Study on the Phenological Changes of Snow and Lake Ice in Qinghai Lake Basin based on MODIS Data

Gaoyuan qixiang
Phenological changes are of great significance to the study of climate response and ecological environment.Based on the MODIS V6 snow product and reflectivity product in the past 20 years， the snow and lake ice phenology in the Qinghai Lake Basin were ...

Winter climate change in alpine tundra: plant responses to changes in snow depth and snowmelt timing [PDF]

, 2018
Snow is an important environmental factor in alpine ecosystems, which influences plant phenology, growth and species composition in various ways. With current climate warming, the snow-to-rain ratio is decreasing, and the timing of snowmelt advancing. In

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

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

Movement 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 ...

Changes in alpine plant growth under future climate conditions [PDF]

, 2010
Alpine shrub- and grasslands are shaped by extreme climatic conditions such as a long-lasting snow cover and a short vegetation period. Such ecosystems are expected to be highly sensitive to global environmental change.

Variability in snow cover phenology in China from 1952 to 2010

, 2015
. Daily snow observation data from 672 stations in China, particularly the 296 stations with over 10 mean snow cover days (SCDs) in a year during the period of 1952–2010, are used in this study.

Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

Oikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.

A 20-Year MODIS-Based Snow Cover Dataset for Svalbard and Its Link to Phenological Timing and Sea Ice Variability [PDF]

Remote Sensing, 2020
The climate in Svalbard has been warming dramatically compared with the global average for the last few decades. Seasonal snow cover, which is sensitive to temperature and precipitation changes, is therefore expected to undergo both spatial and temporal changes in response to the changing climate in Svalbard.

Addressing biases in sliding window analysis gives new insight into the response of parturition date to weather in a wild mammal

Oikos, EarlyView.
Animal breeding phenology in temperate and high latitude regions is often predicted by weather variables, such as temperature. Much work on this topic has focused on taxonomic groups that employ adaptive plastic responses to annual variation in an environmental cue, with analytical approaches developed to determine when weather has an effect and the ...
