Evolutionary diversification in the hyper-diverse montane forests of the tropical Andes: radiation ofMacrocarpaea(Gentianaceae) and the possible role of range expansion [PDF]
Botanical Journal of the Linnean Society, 2021 AbstractThe humid mid-elevation montane forests (MMF) of the tropical Andes harbour high levels of plant species diversity, contributing to the exceptional overall diversity of the tropical Andean biodiversity hotspot. However, little is known about the diversification dynamics of MMF plant lineages compared to lineages in other Andean biomes. Here, we

TAXON, Volume 71, Issue 5, Page 1013-1024, October 2022., 2022 Abstract Because different tropical forest regions possess their own species diversity and communities, it is crucial to investigate the diversification history of their biota to understand how biodiversity was assembled. However, this requires reliable species concepts and robust, well‐sampled phylogenies.

American Journal of Botany, Volume 108, Issue 7, Page 1143-1165, July 2021., 2021 Premise Comprising five families that vastly differ in species richness—ranging from Gelsemiaceae with 13 species to the Rubiaceae with 13,775 species—members of the Gentianales are often among the most species‐rich and abundant plants in tropical forests. Despite considerable phylogenetic work within particular families and genera, several alternative

Ecology and Evolution, Volume 11, Issue 5, Page 2110-2172, March 2021., 2021 High Andean forests play a key role in providing ecosystem services for neighboring urban settlements. Here, we aimed to identify and understand the effects of anthropogenic perturbations on diversity, composition, and structure of plant communities, as well as aboveground biomass in high Andean forest remnants in the hinterland of Bogotá.

De Macrocarpaeae Grisebach (ex Gentianaceis) Speciebus novisX: A Synopsis of the Genus in Montane Atlantic Forests of Brazil [PDF]
Harvard Papers in Botany, 2011 Abstract. Outside of the principal distribution and major diversification of Macrocarpaea in the Andes, smaller groups of species are found in the Greater Antilles of the Caribbean, Mesoamerica, the Guayana Highlands, and montane Atlantic forests of Brazil.

Ecology and Evolution, Volume 9, Issue 18, Page 10843-10853, September 2019., 2019 We compared genic and intergenic regions of three Dioscorea chloroplast genomes and seven pairs of primers had 80%–100% PCR success rate. Automatic barcoding gap discovery (ABGD), Poisson tree processes (PTP), and generalized mixed Yule coalescence (GMYC) analysis were applied for species delimitation based on the seven loci and successfully identified

Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis‐scenario
Ecology and Evolution, Volume 8, Issue 16, Page 8030-8042, August 2018., 2018 Andean orogeny explains the structuring of genetic diversity in the palm Oenocarpus bataua into four genetic clusters within northwestern South America. These clusters maintain genetic exchange between them, even across the Andes. A hotspot of genetic diversity was determined in the northern Peruvian Amazonia.

Foliar colleters inMacrocarpaea obtusifolia(Gentianaceae): anatomy, ontogeny, and secretion
Botany, 2014 Colleters are secretory structures located in reproductive and (or) vegetative organs of many eudicots. In Gentianaceae Juss., the presence of foliar colleters has been neglected, and anatomical and histochemical studies are scarce. The objectives of this study were to investigate the anatomy, ontogeny, and chemical nature of the secretion found in ...
