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...
