Paul-André Calatayud’s (DEEIT) team published an article in collaboration with scientists from ICIPE center which results open avenues on effects of climate change on insect pest populations in east Africa. This article was the subject of a short publication on INEE web site.
Speciation is a rare phenomenon. Yet in Mayotte scientists (among them Jean David, IGGIPOP) described a population of D. yacuba drosophila feeding on the fruit of the Morinda tree which is toxic to flies on the african continent. This could provides the geographic isolation and the ecological specialization that are necessary to speciation.
