Abstract

This study aimed to identify the types of soft corals of the family Alcyoniidae based on their morphological characteristics and spicule shape; determine the composition of the type and vertical distribution of soft corals; and  analyze the relationship between the distribution of soft corals of the Alcyoniidae family in the fore reef  zone with environmental factors in the waters of Barranglompo Island. This research was conducted in the coral reef area on the edge of Barranglompo Island which is divided into four observation stations. Data on species and the number of soft coral colonies were collected using the 100-meter belt transect method, which was placed parallel to the shoreline at two depths. This study identified 23 soft coral species belonging to three genera: Sinularia, Lobophytum, and Sarcophyton. Five spicule models were found: clubs, capstan, shuttel, spindle, and barrel, and the dominant one was the shape of clubs. There was no significant difference in the number of types between the research stations in the upper and lower reef zones. The density of soft corals differed markedly between stations in the lower fore reef zone, with the highest density of 0.19 ind/m2 at the southern station of the island. The high density of soft corals was located in the southwest of the island in the upper and lower fore-reef  zones andwass associated with high light intensity and salinity. The high richness of soft coral types is located in the southeast of the island in the upper and lower fore-reef zones, which are characterized by turbidity values and high temperatures.

Abstract

Morphologycal characterstic both descriptive and morphometric, like corralite diameter, corralite shape, the presence or absence of paliform lobe, colonies surface form, and septa teeth were the key for determining the Favites coral species characters, but these character are often influenced by environmental factors. In this studi will be try to reconstructed phylogeny tree of Favites coral‟s (Favites abdita, F. benattae, F. chinensis, F. flexuosa, F. halicora, and F. paraflexuosa). The speciment collected from Spermonde Archipelago. Phylogeny tree was reconstructed based on the morphological characters (descriptive and morphometric) using UPGMA (Unweighted Pair Group Method with Arithmetic Mean) Methood on PAUP 4.0 software. The result showed the grouping of taxa for each species. However, if only using morphometric character in preparing the taxa group, it will not show the clear differences among species. This caused by the morphometric characters have the highest plasticity and influenced by environmental factors, if compared with the descriptive character.
