Phylogenetic niche conservatism and plant diversification in South American subtropical grasslands along multiple climatic dimensions

Abstract: Phylogenetic niche conservatism can be investigated at multiple scales on an explicit geographical context. Haplotype-based comparative analyses of lineages occupying the same region, and thus subjected to similar environmental factors, allow decoupling shared evolutionary and ecological patterns, as well as multiple dimensions of adaptive diversification. Here we aimed to assess the role of environmental drivers on diversification of subtropical grassland, based on haplotypic diversity of two plant genera. We… Show more

“…In consequence, basis for the comparative analysis (i.e. PCoA, clustering) was the amount of divergence alone resulting often in a dendrogram‐based presentation of the outcome in unresolved polytomies of entities (see Figure 4, Figure S3): this makes haplotypes a poor proxy for compositional comparison of species diversity, at least in hyperdiverse and ancient tropical habitats (Barros et al, 2020; Cruz‐Salazar et al, 2021; Rodríguez et al, 2015), for which shared entities are highly informative and should be considered. Haplotypes are simply products of divergence, species often carry more than a single haplotype (or can be even heteroplasmic: i.e.…”

“…Our results revealed that the P. parodii evolutionary history agrees with the proposal for ancient lineages (Avise, 2000). The ancestor of the Petunia genus has originated in the Pampa, and the Quaternary climate shifts strongly influenced its species distribution and diversification (Barros et al, 2015(Barros et al, , 2020Ramos-Fregonezi et al, 2015;Reck-Kortmann et al, 2014), with posterior migration to the north and higher elevations (Backes et al, 2019;Lorenz-Lemke et al, 2010).…”

“…Examples of PNC in particular traits abound across multiple taxa including birds (Khaliq et al, 2015; Lovette & Hochachka, 2006), mammals (Cooper et al, 2011; da Silva et al, 2020), frogs (Hu et al, 2016; Pyron et al, 2015; Vidal‐García & Keogh, 2017), insects (D'Agostino et al, 2022; Dorey et al, 2020; Morinière et al, 2016) and plants (Ackerly, 2009; Barros et al, 2020; Folk et al, 2019; Kerkhoff et al, 2014; Kolanowska et al, 2017). Current tests of niche conservatism often examine the degree to which traits follow the phylogenetic history of a given group (Cooper et al, 2010; Münkemüller et al, 2015), but usually lack a comparative framework.…”
