Climate change is altering all of the earth’s ecosystems, practically without exception, but we tend to focus more on those that will suffer extremely high temperatures due to this change than on temperate or cold ecosystems, leaving aside glaciers and poles that warn us a lot as well.
Thus, it is also necessary to study the response of the biodiversity of these cold, but not extreme, environments, and María de Mar Delgado is doing so based on a species of bird, the snow finch, which, due to the fact that inhabiting the high parts of the mountain massifs, the progressive isolation of its habitat due to the increase in global temperatures is very evident.
