Diverging fish biodiversity trends in cold and warm rivers and streams - Nature
In the past three decades, fish abundance, richness and uniqueness have diverged across cold and warm streams, and the effects on native fish communities of stream warming and increases in introduced fishes have magnified each other.

Most bilaterians keep photoreceptor types separate.
But vertebrate eyes are a mash-up:
🪡Ciliary (rods & cones) and
💈Rhabdomeric (ganglion, amacrine, horizontal)
…all packed into a multilayered circuit.
