  author={Ana M Morales-Williams and Alan D. Wanamaker and Clayton J. Williams and John A. Downing},
Lakes process a disproportionately large fraction of carbon relative to their size and spatial extent, representing an important component of the global carbon cycle. Alterations of ecosystem function via eutrophication change the balance of greenhouse gas flux in these systems. Without eutrophication, lakes are net sources of CO 2 to the atmosphere, but in eutrophic lakes this function may be amplified or reversed due to cycling of abundant autochthonous carbon. Using a combination of high… 
Eutrophication and temperature drive large variability in carbon dioxide from China's Lake Taihu
Eutrophication and warming are changing the functioning of lake ecosystems, and their impacts on lake carbon dioxide (CO2) variability have received increasing attention. However, how eutrophication
Notable changes of carbon dioxide in a eutrophic lake caused by water diversion

How humans alter dissolved organic matter composition in freshwater: relevance for the Earth’s biogeochemistry
Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems, but historical reliance on DOM quantity rather than indicators of DOM composition has led to an incomplete


Carbon dioxide concentrations in eutrophic lakes: undersaturation implies atmospheric uptake
Abstract Understanding concentrations and contributions of carbon dioxide (CO2) in aquatic ecosystems is an important part of a comprehensive global carbon budget. Current dogma suggests that world
Cyanobacterial carbon concentrating mechanisms facilitate sustained CO 2 depletion in eutrophic lakes
Abstract. Phytoplankton blooms are increasing in frequency, intensity, and duration in aquatic ecosystems worldwide. In many eutrophic lakes, these high levels of primary productivity correspond to
Seasonal patterns in carbon dioxide in 15 mid-continent (USA) reservoirs
Abstract Evidence suggests that lakes are important sites for atmospheric CO2 exchange and so play a substantial role in the global carbon budget. Previous research has 2 weaknesses: (1) most data
Eutrophication reverses whole-lake carbon budgets
Abstract Lakes play a large role in global atmospheric and landscape carbon (C) processes, but their role may change as they become polluted with nutrients. Geographic regions rich in surface waters
Hydrologic support of carbon dioxide flux revealed by whole-lake carbon budgets
[1] Freshwater lakes are an important component of the global carbon cycle through both organic carbon (OC) sequestration and carbon dioxide (CO2) emission. Most lakes have a net annual loss of CO2
Seasonal Dynamics of CO2 Flux Across the Surface of Shallow Temperate Lakes
We used data collected from 1989 to 2009 from 151 shallow (mean depth < 3 m) temperate lakes in Denmark to explore the influence of lake trophic status, surface area and catchment size on the
Role of a productive lake in carbon sequestration within a calcareous catchment.
Impacts of Eutrophication on Carbon Burial in Freshwater Lakes in an Intensively Agricultural Landscape
The influence of inland water bodies on the global carbon cycle and the great potential for long-term carbon burial in them is an important component of global limnology. We used paleolimnological
Climate‐dependent CO2 emissions from lakes
Inland waters, just as the world's oceans, play an important role in the global carbon cycle. While lakes and reservoirs typically emit CO2, they also bury carbon in their sediment. The net CO2
Net heterotrophy and CO2 evasion from a productive calcareous reservoir: Adding complexity to the metabolism‐CO2 evasion issue
[1] The role of lacustrine systems in the global carbon cycle is a major topic in freshwater research. Most lakes release inorganic carbon to the atmosphere owing to the imbalance of net metabolism
