Photosynthetic Traits of Páramo Plants Subjected to Short-Term Warming in OTC Chambers

open access: yesPlants, 2022
Global warming and changes in land use are some of the main threats to high mountain species. Both can interact in ways not yet assessed. In this study, we evaluated the photosynthetic responses of six common páramo species within a warming experiment ...

Multi-predictor mapping of soil organic carbon in the alpine tundra: a case study for the central Ecuadorian páramo

open access: yesCarbon Balance and Management, 2021
Background Soil organic carbon (SOC) affects essential biological, biochemical, and physical soil functions such as nutrient cycling, water retention, water distribution, and soil structure stability.

Land use change in the Ecuadorian páramo: The impact of expanding agriculture on soil carbon storage

open access: yesArctic, Antarctic, and Alpine Research, 2021
The Andean páramo is notable for high soil carbon storage and its contribution to ecosystem services. However, the páramo’s ability to maintain high soil carbon levels is threatened by land use change from tussock grassland and shrublands to agricultural

Desarrollo sostenible del páramo peruano: estudio de caso de los páramos de Pacaipampa, Frías y Huancabamba, departamento de Piura, Perú

open access: yesRevista Kawsaypacha, 2023
El páramo es un ecosistema cuya importancia radica en la conservación y acumulación de agua y carbono. Su deterioro repercute en el aumento de emisiones y disminuye la recarga de acuíferos.

Land‐Use and Land‐Cover Change in the Páramo of South‐Central Ecuador, 1979–2014

open access: yesLand, 2017
Land use and land cover were mapped between 3500 and 5000 meters above sea level m.a.s.l. in the Río Chambo basin in south-central Ecuador from Landsat MSS, TM, ETM and OLI imagery acquired between 1979 and 2014.

Importance of Fog and Cloud Water Contributions to Soil Moisture in the Andean Páramo

open access: yesHydrology, 2022
Páramos are particular ecosystems of the Tropical Andes, where fog and low-intensity rainfall such as drizzle are commonly frequent—but the contribution of these water sources to soil water replenishment and discharge is not yet clear, mainly because the

Climate Vulnerability Assessment of the Espeletia Complex on Páramo Sky Islands in the Northern Andes

open access: yesFrontiers in Ecology and Evolution, 2020
Some of the largest impacts of climate change are expected in the environmentally heterogeneous and species rich high mountain ecosystems. Among those, the Neotropical alpine grassland above the tree line (c.

Effects of land use on soil CO2 flux in the Paramo de Guerrero, Colombia

open access: yesAgronomía Colombiana, 2016
The Andean paramo is an important global carbon sink and has a fundamental ecological function of capture, regulation and supply of water resources. The soil CO2 efflux is a natural process through which the carbon is released into the atmosphere by ...
