As significant evidence of ice-rich permafrost degradation due to climate warming, thermokarst lake was developing and undergoing substantial changes. Thermokarst lake was an essential ecosystem component, which significantly impacted the global carbon c
Here we provide the trait dataset that served as basis for the analysis of the global spectrum of plant form and function presented in Díazet al.9–the ‘Global Spectrum of Plant Form and Function Dataset’ (short here ‘Global Spectrum Dataset’). The dataset is predominantly based on trait...

Fundamental axes of variation in plant traits result from trade-offs between costs and benefits of resource-use strategies at the leaf scale. However, it is unclear whether similar trade-offs propagate to the ecosystem level. Here, we test whether trait
Environmental stress is increasing worldwide, yet we lack a clear picture of how stress disrupts the stability of microbial communities and the ecosystem services they provide. Here, we present the first evidence that naturally-occurring microbiomes display network properties characteristic of unstable co...
