Les phytopathogènes transmis par les insectes dépendent de l'abondance et du comportement de leurs vecteurs pour favoriser leur propagation. Pentalonia nigronervosa Coquerel (Hemiptera : Aphididae) est le vecteur du Banana bunchy top virus (BBTV, genre Babuvirus). La relation hôte-parasite-vecteur est encore loin d'être élucidée.

Approximately 75% of the total area of harvested rice in the world is cultivated in the South and South-East Asian countries. However, these regions are facing both over-use of N fertilizers and salt intrusion from the sea into coastal area and river deltas.

The West-African monsoon system governs in the first order the annual cycle of rainfall over the Guinea Coast.

Interactions between microbes and minerals occur in a vast array of natural and contaminated environments. In this talk, I will discuss these interactions in the context of processes such as biomineral formation, and remediation of polluted environments.

In situ field studies in thawing permafrost regions have shown that organic carbon (OC) geochemical stability and therefore its emissions resulting from decomposition depends a.o. on the variability in soil water content, which can be directly related to microtopography.

Recently, large self-supervised pre-trained models such as GPT-3 (ChatGPT), Bert (Google), InceptionV3, … have shown that they can outperform previous state-of-the-art models and transfer to different tasks and domains. In remote sensing, a large amount of unlabelled data are freely available but gathering in situ dataset is costly.
