Description:
The Catalan Institute of Ornithology (ICO) - as proposed at the Catalan Strategy for Adapting to Climate Change 2013-2020 (ESCACC) - has developed a Climate Connectivity Indicator in bird populations to evaluate the response of biodiversity to the adaptation measure: "Improvement of ecological connectivity, in order to strengthen the resilience capacity of species against global change".
This indicator has been constructed considering two variables in a total of 88 species: the changes in the predicted climatic distribution, and the changes in the average size of the optimal zones.

NWPOutcome:
Two study hypotheses are presented from the results of the study:
a) The good connectivity in the areas of distribution of birds in Catalonia could offset the effects that climate change causes in populations.
b) The indicator does not reflect temporary changes because they are not giving (at the moment) to be masked by the effect of other factors of global change.
This work opts for the second interpretative hypothesis. Previous studies in Catalonia show that, as a whole, populations of open-source species show a negative global tendency due to the growing rural abandonment, while forest species increase their populations due to the natural growth of vegetation.
Therefore, we must keep an eye on the changes in connectivity as possibly responsible for population changes in the future.
