Decreased carbon limitation of litter respiration in a mortality-affected piñon-juniper woodland

Sammanfattning

Microbial respiration depends on microclimatic variables and carbon (C) substrate availability, all of which are altered when ecosystems experience major disturbance. Widespread tree mortality, currently affecting pinon-juniper ecosystems in southwestern North America, may affect C substrate availability in several ways, for example, via litterfall pulses and loss of root exudation. To determine pinon mortality effects on C and water limitation of microbial respiration, we applied field amendments (sucrose and water) to two pinon-juniper sites in central New Mexico, USA: one with a recent (
