Abstract

The study aims to determine the distinguishing plant species within a plant community forest in the karst area of Maros-Pangkep. Plots of 20 meters by 20 meters were purposively established on 40 different locations representing proportionally facies of massif, porous, leyered and metamorphosed carbonate rocks. Tree dimensions in terms of height and diameter of trees in every plot were measured. The data were examinated through table method and principal component analysis (PCA). The study indicated that the distiguishing plant species determined by table method, only could diffrenciate between the group of communities over massif, porous rock facies and the group of communities over layered, metamorphosed rock facies. Whereas, determining plant species characteristic by PCA method gave sharper interpretation about the distiguishing plant species of plant communities among massif, porous, layered and matamorphosed rock facies.

Abstract

The Lantebung mangrove ecosystem in Makassar City is one of the mangrove ecosystems in Makassar City, which has been used by the community as a mangrove tourism area. The purpose of this study was to determine the level of species diversity and the dominate of gastropod species in the Lantebung Mangrove ecosystem, Makassar City. This research is an exploratory descriptive research. Determination of stations is done by purposive sampling with 3 research stations. Where is every station. At each station a 20 meter long transact was made with 5 subplots measuring 1m x 1m. The results of this study indicated that the index of gastropod diversity in the Lantebung mangrove ecosystem, Makassar City is in the medium class with a value of 1.235. The Dominance Index found that the Dominance of Gastropod Species was in the low class with a value of 0.388.
