Changes of sulfur fractions in sediment following Spartina alterniflora invasion in a seaward direction in a temperate salt marsh, China

Changes of sulfur fractions in sediment following Spartina alterniflora invasion in a seaward direction in a temperate salt marsh, China

With immense impact on coastal ecosystems' function, especially on nutrient cycle, Spartina alterniflora has become the most importantly invasive species in coastal wetland of China. However, the alternation of sulfur level and transformation between different inorganic sulfur (IS) fractions ca...
