Reconnecting the Cinchona (Rubiaceae) collections of the “Real Expedición Botánica al Virreinato del Perú” (1777-1816).
During the “Real Expedición Botánica al Virreinato del Perú”, 1777-1816, Hipólito Ruiz López (1754-1816), José Antonio Pavón Jiménez (1754-1840), Juan José Tafalla Navascués (1755-1811) and Juan Agustín Manzanilla (fl. 1793-1816) collected economically important specimens of anti-malarial cinchona bark (Cinchona spp.). In the 230 years since, these specimens have been dispersed...Walker, Kim ; García Guillén, Esther ; Allasi Canales, Nataly ; Medina, Leopoldo ; Driver, Felix …

The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation.
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ from each other and from the species tree. The effect of these topological incongruences...Carruthers, Tom ; Sun, Miao ; Baker, William J. ; Smith, Stephen A. ; de Vos, Jurriaan M. …

Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …

Metagenomics Shines Light on the Evolution of ‘Sunscreen’ Pigment Metabolism in the Teloschistales (Lichen-Forming Ascomycota).
Fungi produce a vast number of secondary metabolites that shape their interactions with other organisms and the environment. Characterising the genes underpinning metabolite synthesis is therefore key to understanding fungal evolution and adaptation. Lichenised fungi represent almost one-third of Ascomycota diversity and boast impressive secondary metabolites repertoires. However, most lichen... -

First evidence of a monodominant (Englerodendron, Amherstieae, Detarioideae, Leguminosae) .tropical moist forest from the early Miocene (21.73 Ma) of Ethiopia
Many tropical wet forests are species-rich and have relatively even species frequency distributions. But, dominance by a single canopy species can also occur in tropical wet climates and can remain stable for centuries. These are uncommon globally, with the African wet tropics supporting more such communities than the Neotropics or... -

Diversity patterns and conservation of the Vigna spp. in Mozambique: A comprehensive study.
Mozambique supports a high diversity of native legume species, including many Crop Wild Relatives (CWRs). Among them, the still understudied genus is a particularly notable and promising donor of favorable traits for crop improvement. This study aims to provide an updated overview of CWRs diversity in Mozambique, defining a conservation...
