The use of an ecological niche model has made it possible to characterize on the one hand the effects of climate change on the native species of the Gulf of Lio, such as displacements of favorable habitats or the reduction of the surface of the habitat. favor of native species. On the other hand, the potential displacement of the favorable habitat of some subtropical species in the Gulf of Lion could be expected. They would then become non-indigenous species (NIS)

The use of an ecological niche model has made it possible to characterize, on the one hand, the effects of climate change on the native species of the Bay of Biscay, such as displacements of favorable habitats towards higher latitudes, or, in a to a lesser extent, a decrease in the area of ​​favorable habitat for native species. On the other hand, the potential displacement of the favorable habitat of some subtropical species (currently present along the Moroccan coast) in the Bay of Biscay could be expected. They would then become non-indigenous species (NIS)
