An ecomorphodynamic model was developed to study how Avicennia marina mangroves influence channel network evolution in sandy tidal embayments. The model accounts for the effects of mangrove trees on tidal flow patterns and sediment dynamics. Mangrove growth is in turn controlled by hydrodynamic conditions. The presence of mangroves was found to enhance the initiation and branching of tidal chan...

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...

Studies on actinobacteria of marine habitats gaining international importance due to its proven abilities of novel compound production. Information on actinobacteria of the mangrove environments is less and hence the present study was carried out in the different mangrove environment of Bhitarkanikka, Orissa. A total of 116 actinobacterial colonies were recorded from 30 mangrove and marine sedi...

introduction persian gulf is a warm, hypersaline, shallow and semi-enclosed sea with low hydrodynamic energy and ideal conditions for deposition of particle materials. qeshm island is the largest island of persian gulf, in the mouth of strategic hormoz strait. every day, many tankers and ships that transport oil production of persian gulf throughout the world, cross near this island. thus, qesh...

A long-term goal of our sediment transport and deposition investigations is to link sediment-transport processes to the formation and preservation of event beds in sediment deposits. The general aim of this project is to investigate how forcing processes affect the sediment-transport dynamics that act to effect the delivery and retention of fine-grained sediment through tidal rivers and in shal...

In tropical mangroves, brachyuran crabs have been observed to consume high percentages of leaf litter production. However, questions concerning their ability to assimilate this low-quality food remain, as stable isotope analysis of C and N does not seem to support assimilation. Individuals of the common eastern Australian mangrove grapsid Parasesarma erythodactyla feeding on a mangrove leaf lit...

Mangroves play an important role in the storage of carbon (C) and nitrogen (N) within estuarine systems, yet are being lost at an alarming rate throughout the tropics. In contrast, temperate mangroves have increased in area at many locations in recent decades. Field surveys, sediment sampling, allometry, and C and N analysis were used to determine total C and N stocks in five temperate Avicenni...

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...

Plants ecosystems are a habitat for a wide variety of species, some occurring in high densities and provide food and shelter for a large number of commercially valuable finfish and shellfishes. They are productive habitats and support coastal fisheries [1]. The mangrove forests are extremely important coastal resources, which are vital for socioeconomic development of the region. As a detritus-...

The stratified distribution of bacterial and archaeal communities has been detected in many sediment profiles from various natural environments. A better understanding of microbial composition and diversity pattern in coastal mangrove wetlands in relation to physicochemical and spatial-temporal influences could provide more insights into the ecological functions of microbes in coastal wetlands....
