Abstract

The existence of mole crabs had been reported from the southern coast of Central Java. However, no mole crab data was available from the northern coast Central Java.  This study aimed to figure out the existence of mole crabs in the northern coast of Central Java as revealed from the cytochrome c oxidase 1 (COI) barcoding. Mole crabs samples collected in Sendang Sikucing Beach Kendal. Taxonomic status of the samples was inferred from sequences similarity test using basic local alignment search tool to conspecific sequence deposited in GenBank. Pairwise genetic distances were calculated based on the Kimura 2-parameter model. A phylogenetic tree had reconstructed in molecular evolution genetic analysis (MEGA) software based on neighbor-joining algorithm. Branching reliability was obtained from 1000 bootstraps replication while branching polarity was obtained from the out-group comparison. The mole crab samples from the northern coast of Central Java had unambiguously identified as Emerita emeritus based on high sequences similarities (98.27%-99.70%), low genetic distances (0.002-0.005), and their monophyly with Emerita emeritus (KR047035) in GenBank. Pairwise analysis among each possibility pair of samples had genetic distances ranged between 0.000 and 0.005, indicated that all sample belong to single species. The data provide the first record of the existence of Emerita emeritus in the northern coast of Central Java. Our data on the existence of E. emeritus in the northern coast of Central Java is among essentials information as a scientific basis in creating policy for the management of sustainable use of the mole crabs in the areas.

Abstract

Acanthuridae is a marine fish family with some members are known as ornamental species. Previous studies has been reported the diversity of Acanthuridae. However, there was no study on the phylogenetic relationship of the Acanthuridae from Ujunggenteng and Taman Manalusu southern coast of West Java. The purpose of this study was to provide information about the phylogenetic relationship among ornamental fishes under the Acanthuridae family of Ujunggenteng Beach Sukabumi and Taman Manalusu Beach Garut, West Java. The phylogenetic tree was reconstructed based on morphological characters using maximum parsimony algorithm in software PAUP with 1000 pseudoreplicates and with Halichoeres marginatus selected as an outgroup species. The phylogenetic tree had a consistency index of 0.6429. The value means that the tree was highly reliable due to its low homoplasy. Acanthuridae formed a monophyletic clade compared to the outgroup species by having seven synapomorphic characters. Acanthurid clade was divided into two subclades at generic levels by nine derived characters; three apomorphic characters in Acanthurus and six apomorphic characters in Naso. The tree indicates that Naso brevirostris and Naso lituratus represents basal group, while all species within genus Acanthurus are the most advanced species.  This study is the first to provide the data about the evolutionary relationship of ornamental acanthurid fish from the southern coast of West Java. Data on closely related species is one of the essential scientific basis on making policies regarding the sustainable use of those closely related species.
