Alpine bogs of southern Spain show human-induced environmental change superimposed on long-term natural variations

Abstract Recent studies have proved that high elevation environments, especially remote wetlands, are exceptional ecological sensors of global change. For example, European glaciers have retreated during the 20th century while the Sierra Nevada National Park in southern Spain witnessed the first com...
