Progress in understanding the hydrology of high-elevation Andean grasslands under changing land use

Giovanny M. Mosquera et al.

Summary: High-elevation grasslands play a crucial role in providing hydrological services, but research on the hydrological function of grasslands in montane regions is still limited. Most hydrological studies have focused on paramos in the Andean region, especially in Ecuador, while research on punas and jalcas is scarce.

Hydrometeorological Factors Controlling the Stable Isotopic Composition of Precipitation in the Highlands of South Ecuador

Dario X. Zhina et al.

Summary: Knowledge about precipitation generation in the tropical Andes is limited due to the lack of water stable isotope data. This study investigated the isotopic composition of precipitation in the Paramo highlands of southern Ecuador using event-based data and identified key factors controlling the isotopic composition.

Vegetation effects on soil pore structure and hydraulic properties in volcanic ash soils of the high Andes

Sebastian Paez-Bimos et al.

Summary: Soil hydraulic properties and pore structure are significantly influenced by vegetation types, with cushion-forming plants promoting higher water retention and saturated hydraulic conductivity. The topography has a minor effect on soil hydraulic properties. The findings highlight the importance of vegetation types for soil hydrology, as cushion-forming plants can enhance soil water storage and regulate water flows.

The effect of natural infrastructure on water erosion mitigation in the Andes

Veerle Vanacker et al.

Summary: Comprehensive assessments are necessary to expand the knowledge on natural infrastructure for erosion mitigation in the Andes, moving beyond individual case studies. The protection and conservation of natural vegetation have the strongest impact on soil quality, while reforestation and soil and water conservation measures also contribute significantly, though to a lesser extent.

A field, laboratory, and literature review evaluation of the water retention curve of volcanic ash soils: How well do standard laboratory methods reflect field conditions?

Giovanny M. Mosquera et al.

Summary: The study reveals that standard laboratory methods using small sample volumes only partially mimic the water retention curve of Andosols, and significantly overestimate the water content at higher matric potentials.

Do mixing models with different input requirement yield similar streamflow source contributions? Case study: A tropical montane catchment

Jorge Ramon et al.

Summary: This study verified the performance of two hydrogeochemical mixing models with different input requirements in a tropical montane headwater catchment in the Ecuadorian Andes. Results showed that a mixing model requiring only a few tracers can provide similar outcomes as models demanding more tracers. This highlights the value of detailed hydrogeochemical characterization for deriving cost-efficient monitoring strategies.
