The stem carbon content can be easily estimated from this model by using an easily measurable tree parameter. Therefore, it is very important to measure the carbon content of the tree stems, in order to estimate the role of a particular tree species in removal of excessive carbon dioxide from the atmosphere. The correlation between the stem carbon content and the individual tree parameters was assessed using person’s correlation analysis. However, considering the current global warming conditions in the world, it is important to consider the carbon sequestration capacity of the selected species for replantation as the mangrove plants are considered to be excellent carbon dioxide removers from the atmosphere [11, 12]. Subscribe today. Determination of the stem carbon content of individual species is very important and can play a key role when assessing the carbon sequestration capacity of the ecosystems. Rhizophora mucronata has a developed strong root system, which can hold the sediments tightly, and thereby, they can serve as very important coastline stabilizers to protect the coastal ecosystems from strong storms, waves, and coastal erosion. This study was conducted in a major mangrove conservation forest, The Kadol Kale mangrove forest located in Sri Lanka. Menurut Hughes (2002) sistem kekebalan tubuh rentan terhadap kerusakan oksidatif, hal ini disebabkan karena sel imun memproduksi komponen-komponen reaktif sebagai bagian dari mekanisme pertahanan tubuh.Efektivitas kerja sistem imun sangat bergantung pada komunikasi antar sel melalui reseptor … Rhizophora mucronata, a dominant species in the Kenyan mangroves (UNEP, 2001), has been reported on several occasions to form wood which completely lacks growth ... of the tree, but at 130 cm height above ground level. 079 45' 29.9'' E), southeast coast of India was selected for pruning experiment. On the fringes of the sea 10 or 15 metres (33 or 49 ft) is a more typical height. The most common tropical mangrove genera include Avicennia, Rhizophora, Bruguiera, and Sonneratia. Most mangrove forests are located in tropical areas, although there are some expansions into subtropical regions as well. The Mean Annual Increment (MAI) of stem diameter and height of R. mucronata and A. marina seedlings is shown on the Table 4. The VIF > 5 suggests that the regression coefficient is poorly estimated due to severe multicollinearity, and 1 < VIF < 5 suggests that regression coefficient is poorly estimated due to severe multicollinearity. Therefore, it is recommended to extend this allometric equation development method to estimate the stem carbon content of other common tropical mangrove species in order to get an accurate estimate on the contribution of tropical mangrove stem carbon storage capacity for mitigation of global warming. Propagules, those about to detach from trees were collected in August, 2013 in Pambala lagoon, Sri Lanka (7°34’N, 79°48’E) to use in the experiment. In Rhizophora mucronata, the bacterial treatment increased the shoot height growth at different levels of salinity. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. R. R. Twilley, R. Zimmerman, L. Solorzano et al., “The importance of mangroves in sustaining fisheries and controlling water quality in coastal ecosystems,” Tech. W. M. Dimuthu Nilmini Wijeyaratne, Pawani Madhushani Liyanage, "Allometric Modelling of the Stem Carbon Content of Rhizophora mucronata in a Tropical Mangrove Ecosystem", International Journal of Forestry Research, vol. Generally, mature trees are expected to have long carbon residence time. HabitatInhabits the intertidal wetland zone, 0–6 m (0–20 ft) elevation between mean sea level and highest tides, with variable rainfall. The residual diagram showed a random pattern indicating that the model can be proved to use in the real world (Figure 2). Classification. The data are presented as mean ± standard deviation. The black mangrove, usually of moderate height, sometimes grows 18 to 21 metres (59 to 69 feet) tall. rivers. Rhizophora mucronata Lam. Click on a scientific name below to expand it in the PLANTS Classification Report. A diameter tape was used to measure the diameter at breast height (DBH) of each tree, and the clinometer method was used to measure the total tree height, tree crown height, and merchantable stem height. Leaf area was not statistically significant. 