Uplift-driven diversification in the Hengduan Mountains, a temperate biodiversity hotspot

Abstract: A common hypothesis for the rich biodiversity found in mountains is uplift-driven diversification-that orogeny creates conditions favoring rapid in situ speciation of resident lineages. We tested this hypothesis in the context of the Qinghai-Tibetan Plateau (QTP) and adjoining mountain ranges, using the phylogenetic and geographic histories of multiple groups of plants to infer the tempo (rate) and mode (colonization versus in situ diversification) of biotic assembly through time and across regions. We focused… Show more

“…From the distribution map, we can see that most phylogenetic events that occurred in the late Pliocene throughout the Pleistocene are concentrated in the E. Himalaya-Hengduan Mountains and the adjacent N. Indochinese highlands (Figure 36). This area has been impacted by tectonic shifts and climate oscillations, which could have led to high speciation (Xing & Ree 2017). Taking the subspecies divergence of G. (P.) mandarinus for instance, all infraspecific divergence times estimated by the molecular dating happened between 0.8 and 2.8 Ma, which coincides with tectonic and climatic events that occurred on the region (Lü et al 2014).…”

“…The Hengduan Mts., at the southeastern margin of the QTP, are proposed to have experienced rapid uplift during the late Miocene (Clark et al., 2005; Kirby et al., 2002). By investigating the evolutionary histories of multiple plant groups, Xing and Ree (2017) detected an increase in the rate of in situ diversification in the Hengduan Mts. during the late Miocene ( c .…”

“…The latter allows for relatively fine-grained comparisons across the 2 fundamental dimensions of historical biogeography, space and time, and is key to the main results. The method resonated with me because I performed a similar analysis in a study showing evidence for uplift-driven diversification in the Hengduan Mountains of China [2]. This analysis is complemented by a variety of other comparative methods for inferring variable diversification across clades, through time, and in response to external factors.…”
