Gross primary productivity (GPP) is a key component of ecosystem carbon fluxes and the carbon balance between the biosphere and the atmosphere. Accurate estimation of GPP is essential for quantifying plant production and carbon balance for grasslands. Satellite-derived vegetation indices (VIs) are often used to approximate GPP. The widely used VIs include atmospherically resistant vegetation in...

In populations that are distributed across steep environmental gradients, the potential for local adaptation is largely determined by the spatial scale of fitness variation relative to dispersal distance. Since altitudinal gradients are generally characterized by dramatic ecological transitions over relatively short linear distances, adaptive divergence across such gradients will typically requ...

Understanding the importance of temperature and precipitation on plant productivity is beneficial, to reveal potential impact climate change vegetation growth. Although some studies have quantified response at local, regional, global scales, changes in climatic constraints over time are not well understood. This study combines normalized difference index (NDVI) net primary production (NPP) mode...

Accurate modelling and mapping of alpine grassland aboveground biomass (AGB) are crucial for pastoral agriculture planning management on the Qinghai Tibet Plateau (QTP). This study assessed effectiveness four popular models (traditional multiple linear regression (MLR), support vector machine (SVM), artificial neural network (ANN), deep (DNN)) with various input combinations (geospatial variabl...

Abstract Earlier snowmelt and more frequent summer drought due to climate warming are considered particularly influential for extratropical alpine plants, which adapted a short growing season high water availability. Here, we explored the combined effects of two drivers with field experiment in late‐successional grassland Swiss Alps (2500 m a.s.l.) over 6–7 years. We advanced delayed by removin...

As a sensitive indicator for climate change, the spring phenology of alpine grassland on Qinghai–Tibet Plateau (QTP) has received extensive concern over past decade. It been demonstrated that temperature and precipitation/snowfall play an important role in driving green-up grassland. However, spatial differences snowfall driven mechanism onset are still not clear. This manuscript establishes se...
