The major organic components and caloric contents of high arctic bryophytes
Thirty-five bryophyte species representing the major habitats of a high arctic tundra lowland (Devon Island, Canada, 75° N) have been analyzed for contents of nitrogen, carbon, ash, and ether- and alcohol-soluble fractions. Mean contents (%) for the green portion of these species are total nitrogen,...
