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

St Moritz/Leipzig. Alpine summit vegetation will become increasingly homogenized as a result of climate change, say researchers from the University of Bayreuth and the Helmholtz Centre for Environmental Research writing in the international Journal of Vegetation Science. The biologists assessed data on the composition and species numbers of plants on the summits of seven mountains measuring over 3000 metres in the Bernina range in Switzerland over a period of almost one hundred years. They noticed that as a result of climate change, an upward shift of flora is taking place. This is increasing the number of species on the mountain summits studied, but also leading to an increasing homogenization of the species composition of Alpine summit vegetation. This means that species diversity within individual areas (alpha diversity) is increasing, but that species diversity across ecosystems (beta diversity) is declining.

Seen generally, biodiversity can decline for two main reasons: through the disappearance of species, or when specialised species are replaced by generalists. The resulting homogenization can lead to a reduction in regional biodiversity. Until now, the question of homogenization has, however, primarily been discussed in connection with the impacts of invasive species, and less in the context of climate change. The evaluation of the data from the Bernina range now puts this debate in a new light. For their study, the two researchers analysed data from their colleague Gian-Reto Walther, who investigated the top ten metres of these summits in detail in 2003 and made notes of all the plants. They compared these records with surveys from the years 1907 and 1985. On average, the number of plant species rose from 10 to 28 species per summit. The increasing temperatures has evidently brought about a proper summit meeting. More and more species are now forced to share the summits. At the last count in 2003, however, no species were found to have d
