Climate change predictions derived from coupled carbon-climate models are highly dependent
on assumptions about feedbacks between the biosphere and atmosphere. One critical …

Soil temperature can influence the functioning of roots in many ways. If soil moisture and
nutrient availability are adequate, rates of root length extension and root mortality increase with …

There is considerable uncertainty about how rates of soil carbon (C) and nitrogen (N) cycling
will change as CO2 accumulates in the Earth's atmosphere. We summarized data from 47 …

A 2 x 2 nutrient and water factorial experiment with four replications was installed in an 8-yr-old
stand of loblolly pine (Pinus taeda L.) growing on an infertile, excessively drained sandy …

• Availability of growth limiting resources may alter root dynamics in forest ecosystems,
possibly affecting the land–atmosphere exchange of carbon. This was evaluated for a …

During 2005–2007, we used the eddy covariance and associated hydrometric methods to
construct energy and water budgets along a chronosequence of loblolly pine (Pinus taeda) …

The Eucalyptus genus yields high rates of productivity and can be grown across a wide range
of site types and climates for products such as pulp, fuelwood, or construction lumber. In …

• Concentrations of atmospheric CO 2 and tropospheric ozone (O 3 ) are rising concurrently
in the atmosphere, with potentially antagonistic effects on forest net primary production (NPP…

• Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs
in many ecosystems, potentially influencing both water use and carbon assimilation. • By …

• The Rhinelander free‐air CO 2 enrichment (FACE) experiment is designed to understand
ecosystem response to elevated atmospheric carbon dioxide (+CO 2 ) and elevated …
