WHEN BUDGETS DON'T BALANCE: INDICATORS OF SHIFTING CARBON BALANCES AND LESSONS TO LEARN FROM THEM
Carbon mass balances represent a useful (if bulky) tool in identifying the flow and fate of carbon in aquatic ecosystems, yet our best efforts to quantify total annual inputs and outputs don’t always work out. A fundamental assumption for any carbon mass balance is that the system is at equilibrium: that annual terrestrial and atmospheric carbon inputs must be equivalent to annual outputs (through carbon export, burial, or emissions). However, internal carbon subsidies (such as large pools of dissolved organic carbon) or changes in the size of the biotic community in a lake can throw off this assumption, and are important to consider especially in face of accelerating climate change. I present data supporting the occurrence of such carbon budget shifts, and discuss their potential implications for understanding lake community shifts.
