As warming pushes species’ ranges into new overlap zones, previously isolated animals are starting to interbreed. Texas biologists documented a wild blue jay–green jay hybrid linked to both species expanding northward, signaling that climate change can assemble novel ecological communities.
— It shows climate change is not just about temperatures but about reconfiguring biodiversity, complicating species protection, invasive‑species policy, and how we measure ecological loss.
