IAI-Data-CRN_012_Austin_BIOD-NITR: Effects of autotrophic nitrification on C and N cycling in the Patagonian steppe
Entry ID: IAIDIS764

Abstract: Human activities are altering biodiversity and the N cycle globally,
affecting marine and terrestrial carbon cycling. Only a few
specialized bacteria carry out nitrification in terrestrial
ecosystems, and determine the form and mobility of inorganic N in
soils. However, the control of these bacteria on carbon cycling is
poorly understood. This study was an ecosystem experiment in the
Patagonian steppe where we inhibited autotrophic nitrification and
measured its effects on C and N cycling. These data were collected as
part of the project CRN 012 examining the effects of biodiversity on
ecosystem functioning, led by Dr. Osvaldo Sala and with the
collaboration of Rob Jackson.
