Abstract

This research aims to prove the ability of phenotypic plasticity of Neritidae members in Lampon Banyuwangi, which is thought to be able to be used to determine the effects of mercury pollution that has been going on for more than a decade. The research method is descriptive quantitative with measurements of shell and operculum morphometry as phenotypic plasticity characters. Phenotypic plasticity analysis used non-Metric Multidimensional Scaling (nMDS) with Past 4.03 software. Based on the results of shell and operculum morphometry and nMDS similarity analysis, there were differences in the shell morphometry of Nerita argus and Nerita costata specimens from the Lampon estuary compared to specimens from the control location, namely Grajagan Beach. Nerita argus specimens from the rocky coast of Lampon had a range of morphometric ratios that were not much different from control specimens. Based on the results of these morphometric measurements, it show that the effects of mercury pollution have a greater influence on the phenotype of the Nerita argus and Nerita costata specimens located in the Lampon estuary compared to the rocky Lampon Beach specimens. The phenotypic plasticity of Nerita argus in the Lampon estuary can be a record of the behavior of mercury affecting marine biota, because the shell and operculum of this Gastropod member are influenced by environmental factors including pollutants, especially during the process of shell formation during its life.

Abstract

Exploration of the effects of mercury pollution in the Lampon estuary is still necessary, after there were indications of impacts on several bioindicator species. This study used spicule density of members of the order Holothuroidea as a bioassessment agent for the pollutant. Data collection on Holothuroidea populations was carried out using a quantitative descriptive method, using transects and 4 m2 quadrat plots. The species diversity index was analyzed using the Shannon-Weinner index. The main data collection locations were at the Lampon estuary and the rocky coast of Lampon, while control data was taken from the rocky coast of Rajegwesi, Merubetiri National Park. Spicule density was obtained by maceration of specimen tentacle organs, then spicules were observed and counted using a binocular microscope. The environmental parameters measured were water temperature, sediment temperature, water pH, water salinity, and dissolved oxygen (DO) in the water. The results showed that the diversity index of each study location was relatively low; the diversity index in Lampon was 0,838 and the diversity index in Rajegwesi was 0,826. A one-way ANOVA analysis showed no significant difference in spicule density in Holothuria leucospilota, but there was a significant difference in spicule density in Leucosynapta sp. at both locations. The suspected effects of mercury pollution on members of the Holothuroidea still require further investigation, although spicule density can be used as an agen of bioassessment.
