6/6
Our approach shows the importance of physiological limits in understanding the limits of species distributions, particularly for frost and drought constraints in Europe.

5/6
Finally, we demonstrated that our model was more transferable for predicting the distribution of a species without any distribution data than a model based solely on climate.

4/6
When species experienced negative frost safety margins, the probability of presence fell drastically, whereas this phenomenon was less sensitive to drought safety margins.

3/6
We built a distribution model based on the safety margins for frost and drought, which tests whether the probability of presence of species decreases when they cross their resistance threshold.

2/6
We have collected frost (LT50) and drought (P50) resistance traits for 35 species in Europe and quantified the maximum physiological stress experienced by the species on a European scale. The distance between stress resistance and maximum stress defines a safety margin.

1/6
Better linking distribution models with physiological mechanisms requires a balance between correlative and purely mechanistic approaches. The recent development of trait databases that quantify species' resistance to frost and drought opens a new avenue in this direction.

Great! can i be added?

If it's still possible, I'd like to be added!
