46 p, 3.4 MB Vertical variation in photosynthetic parameters in two different tropical forest ecosystems / Knaepen, Wouter ; Janssens, Ivan A. (Universiteit Antwerpen) ; Verryckt, Lore (Universiteit Antwerpen) ; Universiteit Antwerpen Plant and Vegetation Ecology
Forests contribute to the carbon balance as the largest vegetative sink for atmospheric carbon (CO2). Anthropogenic emissions are counteracted by carbon sequestration in trees, but nutrients could be limiting photosynthesis and the effect could possibly be not as large as believed. [...]

12 p, 3.3 MB Pathways for balancing CO2 emissions and sinks / Walsh, Brian (International Institute for Applied Systems Analysis (Àustria)) ; Ciais, Philippe (Laboratoire des Sciences du Climat et de L'Environnement (França)) ; Janssens, Ivan A. (University of Antwerp (Bèligica)) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
In December 2015 in Paris, leaders committed to achieve global, net decarbonization of human activities before 2100. This achievement would halt and even reverse anthropogenic climate change through the net removal of carbon from the atmosphere. [...]

This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland site that has been warm for at least 50 years (GO), and another comparable grassland site (GN) and a Sitka spruce plantation (FN) site that have both been warmed since an earthquake took place in 2008.

Three times greater weight of daytime than of night-time temperature on leaf unfolding phenology in temperate trees / Fu, Yongshuo H. (Sino-French Institute for Earth System Science) ; Liu, Yongjie (Universiteit Antwerpen. Departement Biologie) ; De Boeck, Hans J. (Universiteit Antwerpen.

(Universiteit Antwerpen. Departement Biologie)
The phenology of spring leaf unfolding plays a key role in the structure and functioning of ecosystems. The classical concept of heat requirement (growing degree days) for leaf unfolding was developed hundreds of years ago, but this model does not include the recently reported greater importance of daytime than night-time temperature.

15 p, 2.3 MB Towards a representation of priming on soil carbon decomposition in the global land biosphere model ORCHIDEE (version 1.9.5.2) / Guenet, Bertrand (Laboratoire des Sciences du Climat et de l’Environnement) ; Esteban Moyano, Fernando (Georg-August University of Göttingen.

(University of Antwerp. Research Group of Plant and Vegetation Ecology)
Priming of soil carbon decomposition encompasses different processes through which the decomposition of native (already present) soil organic matter is amplified through the addition of new organic matter, with new inputs typically being more labile than the native soil organic matter. [...]

33 p, 2.1 MB Priming of soil organic matter decomposition scales linearly with microbial biomass response to litter input in steppe vegetation / Xiao, Chunwang (Chinese Academy of Sciences. State Key Laboratory of Vegetation and Environmental Change) ; Guenet, Bertrand (University of Antwerp. Research Group of Plant and Vegetation Ecology) ; Zhou, Yong (Chinese Academy of Sciences. State Key Laboratory of Vegetation and Environmental Change) ; Su, Jiaqi (Chinese Academy of Sciences. State Key Laboratory of Vegetation and Environmental Change) ; Janssens, Ivan A. (University of Antwerp. Research Group of Plant and Vegetation Ecology)
Fresh plant litter inputs accelerate soil organic matter (SOM) decomposition through a ubiquitous mechanism called priming. Insufficient priming has been suggested as a stabilization mechanism of SOM at depth, as well as the long-term persistence of some highly degradable organic compounds in soils. [...]

Well-defined productivity–precipitation relationships of ecosystems are needed as benchmarks for the validation of land models used for future projections. The productivity–precipitation relationship may be studied in two ways: the spatial approach relates differences in productivity to those in precipitation among sites along a precipitation gradient (the spatial fit, with a steeper slope); the temporal approach relates interannual productivity changes to variation in precipitation within sites (the temporal fits, with flatter slopes).

Aim Plant elemental composition and stoichiometry is crucial for plant structure and function. We studied to what extent plant stoichiometry might be caused by environmental drivers and competition from coexisting species. [...]
