Angiosperm speciation speeds up near the poles

This study shows that speciation rates decrease towards the equator, contradicting the idea that tropical regions have higher speciation rates driving the latitudinal diversity gradient.

Different macroevolutionary routes to becoming a biodiversity hotspot

This study identifies macroevolutionary routes leading to biodiversity hotspots by analyzing speciation rates, dispersal, and environmental factors across tropical and temperate realms.

Trait evolution and historical biogeography shape assemblages of annual killifish

The paper investigates how trait evolution and historical biogeography influence species assemblages in annual killifish, finding that size variation originated in one area and spread to others with varying ecological impacts.

Range size dynamics can explain why evolutionarily age and diversification rate correlate with contemporary extinction risk in plants

The paper shows that younger and faster-diversifying plant genera have higher extinction risk, and range size dynamics may explain these patterns across the Tree of Life.

Seed size and its rate of evolution correlate with species diversification across angiosperms

The paper shows that smaller-seeded plants have higher diversification rates and that seed size change rates correlate with speciation rates across angiosperms.
