“…Moreover, the biomass value of R. apiculata was comparable with the values recorded elsewhere Table 2. Studies revealed that the variation in above ground biomass depends on species but also on ecological circumstances and geographical location (Komiyama et al, 2008). Furthermore, Komiyama et al (2008) noted that total aboveground biomass of Rhizopora sp.…”

Problem statement: Mangrove forests are found in tropical and subtropical coastal tidal regions. Rhizophora apiculata Blume is one of the most important species in mangrove forest. It is also one of the commercial mangrove timber species in Asia-Pacific region which dominates large areas of mangrove in this region. In order to understand forest ecosystem characteristics and to establish the proper management system, a precise estimation of biomass is necessary. The objective of this study is to quantify the aboveground biomass production and stem volume of R. apiculata in Awat-Awat mangrove forest, Sarawak. Approach: Seven representative trees were used in this study for sampling from February 2011 to March 2011. Allometric relationships were examined using either independent variable Diameter (D) or combination of quadratic of D and Height (D 2 H). Results: The best fit of allometric equations were developed from the combination of quadratic of D and H (y = 0.055×0.948, R 2 = 0.98) which is more recommended to estimate biomass and stem volume of R. apiculata in Awat-Awat mangrove forest, Sarawak. Total aboveground biomass and stem volume of R. apiculata were 116.79 t h −1 and 65.55 m 3 h −1 , respectively. Conclusion: Aboveground biomass and stem volume is closely related with tree diameter and height which indicates that aboveground biomass and stem volume will increase with increasing diameter and height of R. apiculata.

“…Mangrove forests are important because they have the ability to improve ecological aspects such as organic carbon dynamics (Flores-Verdugo et al 1987, Bashan and Holguin 2002, Kristensen et al 2008) and primary productivity (Holguin et al 2001, Dittmar et al 2006, and they provide protection against hurricanes and tropical storms (Raven et al 1992, Gilman et al 2008, Komiyama et al 2008. Despite their ecological importance, mangrove forests around the world are constantly exposed to anthropogenic disturbances such as port development in the coastal zone, expansion of the agricultural frontier, and aquaculture expansion (Duke et al 2007, Polidoro et al 2010, Spalding et al 2010.…”

Growth of three subtropical mangrove species in response to varying hydroperiod in an experimental tank

ABSTRACT. The effect of hydroperiod on the survival and growth of Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle seedlings under experimental conditions was investigated using a simulated tidal system. Seedlings of the three mangrove species were grown at four inundation levels. All levels were flooded every 12 h in order to create a simulated semi-diurnal tide cycle (i.e., two high tides and two low tides per day). Based on the hydroperiod for the study area, level 1 was flooded for 10 h, level 2 for 6 h, level 3 for 2 h, and level 4 for 6 min. After 570 days, the results showed that R. mangle presented the highest growth at level 1 and the lowest growth at level 4. The optimal growth of L. racemosa occurred at levels 2 and 3, but all the seedlings died at level 1, indicating that this species is highly sensitive to tidal regimes. Compared to L. racemosa and R. mangle, A. germinans had a moderate growth rate at all four levels. Mangrove growth differentiations were more prominent at levels 1 and 3, where the three species showed very different growth patterns. Studies of optimal growth using hydroperiod experiments are important in order to understand the physiological responses of mangrove forests to a possible sea level rise in the next decades, especially in subtropical environments where they are constantly exposed to stress.Key words: hydroperiod, Avicennia germinans, Laguncularia racemosa, Rhizophora mangle. RESUMEN.Se investigó el efecto del hidroperiodo en el crecimiento y supervivencia de plántulas de Avicennia germinans, Laguncularia racemosa y Rhizophora mangle bajo condiciones experimentales por medio de un simulador de mareas. Se colocaron plántulas de las tres especies a cuatro diferentes niveles de inundación durante 12 h para simular un ciclo de marea semidiurna (i.e., dos mareas altas y dos mareas bajas por día). Con base en el hidroperiodo de la zona de estudio, el nivel 1 estuvo inundado por 10 h, el nivel 2 por 6 h, el nivel 3 por 2 h y el nivel 4 por 6 min. Después de 570 días, los resultados mostraron que R. mangle presentó el mayor crecimiento en el nivel 1 y el menor crecimiento en el nivel 4. El crecimiento óptimo de L. racemosa fue en los niveles intermedios 2 y 3, pero todas las plántulas murieron en el nivel 1, lo cual nos indica que esta especie es altamente sensible a periodos prolongados de inundación. Comparado con L. racemosa y R. mangle, A. germinans presentó un crecimiento moderado en los cuatro niveles. La diferencia en el crecimiento de los manglares fue más prominente en los niveles 1 y 3, donde las tres especies mostraron patrones muy diferentes. Los estudios sobre el crecimiento óptimo mediante simuladores de marea son importantes para entender la respuesta fisiológica de los bosques de mangle a un posible incremento en el nivel del mar en las próximas décadas, especialmente en ambientes subtropicales donde el nivel de estrés es alto.

“…The ratio of aerial parts to root parts in several mangroves was found to vary from 1.1 to 4.4, indicating that a larger amount of biomass is allocated to below ground (Komiyama et al 2008).…”

“…Generally, mangrove ecosystems have a large stock of roots with high root biomass, which provides a large amount of organic matter due to the slow decomposition in the anoxic conditions and periodic flooding of the soil (Komiyama et al 2008). Among the root systems of mangroves, fine roots (roots < 2mm of diameter; Rosado et al 2011) play an important function in nutrient cycling because they make a great contribution to the dynamics of belowground phytomass.…”

-(Description of the soil and root biomass of two subtropical mangroves in Antonina and Guaratuba Bay, Paraná State, Brazil). The soil of the mangroves influences the root anchorage and the nutrition processes of the plant community. This study evaluated the relationships among edaphic conditions, volume and biomass of roots, and tree structure of two mangroves in Paraná State. Five soil cores of 50 cm depth were collected from each mangrove for physicochemical analysis. Organosoil thiomorphic salic sodic predominated in Antonina Bay, while in Guaratuba Bay were observed the Gleysoil thiomorphic salic sodic and the Organosoil thiomorphic salic sodic. Fifteen root samples were collected from each mangrove area for root volume and dry mass analysis'?'. The higher values of root mass were found in Guaratuba Bay. The chemical analysis of the soil showed no correlation between biomass and root volume. The high coefficients of variation attested the high heterogeneity in the root distribution in both areas. However, in the Guaratuba Bay, root mass and volume are higher due to the textural composition of the soil and higher tree density.
