KEANEKARAGAMAN DAN KELIMPAHAN POLYCHAETA PADA ZONASI MANGROVE DI PULAU LEPAR KABUPATEN BANGKA SELATAN
Daftar Isi:
- The area of Lepar Island is located in Lepar Pongok Subdistrict, South Bangka Regency, Bangka Belitung Province. Mangrove is a living place for basic biota include Polychaeta. The purpose of this research was to know structure of mangrove comunity, mangrove zonation, diversity and abundance of Polychaeta also the relation between Polychaeta and mangrove. This research has been held on March 2016. The research method used quadratic transect for mangrove sampling and paralon pipe for Polychaeta.The result of environmental parameters showed that the temperature 29,86 – 30,170C, salinity 28,67 – 29,670/00 and pH 7,01 – 7,16. Mangrove of Lepar Island was categorized as medium condition because the average of density value ranged >1000 ind/ha but <1500 ind/ha. There was 2 species of Polychaeta, Nereis sp and Opheliia sp. The highest mangrove density was at seedling level. Pattern of mangrove zonation dominated by Avicennia sp, Rhizophora sp, and Bruguiera sp. The density of mangrove had a low relation with abudance of Polychaeta that R2 = 0,44.
