“…() included Caltha as part of a family wide chronogram, finding an Eocene to Oligocene CG age that overlaps with our estimates of Upper Eocene to Miocene. In a phylogenetic and biogeographical study of Caltha , Cheng and Xie () estimated a Paleocene to Eocene CG age for the genus, an older estimate that does not overlap with ours (Table S1.2; Figures S1.2 and S1.3); interspecific divergences in Cheng and Xie () were consistently older than in our study, likely due to fossil choice (Appendix S1.2).…”

“…The disparity in timing is likely due to taxon sampling and choice of age priors; other than the first record of tricolpate pollen~125 Ma there was little to no overlap in calibration points used in this and other studies (Appendices S1.1 and S1.2). (Table S1.2; Figures S1.2 and S1.3); interspecific divergences in Cheng and Xie (2014) were consistently older than in our study, likely due to fossil choice (Appendix S1.2).…”

Aim In order to understand how a montane polyploid species complex responded to Cenozoic mountain uplift and climate change, we reconstructed the biogeographic history of the subalpine marshmarigold polyploid complex, including Caltha biflora, Caltha chionophila and Caltha leptosepala. Phylogenies at multiple taxonomic levels were used to estimate the timing of species divergence, allopolyploid formation and migration patterns, and to identify Last Glacial Maximum (LGM) refugia and recolonization routes. Location Western North America. Methods A fossil‐calibrated chronogram was estimated for the eudicot order Ranunculales that was in turn used to set age priors on genus‐level Caltha phylogenies. Nuclear ribosomal and chloroplast DNA sequence data were collected from subalpine marshmarigolds, including 161 specimens from across the geographical range of the complex. The datasets were analysed under a strict or relaxed molecular clock and a structured coalescent model of evolution estimated under a Bayesian framework. Results Hexaploids C. biflora and Caltha chionophila diverged in the Upper Miocene to Lower Pleistocene (chloroplast and nuclear dataset estimates overlapping at the Miocene–Pliocene boundary), and upon secondary contact formed allododecaploid C. leptosepala bidirectionally and at least three times. The hexaploids persisted to the south of LGM icesheets and recolonized LGM glaciated regions in multiple waves, mainly from the C. biflora clade in the Cascades and Coast Ranges. Main conclusions This study of a widespread western North American plant lineage shows a complex response to past geological and climatic changes, with multiple refugia, allopolyploidization events, and migrations during the Pleistocene. Bidirectional allododecaploid formation has resulted in cryptic lineages, some of which (C. leptosepala in the Cascades and Coast Ranges) have been more successful at reclaiming glaciated regions than others (C. leptosepala in the Northern Rockies).

“…The same authors estimate a more recent origin (Late Miocene to Pliocene) of alpine species of the Alpinae clade, which entered the alpine habitats several times with no subsequent radiations in high-elevation environments. The southern Andean representatives of the genus Caltha (Ranunculaceae) form two independent lineages, both with Late Miocene crown node ages (Cheng and Xie, 2014). Similar ages (∼5 Ma) were proposed for southern Andean Heliotropium sect.…”

Diversification patterns in the CES clade (Brassicaceae tribes Cremolobeae, Eudemeae, Schizopetaleae) in Andean South America

Dated molecular phylogenetic trees show that the Andean uplift had a major impact on South American biodiversity. For many Andean groups, accelerated diversification (radiation) has been documented. However, not all Andean lineages appear to have diversified following the model of rapid radiation, particularly in the central and southern Andes. Here, we investigated the diversification patterns for the largest South American-endemic lineage of Brassicaceae, composed of tribes Cremolobeae, Eudemeae and Schizopetaleae (CES clade). Species of this group inhabit nearly all Andean biomes and adjacent areas including the Atacama-Sechura desert, the Chilean Matorral and the Patagonian Steppe. First, we studied diversification times and historical biogeography of the CES clade. Second, we analysed diversification rates through time, lineages and associated life forms. Results demonstrate that early diversification of the CES clade occurred in the early to mid-Miocene (c. 12-19 Mya) and involved the central Andes, the southern Andes and the Patagonian Steppe, and the Atacama-Sechura desert. The Chilean Matorral and northern Andes were colonized subsequently in the early Pliocene (4-5 Mya). Diversification of the CES clade was recovered as a gradual process without any evidence for rate shifts or rapid radiation, in contrast to many other Andean groups analysed so far. Diversification time/rates and biogeographical patterns obtained for the CES clade are discussed and compared with patterns and conclusions reported for other Andean plant lineages.
