- Kohlenstoff (1) (remove) - Impact of extreme hydrological
conditions on belowground carbon cycling and redox dynamics in
peat soils from a northern temperate fen (2012) - Peatlands have
an important role in the global carbon cycle and constitute the
largest pool of carbon stored in terrestrial ecosystems due to
their disproportionally high areal soil carbon density. This
globally relevant carbon stock is the result of a process mostly
initiated after the last glaciation period. A key factor for
this long term carbon accumulation is the relative low
decomposition of organic matter in these predominantly water
logged ecosystems. Hydrological conditions play thus a
fundamental role in peatlands and the feedback of carbon cycling
in these ecosystems in response to climate change is under
debate. Peatlands are important CO2 sinks but also constitute
global sources of CH4. The atmospheric exchange and production
rates of these greenhouse gases are strongly influenced by the
hydrological regime. An increased frequ
