Aim The Qinghai–Tibet Plateau (QTP) harbours high levels of species diversity and endemism, and multiple out‐of‐QTP dispersal routes have been put forward. However, whether different dispersal directions out of the QTP resulted in contrasting evolutionary trajectories remains unknown. Here, we use the sister genera Calathodes and Trollius (Ranunculaceae) as an ideal model to investigate the out‐of‐QTP diversification patterns....

Invasive plant species present a growing ecological and economic challenge, and often adapt rapidly to their novel environments through complex demographic and evolutionary processes. Invasion genomics offers powerful tools to disentangle these processes, but most studies rely on geographically narrow sampling across native and non‐native ranges. Erigeron canadensis is a cosmopolitan weed native to North America that has succe...

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 patterns to test these two different models in Nitrariaceae, a characteristic component of the Eurasian dryland ecosystem. We also used this fa...
