Heraclitus said that one cannot step into the same river twice – a phrase that sums up just how dynamic nature is. Although we often regard the landscape as an unchanging snapshot, the truth is that in ecology, change is the norm. This natural dynamic is intensifying on the world’s mountain peaks as a result of anthropogenic changes. More specifically, the study quantifies how our mountain peaks are home to an ever-increasing number of species. This is because, following rising temperatures, some species are migrating upwards in altitude, joining those that already inhabited the peaks. Whilst this may seem like good news, as it increases biodiversity in some areas, the effect will be temporary. In other words, the plants that previously occupied the mountain peaks are being displaced by the new arrivals, and extinction rates have accelerated over the course of this century. In a climate change scenario, species must migrate, adapt or go extinct. For now, it seems that the third option is the one prevailing.
