenis lamun yang ditemukan pada tiap transek kuadrat. Hasil penelitian menunjukkan bahwa ditemukan 7 jenis lamun di perairan Pulau Wanci yaitu Halophila ovalis, Halodule uninervis, Cymodocea rotundata, Thalassia hemprichii, Enhalus acroides, Thalasodendron ciliatum, dan Syringodium isoetifolium dengan kerapatan tertinggi didominasi oleh T. hemprichii, H. uninervis, dan C. rotundata dengan pola sebaran keseluruhan adalah mengelompok. Terdapat keterkaitan antara kerapatan lamun dengan parameter lingkungan, substrat berpasir memiliki korelasi positif yang tinggi terhadap kerapatan lamun sedangkan substrat liat, kecepatan arus, salinitas, dan suhu memiliki korelasi negatif yang rendah sampai tinggi terhadap kerapatan lamun di perairan Pulau Wanci.
