Wetland carbon storage is an importantand environmentally sensitive ecosystem service. Carbon burial in the floodplain lakes of the Pantanal(tropical South America) appears to have varied during the late Quaternary, but several paleolimnological studies have recorded unusually high sedimentorganic carbon content from ~7.3 to 6.0 cal kyr BPin lakes connected to the Upper Paraguay River. We conducted a multi-indicator (phytoliths, sponge spicules, and geochemistry) study of a sediment corefrom Lake Caceres (Bolivia), and found evidence for enhanced organic carbon burial during the middle Holocene that provides insights into the flooding history of the Upper Paraguay River.d13Corgand C/Ndata suggest that organic matter deposited at that timein Lake Caceres was from macrophytes. Similar datasets from three other floodplain lakes are consistent with this finding. We suggest that enhanced carbon burial occurred when lake levels declined under relatively dry climate conditions, which increased the littoral area at the expense of open waterand captured floating macrophyte islands. This studysheds new light on hydroclimate controls on carboncycling in the Pantanal wetlands, and improves interpretations of geochemical measures on bulk organic matter in floodplain lake cores. |
