Surprise Result: Increasing Dispersal Increases Ecological Diversity

A study of microbes that live in the nectar of flowers has turned up an unexpected result that challenges a common assumption in ecology.

It’s been widely assumed that the more easily organisms can disperse between habitats, the more similar the mix of species in those habitats will be.
