Phylogeography of the Dendrocolaptes picumnus (Aves: Dendrocolaptidae) species complex: new insights on the diversification of a trans‐American lineage

“…We sequenced 87 specimens and used previously available sequences from 19 specimens (Santana et al 2021a) distributed as follows across all but four taxa of the D. picumnus species complex regarded as valid (Gill et al 2020): D. p. costaricensis (n = 1), D. p. olivaceus (n = 6), D. p. pallescens (n = 12), D. p. picumnus (n = 15), D. p. transfasciatus (n = 11), D. p. validus (n = 25), D. hoffmannsi (n = 16), D. platyrostris intermedius (n = 12), and D. p. platyrostris (n = 11) (Fig. 1; Supporting information).…”

“…Sequences were concatenated in Sequence Matrix 1.7.8 (Vaidya et al 2011) and the best partition scheme Figure 1. Geographic distribution of taxa in the Dendrocolaptes picumnus species complex (sensu Santana et al 2021a) and genetic sampling employed in this study. Different colors show the ranges of each taxon as described in Dickinson and Christidis (2014), Gill et al (2020) and Marantz et al 2020Marantz et al , 2020.…”

“…However, the most complete molecular phylogeny available to date for the genus Dendrocolaptes in general and which included 19 specimens belonging to all species and most subspecies in the D. picumnus species complex, recovered both D. hoffmannsi and D. platyrostris as monophyletic, but showed D. picumnus as a paraphyletic species, with D. hoffmannsi nested in it (Santana et al 2021a). This same study also showed that several independent evolutionary lineages in the polytypic D. picumnus (some of them corresponding to formally recognized subspecies) might represent independent species; however, conclusions were weakened due to a sampling restricted to a maximum of three specimens per taxon (Santana et al 2021a). To further evaluate phylogenetic relationships, species limits and the diversification history of the entire D. picumnus species complex, with a greater sampling regime, we herein analyze sequences of mitochondrial and nuclear genes from 106 specimens belonging to all but four taxa grouped in the complex.…”

A general scenario to evaluate evolution of grassland birds in the Neotropics

“…2020, Santana et al . 2020), limiting our understanding of the potential historical scenarios that characterize these ecosystems as well as the potential processes shaping genetic diversity across taxa. Therefore, new information about the phylogeographical history of taxa that specialize in this type of habitat is crucial to understand the historical and geological processes that have shaped the biodiversity of this biome (Antonelli et al .…”

“…Phylogeographical studies on organisms inhabiting grasslands in the Neotropics are still in their infancy (Bates et al 2003, Masello et al 2011, Campagna et al 2012a, 2012b, Lopes et al 2018, Moura et al 2018, Norambuena et al 2018, Lima-Rezende et al 2019, Corbett et al 2020, Rocha et al 2020, Santana et al 2020, limiting our understanding of the potential historical scenarios that characterize these ecosystems as well as the potential processes shaping genetic diversity across taxa. Therefore, new information about the phylogeographical history of taxa that specialize in this type of habitat is crucial to understand the historical and geological processes that have shaped the biodiversity of this biome (Antonelli et al 2010, Brumfield 2012.…”
