🚨 Super exited to see our paper on the inheritance and genetic basis of guppy color variation come out in @natecoevo.nature.com rdcu.be/eugWV
Guppy males have enormous variation in color patterns, with many combinations of ornamental spots and stripes. But where does all this variation come from?

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!

So Google Scholar now links to an.. 18+ website to read my latest @natecoevo.nature.com paper. 🤔
It does include some guppy mating behavior.. but this seems like an overreaction.

NEW: Common Crawl, the massive archiver of the web, has gotten cozy with AI companies and is providing paywalled articles for training data. They’re also lying to publishers who have asked for material to be removed. “The robots are people too,” CC’s exec director told us when we asked about this.

What’s the point of including such an unspecified declaration? It seems equivalent to declaring “we have competing interests” but not declaring what they are.
