One aspect of how terrestrial ecosystems will respond to rising levels of CO2in the atmosphere is potential changes in the decomposition rate of leaf litter - a central factor in plant growth. It had been thought that the decomposition rate would decline in high CO2conditions, but this long-established hypothesis was laid to rest at a meeting in September of plant physiologists, ecologists and soil scientists.
