Non-structural carbohydrates (NSC) in plant tissue are frequently quantified to make inferences about plant responses to environmental conditions. Laboratories publishing estimates of NSC of woody plants use many different methods to evaluate NSC. We asked whether NSC estimates in the recent literature could be quantitatively compared among studies. We also...

The exchange of carbon dioxide is a key measure of ecosystem metabolism and a critical intersection
between the terrestrial biosphere and the Earth’s climate. Despite the general agreement that
the terrestrial ecosystems in North America provide a sizeable carbon sink, the size and distribution
of the sink remain uncertain. We...

We developed a new climate-sensitive vegetation state-and-transition simulation
model (CV-STSM) to simulate future vegetation at a fine spatial grain commensurate
with the scales of human land-use decisions, and under the joint influences of changing
climate, site productivity, and disturbance. CV-STSM integrates outputs from four different
modeling systems. Successional changes in...

A new model to simulate climate-change impacts on forest
The ¹⁴CO₂ composition of plant and soil respiration can be used to determine the residence time of photosynthetically fixed carbon before it is released back to the atmosphere. To estimate the residence time of actively cycled carbon in a temperate forest, we employed two approaches for estimating the Δ¹⁴CO₂ of...

Iron (Fe) and copper (Cu) are essential cofactors for microbial metalloenzymes, but little is known about the metalloenyzme inventory of anaerobic marine microbial communities despite their importance to the nitrogen cycle. We compared dissolved O₂ , NO₃⁻, NO₂⁻, Fe and Cu concentrations with nucleic acid sequences encoding Fe and Cu-binding...
