Global Apparent Temperature Sensitivity of Terrestrial Carbon Turnover Modulated by Hydrometeorological Factors

The ecosystem carbon turnover time— an emergent ecosystem property that partly determines the feedback between the terrestrial carbon cycle and climate— is strongly controlled by temperature. However, it remains uncertain to what extent …

Estimating Causal Networks in Biosphere-Atmosphere Interaction with the PCMCI Approach

The dynamics of biochemical processes in terrestrial ecosystems are tightly coupled to local meteorological conditions. Understanding these interactions is an essential prerequisite for predicting, e.g. the response of the terrestrial carbon cycle to …

Drought, Heat, and the Carbon Cycle: A Review

Purpose of the ReviewWeather and climate extremes substantially affect global- and regional-scale carbon (C) cycling, and thus spatially or temporally extended climatic extreme events jeopardize terrestrial ecosystem carbon sequestration. We …

Contrasting and Interacting Changes in Simulated Spring and Summer Carbon Cycle Extremes in European Ecosystems

Climate extremes have the potential to cause extreme responses of terrestrial ecosystem functioning. However, it is neither straightforward to quantify and predict extreme ecosystem responses, nor to attribute these responses to specific climate …

Ecosystem Functioning Is Enveloped by Hydrometeorological Variability

Terrestrial ecosystem processes, and the associated vegetation carbon dynamics, respond differently to hydrometeorological variability across timescales, and so does our scientific understanding of the underlying mechanisms. Long-term variability of …

Reverse Engineering Model Structures for Soil and Ecosystem Respiration: The Potential of Gene Expression Programming

Accurate model representation of land- atmosphere carbon fluxes is essential for climate projections. However, the exact responses of carbon cycle processes to climatic drivers often remain uncertain. Presently, knowledge derived from experiments, …

Ecology: Ecosystem Responses to Climate Extremes

Extreme drought or wet conditions have now been found to strongly influence the vegetative development of ecosystems. Semi-arid regions are most affected - raising concerns about their vulnerability to long-term drought in the future. © 2015 …

Effects of Climate Extremes on the Terrestrial Carbon Cycle: Concepts, Processes and Potential Future Impacts

Extreme droughts, heat waves, frosts, precipitation, wind storms and other climate extremes may impact the structure, composition and functioning of terrestrial ecosystems, and thus carbon cycling and its feedbacks to the climate system. Yet, the …

Comparing Observations and Process-Based Simulations of Biosphere-Atmosphere Exchanges on Multiple Timescales

Terrestrial biosphere models are indispensable tools for analyzing the biosphere-atmosphere exchange of carbon and water. Evaluation of these models using site level observations scrutinizes our current understanding of biospheric responses to …

Deciphering the Components of Regional Net Ecosystem Fluxes Following a Bottom-up Approach for the Iberian Peninsula

Quantification of ecosystem carbon pools is a fundamental requirement for estimating carbon fluxes and for addressing the dynamics and responses of the terrestrial carbon cycle to environmental drivers. The initial estimates of carbon pools in …
