Short summary
Peatlands are complex and widespread ecosystems that store large amounts of carbon through photosynthesis. Carbon fixation depends on solar irradiance, and the relationship between them is called the photosynthesis-irradiance or “PI” curve. We developed a simple, portable chamber to measure PI curves in peatlands, taking into account complex plant assemblages and microhabitat variability. This tool may help scientists better understand carbon dynamics in these ecosystems.
