Contributions of climate, leaf area index and leaf physiology to variation in gross primary production of six coniferous forests across Europe: a model-based analysis by Duursma, R.A, Kolari, P, Peramaki, M, Pulkkinen, M, Makela, A, Nikinmaa, E, Hari, P, Aurela, M, Berbigier, P, Bernhofer, Ch, Grunwald, T, Loustau, D, Molder, M, Verbeeck, H, Vesala, T

“…Gross primary production (GPP) is the primary source of all carbon fluxes in the ecosystem. Understanding variation in this flux is vital to understanding…”

Bias in the mean tree model as a consequence of Jensen’s inequality by Duursma, R.A., Robinson, A.P.

“…Stand growth models keep track of only mean tree properties for projections of growth, because tree lists are not maintained. These properties are typically…”

Plasticity influencing the light compensation point offsets the specialization for light niches across shrub species in a tropical forest understorey by Sterck, Frank J., Duursma, Remko A., Pearcy, Robert W., Valladares, Fernando, Cieslak, Mikolaj, Weemstra, Monique

“…1. Shade tolerance can be defined as the light level at which plants can survive and possibly grow. This light level is referred to as the whole-plant light…”

Summary models for light interception and light-use efficiency of non-homogeneous canopies by Duursma, R.A, Mäkelä, A

“…The application of detailed models of canopy photosynthesis rely on the estimation of attenuation of light in the canopy. This attenuation is readily estimated…”

regression-based equivalence test for model validation: shifting the burden of proof by Robinson, A.P, Duursma, R.A, Marshall, J.D

“…Model validation is often realized as a test of how well model predictions match a set of independent observations. One would think that the burden of proof…”

Predicting the decline in daily maximum transpiration rate of two pine stands during drought based on constant minimum leaf water potential and plant hydraulic conductance by Duursma, R A, Kolari, P, Perämäki, M, Nikinmaa, E, Hari, P, Delzon, S, Loustau, D, Ilvesniemi, H, Pumpanen, J, Mäkelä, A

“…The effect of drought on forest water use is often estimated with models, but comprehensive models require many parameters, and simple models may not be…”

Description and test of a simple process-based model of forest growth for mixed-species stands by Duursma, R.A., Marshall, J.D., Robinson, A.P., Pangle, R.E.

“…Process-based models of forest growth have been discussed for decades, but their utility as management tools has only recently begun to increase. Ideally this…”
