Belowground Carbon Budget and Nutrient Uptake of Temperate Forest Species in Response to Elevated Carbon Dioxide and Temperature
… ecosystems is lost from belowground through root respiration. Maintenance respiration of attached fine roots was measured on mature loblolly pine and sweetgum (Liquidambar styraciflua ) growing in atmospheric CO2 elevated by 200 mu1 1 -1 above ambient. Fine root maintenance respiration on a …

Environmental and developmental regulation of carbon cycling in a warm-temperate forest
… on ecosystem C loss via autotrophic respiration (Ra), I measured rates of fine root respiration at the Duke Free Air CO2 Enrichment (FACE) experiment, the longest running ecosystem level CO2 experiment in a forest. Fine roots were investigated because their respiration was known to …

Characterizing the Respiration of Stems and Roots of Three Hardwood Tree Species in the Great Smoky Mountains
Carbon dioxide efflux rates (CER) of stems and roots of overstory and understory black cherry (<i>Prunus serotina</i> Ehrh., BC), red maple (<i>Acer rubrum</i> L., RM) and northern red oak (<i>Quercus rubra</i> L., RO) trees were monitored over two growing seasons at two contrasting sites in the …
