Assessing Mountain Soil Water Storage and Release in a Colombian Páramo With APSIS‐InSAR Data

open access: yesHydrological Processes, Volume 39, Issue 7, July 2025.
InSAR detects seasonal soil swelling across a páramo ridge. Ridges swell during the wet season and lower valleys swell in the dry season. Findings indicate flow in the wet season is rapid from ridges through steep slopes and out of the catchment, whereas in the dry season lower valley sediments swell from a cumulative slower flow.

Marcescence and prostrate growth in tree ferns are adaptations to cold tolerance

open access: yesEcography, Volume 2025, Issue 6, June 2025.
Cold tolerance strategies in plants vary from structural to biochemical permitting many plants to survive and grow on sites that experience freezing conditions intermittently. Although tree ferns occur predominantly across the tropics, they also occur in temperate zones and occasionally in areas that experience sub‐zero temperatures, and how these ...
