Abstract

Research about crabs species (brachyura) in Lantangpeo, Tanakeke Islands, South Sulawesi has been conducted. The aim of this research was to know the crabs species on different type of mangrove microhabitat. Crabs collected with purposive sampling method in mangrove forest around the coastline, tidal creek, fish pond and sheltered waters between Lantangpeo island and Tanakeke island. From sampling activities there were found 28 species of crabs from 13 families. The number of crabs species in mangrove forest around the coastline were higher compared to another type of microhabitat. On the contrary, converted mangrove area (fish pond) were only supported least crabs species. It can be concluded that microhabitat in mangrove forest around the coastline supported more crabs species.

Abstract

Research about coastal forest vegetation in Sabutung island has been conducted.The aim of this research was to make an inventory of native species, introduced speciesand invasive spesies of plant in Sabutungisland. Sampling activities conducted withpurposive sampling method.Data collected with noted the plant species that foundduring exploring the island. All sample are photographed. Unidentified sample werecollected and identified in Marine and Environmental laboratory, Department ofBiology, Faculty of Mathematics and Natural Sciences, Hasanuddin University.Identification of the sample conducted based on: An Annotated Check-List of TheVascular Plants of The South China Sea and Its Shores by Turner et al. (2000) and Mangrove Guidebook for Southeast Asia by Wim Giesen et al. (2007)for coastal forestspecies; Tropical flowering plants: a guide to identification and cultivation by KirstenAlbrecht Llamas (2003) for introduced species andNonnative Invasive Plants of PacificCoast Forest. A Field Guide for Identification oleh Gray et al. (2011) and Guide to TheNaturalized and Invasive Plants of Southeast Asia by Arne Witt (2017) for invasivespecies. Data were analysed descriptively and displayed in tabular form. Antropogenicimpact i.e: land conversion and increased population were also discussed. From theresults of the study were recorded as many as 221 species of plants in Sabutung Island.Mostly dominated by ornamental plants and cultivated (introduced) plants with 131species of 46 tribes followed by native species with 67 species from 34 tribes. Invasivespecies were recorded with at least 19 species from 8 tribes. Nonetheless, invasivespecies are widespread and dominate space in almost all parts of the island. Most of thecoastal forest on Sabutung Island has been lost due to land conversion to settlementsand garden/plantation.

Abstract

The Research on Composition and Abundance of Biofouling Biota at Woodenpier at Karang-Karangan Beach Bua Sub-district of Luwu Regency was conducted from December 2016-June 2017. The purpose of this research is to know the types of macrobiofouling, and the abundance of macrobiofouling on the wooden pier on the Beach Coral-Karangan, Bua Sub-district, Luwu Regency. Sampling method using a quadrant plot and performed two data retrieves on the poles of wooden pier which were either exposed or unexpressed by water with 12 point stations. The results showed there were 8 species of 6 families: Saccostrea sp (ostreidae), Saccostrea cucullata (Ostreidae), Littoraria scabra (Littorinidae), Thais rufotincta (Muricidae), Septifer sp (Mytilidea), Cladophora glomerata (Cladophoraceae), Balanus sp (Balanidae), and Haemocinus sp (Planopilumnidae). Saccostrea sp has the highest average abundance ofmacrobiofouling on exposed wooden pier (223 ind/m 2). The lowest abundance of Thais rufotincta and Haemocinus sp (1 ind/m2), respectively.

Abstract

The structure of wing scales in four species of papilionid butterflies were The research about the condition of coral reefs in Baranglompo and Bone Batang island was conducted in January to April 2016 based on “Coralwatch” table. The aim of this study was to determine health condition of coral reefs in Baranglompo and Bone Batang island. The data was obtained in the south, west, and north at a depth of 3 meters and 10 meter using Line Intercept Transect (LIT) method along 100 meters of both islands. The health condition of coral reefs was obtained from four coral colony types specifically Branching, Massive, Tabulate, and Soft coral using Coralwatch method. The results of this study showed that the health condition of coral reefs in Baranglompo and Bone Batang islands was still relatively equal. At a depth of 3 meters, the most healthy coral colony was dominated by branching corals while at a depth of 10 meters dominated by massive corals. However, the average value of coral colors indicating coral condition showed that the health condition of coral reefs in Baranglompo was higher than that in Bone Batang island. High anthropogenic impacts were observed by the trash commonly found in Baranglompo island, many fish bombings also found in Bone Batang island. This study recommend that the health condition of coral reefs in Baranglompo island was greater than that in Bone Batang island.

Abstract

Tunikata memiliki peran yang sangat penting karena hewan ini banyak berkontribusi bagi kestabilan ekosistem laut dengan menyediakan lahan yang subur bagi biota lain, juga bagian dari rantai makanan serta mangsa bagi banyaknya biota laut. Penelitian bertujuan untuk mengetahui keanekaragaman tunikata yang masih sangat terbatas sehingga perlu dilakukan penelitian yang lebih mendalam. Sampling lapangan dilakukan menggunakan metode line transek pada kedalaman 5 m dengan panjang transek 20 m dan lebar transek 2 m. Semua tunikata yang terdapat dalam transek didata untuk selanjutnya diidentifikasi. Identifikasi jenis berdasarkan karakteristik morfologi disesuaikan dengan referensi identifikasi. Hasil identifikasi menunjukan, terdapat 24 spesies tunikata di kawasan perairan pulau Pannikiang, dimana semua jenis termasuk dalam kelas Ascidiacea. Parameter lingkungan di lokasi sesuai untuk menunjang kehidupan biota laut tersebut.
