Global Change Biogeochemistry


Welcome to Global Change Biology’s virtual special issue highlighting a selection of our recent cutting-edge publications on the effect of global environmental change on biogeochemistry.

In this issue, we have placed a special emphasis on the interaction of global change, food and water. One paper assesses the impacts of global change on agroclimatic conditions (Trnka et al. 2011). Other studies consider the effects of global change on crop yield; wheat production decreases as temperature rises (Asseng et al.2011) and the CO2 fertilization effect will improve the yield of maize and soybean in dry conditions (McGrath and Lobell 2011).

Several papers explore the interaction between global change and soil organic matter (SOM). A meta-analysis of the impact of land-use change on soil organic carbon (SOC) stocks identifies which land-use change types result in the highest SOC losses and how these losses can be reversed (Don et al. 2011). A review of the response of SOM decomposition rates to increasing temperature presents a new conceptual model that explicitly identifies the processes controlling SOM availability and factors regulating SOM decomposition (Conant et al. 2011). Another paper presents coordinated approaches to quantifying long-term ecological responses to global change (Luo et al. 2011).

The breadth of this issue is diverse and explores other subjects, from the impacts of extreme climate events and disturbances on carbon dynamics (Stiehl-Braun et al. 2011, Hartmann 2001) to modeling of N2O fluxes and the coupling with CO2 and CH4 fluxes (Linquist et al. in press). We hope you will find the articles included in this special issue interesting and stimulating.
