“…Comprehensive molecular phylogenetic analyses of Cremolobeae, Eudemeae and Schizopetaleae have recently been published (Salariato et al ., , ; Toro‐Núñez et al ., ; Toro‐Núñez, Al‐Shehbaz & Mort, ) and these tribes appeared as a monophyletic group (the CES clade) in the expanded Lineage II of the family (Warwick et al ., ; Salariato et al ., , ; Toro‐Núñez et al ., ). However, detailed analyses of the historical biogeography and spatio‐temporal diversification for the three tribes individually and for the clade as a whole are still pending.…”

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.

“…The results suggest that the main morphological specialization in Menonvillea is related with the climatic niche occupied by the species. The closely related tribe Eudemeae, which includes exclusively perennial species, diversified along the Andes without colonizing the desert regions or the adjacent Chilean Matorral, and its absence could be due to insufficient adaptation to hyperarid conditions (Salariato et al 2015). On the other hand, the tribe Schizopetaleae, which includes both perennial and annual species, is distributed primarily in the Atacama Desert and Chilean Matorral, and its species are well adapted to grow under hyperarid conditions (Toro-Núñez et al 2013).…”

The study of how climatic niches change over evolutionary time has recently attracted the interest of many researchers. Different methodologies have been employed principally to analyze the temporal dynamics of the niche and specially to test for the presence of phylogenetic niche conservatism. Menonvillea, a genus of Brassicaceae including 24 species, is distributed primarily along the Andes of Argentina and Chile, with some taxa growing in southern Patagonia and others in the Atacama Desert and the Chilean Matorral. The genus is highly diversified morphologically but also presents a remarkably wide ecological range, growing from the high Andean elevations, to the dry coastal deserts in Chile, or the Patagonia Steppe in Argentina. In this study, we used molecular phylogenies together with climatic data to study climatic niche evolution in the genus. The results show that the main climatic niche shifts in Menonvillea occurred between the sections Cuneata-Scapigera and sect. Menonvillea throughout the Mid-Late Miocene, and associated with the two main geographical distribution centers of the genus: the highlands of the central-southern Andes and the Atacama Desert-Chilean Matorral, respectively. Climatic niches in these lineages were mainly differentiated by the aridity and potential evapotranspiration, the minimum temperatures of the coldest month, and the temperature annual range and seasonality. Niche evolution in Menonvillea deviated from a Brownian motion process, with most of the climatic dimension best-fitting to an OrnsteinUhlenbeck model of multiple adaptive peaks. Our results also indicated that higher aridity levels and lower annual temperature ranges were associated with the evolution of the annual habit, as exemplified by the distribution of sect. Menonvillea. Finally, the results suggested that climatic niche evolution in Menonvillea exhibited some degree of phylogenetic niche conservatism, fundamentally within the two main lineages (sect. Menonvillea and sects. Cuneata-Scapigera).
