130 researchers - among them Stefan Dullinger and Karl Hülbl from the Department of Botany and Biodiversity Research - pulled together data measured during thousands of hours of field work at Alpine and Arctic sites to investigate vascular plant changes across the tundra biome. At almost all sites, plant height increased over the past 30 years, mainly by the immigration of taller species. However, changes toward more competitive, acquisitive plant traits were only pronounced in wet tundra sites. At warming, but dry sites, plant traits indicated more conservative strategies with moisture limiting plant growth. (source: UZH)
