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

Sandy anemone (Heteractis malu), belongs to Phylum Cnidaria, physiologically is very close to coral stone, which was a major component of coral reef ecosystems. As coral stone, Heteractis malu also has symbiotic algae (Zooxanthella). Physiologically, the alga symbiotic relationship of coral stone is almost similar with Heteractis malu. Maintaining Heteractis malu in the laboratory is relativly easier compared to that of coral stone. Advantages of the Heteractis malu vs. stone coral, its body is not covered by limestone makingit easier in processing analyses. The response of the anemone to stress is expected similar with coral stone. This research aims to analyze the response and adaptation of Heteractis malu to the temperature increase of 1 °C and 2 °C of the normal temperature (28 °C). The impact of temperature increases on Heteractis malu did not significantly affect the density of zooxanthellae, however, there was a significant increase of mitotic index. In addition, during a recovery process, Heteractis malu immune system did not show a significant increase based on its mitotic index results tended to decrease during the second phase of stress treatment.Keywords: Adaptation, sandy anemone (Heteractis malu), temperature increase,, zooxanthellae

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

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

Acanthophyllia deshayesiana has a different habitat with Cynarina lacrymalis in the nature, but they have same character on living forms, diameter, and height of corallite. Both of these species are considered synonym, thus it needs verification study to describe whether it is synonym species or not based on morphological data. Eleven descriptive characters and seven morphometric characters were used to verify the synonym species of these coral. Descriptive data were performed by scoring method, while morphometric data were obtained from morphometric. Morphometric data were analyzed by Correspondence Analysis of Principal Coordinates (CAP) and Agglomerative Hierarchical Cluster (AHC), while descriptive data were analyzed by UPGMA (Unweight Pair Group Method with Arithmetic Mean). The result showed that both of these coral cannot differentiate based on morphometric measurement. It can differentiate significantly based on descriptive characters, so both of these coral are not synonym. Keywords: synonym, morphometric, descriptive, Cynarina lacrymalis, Acanthophyllia deshayesiana

Abstract

Cembranoid content in soft coral is known as a chemotype that relate with genotype and environment. This research aimed to characterize the cembranoid Sarcophyton soft coral from the reef that acidified by CO2 volcanic vents (pHT 7.8) at Volcano Islands waters, Banda-Neira (Indonesia), as a means of predicting the future impact of ocean acidification to the genetic diversity of Sarcophyton soft coral. 30 random colonies were taken, combined, and extracted with ethanol. Cembranoid isolation and identification had been done by high performance liquid chromatography and spectroscopic techniques. Results of the study found sarcophytol derivatives (sarcophytol A, 11,12-epoxy sarcophytol A, sarcophytol B, and sarcophytol M) as the only chemotype in the sample. This may suggest low genetic diversity in the observed Sarcophyton sample. Therefore, it may suggest that even soft coral is known to be resilient to future acidification pressures, the genetic diversity or the production of diverse cytotoxic metabolite may be hampered due to ocean acidification in future climate change adaptation.

Abstract

The anthropogenic provide a negative impact on the surrounding environment. Mangrove species, such as Sonneratia alba would get the impact of anthropogenic activities, to accumulate the pollution of heavy metals. The aim of this study were to evaluate mercury accumulation in Mangrove Apple (S. alba) and to analyze mangrove apple potency as mercury bioindicator. Samples were taken in April 2016 at Pari Island, Seribu Islands by purposive sampling. The results showed that the highest concentration of Hg in the Northern of Pari Island was found in the leaves and the lowest was in the fruit. The highest concentration of Hg in the Eastern of Pari Island was found in the leaves and lowest was in the fruit. The concentrations of Hg in the Eastern area higher the Northern area (significantly different). The accumulation of Hg mainly collected on the leaves with TF> 1, but the ability of S. alba trees absorb Hg in the environment showed a small value, namely BCF <1. The ability of S. alba in sediments, contaminated with mercury showed a high value of the leaves in the East Pari Island, but the fruit of S. alba both in the North and East of the Pari Island showed a small value.  Mangrove Apple leaves has a potency as mercury bioindicator organ.
