Data gaps and biases are two important issues that affect the quality of biodiversity information and downstream results. Understanding how best to fill existing gaps and account for biases is necessary to improve our current information most effectively. Two current main approaches for obtaining and improving data include (1) curation of biologica...

Using the genus Casearia, we assessed the status of nested singletons: individual specimens corresponding to accepted species but in molecular trees appearing nested within clades of closely related species. Normally, such cases would be left undecided, while on the other hand, timely taxonomic decisions are required. We argue that morphological, c...

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. We tested the monophyly of Casearia and examined the relatio...

Anexo 2. Diversidad florística. Se presenta una lista de las plantas vasculares presentes en Bogotá D.C. (Anexo 2), con 3017 especies y 27 híbridos, para un total de 3044 taxones organizados por familia, con los siguientes campos: endemismo para Colombia, estado de amenaza de extinción, origen (nativa/ no nativa), y un ejemplar representativo del D...

Bogotá D.C. is a highly diverse territory in the tropical Andes, with more than 70% rural area, where high mountain ecosystems predominate. Despite its richness and floristic diversity, an inventory of the species of the vascular flora of the District has not been gathered until now. For this reason, the first inventory of the native and non-native...

Bogotá, Distrito Capital, es un territorio altamente diverso de los Andes tropicales, con más de 70 % de área rural, en donde predominan ecosistemas de alta montaña. A pesar de su riqueza y diversidad florística, hasta la fecha no se ha realizado un inventario de las especies que componen la flora del Distrito. Por esta razón, se presenta el primer...

A través de los años el Jardín Botánico de Bogotá ha realizado numerosos esfuerzos para la publicación de guías de campo tratando algunos grupos de plantas, colecciones o áreas específicas de las colecciones vivas del Jardín. Entre estas, solo para mencionar algunas, se elaboró la Guía ilustrativa de las colecciones especializadas para la conservac...

We present a first study of the diversity and community composition of lichens in seasonally dry tropical forest (DTF) remnants in the Atlántico department, Colombia. Lichens were sampled in two of the three protected areas of the department: Distrito de Manejo Integrado (DMI) Luriza and Reserva Forestal Protectora (RFP) El Palomar. The inventory r...

Although ethnobotanical knowledge is considered potentially valuable information for several human disciplines, it is currently declining due to a decrease in the transmission of cultural knowledge and the depletion of natural resources. Consequently, focused efforts are required to compile such information and ultimately facilitate its diffusion....

The origin of Neotropical species diversity is strongly associated with the geological history of South America. Since the Miocene, a number of species radiations across different Neotropical lineages coincided with the rise of the Andes and the formation of the Isthmus of Panama. The species-rich genus Philodendron Schott (Araceae) is widely distr...

The vascular plants of the Americas Botanical exploration in the Americas has a history that stretches back for half a millennium, with knowledge assembled in diverse regional floras and lists. Ulloa Ulloa et al. present a comprehensive and integrated compilation of all known native New World vascular plant species (see the Perspective by Givnish)....

Significance Large floristic datasets that purportedly represent the diversity and composition of the Amazon tree flora are being widely used to draw conclusions about the patterns and evolution of Amazon plant diversity, but these datasets are fundamentally flawed in both their methodology and the resulting content. We have assembled a comprehensi...

Following a large-scale phylogenetic study of the lichenized genus Cora (Basidiomycota: Agaricales: Hygrophoraceae), we formally describe 70 new species, honouring the seventieth birthday of David Leslie Hawksworth, one of the preeminent figures in mycology and lichenology in the past 50 years. Based on an updated phylogeny using the ITS fungal bar...

Introduction: The use of greater amounts of protein and energy during the first week of life is associated with hypophosphataemia in extreme preterm babies. The lowest phosphorus levels are described in intrauterine growth restricted (IUGR) babies. Objectives: To describe biochemistry levels in cord blood plasma in extreme premature, adequate an...

Sixty-seven new combinations, replacement names and changes of status are validated for Colombian plants and lichens in the families Parmeliaceae (Lichenes), Lophocoleaceae (Marchantiophyta), and Apocynaceae, Arecaceae, Asteraceae, Bromeliaceae, Brunelliaceae, Clusiaceae, Ericaceae, Fabaceae, Hypericaceae, Lamiaceae, Melastomataceae, Orchidaceae, O...

Evolución de plantas Neotropicales: la perspectiva filogenética VI El Simposio está dedicado a mostrar los últimos avances acerca de las relaciones filogenéticas de grupos de plantas neotropicales y los procesos evolutivos involucrados en su diversificación como morfología, biología reproductiva y biogeografía. Organizadores: Santiago Madriñán - La...

Comparison of collections of Libertia colombiana (Foster 1939) from Colombia, Ecuador, and Peru show that the Bolivian L. boliviana (Foster 1946) cannot be upheld as a separate species. We provide an expanded description of L. colombiana and establish its range across the Andean paramo as far south as Bolivia, noting the first collections for Ecuad...

Cipura gigas is a new species of this Neotropical genus of nine species that extend from Paraguay in the south to Cuba and Mexico in the north. Apparently most closely related to the widespread C. paludasa, C. gigas is distinguished by its height (50-100 cm), the large bulb (ca. 3 cm diam.) with resinous tunics, basal leaves that are mostly 8-10 mm...
