Bottom-up or resource control is one of the most important aspects that determine the effects of climate change on soil fauna. It remains unclear whether the response of soil fauna to climate change is detritus-based or producer-based resource driven. Soil transplantation, from Heilongjiang to Jilin and Liaoning provinces, was used to simulate the effects of climate change on Collembola through different green or brown food resource treatments, which were represented by soybean cultivation (hereafter SC), land abandonment (LA), and vegetation removal (VR).
