Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

editors usually request cover art image submissions from authors or use stock imagery (journal publishers don't usually pay artists for cover art which is weird)

Tecumseh Fitch, the editor of this special issue, chose to generate AI slop instead. He should know better

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.
