Abstract

Widespread conversion of coastal wetlands into aquaculture ponds in the Chinese coastal region often results in degradation of the wetland ecosystems, but its effects on sediment’s potential to produce greenhouse gases remain unclear. Using field sampling, incubation experiments and molecular analys...
