Resumo
The latitudinal diversity gradient (LDG) is one of the most widely studied
patterns in ecology, yet no consensus has been reached about its underlying
causes. We argue that the reasons for this are the verbal nature of existing
hypotheses, the failure to mechanistically link interacting ecological and evolutionary processes to the LDG, and the fact that empirical patterns are often
consistent with multiple explanations. To address this issue, we synthesize
current LDG hypotheses, uncovering their eco-evolutionary mechanisms, hidden assumptions, and commonalities. Furthermore, we propose mechanistic
eco-evolutionary modeling and an inferential approach that makes use of
geographic, phylogenetic, and trait-based patterns to assess the relative
importance of different processes for generating the LDG.
