Effect of measurement CO2 concentration on sugar maple root re
to predicting belowground C cycling in forest ecosystems. Inhibition of respiration has been reported as a short-term response of plant tissue to elevated measurement [CO2]. We sought to determine if measurement [CO2] affected root respiration in samples from mature sugar maple (Acer saccharum Marsh.) forests and to assess possible errors associated with root respiration measurements made at [C...
متن کاملThe effects of a changing climate on root respiration of woody plants in sugar maple forests and northern peatlands
Climate change will potentially impact C cycling in terrestrial ecosystems during the next century. Plant respiration uses a significant portion of CO2 fixed during photosynthesis, and predicted warmer future temperatures could result in an exponential increase in plant respiration, increasing the amount of photosynthate returned to the atmosphere as new CO2, and decreasing the amount of C sequ...
متن کاملField measurements of root respiration indicate little to no seasonal temperature acclimation for sugar maple and red pine.
Increasing global temperatures could potentially cause large increases in root respiration and associated soil CO2 efflux. However, if root respiration acclimates to higher temperatures, increases in soil CO2 efflux from this source would be much less. Throughout the snow-free season, we measured fine root respiration in the field at ambient soil temperature in a sugar maple (Acer saccharum Mar...
متن کاملFine root morphological traits determine variation in root respiration of Quercus serrata.
Fine root respiration is a significant component of carbon cycling in forest ecosystems. Although fine roots differ functionally from coarse roots, these root types have been distinguished based on arbitrary diameter cut-offs (e.g., 2 or 5 mm). Fine root morphology is directly related to physiological function, but few attempts have been made to understand the relationships between morphology a...
متن کاملTHE EFFECTS OF AlCl3 ADDITIONS ON RHIZOSPHERE SOIL AND FINE ROOT CHEMISTRY OF SUGAR MAPLE (ACER SACCHARUM)
Increased Al mobilization and Ca and Mg leaching have been linked to nutritional imbalances in sugar maple across the northeastern US and Canada. The susceptibility of sugar maple fine roots to Al stress is poorly understood, in part because roots respond to Al stress by altering the chemistry of the rhizosphere. AlCl3 was applied to plots of sugar maple at the Hubbard Brook Experimental Forest...
