Abstract: The early evolutionary pattern and molecular adaptation mechanism of alpine Parnassius butterflies to high altitudes in Qinghai–Tibet Plateau are poorly understood up to now, due to difficulties in sampling, limited sequence data, and time calibration issues. Here, we present large-scale transcriptomic datasets of eight representative Parnassius species to reveal the phylogenetic timescale and potential genetic basis for high-altitude adaptation with multiple analytic strategies using 476 orthologous genes.

“…One important question is how animals regulate their metabolism and maintain their effective energy in extreme environments ( O’Brien et al, 2020 ). Studies of passerine birds, lizards, and Parnassius butterflies inhabiting the three high-altitude regions of the Qinghai–Tibet Plateau found that their gene expression correlates with altitude, suggesting that high-altitude environments may drive similar expression patterns in high-altitude species ( Yang et al, 2015 ; Hao et al, 2019 ; Su et al, 2020 ).…”

“…Niche specialisation has been considered an evolutionary dead-end (Colles et al 2009, Devictor et al 2010) due to the tendency of specialists to inhabit smaller geographical ranges, which might have enhanced extinction rates. Adaptations to extreme conditions found in Palearctic mountain summits have also been detected in Parnassius butterflies (Su et al 2020), whose species diversification in mountains was likely regulated by ecological limits (Condamine 2018). On the other hand, the linear decrease of precipitation niche with increasing precipitation (Figure 3, panel C) can reflect Erebia dependence on dry grasslands or steppe like-habitats.…”

“…The extant species diversity of temperate mountains has been primarily shaped by dispersal mediated by climatic niche conservatism (Condamine et al 2018, Liu et al 2021), but also by specialisation to extreme climatic conditions (Su et al 2020), and by diversity-dependent radiation across empty niches on isolated mountain ranges (Peña et al 2015). Such ecological intra- and inter-specific interactions in diverse groups may promote diversification, phenomenon called diversity-dependent radiation (Calcagno et al 2017).…”

“…The Palearctic fauna that diversified in colder Turkmenistan and Mediterranean subregions appeared in the west of Himalaya in the Pleistocene when the mountains had already formed (at least above timberline). Species were raised to higher elevations with continued orogenic uplift and then radiated out in an eastward direction through high‐elevation passes as seen in the butterfly genus Paranassius on the Qinghai–Tibetan Plateau (Su et al, 2020). The colonization history of butterflies suggests that the dispersal mechanism is important in shaping the current assemblages of butterflies in the Himalayan landscape.…”
