Pegan & Winger tested whether inversions are common within populations without phenotypic polymorphisms in 28 N. American bird species, finding that many polymorphisms are present at balanced frequencies, but possibly segregating neutrally.

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!

A handful of countries hold >70% of Earth’s terrestrial biodiversity — packed with species found nowhere else. These places are evolution’s playground… and extinction’s front line.
