The principles of experimental design in ecology and evolution has 20k downloads, but unfortunately I still have to reject ~20% of papers without review because they lack replication at the right level. More discussion among mentors and mentees please.

Principles of experimental design for ecology and evolution
Here I argue that we do not discuss experimental design, often until it is too late. This editorial seeks to begin a conversation about how and where to replicate appropriately.
