Recovery of metabolites via subnivean photosynthesis in Arctic tundra plants: Implications for climate change
Abstract Plants have evolved numerous strategies for surviving the harsh conditions of the Arctic. One strategy for Arctic evergreen and semi‐evergreen species is to photosynthesize beneath the snow during spring. However, the prevalence of this photosynthesis and how recent photosynthates are used...

Abstract Plants have evolved numerous strategies for surviving the harsh conditions of the Arctic.

To answer this question, we delivered isotopically labeled 13CO2 to tussock tundra plants before snowmelt.
