Modern mangroves are among the most carbon-rich biomes on Earth, but their long-term (≥106 years) impact on the global carbon cycle is unknown. The extent, productivity and preservation of mangroves are controlled by the interplay of tectonics, global sea level and sedimentation, including tide, wave and fluvial processes. The impact of these processes on mangrove-bearing successions in the Oli...

The bioavailability of nutrients in sediments is one of the most important factors controlling ecological and physiological processes in the mangrove ecosystem (Alongi et al. 2002; Feller et al. 2002; Cheeseman & Lovelock 2004; Krauss et al. 2008). Although mangroves are highly productive, they are generally nutrient-deficient, relying on microbial and plant cycling processes for nutrients (Hol...

T ens of millions of tons of CO2 emissions from mangrove deforestation may be avoided each year at an average cost of less than $10 per ton CO2, conclude Siikamäki et al. in their study (1) in PNAS. Avoiding CO2 emission from mangroves would have the beneficial side effect of protecting biodiversity. With careful selection of areas to be protected, increased protection of biodiversity could be ...

heavy metals in the surface sediments of the two coastal ecosystems of cochin, southwest india were assessed. the study intends to evaluate the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index. the inverse relationship of cd and zn with texture in the mangrove sedimen...

The northernmost and most arid mangrove ecosystem of West Africa is found in Mauritania, in the Parc National du Banc d’Arguin (PNBA). The existing global and regional maps of Mauritania’s mangroves have little detail, and available estimates of the mangrove area differ among studies. We assessed the use of automated Remote Sensing classification techniques to calculate the extent and map the d...

This study has determined the relationship and extent of mangrove reduced carbon flow and its contribution to the diet of higher consumers in a nearby seagrass bed using stable isotope techniques. In a seagrass bed approximately 80 m from a riverine mangrove community, detritus from seagrass or other marine sources of carbon such as epiphytes (Stilophora rhizodes) or phytoplankton the major con...

Studies of mangrove population connectivity have focused primarily on global to regional scales and suggested potential for long-distance connectivity, with archipelagos serving as stepping stones trans-oceanic dispersal. However, the contribution propagule dispersal is still largely unknown, especially at local-scale. Identifying fine-scale patterns unique individual island systems important u...

Mangroves around the world settle along coasts and estuaries, where they usually encounter aquaculture effluent that causes eutrophication regulates nitrogen cycle in their ecosystems. Moreover, physical–chemical features of sediment mangrove habitats might be altered by coastal wind, waves, currents more frequently under condition increasing extreme climatic events. These events affect process...
