Ecological diversity, drift and competition

The high species diversity of many ecosystems is difficult to explain from a theoretical point of view. Among possible mechanisms, the Janzen-Connell hypothesis offers an intuitive and yet complex interaction between pests and early life stages of plants which explain the maintenance of diversity in such ecosystems. Most experimental and simulations works seem to validate this hypothesis. In this video, Samuel Charberet explains the hypothesis and mentions a recent work from Levi et al. which explored the dynamics of large ecosystems using numerical simulations. Watch Samuel's video to learn more.

Samuel Charberet is a student in the Cell Physics Master at the University of Strasbourg, France.
