Cover Story: High alpine meadows harbour rich butterfly diversity, but this diversity is threatened by climate change and changes in agricultural practices. To understand how species can be conserved, in- depth studies of their ecological requirements are necessary. This is why we analysed the ecology of the water ringlet Erebia pronoe in a study area in the eastern central Alps near Großglockner. We analysed the behaviour, resource use and population structure of this species. In general, Erebia pronoe adults use a wide array of resources combined with a slight specialisation to avoid niche overlap with closely related species. The resulting ecological flexibility seems to be an adaptation to unpredictable environmental conditions. The combination of opportunism and modest specialisation is a good basis for coping with future changes. View this paper
