COMPARISON OF NET PHOTOSYNTHESIS AND DARK RESPIRATION OF ANTARCTIC MOSSES MEASURED IN THE ANTARCTIC AND IN JAPAN (Eleventh Symposium on Polar Biology)
Net photosynthesis and dark respiration (CO_2 uptake) of Antarctic mosses were measured to investigate the effects of transportation in a frozen condition from the Antarctic to Japan. Moss blocks were collected from some Ceratodon purpureus communities in different habitats at the Yukidori Valley (6...

Net photosynthesis and dark respiration (CO_2 uptake) of Antarctic mosses were measured to investigate the effects of transportation in a frozen condition from the Antarctic to Japan. Moss blocks were collected from some Ceratodon purpureus communities in different habitats at the Yukidori Valley (69°14'30"S, 39°46'00"E) in Langhovde, East Antarctica, on January 16, 1988. The CO_2 uptake activities of the surface layer of the moss blocks were measured in the laboratory on the research ship SHIRASE with two infrared CO_2 gas analyzers and an assimilation chamber within a month after the collection. The relationships of net photosynthesis and dark respiration to water content, illumination intensity, and temperature were determined.
