Testing the niche‐breadth–range‐size hypothesis: habitat specialization vs. performance in Australian alpine daisies

Relatively common species within a clade are expected to perform well across a wider range of conditions than their rarer relatives, yet experimental tests of this “niche‐breadth–range‐size” hypothesis remain surprisingly scarce. Rarity may arise due to trade‐offs between specialization and performance across a wide range of environments. Here we use common garden and reciprocal transplant experiments to test the niche‐breadth–range‐size...
