Abstract excerpt

Rapid plant radiations under climatic oscillations are widely recognised, yet our understanding of how taxonomically complex, polyploid-rich lineages diversify in extreme environments remains limited. Here, we investigated non-model Eurasian bluegrasses (Poa sect. Stenopoa), a challenging group inhabiting cold deserts, alpine grasslands, and semi-arid steppes. We utilised DArTseq genotyping of 373 individuals to...
