Nested singletons in molecular trees: Utility of adding morphological and geographical data from digitized herbarium specimens to test taxon concepts at species level in the case of Casearia (Salicaceae)

open access: yesEcology and Evolution, Volume 13, Issue 1, January 2023., 2023
Using the genus Casearia, we assessed the taxonomical status of nested singletons: individual specimens corresponding to accepted species but in molecular trees appearing nested within clades of closely related species. Abstract Using the genus Casearia, we assessed the status of nested singletons: individual specimens corresponding to accepted species

Comparative wood anatomy and origin of woodiness in subfamilies Secamonoideae and Asclepiadoideae (Apocynaceae)

open access: yesTAXON, Volume 71, Issue 6, Page 1230-1250, December 2022., 2022
Abstract The Apocynaceae subfamilies Secamonoideae and Asclepiadoideae have undergone several transitions during their evolution with regard to growth form and degree of woodiness. In this study, we present a wood anatomical overview of both subfamilies that complements previous work on the remaining Apocynaceae.

Character evolution and biogeography of Casearia (Salicaceae): Evidence for the South American origin of a pantropical genus and for multiple migrations to the Caribbean islands

open access: yesTAXON, Volume 71, Issue 2, Page 321-347, April 2022., 2022
Abstract Casearia (Salicaceae) is a pantropical genus of circa 200 species, around half of which dwell in the Neotropics. Despite the availability of phylogenetic studies that suggest that Casearia sensu Sleumer is not monophyletic, a strong phylogenetic framework was still lacking for this genus.

Phylogenomics of the tropical plant family Ochnaceae using targeted enrichment of nuclear genes and 250+ taxa

open access: yesTAXON, Volume 70, Issue 1, Page 48-71, February 2021., 2021
Abstract Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens.

Tropical Refuges with Exceptionally High Phylogenetic Diversity Reveal Contrasting Phylogenetic Structures

open access: yesInternational Journal of Biodiversity, Volume 2015, Issue 1, 2015., 2015
Loss of phylogenetic diversity (PD) has gained increasing attention in conservation biology. However, PD is not equally distributed in a phylogeny and can be better assessed when species relatedness (phylogenetic structure: PS) is also considered. Here, we investigate PD and PS in two refuges of biodiversity in northeastern Brazil: the Bahia Costal ...
