The new system hasn't been rolled out for every Wiley journal yet, but I am not going to submit papers to any journal that uses the new system until significant changes are made. Meanwhile, if your society journal uses Wiley, I would start looking for new publishers right now.

7/9 Wheatear coloration thus illustrates that by a modular architecture phenotypes can be decoupled within the constraints of a monogenic architecture, provided enough time for recombination. In this context, hybrid zones represent important melting pots for evolutionary tinkering.
