A study on antibiotic resistance of heterotrophic bacteria and physicochemical characteristics of water and sediment in mangrove environment of Muthupettai, Southeast coast of India was carried out during April 2006 March 2007. Six stations in and around the mangrove sites were selected for sampling and the following parameters were recorded at monthly intervals temperature, pH, salinity, disso...

Airborne light detection and ranging (LIDAR) measurements derived before and after Hurricanes Katrina and Wilma (2005) were used to quantify the impact of hurricanes and lightning strikes on the mangrove forest at two sites in Everglades National Park (ENP). Analysis of LIDAR measurements covering 61 and 68 ha areas of mangrove forest at the Shark River and Broad River sites showed that the pro...

Mangrove communities are tropical systems which have fewer species than tropical forests, especially in Latin America and display a single architecture, usually lacking the various strata commonly found in other forest ecosystems. The identification of mangrove communities by orbital data is not a difficult task but the most interesting challenge is to identify themselves by the dominant specie...

Mangrove communities comprise a group of biotic components, including plants, animals and microbial organisms, that are highly adapted to intertidal environmental conditions. However, none of these can be identified as a community in a mangrove ecosystem without the actual mangrove plants (trees and shrubs), implying that the true mangrove vegetation is the major constituent of the ecosystem. M...

BACKGROUND Mangrove forests are of global ecological and economic importance, but are also one of the world's most threatened ecosystems. Here we present a case study examining the influence of the rhizosphere on the structural composition and diversity of mangrove bacterial communities and the implications for mangrove reforestation approaches using nursery-raised plants. METHODOLOGY/PRINCIP...

Mangrove forests, important tropical coastal habitats, are in decline worldwide primarily due to removal by humans. Changes to mangrove systems can alter ecosystem properties through direct effects on abiotic factors such as temperature, light and nutrient supply or through changes in biotic factors such as primary productivity or species composition. Despite the importance of mangroves as tran...

Offshore catches of banana prawns, Penaeus merguiensis, are correlated with the extent of mangrove forests. However, recent evaluation has questioned whether the apparent relationship between juvenile penaeids and mangroves reflects specific utilisation of mangroves or just the use of shallow, organically rich, muddy habitats. We investigated this by focussing on juvenile P. merguiensis within ...

 Itacorubi, Ratones, Rio Tavares and Saco Grande are natural mangrove forests in the western part of Santa Catarina Island, in southern Brazil. Thirty-three basidiomycetes were identified during a survey of xylophilous basidiomycetes in these mangrove forests from May 2005 to August 2006. The species are distributed among 9 families and 24 genera. Fifteen species are new records from mangrove ...

The distribution of selected aromatic compounds and microbiology were assessed in superficial sediments from Suruí Mangrove, Guanabara Bay. Samples were collected at 23 stations, and particle size, organic matter, aromatic compounds, microbiology activity, biopolymers, and topography were determined. The concentration of aromatic compounds was distributed in patches over the entire mangrove, an...

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...
