Author-suggested reviewers: gender differences and influences on the peer review process at an ecology journal

Peer review is the primary method by which journals evaluate the quality and importance of scientific papers. To help editors find suitable reviewers, many journals allow or require authors to suggest names of preferred and nonpreferred reviewers.
