Effects of Elevated CO2 on Litter Chemistry and Subsequent Invertebrate Detritivore Feeding Responses
Figure 1
Overview of the experimental approach.
Litter was produced under ambient- and elevated-CO2 atmospheres at BangorFACE, UK. Half of the litter from each CO2 treatment was conditioned aquatically and half terrestrially. Chemical analyses of the conditioned litter were undertaken, and litter discs were presented to aquatic and terrestrial invertebrates in choice and no-choice tests. Only one tree and one invertebrate species have been shown for clarity. Not to scale.
