Our aim was to understand the environmental conditions of the emergence and radiation of early angiosperms. Such a question has long remained controversial because various approaches applied in the past have drawn conflicting images of early angiosperm ecology. We provided a new perspective on the question by using support vector machines to model ...
Le réseau de mesure de l'OSR a été construit dans une optique de mesure des flux de contaminants d'une part, et des concentrations d'autre part. Ces deux aspects ont été largement approfondis et développés au cours de l'OSR 4, avec l'ajout d'une grande variété de contaminants et l'instrumentation de nouvelles stations, notamment dans la partie sud ...
In 2017, a total of 12 French vessels operated in the eastern Atlantic Ocean with 1 Bait Boat, 10 Purse Seiner and 1 supply vessel deploying FAD and managing a part of the FAD stock in the water. The total capacity weighted by the months of activity for each vessel is 9 907 t. The total nominal effort in 2017 was of 2794 fishing days and 2335 sets....
Soil typologies are characterized by different distribution and circulation of water, associated with specific water chemical properties, and thus potentially affects the distribution and density of malaria vectors in the Amazon. Based on a conceptual model of tropical soil evolution and distribution, the curvature of watershed slopes is a key indi...
Assessment of soil organic carbon stocks (SOCs) is highly relevant considering that SOCs is the central driver in climate change mitigation and soil fertility. In Madagascar, a first attempt at mapping SOCs on a national scale was undertaken in 2009 with previous soil data. Advanced research on soil carbon mapping on a global scale is required to e...
