Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics-mainly between latitudes 25° N and 25° S [1]. Mangrove plants were comprised of true-mangrove plants and semi-mangrove plants. The true-mangrove plants were woody plants, which only grew in the intertidal zone and couldn’t survive in the land. Semi-mang...

Mangroves are valuable contributors to coastal ecosystems, and remote sensing is an indispensable way to obtain knowledge of the dynamics of mangrove ecosystems. Due to the similar spectral features between mangroves and other land cover types, challenges are posed since the accuracy is sometimes unsatisfactory in distinguishing mangroves from other land cover types with traditional classificat...

Marine protected areas are commonly seen as the most effective strategy for protecting mangroves from external human pressures but little is known about the role of public land-tenure contexts (dense settlements, agricultural or range lands and wild anthromes) on clearing rates, patch properties, and ecological condition. We addressed the following questions using a peri-urban to wild gradient ...

background and objective: bhitarkanika is the mangrove ecosystem of orissa, india. it was not explored before for occur  rence and distribution of streptomyces . with the aim of isolation and characterization of special group of bacteria from this mangrove ecosystem, the present study has been made. materials and methods: isolates of streptomyces were obtained from plant, soil and water collect...

Physiological responses of mangroves to salinity changes in the field are difficult to quantify, partly because it is still not clear whether mangroves utilize mostly surface water, as believed by many researchers based on the shallow distribution of mangrove roots in anaerobic soils. To test this axiom, we analyzed oxygen isotope ratios of possible water sources in different soil layers and st...

Nations Development Programme), and now also involves several other international organisations. MFF focuses on the countries worst hit by the 2004 tsunami, i.e. India, Indonesia, Maldives, Seychelles, Sri Lanka, and Thailand. While highlighting mangroves as an important flagship ecosystem of its efforts in the region, the MFF is also looking at the conservation of other features, including cor...

The 26 December 2004 Indian Ocean tsunami had major effects on coastal communities and ecosystems. An assessment of coastlines after the tsunami indicates that coastal vegetation such as mangroves and beach forests helped to provide protection and reduce effects on adjacent communities. In recent years, mangroves and other coastal vegetation have been cleared or degraded along many coastlines, ...

various coral reef fish species are highly associated with putative nursery habitats like mangroves and seagrass beds during their juvenile life stage (i.e., ‘nursery species’). Little is known, however, of the degree to which they can use other habitat types as juvenile habitat. In this study we investigated whether some nursery species can utilise alternative juvenile habitats when mangroves ...

Mangroves provide valuable ecosystem goods and services such as carbon sequestration, habitat for terrestrial and marine fauna, and coastal hazard mitigation. The use of satellite remote sensing to map mangroves has become widespread as it can provide accurate, efficient, and repeatable assessments. Traditional remote sensing approaches have failed to accurately map fringe mangroves and true ma...

—Mangroves are critically important habitats for fisheries, both for their resident fish, crustacean, and mollusk populations and as nursery grounds for the target species of offshore fisheries. However, the spatial variation in the benefits provided by mangroves to fisheries is poorly understood. Based on expert knowledge of mangrove ecology and fisheries biology, we developed a preliminary mo...
