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...
Mangrove forests are coastal ecosystems that found worldwide in tropical and subtropical zones. Oil spill causes damage to these marine ecosystems. The objective of this study is study the oil-degrading bacteria in some mangrove forests that located at Persian Gulf. In this study sediments and plant materials were collected from mangrove forests at Persian Gulf (Minab and Khamir ports). Oil-deg...
Mangrove forests are the most productive and important ecosystems which provide significant ecosystem services, such as carbon sequestration, flood mitigation, water quality protection and a wide range of habitats to support a rich variety of flora and fauna. Remote sensing provides a relatively easy and much less costly approach to monitor the dynamics of mangrove. However, remote sensing of m...
Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production...
In the dwindling natural mangrove today, mangrove reforestation projects are conducted worldwide to prevent further losses. Due to monoculture and the low survival rate of artificial mangroves, it is necessary to pay attention to mapping and monitoring them dynamically. Remote sensing techniques have been widely used to map mangrove forests due to their capacity for large-scale, accurate, effic...
Globally, human activities have led to rapid mangrove degradation. In Vietnam, as across much of coastal South-east Asia, mangroves play a vital role in the livelihoods of coastal rural communities with relatively low levels of development. However, little is known about the precise impact of human activity on the ecosystem services underpinning these livelihoods. This paper analyses the liveli...
Few studies have empirically examined the suite of mechanisms that underlie the distributional shifts displayed by organisms in response to changing climatic condition. Mangrove forests are expected to move inland as sea-level rises, encroaching on saltmarsh plants inhabiting higher elevations. Mangrove propagules are transported by tidal waters and propagule dispersal is likely modified upon e...
Mangrove trees tend to be larger and mangrove communities more diverse in tropical latitudes, particularly where there is high rainfall. Variation in the structure, growth and productivity of mangrove forests over climatic gradients suggests they are sensitive to variations in climate, but evidence of changes in the structure and growth of mangrove trees in response to climatic variation is sca...
Indonesia has a huge potential of mangrove resources. In 2010, the mangrove area was 5,209,543.16 hectares and the area was decline rapidly to 2,496,185 hectares in 2016. This figure shows depletion and degradation of mangrove ecosystem and therefore, the capacities to supply human needs are decline because of the intense pressure from many activities in the development of coastal zone. The dat...
The bacterial communities played important roles in the high productivity mangrove ecosystem. In this study, we investigated the vertical distributions of rhizosphere bacteria from three mangrove species (Bruguiera gymnorrhiza, Kandelia candel and Aegiceras corniculatum) in Beilun Estuary, China using high throughput DNA pyrosequencing of the 16S rRNA gene. Phylogenetic analysis showed that bac...
