Mangrove forests are productive habitats and major potential exporters of organic matter nutrients to adjacent habitats. Here we examine the extent which mangrove carbon is transferred intertidal food webs in second largest mangrove-covered area Africa, Guinea-Bissau. Applying stable isotope analysis mixing models, made comparisons at two spatial scales: (1) a large scale, comparing flats with ...

[1] Wetlands represent the largest component of the terrestrial biological carbon pool and thus play an important role in global carbon cycles. Most global carbon budgets, however, have focused on dry land ecosystems that extend over large areas and have not accounted for the many small, scattered carbon-storing ecosystems such as tidal saline wetlands. We compiled data for 154 sites in mangrov...

Herbicides, particularly diuron, were correlated with severe and widespread dieback of the dominant mangrove, Avicennia marina (Forsk.) Vierh. var. eucalyptifolia (Val.) N.C. Duke (Avicenniaceae), its reduced canopy condition, and declines in seedling health within three neighbouring estuaries in the Mackay region of NE Australia. This unusual species-specific dieback, first observed in the ear...

Mangroves in gulf of Kachchh, Gujarat, India has been studied for grain size spectrum and textural parameters namely phi mean, standard deviation, skewness and kurtosis. Grain size spectrum shows a marked variation in the upstream riverine input stretch. Variation of energy conditions is controlled by the fluvial profile in the channel. Textural pattern shows complicated profile as a result of ...

This study concerns the distribution and potential sources of elevated heavy metal concentrations (Cu, Zn, Pb, Cd, As) in surface sediments of the Dongzhai Harbor, Hainan Island,a national important mangrove ecosystem protection area.It was found that the pollution of As may occur occasional biological effect by numerical Sediment Quality Guidelines. Further, Geoaccumulation indices (Igeo) sugg...

Mangrove ecosystem can absorb and store carbon stock in their biomass sediment. This plays an important role the cycle. study aimed to analyze C-organic content organic of sediment, also CO2 absorption. The sediment sampling was conducted Kolaka Coastal line mangroves using a Peat Auger for 1 m depth. Then separated into four layers. samples were oven dried at 50°C week bulk density analysis (S...

The coral reefs, seagrasses and mangroves from the Costa Rican Caribbean coast have been monitored since 1999 using the CARICOMP protocol. Live coral cover at Meager Shoal reef bank (7 to 10 m depth) at the Parque Nacional Cahuita (National Park), increased from 13.3% in 1999, to 28.2% in 2003, but decreased during the next 5 years to around 17.5%. Algal cover increased significantly since 2003...

Four sediment cores were collected from selected locations of Sundarbans mangroves and Hooghly estuary, northeast coast of India to establish (210)Pb geochronology and trace metal distribution in sediments. Core sites were chosen to reflect a matrix of variable anthropogenic input and hydrological conditions. The vertical distribution of (210)Pb(xs) ((210)Pb(total)-(226)Ra) provided reliable ge...

Mangrove is located in the tropical and subtropical regions and brings good services for native people. Mangrove in the world has been lost with a rapid rate. Therefore, monitoring a spatiotemporal distribution of mangrove is thus critical for natural resource management. This research objectives were: (i) to map the current extent of mangrove in the West and Central Africa and in the Sundarban...
