Perturbation and Species Diversity

I discovered an interesting article that was recently published in the Journal of Ecology. The authors’ research highlights the importance of species diversity on ecosystem perturbation. Focusing on the insurance hypothesis, they demonstrated that species diversity was correlated with the recovery of a grassland ecosystem after drought. However, they were not able to find a direct correlation with species diversity and resistance to drought.
