Field measurement of net photosynthesis of mosses at Langhovde, East Antarctica
Abstract Net photosynthesis and dark respiration (CO 2 flux) of Antarctic mosses were measured at Langhovde, East Antarctica, from 9 to 17 January 1988. Moss blocks were taken from communities in the Yukidori Valley (69°14′30″S, 39°46′00″E) at Langhovde. Each block was composed of Ceratodon purpureu...
