Plant diversity and ecology on the Qinghai–Tibet Plateau.

As the well known biodiversity hotspot of the alpine plants in the world (Sun et al., 2017), many studies have been conducted on evolutionary origin and ecological adaptation of those species occurring in the QTP (e.g., Wen et al., 2014, 2019; Zhang et al., 2019). The Qinghai-Tibet Plateau (QTP) comprises a platform (sometimes called the Qinghai-Tibet Plateau I sensu stricto i ), the Himalayas, and Hengduan Mountains (Liang et al., 2018; Mao et al., 2021). Tong et al. (2021) reviewed the reproductive strategies of animal-pollinated alpine plants on the QTP, involving pollination system, pollen limitation, self-pollination, and sexual system. Paleobotany for Ancient Flora of the QTP and Related Paleo-Altitude Paleontology provides direct evidence for ancient flora of the QTP and further evolution in both floral composition and altitude change with time.
