On carbon sequestration in desert ecosystems
Global Change Biology
Recent reports of net ecosysytem production >100 gCm−2 yr−1 in deserts are incompatible with existing measurements of net primary production and carbon pools in deserts. The comparisions suggest that gas exchange measurements should be used with caution and better validation if they are expected to indicate the magnitude of carbon sink in these ecosysytems.
