Computational search for UV radiation resistance strategies in Deinococcus swuensis isolated from Paramo ecosystems. [PDF]

open access: yesPLoS ONE, 2019
Ultraviolet radiation (UVR) is widely known as deleterious for many organisms since it can cause damage to biomolecules either directly or indirectly via the formation of reactive oxygen species. The goal of this study was to analyze the capacity of high-

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.

Seasonal ecophysiology of two páramo species: the dominance of light over water limitations [PDF]

open access: yesFrontiers in Plant Science
Dry and rainy seasons in many ecosystems differ significantly in cloudiness, precipitation, and incident sunlight. These seasonal variations can influence photosynthesis by altering light availability and water stress.

Endophytic Microbial Community DNA Extraction from the Plant Phyllosphere [PDF]

open access: yesBio-Protocol, 2017
The plant phyllosphere, which represents all plant parts that are above the ground, is considered one of the most extensive ecosystems to be colonized by microorganisms, both at the surface as epiphytes or as endophytes within the plant.

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

open access: yesMutis, 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 ...
