Today, we are interested in biodiversity at all levels and at all scales: from the smallest bacteria or fungi to the largest animals or plants.

Why is this multiplicity, this diversity of life forms on earth essential not only at the level of the species but also, we know less, at the level of the individuals who make up these species and all the ecosystems?

Each smallest part of living things is interconnected with the others, in interdependence and in permanent evolution... Faced with the announced and already advanced decline of this essential biodiversity, it is urgent to better understand why certain species, certain groups, but also certain plant or animal individuals resist better than others.

Thanks to what dynamics do they manage to adapt to evolve?
