Tropical soils could dominate the short-term carbon cycle feedbacks to increased global temperatures

摘要: Results of a simple model the effects temperature on net ecosystem production call into question argument that large stocks soil carbon and greater projected warming in boreal tu ndra regions world will lead to rapid efflux from these biomes atmosphere. We show low rates turnover relatively response primary changes may storage over some limited range warming. In contrast, high respiration found tropical ecosystems are highly sensitive small temperature, so despite less pronounced expected equatorial regions, soils likely release amounts for high-latitude parameter values used, while tropics appears robust.
