Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone
Ecography, EarlyView.This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Speed of radio wave propagation in dry and wet snow
Лëд и снег, 2017 In recent years, ground-penetrating radars are widely used for measuring thickness and liquid water content in snow cover on land and glaciers. The measurement accuracy depends on radio wave velocity (RWV) adopted for calculations. The RWV depends mainly

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps
Ecography, EarlyView.Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs
Ecography, EarlyView.Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.
