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

PhytoKeys, 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.

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

PeerJ, 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.

Caracterización de los lepidópteros fitófagos asociados a la herbivoría de frailejones en la microcuenca de la quebrada Calostros del Parque Nacional Natural Chingaza [PDF]

Mutis, 2013
The paramo ecosystem is one of the most sensitive to changes in climate and land use. These changes in physical conditions may lead to changes in species composition and their life cycles, increasing susceptibility to attack by pathogens and other ...

Peace in Other Terms: Mutual Care Practices Between Soldiers and Frailejones at the Páramo de Sumapaz

Maguaré, 2020
This article argues that the definition of peace from the international agendas on transitional justice and peacebuilding falls short because it ignores non-humans.

Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems. [PDF]

Ecol Evol
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Ensamblajes de anuros y heterogeneidad espacial en un ecosistema de páramo de Colombia [PDF]

Caldasia, 2020
El presente estudio buscó determinar el efecto de la heterogeneidad espacial, producto de los mosaicos vegetales y gradientes ambientales y estructurales del páramo, sobre la estructura del ensamblaje de anuros en un sector del Parque

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

Glob Chang Biol
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.

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

Ecol Evol
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 ...

On the Causes of Rapid Diversification in the Páramos: Isolation by Ecology and Genomic Divergence in Espeletia [PDF]

Frontiers in Plant Science, 2018
How diversity arises and what is the relative role of allopatric and ecological divergence are among the most persistent questions in evolution and ecology.
