Abstract While numerous studies report shifts in vegetation phenology, in this regard eddy covariance (EC) data, despite its continuous high-frequency observations, still requires further exploration. Furthermore, there is no general consensus on opt

Abstract Fire is a crucial factor in terrestrial ecosystems playing a role in disturbance for vegetation dynamics. Process‐based fire models quantify fire disturbance effects in stand‐alone dynamic global vegetation models (DGVMs) and their advan

The terrestrial biosphere absorbs a large fraction of emitted CO2, and thus, plays a critical role in climate change projections. Here, the authors use satellite leaf area and in-situ CO2 measurements to show that most Earth system models largely und

Chitin is the second most abundant biopolymer in nature after cellulose, and it forms an integral part of insect exoskeletons, crustacean shells, krill and the cell walls of fungal spores, where it is present as a high-molecular-weight molecule. In t

Strong spring temperature anomalies can have major impacts on the phenological development of vegetation throughout the season. In particular, an unusually warm spring can lead to premature plant development, while late-spring frost events can damage

Drought detection is crucial for water resources management and global food security. Drought is typically detected using empirical indices, such as the Palmer Drought Severity Index (PDSI). However, those indices lack objectivity and are therefore s

Climate change and extreme weather events have far reaching consequences for terrestrial ecosystems, particularly for vegetation phenology. However, the effects of meteorological variations on phenology are still not well understood, rendering phenol

Satellite data reveal widespread changes in Earth's vegetation cover. Regions intensively attended to by humans are mostly greening due to land management. Natural vegetation, on the other hand, is exhibiting patterns of both greening and browning in
