Mangrove is an important indicator of biodiversity (Feoli, 2001), its conservation is very important to protect the ecological balance of sea and coastline. More than 90% of the mangrove vegetation species of China in Hainan, and they are about half of the world. But, in recent years, some of mangrove forests haven't been protected well, and result in decreasing. How to monitor the dynamic chan...

Mangrove forests are important natural ecosystems due to their ability to capture and store large amounts of carbon. Forest structural parameters, such as canopy height and above-ground biomass (AGB), provide a good measure for monitoring temporal changes in carbon content. The protected coastal mangrove forest of the Everglades National Park (ENP) provides an ideal location for studying these ...

This study provides the first assessment of decadal changes in mangrove extents in Sierra Leone. While significant advances have been made in mangrove mapping using remote sensing, no study has documented long-term changes in mangrove extents in Sierra Leone-one of the most vulnerable countries in West Africa. Such understanding is critical for devising regional management strategies that can s...

Mangrove and saltmarsh communities are essential components of estuarine ecosystems on the NSW south coast. Globally, projected sea level rise under IPCC climate scenarios pose a significant threat to the survival of mangrove and saltmarsh ecosystems. The resilience of mangrove and saltmarsh to the impacts of sea-level rise is dependent upon the maintenance of their elevation with respect to ri...

An attempt was made to establish a mechanistic linkage between chemical speciation of copper and nickel, and their bioavailability in mangrove ecosystem. Kinetic speciation study was performed to determine the concentrations of labile metal-complexes and their dissociation rate constants in mangrove sediments. Concentrations of copper and nickel in the mangrove roots were used as indicators of ...

With the aim of configuring next-generation green data centers, we introduce a new system architecture called “Mangrove” that achieves total optimization by vertically integrating servers, storage drives, networks, middleware, and facilities. Mangrove embodies resource pooling and the offloading of control functions to middleware, which are key concepts of the Next-Generation Green Data Center....

Mangrove forests are one of the most productive and bio-diverse wetlands environments on earth. In Malaysia, Forestry Department of Peninsular Malaysia (FDPM) has always been fully committed to the implementation of the sustainable forest management practices and in line with current concerns such as climate change, conservation of biodiversity and Tsunami, have brought about a heightened expec...

This study investigated changes in landings of all prawns, white prawns (mainly Penaeus merguiensis), mangrove extent, rainfall and the area of shallow water in western peninsular Malaysia. The most important state for both the landings of all prawns and white prawns was Perak where about 50% of all prawns and 35% of white prawns were landed. This is also the state with the largest, and most st...

Gazi Bay, Kenya, covers an area of 18 km2, and its mangroves are degraded. We present a quantitative and qualitative evaluation of the degradation of vegetation structure and dynamics of mangrove communities over a period of 25 yr, using aerial photography in a geographical information system (GIS), combined with ground-truth data for different vegetation layers, and with faunal and environment...

Mangrove forests, distributed in the tropical and subtropical regions of the world, are in a constant flux. They provide important ecosystem goods and services to nature and society. In recent years, the carbon sequestration potential and protective role of mangrove forests from natural disasters is being highlighted as an effective option for climate change adaptation and mitigation. The fores...
