Development of optical isotope techniques over the last several years has provided
scientists a set of tools for tracing the transport and cycling of CO2 and water vapor between …

Data assimilation, or the fusion of a mathematical model with ecological data, is rapidly
expanding knowledge of ecological systems across multiple spatial and temporal scales. As …

The magnitude of fractionation during photorespiration and the effect on net photosynthetic
13C discrimination (Δ) were investigated for three Senecio species, S. squalidus, S …

In regions where there are multiple sources of methane (CH 4) in close proximity, it can be
difficult to apportion the CH 4 measured in the atmosphere to the appropriate sources. In the …

Quantifying isotopic CO2 exchange between the biosphere and atmosphere presents a
significant measurement challenge, but has the potential to provide important constraints on …

Stable isotopes are valuable tools for partitioning the components contributing to ecological
processes of interest, such as animal diets and trophic interactions, plant resource use …

Bayesian inference methods are applied within a Bayesian hierarchical modeling framework
to the problems of joint state and parameter estimation, and of state forecasting. We explore …

Measurements of the isotopic composition of the net ecosystem–atmosphere exchange of
CO 2 (NEE) have been desired as a means to probe ecosystem carbon cycling and in …

Considerable research has recently been devoted to understanding biogeochemical
processes under winter snow cover, leading to enhanced appreciation of the importance of …

Accurate partitioning of net ecosystem exchange (NEE) of CO2 to gross primary production
(GPP) and ecosystem respiration (Reco) is crucial for understanding carbon cycle dynamics …
