Carbon policy is a fascinating topic in geography and political ecology, because carbon is a new exchangeable good, which links the local to the international arenas through a complex set of instruments, norms, and institutions. In this paper, after explaining my theoretical and conceptual framework rooted in Africanist geography and currents of political ecology, I analyze the responses of loc...

The aim of this research was to evaluate the effect of sediment composition on methane (CH4) dynamics in sediments of different areas in the transition zone between a mangrove and the sea. This research was conducted in a mangrove at Coroa Grande, on the southern coast of Rio de Janeiro. Samples were collected at three stations: (1) region colonised by Rhizophora mangle L. on the edge of the ma...

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...

Shrimp farming is a sufficiently large and mature industry to have an effective range of antimicrobial agents for most bacterial diseases in shrimp culture. However, at present, there exists great concern over the widespread use of antibiotics in aquaculture, which may result in residue of antibiotics in water and mud, and subsequently, the development of antibiotic resistance in bacteria in th...

We studied the physiological differences between sun and shade seedlings of Rhizhophora mangle, the red mangrove. Using the seedlings and their leaves, five experiments were made to determine whether true adaptations were available to shade seedlings to cope with higher stress. The reason why the shade seedlings were in higher stress is because they have to deal with the salt and intense compet...

BACKGROUND Mangroves are transitional coastal ecosystems in tropical and sub-tropical regions and represent biologically important and productive ecosystems. Despite their great ecological and economic importance, mangroves are often situated in areas of high anthropogenic influence, being exposed to pollutants, such as those released by oil spills. METHODOLOGY/PRINCIPAL FINDINGS A microcosm ...

a r t i c l e i n f o Keywords: Mangrove Restoration programs Choice experiment Willingness to pay Brazil Mangrove forests are under considerable pressure in many developing countries and Brazil is not an exception to this problem. We investigate preferences for the restoration of mangrove areas in Brazil, using a choice experiment that varies the level and time of restoration. By interacting t...

Abstract Rabbits are a potential livestock commodity to supply quality meat with higher protein and lower fat cholesterol content than other meat. Helminthiasis is parasitic worm infection that has imposed economic loss involving some risk factors. This study aimed investigate the helminthiasis cases in both upland lowland areas, as well their factors on of rabbit farming. A total 192 samples w...

Mangrove ecosystems help mitigate climate change, are highly biodiverse, and provide critical goods and services to coastal communities. Despite their importance, anthropogenic activities are rapidly degrading and deforesting mangroves world-wide. Madagascar contains 2% of the world’s mangroves, many of which have undergone or are starting to exhibit signs of widespread degradation and deforest...
