Aim. Dynamic global vegetation models (DGVMs) use a discretization of forest vegetation based on plant functional types (PFTs). The physiological and ecological parameters used to model a given PFT are usually fixed, being defined from point-based observations, while model applications are often grid-based. [...]

10 p, 1.2 MB Spatial variance of spring phenology in temperate deciduous forests is constrained by biogeographical conditions of temperature, light and aridity / Peaucelle, Marc (Universiteit Gent.

Leaf unfolding in temperate forests is driven by spring temperature, but little is known about the spatial variance of that temperature dependency. Here we use in situ leaf unfolding observations for eight deciduous tree species to show that the two factors that control chilling (number of cold days) and heat requirement (growing degree days at leaf unfolding, GDDreq) only explain 30% of the spatial variance of leaf unfolding. [...]

Every living creature on Earth is made of atoms of the various bioelements that are harnessed in the construction of molecules, tissues, organisms, and communities, as we know them. Organisms need these bioelements in specific quantities and proportions to survive and grow. [...]

Most studies of the northern hemisphere carbon cycle based on atmospheric CO2 concentration have focused on spring and autumn, but the climate change impact on summer carbon cycle remains unclear. Here we used atmospheric CO2 record from Point Barrow (Alaska) to show that summer CO2 drawdown between July and August, a proxy of summer carbon uptake, is significantly negatively correlated with terrestrial temperature north of 50°N interannually during 1979-2012.

Representing explicit budburst and senescence processes for evergreen conifers in global models / Peaucelle, Marc (Laboratoire des Sciences du Climat et de l'Environnement) ; Ciais, Philippe (Laboratoire des Sciences du Climat et de l'Environnement) ; Maignant, Fabienne (Laboratoire des Sciences du Climat et de l'Environnement) ; Nicolas, Manuel (France.

Département Recherche Développement et Innovation) ; Viovy, Nicolas (Laboratoire des Sciences du Climat et de L'Environnement)
Global ecosystem models lack an explicit representation of budburst and senescence for evergreen conifers despite their primordial role in the carbon cycle. In this study we evaluated eight different budburst models, combining forcing, chilling and photoperiod, for their ability to describe spring budburst, and one model of needle senescence for temperate evergreen coniferous forests.