2020, Article ID 8849413, 6 pages, 2020., 1Department of Zoology and Environmental Management, Faculty of Science, University of Kelaniya, Dalugama, Kelaniya, Sri Lanka. Tree allometry is an important tool for estimating tree weight from independent variables such as trunk diameter, tree height, crown height, total height that are easily measurable in the field. We therefore selected three species of mangroves with different propagule size: Avicennia marina (2.5 ± 0.3 cm), Bruguiera gymnorrhiza (16 ± 2 cm) and Rhizophora mucronata (36 ± 3 cm). The present study identifies that the allometric model, Ln C = −2.403 + 2.247 Ln DBH as the best fit and practical model to estimate the stem carbon content of Rhizophora mucronata. Considering the diameter at breast height of all the trees, the trees were grouped into classes as follows: Diameter class 1:4.0 < DBH ≤ 6.0 cm Diameter class 2: 6.0 < DBH ≤ 8.0 cm Diameter class 3: 8.0 < DBH ≤ 10.0 cm Diameter class 4: 10.0 < DBH ≤ 12.0 cm Diameter class 5: 12.0 < DBH ≤ 14.0 cm Diameter class 6: 14.0 < DBH ≤ 16.0 cm. Therefore, total height, stem height, and crown height were eliminated to refit the model. The values within the parentheses indicate the range of each parameter. The present study can be considered as the initial attempt to use a non-destructive method to construct an allometric equation to predict the stem carbon content of Rhizophora mucronata in a tropical conserved mangrove forest. The height and growth of the Red Mangrove is in direct relation with the location where it grows and the existing growth conditions. The data were tested for normality using the Anderson Darling test, and the nonnormalized data were log transformed as appropriate. The measured stem carbon content of the Rhizophora mucronata trees used for model validation ranged from 1.3 kg to 4.3 kg and their predicted values ranged from 1.3 kg to 3.6 kg. B. S. Sabin, “Relationship between allometric variables and biomass in Western Juniper (Juniperus Occidentalis),” Oregon State University, Corvallis, Oregon, 2008, M.S. Furthermore, Rhizophora mucronata is recognized as a species with a considerable economic importance as it provides natural products such as charcoal, wild honey, and timber, food, and medicinal element to the mangrove forest associated residents to improve the quality of their livelihoods [9, 10]. The basic concept of allometric relationships is that the growth rate of one or more measurements of the tree is proportional to that of other parameters [22]. West, “Scaling in biology,” in, B. Lippke, J. Wilson, J. Meil, and A. M. Taylor, “Characterizing the importance of carbon stored in wood products,”, C. A. This carbon is fixed by photosynthesis and comparatively high carbon content can be stored in the stem of the trees compared to the leaves. Red mangrove is a tree with a glossy green, quite compact crown; it can grow 8 - 30 metres tall. The height and growth of the Red Mangrove is in direct relation with the location where it grows and the existing growth conditions. Previous studies conducted in this part of the country to assess the mangrove carbon sequestration capacity have used destructive methods [31, 32]. Seventy individual trees of Rhizophora mucronata were selected from the study area based on purposive sampling. MAI of stem diameter and height of R. mucronata and A. marina seedlings Species Spacing (m) MAI Stem Diameter (mm/yr) Height (cm/yr) Rhizophora mucronata 1 x 1 20,94 a 19,23 a 0,5 x 0,5 20,82 a 15,78 a The present study was conducted to develop an allometric model to determine the stem carbon content of Rhizophora mucronata in a conserved tropical mangrove ecosystem. The tallest trees are closest to the water and shorter trees are further inland. mangrove area of Muara Angke Jakarta using Rhizophora mucronata seedlings with spacings of 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 m. The leaves are elliptical and usually about 12 centimetres (4.7 in) long and 6 centimetres (2.4 in) wide. from demarcated plots of using plot-less methods. The tree has a large number of aerial stilt roots buttressing the trunk. Only 75% of data were used in construction of the model while other 25% of data were used in model validation. The transformed data were used in model construction, evaluation, and validation. The descriptive statistics of the tree parameters of, The stem carbon content data are presented as mean ± standard deviation. The Archimedes displacement principle was used to measure the initial volume of the collected core samples. There has been no specific study to highlight why R. mucronata became the dominant species of the The tallest trees are closest to the water and shorter trees are further inland. Figures 4–5 show the height and dbh distributions of mangrove species in meters and centimeters respectively.
