Growth Responses to Climate and Drought in Relict Cork Oak Populations as a Benchmark of the Species Tolerance
We still lack information on the long-term growth responses to climate of relict tree populations, which often persist in topoclimatic refugia. To fill that research gap, we studied three relict cork oak ( Quercus suber ) populations located in northern Spain using dendrochronology. The sites were s...

We still lack information on the long-term growth responses to climate of relict tree populations, which often persist in topoclimatic refugia.
