The high levels of biodiversity supported by mountains suggest a possible link between geologic processes and biological evolution. Freshwater is not only in tectonically active settings but also quiescent montane regions such as the Appalachian Mountains. We show that erosion through different rock types drove allopatric divergence lineages Greenfin Darter (Nothonotus chlorobranchius), fish species endemic to rivers draining metamorphic rocks Tennessee River basin United States. In past, preferred N. chlorobranchius was more widespread, exposed other types, this were progressively isolated tributaries farther upstream, where remained. Our results mechanism for initiating diversification long after tectonic activity ceases.

The current status of the Sino-Himalayan region as a biodiversity hotspot, particularly for flora, has often been linked to uplift Sino-Tibetan Plateau and Himalayan Hengduan Mountains. However, relationship between topological development onset diversification is yet be confirmed. Here, we apply Bayesian phylodynamic methods large phylogeny angiosperm species from Sino-Himalayas infer changes in their rates evolution through time. We find strong evidence high Paleocene, late Miocene Pliocene, negative Quaternary driven by an increase extinction rates. Our analyses suggest that global palaeotemperatures are unlikely driving force these rate shifts. Instead, collision Indian continent with Eurasia coeval topographic change Sino-Himalayas, Grassland Expansion impact Pleistocene glaciations on this altitudinally variable may have also demonstrate influence choice times shape inferred piecewise-constant trajectories phylodynamics, advocate use prior information when making decision.

Cymbidium (Orchidaceae: Epidendroideae), with around 60 species, is widely-distributed across Southeast Asia, providing a nice system for studying the processes that underlie patterns of biodiversity in region. However, phylogenetic relationships have not been well resolved, hampering investigations species diversification and biogeographical history this genus. In study, we construct plastome phylogeny 56 four well-resolved major clades, which provides framework rate analyses. Molecular dating analyses show likely originated region spanning northern Indo-Burma to eastern Himalayas during early Miocene (∼21.10 Ma). It then rapidly diversified into clades East Asia within approximately million years middle Miocene. spp. migration adjacent regions (Borneo, Philippines, Sulawesi) primarily occurred Pliocene-Pleistocene period. Our indicate net has decreased since its origin, positively associated changes temperature monsoon intensity. Favorable hydrothermal conditions brought by intensification possibly contributed initial rapid diversification, after was reduced cooling climate The transition from epiphytic terrestrial habits may enabled adaptation cooler environments colonization niches, yet without significant effect on rates. This study new insights how activity affected dynamics plants Asia.
