AB Diversity of plants and animals influence soil carbon through their contributionsto soil organic matter (SOM). However, we do not know whether mammal andtree communities affect SOM composition in the same manner. This question isrelevant because not all forms of carbon are equally resistant to mineralizationby microbes and thus, relevant to carbon storage. We analyzed the elementaland molecular composition of 401 soil samples, with relation to the species richnessof 83 mammal and tree communities at a landscape scale across 4.8 millionhectares in the northern Amazon. We found opposite effects of mammal andtree richness over SOM composition. Mammal diversity is related to SOM richin nitrogen, sulfur and iron whereas tree diversity is related to SOM rich inaliphatic and carbonyl compounds. These results help us to better understandthe role of biodiversity in the carbon cycle and its implications for climate changemitigation.
