Simulated chronic NO3- deposition reduces soil respiration in northern hardwood forests


, : Simulated chronic NO3- deposition reduces soil respiration in northern hardwood forests. Global Change Biology 10(7): 1080-1091

Chronic N additions to forest ecosystems can enhance soil N availability, potentially leading to reduced C allocation to root systems. This in turn could decrease soil CO2 efflux. We measured soil respiration during the first, fifth, sixth and eighth years of simulated atmospheric NO3- deposition (3 g N m-2 yr-1) to four sugar maple-dominated northern hardwood forests in Michigan to assess these possibilities.

The fluorescent analog of ATP 1-N6-ethenoadenosine 5'-triphosphate (epsilon-ATP) exchanges readily with nucleotides bound to G-actin. The exchange can be observed by measuring the fluorescence intensity, which increases significantly when eps...
