Abstract

Gastropods are known to have a wide distribution. They can live in a variety of habitats and influenced by various environmental factors. The aim of this study was to investigate the diversity of gastropods and its relationship with the physical and chemical environment of a water. This research was an ecological research with correlational descriptive type. The selection of Marsegu Island was based on the fact that the area is a conservation area, both the forest and sea are frequently visited by tourists. The results of this research showed that there were 22 species of gastropod found in the water of Marsegu Island. The most commonly found was from the genus of Cypraea (5 species). Gastropods found mostly from the family of Strombidae which consisted of 4 genera i.e. Lambis, Canarium, Strombus and Lentigo. The value of gastropod diversity in the three research stations was moderate, 2.93, 2.91 and 2.95 respectively. In addition, there is a correlation between environmental factors and the diversity of gastropods. The simultaneous effect of the independent variables toward the dependent variables can be explained by the magnitude of the determination coefficient (R Square) which was 0528 or 52.8%. Result of this study confirms that the environmental factors greatly affects the diversity of Gastropod in the coastal waters of Marsegu island. The results can provide benefits as control over fishing and coastal pollution due to human activities.

Abstract

The heavy metal Hg is a global issue because it is toxic to living organisms. Therefore, monitoring levels of Hg in Ambon Bay is important to do. This is a study about monitoring the levels of heavy metals Hg in the waters of Ambon Bay in 2013 and 2014 by using Apogon beauforti as bio-indicators and Metalothionein-1 (MT-1) as a biomarker to determine the accumulation of Hg in relation to the concentration and expression of MT-1 in the tissue of A. beauforti. The samples used were 50 fish of A. beauforti taken at four different stations with purposive sampling procedure. The analysis of Hg content used AAS method, the expression of MT-1 was determined by western blotting method, and MT-1 concentrations were determined by using ELISA method in the laboratory of Brawijaya University. On the average, the results of the analysis of Hg content indicated that the accumulation of heavy metal Hg varied in four different stations. The levels of Hg in the tissue of A. beauforti in 2014 at station 1 increased, while the levels of Hg at stations 2, 3, and 4 decreased. However, the calculation results of MT-1 concentration by ELISA showed an increase in the concentration of MT-1 in 2014 compared to that in 2013. This result was supported with the fact that the protein tape expressed on the test results of western blotting was very thick. It indicated that the longer the organism exposed to heavy metals Hg, the more increased the accumulation of Hg. Thus, the expression and the concentration of MT-1 would also increase.

Abstract

The existence of macrozoobenthos in an ecosystem is closely related to the conditions of the surrounding environment. This research aimed to examine the physical chemical condition of aquatic environment and macrozoobenthos community structure in the coastal waters of Marsergu Island. This research was conducted in July and December 2016 in 3 stations. The data were collected by using sampling technique to measure the environmental factors (temperature, salinity, pH, and dissolved oxygen of seawater) and enumeration of gastropod species with in-situ. The results of this research showed that macrozoobenthos in the coastal waters of Marsegu Island consisted of 2 Phylum, namely Molusca and Echinoderms, that is, gastropod with 18 species, bivalvia with 5 species, and echinoderms with 17 species. Echinoderms was the dominant macrozoobentos with a percentage of 45%, followed by gastropods 42%, and bivalvia 13%. This suggests that echinoderms and gastropods are the main components that make up the macrozoobenthos community structure in the coastal waters of Marsegu Island. The results of the calculation of the diversity index of macrozoobenthos in the three research stations showed the highest score was station 1 as much as 3.56, station 2 as much as 3.52 and the lowest was station 3 as much as 2.07.

Abstract

Echinoderms are key species that govern the structure and balance of communities and influence the sustainability of other organisms in different types of ecosystems in sea water. This research aimed at examining the biodiversity of echinoderms, and environmental physical-chemical factors that affect the diversity of echinoderms in coastal waters of Marsegu Island. The data were collected with direct observation and all research variables were recorded. The data collection of echinodermata type was done on each plot in the middle intertidal zone and the lower intertidal zone. The results of this research found that the population of echinoderms in coastal water of Marsegu Island was composed of 4 classes, namely Ophiuroidea, Asteroidea, Echinoidea and Holothuriodea. The most common type found was Asteroidea which consisted of 3 families, 4 genera and 4 species. The results of observation showed there was a difference in echinoderm species found in the middle intertidal zone and the lower intertidal zone. The number of echinoderms species found in the middle intertidal zone was 8 species, while in the lower intertidal zone was 10 species, and there were some species that were not found in the middle intertidal zone, but they were found in the lower intertidal zone, namely Ophiopholis aculeafa, Linckia laevagata and Protoreaster nodusus. The Synapta maculata species was found in the lower intertidal zone, but it was not found in the midle intertidal zone. About 52% variation in echinoderms diversity can be explained by the regression equation model, while the remaining 48% was the influence of other factors that could not be explained by the regression equation model.
