On the adaptation of Tunisian olive groves to bioclimatic conditions: The olive tree has been cultivated in Tunisia since Roman times under different bioclimatic conditions in exclusively rainfed groves: in the south with less than 250 mm of rainfall and in the north with more than 600 mm [1]. Apart from the different olive tree species in each of the regions, it is clear that the density of olive trees is strictly correlated with rainfall, ranging from 16 olive trees per hectare in the South to nearly a hundred olive trees per hectare in the North; so that it is possible to faithfully superimpose the density map of olive trees on the map of isohyets. Empirically, over millennia and outside of any protocol or procedure, the peasants have naturally adapted to the natural conditions of the environment and it is difficult to imagine that things can be otherwise.

Thank you for your kind invitation. The topic of Physiological and Ecological Adaptations of Plants to Climate Change is highly relevant and timely. I will review the special issue details and consider potential submissions from my current and upcoming work. I will also share this call with colleagues who may be interested in contributing.

I appreciate the opportunity and look forward to staying engaged with this initiative.

Best regards,
