We know that marine fishes 🐠 have an inverse gradient of speciation compared to that of spp richness, with higher speciation at higher latitudes. But, what about freshwater 🐟?

Why are some species widespread while others are found only in small, isolated areas? A study in Nature Communications shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently. #evosky 🧪
