Description
Thayamkottu and five colleagues model carbon fluxes in an Alaskan rich fen from twenty fourteen to twenty twenty in twenty twenty-four. Boreal peatlands store vast soil carbon because growth outpaces decay. Warming now threatens that balance. The team asked what drives year to year change in carbon dioxide fluxes at the site.
They used an ecosystem model tuned by Bayesian fusion with flux, satellite, and field data. Leaf area rose over the study years in a clear greening trend. The authors attribute that trend to carbon dioxide fertilisation of plant growth. Gross plant production rose by about seventy-five grams of carbon per square metre yearly. Breathing of soil microbes stayed roughly constant. The ecosystem shifted more carbon into foliage than into stems or roots.
