Climate change and aquatic macroinvertebrates
Climate change is a process of change at a planetary level linked to human activities, which has as its most significant feature a rise in mean temperatures. To know the effect of this warming on the Sierra de Guadarrama aquatic fauna, in the years 2008-2009 were compared the populations of aquatic macroinvertebrates in relation to the ones from the seventies. These latest data came from a doctoral thesis, which carried out a detailed inventory of aquatic invertebrate species along an altitudinal gradient in the Lozoya River.
The goal of this work was to detect a possible rise of populations as a result of a warming of the water temperature, and their move to the highest altitudinal zones, in order to adapt to the temperature rise.
