Forests for forests
Remote sensing is a powerful tool for understanding and scaling measurements of plant carbon uptake via photosynthesis, gross primary productivity (GPP), across space and time. The success of remote sensing measurements can be attributed to their ability to capture valuable information on plant structure (physical) and function (physiological), both of which impact GPP. However, no single remote sensing measure provides a universal constraint on …
The biophysical climate mitigation potential of boreal peatlands during the growing season
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the bioph…
Tree rings provide early warning signals of jack pine mortality across a moisture gradient in the southern boreal forest
Recent declines in productivity and tree survival have been widely observed in boreal forests. We used early warning signals (EWS) in tree ring data to anticipate premature mortality in jack pine ( Pinus banksiana )—an extensive and dominant species occurring across the moisture-limited southern boreal forest in North America. We sampled tree rings from 113 living and 84 dead trees in three soil moisture regimes (subxeric, submesic, subhygric) in…
Climate control of terrestrial carbon exchange across biomes and continents
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems \nis critical to predict future levels of atmospheric carbon dioxide because of the potential \naccelerating effects of positive climate–carbon cycle feedbacks. However, directly observed \nrelationships between climate and terrestrial CO2 exchange with the atmosphere across biomes \nand continents are lacking. Here we present data describing the relatio…
