Snow and vegetation seasonality influence seasonal trends of leaf nitrogen and biomass in Arctic tundra

open access: yesEcosphere, 2023
Climate change, including both increasing temperatures and changing snow regimes, is progressing rapidly in the Arctic, leading to changes in plant phenology and in the seasonal patterns of plant properties, such as tissue nitrogen (N) content and ...

Evaluation of E3SM land model snow simulations over the western United States [PDF]

open access: yesThe Cryosphere, 2023
Seasonal snow has crucial impacts on climate, ecosystems, and humans, but it is vulnerable to global warming. The land component (ELM) of the Energy Exascale Earth System Model (E3SM) mechanistically simulates snow processes from accumulation, canopy ...

Facilitative Effects of <i>Alnus viridis</i> ssp. <i>fruticosa</i> on <i>Betula nana</i> ssp. <i>exilis</i> Growth in Arctic Alaska. [PDF]

open access: yesEcol Evol
We investigated how Siberian alder influences the growth of dwarf birch in the low Alaskan Arctic. Using growth rings, we found that Siberian alder promotes dwarf birch growth overall despite delaying and shortening the growing season through enhancing snow depths.

Relative Influence of Timing and Accumulation of Snow on Alpine Land Surface Phenology [PDF]

open access: yesJournal of Geophysical Research: Biogeosciences, 2018
AbstractTiming and accumulation of snow are among the most important phenomena influencing land surface phenology in mountainous ecosystems. However, our knowledge on their influence on alpine land surface phenology is still limited, and much remains unclear as to which snow metrics are most relevant for studying this interaction.

Characteristics of Snow Depth and Snow Phenology in the High Latitudes and High Altitudes of the Northern Hemisphere from 1988 to 2018

open access: yesSSRN Electronic Journal, 2022
Snow cover is an important part of the Earth’s surface and its changes affect local and even global climates due to the high albedo and heat insulation. However, it is difficult to directly compare the results of previous studies on changes in snow cover in the Northern Hemisphere mainland (NH) due to the use of different datasets, research methods, or

Impact of Snowpack on the Land Surface Phenology in the Tianshan Mountains, Central Asia

open access: yesRemote Sensing, 2022
The accumulation and ablation processes of seasonal snow significantly affect the land surface phenology in a mountainous ecosystem. However, the ability of snow to regulate the alpine land surface phenology in the arid regions is not well described in ...

Snow Cover Phenology Change and Response to Climate in China during 2000–2020

open access: yesRemote Sensing, 2022
Snow cover phenology (SCP) is critical to the climate system. China has the most comprehensive snow cover distribution in the middle and low latitudes and has shown dramatic changes over the past few decades. However, the spatiotemporal characteristics of SCP parameters and their sensitivity to meteorological factors (temperature and precipitation ...

Observed earlier start of the growing season from middle to high latitudes across the Northern Hemisphere snow-covered landmass for the period 2001–2014

open access: yesEnvironmental Research Letters, 2020
Vegetation phenology in spring has received much attention for its importance to terrestrial ecosystem carbon exchange and climate–biosphere interactions studies.

Sea ice and snow phenology in the Canadian Arctic Archipelago from 1997 to 2018

open access: yesArctic Science, 2021
The multiple islands and narrow channels that form the Canadian Arctic Archipelago (CAA) complicate snow/ice monitoring, as coarse resolution satellite observations are unable to resolve smaller-scale changes in snow/ice cover. We present the first study

Phenological drivers of ungulate migration in South America: characterizing the movement and seasonal habitat use of guanacos

open access: yesMovement Ecology, 2022
Background Migration is a widespread strategy among ungulates to cope with seasonality. Phenology, especially in seasonally snow-covered landscapes featuring “white waves” of snow accumulation and “green waves” of plant green-up, is a phenomenon that ...
