Heimann, ed., The Global Carbon Cycle
(Berlin: Springer-Verlag, 1994).
This book contains the proceedings of a NATO
Advanced Research Workshop held within the activities
of the NATO Special Program on Global Environmental
Change, which started in 1991 under the auspices
of the NATO Science Committee. In his article
"Biome Modeling and the Carbon Cycle,"
Colin Prentice defined "biomes" as
structurally and functionally distinct ecosystem
complexes. There are 15-20 different biomes--some
easy to distinguish as tundra, hot deserts,
temperate deciduous forests, and tropical rain
forests--others are more difficult to classify.
Differences between biomes are important for
the carbon cycle because they account for much
of the spatial variation in the size of biomass
and soil carbon stores.
