Mangroves dwell at the land-ocean interface and are thus encroached upon by competing land use at the coastal zone. They are also subject to impacts from catchments developments. As a result, mangroves worldwide are having their extension changed (Spalding et al, 1997). Worldwide it is well accepted that mangrove extension is decreasing mostly due to conversion to other uses, in particular aqua...

Mangroves are ecosystems with enormous ecological importance, supporting both terrestrial and marine food webs. They provide ecosystem services (e.g. food, medicines, fuel, constructing material) to communities near and far. Despite their importance, mangrove areas are facing numerous threats. Based on neo-Malthusian narratives, population growth is an alleged main cause of mangrove degradation...

BACKGROUND Worldwide there is growing research interest in the ethnobiology of mangrove forests. Notwithstanding that, little information has been published about ethnobiology of mangrove forests in Cameroon. The aims of this study were a) to analyze the harvesting methods and the local selling of mangrove wood products by loggers in the vicinity of Wouri estuary and b) to investigate the patte...

In recent decades, the mangrove area in China has changed dramatically, and governments have established multiple protected areas at various levels. However, we know little about effectiveness of conservation on mangroves a national scale. this study, constructed an evaluation index system for landscape health proposed composite (LHCI) to characterize status mangroves. Based distribution datase...

Mangrove restoration projects are often evaluated based on the increase in mangrove forest (MF) area, but reliability of this indicator as a measure successful is questionable. Considering both numerical and quality dimensions, study assessed efforts Leizhou Peninsula Beibu Gulf (LP-BG) China. The hypothesis was that due to limited social capital investment restoration, there exist hierarchical...

Mangroves can capture and store organic carbon and their protection and therefore their restoration is a component of climate change mitigation. However, there are few empirical measurements of long-term carbon storage in mangroves or of how storage varies across environmental gradients. The context dependency of this process combined with geographically limited field sampling has made it diffi...

Royal mangrove wetland, Jamaica.” Journal of Coastal Research 14(3): 951-959. Studies on the historical development of mangrove wetlands are rare in contrast to the vast array of information on the geological development of these systems. Historical development of the Port Royal mangal was investigated so as improve understanding of recent changes occurring in relation to the increasing threat ...

The origin of carbon substrates used by in situ sedimentary bacterial communities was investigated in an intertidal mangrove ecosystem and in adjacent seagrass beds in Gazi bay (Kenya) by δ13C analysis of bacteria-specific PLFA (phospholipid fatty acids) and bulk organic carbon. Export of mangrove-derived organic matter to the adjacent seagrasscovered bay was evident from sedimentary total orga...

Lin, G., Banks, T. and Sternberg, LO., 1991. Variation in 5~3C values of the seagrass Thalassia testudinum and its relations to mangrove carbon. Aquat. Bot., 40: 333-341. Carbon isotope ratios (~3C/t2C) were measured for the leaves of the seagrass Thalassia testudinum Banks ex K/Snig and carbonates of shells collected at the seagrass beds from seven sites along the coast of southern Florida, U....
