Manipulation experiments for the assessment and monitoring of climate change impacts on vegetation of in alpine and polar ecosystems
This thesis focused on the impacts of climate change on terrestrial ecosystems of alpine (Central Italian Alps) and Polar (Maritime Antarctica) tundra habitats, two of the three areas of the world where had been recorded the greatest air temperature warming since 1950. The alpine site is located at...
