Abstract

Gracilariaceae is a macroalgal family of Rhodophyta which can be found abundantly in tropical waters, including in Southern Coasts of Gunungkidul D.I.Yogyakarta, Indonesia. Coral and sand dominate the substrate of Southern Coasts of Gunungkidul, so it is an ideal habitat for Gracilariaceae. Along with the rapid development of coastal tourism areas, the existence of Gracilariaceae in this area needs to be studied intensively. Hence, this study aimed to determine species diversity and phenetic relationships of Gracilariaceae from Southern Coasts of Gunungkidul, including defining principal characters that influence clustering patterns. Field sampling was done by purposive method, followed by identification, characterization of morpho-anatomical, and phytochemical characters in Plant Systematic Laboratory Faculty of Biology UGM. Numerical Taxonomy for phenetic relationships analysis was computed using Clustering and Principal Component Analysis of Ordination methods by MVSP 3.1. The results of the Clustering analysis were presented as a phenogram while the PCA ordinance as a scattered plot. This study succeeded in finding five species of Gracilariaceae, i.e Gracilaria fergusonii, Gracilaria edulis, Gracilaria salicornia, Glacilaria canaliculata, and Glacilaria verrucosa. Phenetic relationships of Gracilariaceae were grouped into two main clusters and two sub-clusters. Clustering patterns were determined by the shape of holdfast, tip of thallus, surface texture of thallus, presence of cortex cells, fucoxanthin, neoxanthin, carotenoid, beta-carotenoid, cystocarp, pericarp, color, location, size, and characters of cystocarp, texture of thallus, and substrate characters.
