Mountain summits in the Alps becoming increasingly similar
Date:11/30/2007

isappeared since 1907. By contrast, the differences between the summits declined significantly over the same period. Today the summits of the Minor range are not only more similar to each other, they are also more similar to the neighbouring Languard range than before, despite the fact that they are separated from each other within the Bernina Alps by the Val da Fain. "This is a clear sign of the early stages of homogenization," says Gerald Jurasinski, a biogeographer from the University of Bayreuth. "We suspect that the accessibility and popularity of these summits among climbers is playing a role here after all, seeds can also be carried on peoples clothes and shoes. But unfortunately there is not yet any data for this," remarks Jrgen Kreyling of the Helmholtz Centre for Environmental Research - UFZ. The two researchers hope their work will draw attention to the fact that biodiversity means more than species richness. The composition of the species spectrum, beta diversity and functional diversity also play an important role in functioning ecosystems.
