Land surface phenology in the highland pastures of montane Central Asia: Interactions with snow cover seasonality and terrain characteristics

Remote Sensing of Environment, 2020
Abstract Many studies have shown that high elevation environments are among very sensitive to climatic changes and where impacts are exacerbated. Across Central Asia, which is especially vulnerable to climate change due to aridity, the ability of global climate projections to capture the complex dynamics of mountainous environments is particularly ...

Using by‐catch data from wildlife surveys to quantify climatic parameters and timing of phenology for plants and animals using camera traps

Remote Sensing in Ecology and Conservation, 2020
Gaining a better understanding of global environmental change is an important challenge for conserving biodiversity. Shifts in phenology are an important consequence of environmental change.

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.

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.

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Interplay between snow phenology and vegetation phenology in Alaska under climate change

Advances in Climate Change Research
Snow cover is one of the most important factors controlling Arctic ecosystems' microclimate and plant growth conditions in Arctic ecosystems. Climate change has impacted the timing and spatial variability of both snow cover, and worldwide vegetation ...

Satellite observed changes in the Northern Hemisphere snow cover phenology and the associated radiative forcing and feedback between 1982 and 2013

, 2016
Quantifying continental-scale changes in snow cover phenology (SCP) and evaluating their associated radiative forcing and feedback is essential for meteorological, hydrological, ecological, and societal purposes.

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...
