             abstract = "Why do forest productivity and biomass decline with elevation? To 
                         address this question, research to date generally has focused on 
                         correlative approaches describing changes in woody growth and 
                         biomass with elevation. We present a novel, mechanistic approach 
                         to this question by quantifying the autotrophic carbon budget in 
                         16 forest plots along a 3300 m elevation transect in Peru. Low 
                         growth rates at high elevations appear primarily driven by low 
                         gross primary productivity (GPP), with little shift in either 
                         carbon use efficiency (CUE) or allocation of net primary 
                         productivity (NPP) between wood, fine roots and canopy. The lack 
                         of trend in CUE implies that the proportion of photosynthate 
                         allocated to autotrophic respiration is not sensitive to 
                         temperature. Rather than a gradual linear decline in productivity, 
                         there is some limited but nonconclusive evidence of a sharp 
                         transition in NPP between submontane and montane forests, which 
                         may be caused by cloud immersion effects within the cloud forest 
                         zone. Leaf-level photosynthetic parameters do not decline with 
                         elevation, implying that nutrient limitation does not restrict 
                         photosynthesis at high elevations. Our data demonstrate the 
                         potential of whole carbon budget perspectives to provide a deeper 
                         understanding of controls on ecosystem functioning and carbon 
                         cycling.",
