Temperature dependence of the relationship between pCO2 and dissolved organic carbon in lakes
The relationship between the partial pressure of carbon dioxide (pCO) and dissolved organic carbon (DOC) concentration in Brazilian lakes, encompassing 225 samples across a wide latitudinal range in the tropics, was tested. Unlike the positive relationship reported for lake waters, which was largely...

| Sumario: | The relationship between the partial pressure of carbon dioxide (pCO) and dissolved organic carbon (DOC) concentration in Brazilian lakes, encompassing 225 samples across a wide latitudinal range in the tropics, was tested. Unlike the positive relationship reported for lake waters, which was largely based on temperate lakes, we found no significant relationship for low-latitude lakes (< 33°), despite very broad ranges in both pCO and DOC levels. These results suggest substantial differences in the carbon cycling of lowlatitude lakes, which must be considered when upscaling limnetic carbon cycling to global scales. |
