Eurasian drylands are both evolutionary cradles and museums of Nitrariaceae diversity
Abstract Aim Drylands cover about 41% of Earth's land surface and are home to fragile biota with high levels of endemism. Two hypothetical models, i.e., cradle and museum, have been proposed to account for present‐day species diversity in an ecoregion or biome. We investigated macroevolutionary...
