Determining whether the terrestrial biosphere will be a source or sink of carbon (C) under a future climate of elevated CO2 (eCO2) and warming requires accurate quantification of gross primary production (GPP), the largest flux of C in the global C cycle. We evaluated 6 years (2007–2012) of flux‐derived GPP data from the Prairie Heating and CO2 Enrichment (PHACE) experiment, situated in a grassland in Wyoming, USA. The GPP data were used to calibrate a...

Aim Intraspecific trait variation (ITV) within natural plant communities can be large, influencing local ecological processes and dynamics. Here, we shed light on how ITV in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e. climate and species richness). Specifically, we tested if associations of ITV with temperature, precipitation and species richness were consistent with any of from four hypotheses relating to stress-tolerance and competition. Furthermore, we estimated the degree of correlation...
Data supplement to: Fiehn et al (2020): Estimating CH4, CO2, and CO emissions from coal mining and industrial activities in the Upper Silesian Coal Basin using an aircraft-based mass balance approachAlina Fiehn, Julian Kostinek, Maximillian Ecki, Theresa Klausner, Michał Gałkowski, Jinxuan Chen, Christoph Gerbig, Thomas Röckmann, Hossein Maazallahi, Martina Schmidt, Piotr Korbeń, Jarosław Nȩcki, Paweł Jagoda, Norman Wildmann, Christian Mallaun, Rostyslav Bun, Anna-Leah Nicki, Patrick Jöckel, Andreas Fix & Anke Rolger
Supplementary data with CO2 and CH4 observations from in situ and airplane platforms during a campaign over the Upper Silesian Coal Basin (USCB), Poland, in summer 2018. The campaign is described in the paper: Fiehn, A., Kostinek, J., Eckl, M., Klausner, T., Gałkowski, M., Chen, J., Gerbig, C., Röckmann, T., Maazallahi, H., Schmidt, M., Korbeń, P., Nȩcki, J., Jagoda, P., Wildmann, N., Mallaun, C., Bun, R., Nickl, A.-L., Jöckel, P., Fix, A., and Roiger, A.:...
Nutrition has been hypothesized as an important constraint on brain evolution. However, it is unclear whether the availability of specific nutrients or the difficulty of locating high quality diets limits brain evolution, especially over long periods of time. We show that dietary nutrient content predicted brain size across 42 species of butterflies. Brain size, relative to body size, was associated with the sodium and nitrogen content of a species’ diet. There was no evidence that...
Land ecosystems offer an effective nature-based solution to climate change mitigation by absorbing approximately 30% of anthropically emitted carbon. This absorption is primarily based on constraints from atmospheric and oceanic measurements while quantification from direct studies of the land carbon cycle itself displays great uncertainty. The latter hinders prediction of the future fate of the land carbon sink. Here, we show a unified framework for quantifying land carbon sequestration. The framework unifies all carbon cycle...
