Komparasi Deversitas Moluska Musim Hujan dan Kemarau Di Kawasan Mangrove Luppung, Kabupaten Bulukumba

This study aims to determine the diversity of molluscs (bivalves and gastropods) in two seasons mangrove ecosystem Luppung, Ujung Loe District, Bulukumba Regency. Data collection usied random plot size I x m2, which applied at six stations determined by Purposive Sampling Method. Species Identification based on morphological characteristics some other identification references. analysis including diversity, uniformity dominance. The degree similarity amongst station was analysed using Clustering Bray-Curtis method. used PAST 4.03. In this studi, 37 species molluscs, consisting bivalve class (19 species) gastropod (17 were identified. Bivalve Tellina (Quidnipagus) palate (Iredale, 1929) GastropodsNassarius (Plicarcularia) leptospirus (A. Adams, 1852) found all research stations. SpeciesCorbicula japonica (Prime, 1864). Uncertain Nerita (from bush, 1844), Oualaniense Clithon (Lesson, 1831), Episcomitra cornicula (Linnaeus, 1758), Rough coastlines Pugilina cochlidium Melanoides punctata (Lamarck, 1822), Polinices mammilla 1758),and Rhinoclavis aspera 1758) only one station. frequency appearance type mollusk shows distribution location. highest Bivalvia is 1 during dry season 2 rainy season. Gastropod values 3 Diversity Gastropods higher There no structure community between seasons. little Penelitian ini bertujuan untuk mengetahui keanekaragaman moluska (bivalvia dan gastropoda) pada dua musim di ekosistem Dusun Luppung Kecamatan Kabupaten Bulukumba. Pengambilan data menggunakan metode acak stasiun ditentukan dengan Enam berukuran m2 diaplikasi enam stasiun. Identifikasi berdasarkan karakteristik morfologi disesuaikan referensi identifikasi. Analisis meliputi keanekaragaman, keseragaman, dominansi. Tingkat kesamaan (similaritas) antar analisis Bray-curtis, Aplikasi Pada studi ini, Teridentifikasi (jenis) moluska, terdiri dari klas bivalvia Gastropoda species). jenis palatam Nassarius dijumpai semua penelitian. Corbicula incerta (von dem Busch, oualaniense Littoraria scabra hanya temukan salah satu Frekuensi pemunculan menunjukan sebaran tersebut lokasi Nilai tertinggi terdapat Kemarau Hujan. Keanekaragaman Moluska (Bivalvia dana Gastropoda) lebih tinggi Kemarau. Tidak struktur komunitas gastropoda antara kemarau hujan. Terdapat sedikit
