“…Mechanical fragmentation resulting from the activities of the macrofauna allows for the release of soluble molecules and greatly increases the surface area of the leaves available for colonization by microorganisms, which accelerates their decomposition [6]. Litter leachates were identified as a significant food source for microbial communities in coastal waters [7]. Furthermore, there were differential decomposition rates between A. marina and K. obovata leaves, highlighting the species-specific variations in litter decomposition within mangrove ecosystems [33].…”

“…The nutrients returned by mangroves through litter are significant to the energy flow and material circulation of the wetland ecosystem. A mangrove leaf litter incubation experiment in controlled environmental conditions revealed the role of leaf litter leachates as a significant important food source to microbial communities in coastal waters and a potential carbon sequester through long-term burial in mangrove soil [7]. It is estimated that mangrove litter accounts for approximately 30%-60% of the total primary production in the mangrove ecosystem; deciduous leaves make up roughly 60%-79% of the entire litter [1,8].…”

The decomposition of mangrove litter plays a crucial role in material circulation and energy flow within mangrove forests. Evaluating the decomposition-based variation in biogenic elements in litter is important for improving our understanding about their biogeochemical cycling in ecosystems. The main objective of this study was to examine the interaction effect during the decomposition process of mixed Kandelia obovata and Avicennia marina litter. Variations in C and N were also determined in the decomposing leaf litter mixtures. Our findings revealed that the decomposition rates were faster in summer than in winter, and increased with the proportion of A. marina litter. After 35 days of decomposition in summer, the remaining weights for different proportions of K. obovata (KO) and A. marina (AM) were 22.9% (KO:AM = 1:2), 27.2% (KO:AM = 1:1), and 31.2% (KO:AM = 2:1), respectively. Similarly, after 49 days of decomposition in winter, the remaining weights for the different KO:AM proportions were 27.7%, 35.4%, and 44.0%, respectively. Additionally, the decomposition of mixed K. obovata and A. marina litter had an influence on C content and N release dynamics. These results provide a scientific basis for understanding the decomposition of mixed mangrove litter and its implications for material circulation and energy flow within these ecosystems.

Abstract. Wintah, Kiswanto, Hilmi E, Sastranegara MH. 2023. Mangrove diversity and its relationships with environmental conditions in Kuala Bubon Village, West Aceh, Indonesia. Biodiversitas 24: 4599-4605. Mangrove ecosystem plays various ecological and socio-economic roles. Indonesia has the largest extent of mangrove forest one of which is located in West Aceh Regency, Aceh Province. The aim of this study was to assess the diversity and structure of mangrove forest in Kuala Bubon Village, West Aceh, and to analyze the relationships between the existence of mangrove species and the environmental conditions. Field survey was conducted from May to August 2022 using plot sampling method on three stations representing various habitat characteristics. Vegetation sampling using a 10 x 10 m2 plot as well as measurement on physical parameters (pH, salinity, and temperature) and chemical parameters (sediment texture and organic carbon content) were conducted. The relationship between the presence of mangrove species and the environmental parameters was analyzed using Principal Component Analysis (PCA). The result of vegetation sampling recorded 6 mangrove species, i.e., Rhizophora stylosa Griff, Sonneratia alba Sm, Avicennia marina (Blume), c, and Sonneratia caseolaris (L) Engl. This study revealed that the presence of Rhizophora stylosa Griff was related to the conditions of the clay substrate, pH and temperature values. Meanwhile, the existence of Rhizophora apiculata Blume, Rhizophora mucronata Lamk, Sonneratia alba Sm, Sonneratia caseolaris (L) Engl, and Avicennia marina (Blume) was related to the conditions of the silt substrate, diameter and salinity. Based on the results of relationship analysis, silt substrate and salinity have a correlation to maintain the mangrove ecosystem.

“…The quality and quantity of mangrove leaf litter will determine the energy available to the decomposing organisms. Decomposer organisms with a lot of energy will be more active in breaking down mangrove leaf litter (Mamidala et al, 2023). Several factors, including mangrove type and leaf thickness, influence the quality of mangrove leaf litter.…”

Mangroves are the dominant ecosystem in coastal areas and estuaries and one of the most productive ecosystems in the world. Mangroves are an essential component in a complex food chain and have the potential for the life of various marine and terrestrial biotas, microorganisms, and macroorganisms. The decomposition of mangrove leaf litter by fungal bacteria produces nutrient source that is beneficial for fish, shrimps, and crabs. This study discusses the production and decomposition rate of mangrove leaf litter in the mangrove ecosystem of Muara Pagatan, South Kalimantan. With transect and litter trap methods, litter production during the observation ranged from 218.51 - 858.28 g/m2/45day. Of the four types of mangroves found, the highest litter production was found in Rhizophora mucronata mangrove species at 858.28 g/m2/45day, followed by Bruguiera gymnorrhiza species at 268.52 g/m2/45day, and the lowest litter production was Avicennia marina mangrove species at 222.9 g/m2/45day and Sonneratia alba at 218.51 g/m2/45day. The remaining dry weight during observation ranged from 1.06 g - 2.46 g. In sum, the highest litter productivition and decomposition rate was found in Rhizophora species and litter was not completely decomposed after 45 days.
