Abstract

Climate: no short sharp shock Experimenters looking at the effects of a future increase in atmospheric CO2 will often expose a modern ecosystem to a high CO2 level, then see what happens. New work suggests that their results might be misleading. In a long-term (6-year) study of mycorrhizal soil fungi, an abrupt increase in CO2 had a much greater effect on biodiversity and structure in the fungal community than a gradual increase over 21 generations. It remains to be seen if a similar discrepancy occurs in field experiments, where more complex inter-species relationships apply, but it seems that caution should be exercised in interpreting the effects of changes that are more abrupt than occur naturally.
