Comparing traits of native and alien plants: Can we do better?

In a forum paper published this month in Functional Ecology, Philip Hulme and I discuss how to improve trait-based empirical approaches to understand the success and impact of alien plant species. Our aim was to encourage invasion ecologists to draw lessons from past mistakes and recent innovations in the field of community ecology. We highlight seven main points to keep in mind in order to avoid common pitfalls and optimize empirical comparisons of alien vs. native trait distributions.
