Effect of the Andean Geography and Climate on the Specialized Metabolism of Its Vegetation: The Subtribe Espeletiinae (Asteraceae) as a Case Example [PDF]

open access: yesMetabolites, 2021
The Andean mountains are ‘center stage’ to some of the most spectacular examples of plant diversifications, where geographic isolation and past climatic fluctuations have played a major role.

Geography shapes the phylogeny of frailejones (Espeletiinae Cuatrec., Asteraceae): a remarkable example of recent rapid radiation in sky islands [PDF]

open access: yesPeerJ, 2017
Background The páramo ecosystem, located above the timberline in the tropical Andes, has been the setting for some of the most dramatic plant radiations, and it is one of the world’s fastest evolving and most diverse high-altitude ecosystems.

Espeletia praesidentis, a new species of Espeletiinae (Millerieae, Asteraceae) from northeastern Colombia [PDF]

open access: yesPhytoKeys, 2017
A new species of Espeletia from the Páramo de Presidente in northeastern Colombia is described. The species is named Espeletia praesidentis after the name of the páramo, and it is dedicated to the President Juan Manuel Santos, for his persistent efforts ...

A nomenclator for the frailejones (Espeletiinae Cuatrec., Asteraceae) [PDF]

open access: yesPhytoKeys, 2012
The páramos and high Andean forests of the tropical Andes are largely dominated by frailejones (Espeletiinae Cuatrec., Asteraceae). These plants are ecologically and culturally essential for both ecosystems and local inhabitants.

Intraspecific variation in pollination ecology due to altitudinal environmental heterogeneity [PDF]

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
Plant populations in different eco‐regions differed in pollination ecology strategies. These population differences are not explained by differences in pollinator assembly, but by environmental heterogeneity. Abstract Plant‐pollinator interactions are constrained by floral traits and available pollinators, both of which can vary across environmental ...

Genetic markers in Andean Puya species (Bromeliaceae) with implications on plastome evolution and phylogeny [PDF]

open access: yesEcology and Evolution, Volume 12, Issue 8, August 2022., 2022
Comparative analyses revealed plastome features, genomic evolution, divergence time, and phylogenetic relationships of the genus Puya. Plastomes have great potential for phylogenetic recontraction and species discrimination of Puya. Abstract The Andean plant endemic Puya is a striking example of recent and rapid diversification from central Chile to ...

Tropical Land‐Use Change Disrupts Zeta‐Diversity Across Taxa [PDF]

open access: yesGlobal Change Biology, Volume 31, Issue 5, May 2025.
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae) [PDF]

open access: yesNew Phytologist, Volume 210, Issue 4, Page 1430-1442, June 2016., 2016
Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explain such radiations, their relative contributions are seldom examined within a single clade.
