Snow Height Sensors Reveal Phenological Advance in Alpine Grasslands

Global Change Biology
ABSTRACTLong‐term phenological data in alpine regions are often limited to a few locations and thus, little is known about climate‐change‐induced plant phenological shifts above the treeline. Because plant growth initiation in seasonally snow‐covered regions is largely driven by snowmelt timing and local temperature, it is essential to simultaneously ...

Relationship between Spatiotemporal Variations of Climate, Snow Cover and Plant Phenology over the Alps—An Earth Observation-Based Analysis

Remote Sensing, 2018
Alpine ecosystems are particularly sensitive to climate change, and therefore it is of significant interest to understand the relationships between phenology and its seasonal drivers in mountain areas.

A longer vernal window: The role of winter coldness and snowpack in driving spring thresholds and lags [PDF]

, 2017
Climate change is altering the timing and duration of the vernal window, a period that marks the end of winter and the start of the growing season when rapid transitions in ecosystem energy, water, nutrient, and carbon dynamics take place.

Mapping forests in monsoon Asia with ALOS PALSAR 50-m mosaic images and MODIS imagery in 2010. [PDF]

, 2016
Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and quantify these effects. In this study, an algorithm

Digging deep to open the white black box of snow root phenology [PDF]

Ecological Research, 2013
Abstract Snow roots are specialized structures recently discovered in the Caucasian alpine snow‐bed plant Corydalis conorhiza . They form extensive networks that grow into snow packs against gravity, most probably to gather nitrogen from snow.

Effect of Snow Cover on Detecting Spring Phenology from Satellite-Derived Vegetation Indices in Alpine Grasslands

Remote Sensing, 2022
The accurate estimation of phenological metrics from satellite data, especially the start of season (SOS), is of great significance to enhance our understanding of trends in vegetation phenology under climate change at regional or global scales. However,

Best environmental predictors of breeding phenology differ with elevation in a common woodland bird species

Ecology and Evolution, 2020
Temperatures in mountain areas are increasing at a higher rate than the Northern Hemisphere land average, but how fauna may respond, in particular in terms of phenology, remains poorly understood.

Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]

, 2017
Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.
