For decades, marine ecologists have operated on a broadly shared assumption: as you descend into the sea, species richness thins out. Light dims, temperatures fall, productivity drops, and communities are expected to become simpler. Yet a new study from the northern Red Sea, published in the journal Coral Reefs, shows that this textbook expectation holds […]
