A third paper comes out. I want to stress that sequencing and annnotating the complete genome of the Balearic shearwater, under the umbrella of the @catbiogenoma.bsky.social, has been key to develope this work. Showing how the efforts of the @ebpgenome.bsky.social will help biodiversity conservation
