Differing growth responses to climatic variations and soil water deficits of Fagus sylvatica, Quercus petraea and Pinus sylvestris in a temperate forest
Publication issue des travaux du projet AFOCLIM
In addition to global warming, the frequency and the intensity of droughts will probably increase in central and southern Europe. Resulting climate changes and soil water deficits could alter tree growth, according to sensitivity of each species. The aim of this study was to compare the growth response of three European species (Fagus sylvatica,...
Contrasting regional discharge evolutions in the Amazon basin (1974–2004)
Publication issue des travaux du projet REGYNA
Résumé en anglais
Former hydrological studies in the Amazon Basin generally describe annual discharge variability on the main stem. However, the downstream Amazon River only represents the mean state of the Amazonian hydrological system. This study therefore uses a new data set including...
Large-scale circulation patterns and related rainfall in the Amazon Basin: a neuronal networks approach
Publication issue des travaux du projet REGYNA
Résumé en anglais
This study describes the main circulation patterns (CP) in the Amazonian Basin over the 1975-2002 period and their relationship with rainfall variability. CPs in the Amazonian Basin have been computed for each season from the ERA-40 daily 850 hPa winds...
Variabilité hydrologique et vulnérabilité des populations du Lago Janauaca (Amazonas, Brésil)
Publication issue des travaux du projet REGYNA
Étroitement liées à la pulsation saisonnière des crues de l'Amazone, les activités des petits paysans et pêcheurs des várzeas sont particulièrement sensibles aux manifestations plus extrêmes de la variabilité hydrologique. Ce travail propose d'appréhender la vulnérabilité de ces communautés...
TRY – a global database of plant traits
Publication basée sur certains travaux du projet Humboldt.
Résumé en anglais
TRY – a global database of plant traits
Plant traits - the morphological, anatomical, physiological, biochemical, and phenological characteristics of plants and their organs - determine how primary producers...
Carbon input differences as the main factor explaining the variability in soil organic C storage in no-tilled compared to inversion tilled agrosystems
Publication issue des travaux du projet CARBOSOIL
La modification des entrées de C est le principal facteur expliquant la variation du stock de C d'un agrosystème converti au non-labour
La pratique du non-labour progresse un peu partout dans le monde. Outre certains avantages économiques et...

Publication issue des travaux du projet PASTEK.
Résumé en anglais
Land use and water quality along a Mekong tributary in Nothern Lao P.D.R.
Improving access to clean water has the potential to make a major contribution toward poverty reduction in rural communities of Lao P.D.R. This study...
Nonstationary probabilistic downscaling of extreme precipitation
Publication issue des travaux du projet REGYNA
Résumé en anglais
Nonstationary probabilistic downscaling of extreme precipitation
Reanalysis data and general circulation model outputs typically provide information at a coarse spatial resolution, which cannot directly be used...
