The majority of northern peatlands were initiated during the Holocene. Owing to their mass imbalance, they have sequestered huge amounts carbon in terrestrial ecosystems. Although recent syntheses filled some knowledge gaps, extent and remoteness many pose challenges developing reliable regional accumulation estimates from observations. In this work, we employed an individual- patch-based dynamic global vegetation model (LPJ-GUESS) with peatland permafrost functionality quantify long-term...
Physiological processes of terrestrial plants regulate the land-atmosphere exchange carbon, water, and energy, yet few studies have explored acclimation responses mature boreal conifer trees to climate change. Here we photosynthesis, respiration, stomatal conductance elevated temperature and/or CO2 concentration ([CO2 ]) in a 3-year field experiment with Norway spruce. We found that [CO2 ] decreased photosynthetic carboxylation capacity (-23% at 25 °C) increased shoot respiration (+64% 15...
Summary The rising levels of atmospheric carbon dioxide concentration ([ CO 2 ]) and temperature have the potential to substantially affect terrestrial water energy balance by altering stomatal conductance transpiration trees. Many models assume decreases in plant use under [ ], which has been used as a plausible explanation for positive global trend river run‐off over past century. Plant is, however, also affected changes temperature, precipitation land use, there is yet no consensus about...
Abstract Peatlands store large amounts of carbon in terrestrial ecosystems and they are vulnerable to recent warming. The ongoing warming may change their sink capacity could reduce potential sequester carbon. In this study, we simulated peatland dynamics distinct future climate conditions using the peatland‐vegetation model (LPJ‐GUESS). study examined whether less pronounced further enhance buffer effects change. It also determined which trajectory balance would follow, what main drivers...
Abstract Peatlands are huge reservoirs of carbon in the terrestrial ecosystem. They both long-term sinks organic and a major natural source atmospheric methane. These carbon-rich ecosystems at risk losing their sink capacity becoming dioxide methane due to ongoing warming. In this study, we examined past future trends peatland fluxes influence on climate system. We found that peatlands > 25 °N will remain under low-warming scenario (RCP2.6) but they would shift from being not only also...
