Satellite observations reveal secrets of dry tropical forest greening

In dry tropical forests, vegetation takes up water at the end of the wet season and stores it during the driest season of the year. This large amount of stored water enables trees to flush new leaves about one month before the next rainy season. This surprising phenomenon has been revealed for the first time using satellite observations, mainly in the African region of Miombo (around four times the surface area of France), in a study coordinated by the University of Copenhagen and INRA in collaboration with the CEA, CNRS, CNES and Bordeaux Science Agro.

A unique database providing information to quantify the adaptive capacity of beech to climate change

Researchers at INRA and the University of Helsinki1 have worked together to release a unique database to the scientific community2. Assembling data collected under the auspices of an EU Cost Action, the database BeechCOSTe52 gathers over 860,000 measurements of phenotypic traits. These data, from more than 500,000 beech trees growing in plantations located in 38 European countries, cover the entire range of beech’s distribution. Over 15 years of work have gone into producing the database; a vital resource for analyzing and understanding the beech’s adaptive capacity to climate change and the potential effects of climate on its distribution range.
