“…Differences in leaf quantity are known to affect decomposition rates [5,21,36]. Different decay constant had been recorded for different mangroves species in different geographical location and in different regions (Table II), probably due to the differences in the nitrogen and tannin contents [6,13,35,37]. Plant material with a higher lignin contents or a higher C:N ratio are more refractory, and thus decompose more slowly than plant materials with relatively low lignin contents or a relatively low initial C:N ratio [13,21,35].…”

“…The fallen mangrove litter on the forest floor is decomposed by the bacterial action and other organisms, as well as acted upon by physical, chemical and biological processes [1][2][3][4][5][6], and generate a continuous source of nutrients in mangrove ecosystem [7][8][9][10]. These nutrients ions (most importantly the ammonium, nitrate, nitrites) are finally available for primary production and this in turn supports a wide variety of consumers [5][6][11][12]. The process of decomposition of mangrove leaves can be divided in three phases [3].…”

Leaf decomposition of Avicennia marina (Forskal) Vierh in Denkschr and Rhizophora mucronata (Poiret) was studied in situ using litterbags in Hajambro creek, Indus delta. A single exponential model was presented, which best described the rate of decomposition for both the species. The rate of decomposition was species specific, A. marina leaves decomposed slower than the R. mucronata (p<0.001). The time in days required for 50% loss of the initial dry mass (t1/2) was 49.55 days for the A. marina and 44.43 days in case of R. mucronata . The organic content in the leaves was high initially but decresed gradually during decomposition, which is negatively correlated with inorganic contents. This study will help in the management and conservation of mangrove ecosystem of Hajambro creek, Indus delta, Pakistan.

“…La importancia de los manglares puede estar relacionada con una amplia variedad de factores, los cuales incluyen una alta tasa de descomposición por caída de hoja (Flores-Verdugo et al, 1987;Wafar et al, 1997;Kristensen et al, 2008), ciclo de nutrientes (Feller et al, 1999;Bashan y Holguin, 2002), interacciones de fauna relacionadas con funciones del ecosistema (Cannicci et al, 2008;Nagelkerken et al, 2008), almacenamiento de carbono (Donato et al, 2011), cambio climá-tico (Gilman et al, 2008), producción primaria (Komiyama et al, 2008;Raven et al, 2012), zona de protección de tormentas tropicales y huracanes (Kovacs et al, 2004), y proveen una fuente renovable importante para pesquerías locales (Walters et al, 2008). A pesar de su importancia ecológica, los bosques de manglar han presentado una perdida global de 30-50% durante la última mitad del siglo pasado (Donato et al, 2011), principalmente debido al desarrollo de la costa y a la acuicultura (Valiela et al, 2001;Duke et al, 2007;Polidoro et al, 2010).…”

Antecedentes y Objetivos: Los eventos fenológicos en manglares suelen estar influidos por factores como la salinidad del agua, fotoperiodo y/o temperatura ambiental. Esto se ha documentado principalmente para especies de la familia Rhizophoraceae y Acanthaceae; sin embargo, son limitados los estudios accesibles para la familia Combretaceae, p. ej. Laguncularia racemosa.Métodos: Se colectaron durante un año, mensualmente, de tres a cuatro hojas del antepenúltimo y penúltimo entrenudo de las ramas de 10 árboles de Laguncularia racemosa. La colecta de hojas se realizó teniendo en cuenta ocho etapas fenológicas. Los nutrientes analizados en las hojas fueron: N total, PO, K+, Ca2+, Mg2+, SO, Na+, Fe2+, Cu2+, B (H3BO3), Mn2+ y Zn2+. Adicionalmente, 10 muestras de agua intersticial (para medir iones mayores) y sedimento (para medir el pH y cuantificar el contenido de materia orgánica) se tomaron a una profundidad de entre 0.3 a 0.6 m.Resultados clave: Los nutrientes K+, Ca2+, Fe2+, Mg2+, y N total presentaron valores máximos a lo largo del desarrollo de la brotación vegetativa hasta el desarrollo de “frutos”, lo cual significa que la mayor importancia de estos nutrientes es en la producción de “frutos”. El Na+ mostró su mayor concentración (22.8 g kg-1) en la fase de inicio de floración y la mínima durante la quiescencia (8.7 g kg-1). En contraste, el SO, PO, Cu2+, B (H3BO3), Zn2+ no presentaron diferencias. Finalmente, el Mn2+ presentó 109 mg kg-1 al final de la brotación vegetativa y 34 mg kg-1 en la madurez y caída de “frutos”.Conclusiones: En la absorción de nutrientes son importantes las etapas fenológicas y las condiciones climáticas locales.

“…Mangroves provide food sources for marine animals and act as shelter and a nursery ground for fish larvae and other important economic aquatic species such as sea bass, grouper, crab and shrimp (Ronnback, 1999;Kathiresan, 2010). Mangrove trees also help nourish soil organic matter, recycle nutrients and protect shoreline from erosion and tsunamis (Wafar et al, 1997;Osti et al, 2008;. In terms of the economy, mangroves can be used as a renewable resource for charcoal production that generates income for local inhabitants (Bandaranayake, 1998;Kridiborworn et al, 2012).…”

Abstract. Mangrove plantation for renewable energy production has an important economic value for Thai inhabitants. Planted mangroves may also serve as valuable areas for biodiversity. We aimed to investigate benthic community structure and estuarine environment in mangrove plantation sites (young, intermediate, mature sites and a semi natural mangrove forest) in Samut Songkram province. The mangrove plantation is a monoculture of Rhizophora apiculata compared with a semi natural mangrove forest where 5 species of trees were recorded. Values of mangrove height and diameter at breast height (DBH) increased with the age of the mangrove plantation forests. Overall, the parameters reflected good water quality conditions (temperature 30.75-32 0 C; pH 6.69-7.73; salinity 16.33-21.66 ppt; DO 3.45-4.57 mg/l). Nutrient concentrations and BOD were rather low indicating less impact from nutrient sources. In term of biodiversity, phytoplankton and zooplankton appeared to be greater in younger mangrove plantation sites. Intertidal benthic macroinvertebrate communities tended to increase with the age of the plantation site and invertebrate assemblages have developed through time. Hence, it could be stated that mangrove plantation used as charcoal production not only generates income for the local people but also plays an important role in estuarine ecosystems as the crucial habitat for benthic macroinvertebrate species.
