An international team of researchers from the Max Planck Institute for Developmental Biology, University of Tübingen, Technical University of Madrid, and UC Berkeley studied populations of the thale cress plant, Arabidopsis thaliana, collected from over 500 geographic locations in Europe, commonly used for biological research. Growing these plants in Spain and Germany under dry conditions revealed how individual plants responded to heat and drought.

The investigators were particularly interested in how the unique blend of genetic mutations enables the different individuals of the same species to resist experimentally simulated climates. As some of these mutations may confer physiological advantages, the main goal of this study was to rank their fitness for the future survival of the species.

Data - Models - Temperatures - Precipitation - Decades

This data was then combined with models predicting how temperatures and precipitation are expected to shift geographically in the next few decades in order to understand how plant biodiversity will be affected by climate change caused by human activity.

"On the basis of our calculations up to the year 2050, we...
