Abstract

Abstract. Analuddin K, Kadidae LO, Haya LOMY, Septiana A, Sahidin I, Syahrir L, Rahim S, Fajar LOA, Nadaoka K. 2020. Aboveground biomass, productivity and carbon sequestration in Rhizophora stylosa mangrove forest of Southeast Sulawesi, Indonesia. Biodiversitas 21: 1316-1325. This study was aimed at analyzing the trends of aboveground biomass (AGB), productivity and carbon sequestration of Rhizophora stylosa Griff. forest in Rawa Aopa Watumohai National Park (RAWNP), Southeast Sulawesi, Indonesia. The DBH was the best predictor for partial and whole AGB of R. stylosa trees. The mean AGB was 562.76 ton ha-1. The yearly biomass increment of living trees, biomass increment of whole stands, standing dead biomass, and litterfall in R. stylosa forest were estimated as 52.87, 50.09, 2.78 and 12.00 ton ha-1, respectively, while its net primary production was about 64.88 ton ha-1 yr-1 indicating higher mangrove productivity. The total carbon stock in R. stylosa forest was 264.50 ton ha-1, while the annual net carbon budget, carbon gain and carbon input in R. stylosa forest was 23.54, 24.85 and 5.64 ton ha-1. However, the total CO2 stored in R. stylosa forest was 969.83 ton ha-1, while the annual of net CO2 uptake, CO2 gained and CO2 input was 86.33, 91.12 and 20.86 ton ha-1. The higher carbon sequestration and CO2 uptake in R. stylosa forest indicate its significant role in the global carbon accumulation and reducing atmospheric CO2.

Isolation and enzyme bioprospection of bacteria associated to Bruguiera cylindrica, a mangrove plant of North Sumatra, Indonesia

“…Mangrove plants may alter microorganisms assemblage by developing specific adaptations to extreme environmental conditions, such as high temperatures, salinity fluctuations, tides, toxic pollutants, and serves as a biofilter of heavy metal pollutants [ [32] , [33] , [34] ]. In addition, the absorption of CO 2 carbon in mangrove forests showed significant benefits in global carbon accumulation and reduces atmospheric CO 2 [ [35] , [36] , [37] ]. Recently, halophilic microorganisms, especially bacteria, have attracted the attention of many researchers to find novel enzyme sources, since these could be relatively more stable and active than other enzymes derived from plants or animals [ 38 , 39 ].…”

Analisis Vegetasi, Estimasi Biomassa dan Stok Karbon EkosistemMangrove Pesisir Kecamatan Latambaga, Kabupaten Kolaka

“…Selain itu, ekosistem mangrove juga memiliki peranan yang sangat penting dalam memitigasi dampak perubahan iklim (Sharma et al, 2019;Indrayani et al, 2021). Analuddin et al, (2020) menyatakan bahwa ekosistem mangrove berperanan penting dalam penyuplai O 2 , dan mengabsorbsi CO 2 dari atmosfer. Lebih lanjut, Alongi & Mukhopadhyay (2014), menyatakan bahwa ekosistem ini mampu menyerap dan menyimpan banyak karbon.Karbon yang tersimpan di ekosistem mangrove ini tersimpan dalam bentuk biomassa yang dikenal dengan istilah karbon biru.…”

“…Mangrove berperanan penting dalam penyuplai O 2 , penyerap dan penyimpan CO 2 (Analuddin et al, 2020) dan mampu menyimpan karbon dengan jumlah yang banyak (Alongi & Mukophadhyay, 2015;Adame et al, 2017). Simpanan karbon dalam suatu vegetasi mangrove menggambarkan seberapa besar kapasitas vegetasi mangrove tersebut dalam menyerap dan menyimpan karbon dalam bentuk biomassa vegetasi.…”

Diversity, biomass, covers, and NDVI of restored mangrove forests in Karawang and Subang Coasts, West Java, Indonesia

“…In Panabo Park, Philippines, Alimbon and Manseguiao (2021) have measured the biomass for Avicennia marina, Rhizophora mucronata and Sonneratia alba of 46.30 mg ha -1 , 2.89 mg ha -1 and 27.98 mg ha -1 respectively. In the study of Analuddin et al (2020), the measured R. stylosa biomass in Southeast Sulawesi ranged from 21.19 to 562.76 mg ha -1 . While, Zulhalifah et al (2021), have recorded the biomass for A. marina, Rhizophora apiculata and Sonneratia caseolaris of 36.72 mg ha -1 , 148.92 mg ha -1 , and 127.76 mg ha -1 respectively in Lombok.…”
