Recerca

A study published in the journal Nature,  in which about 130 researchers have worked on, among them Josep Maria Ninot and Alba Anadon, from the Biodiversity Research Institute of University of Barcelona, led by scientists from the Senckenberg Biodiversity and Climate Research Centre (Germany) and the University of Edinburgh, analyzes changes in vegetation structure in the tundra.

The study focuses on the most exhaustive data obtained so far on tundra plants, gathering information from almost 120 places, mostly from the Arctic regions but also from Alpine mountains, such as the Alps and the Pyrenees. The database used in this study, Tundra Trait Team , comes from an open collaboration action. Josep M. Ninot and Alba Anadon Rosell are also members of the Department of Evolutionary Biology, Ecology and Environmental Sciences, of the University of Barcelona.

In the study, the vegetation is analysed based on five plant functional treats, such as the canopy height or the nitrogen concentration in the leaves, of about 450 tundra species, which results in more than 56,000 records. The variation in these traits is observed both in the repetition of their measurement in the same place after 30 years, as well as comparing observations of the same species along a gradient of temperatures in space.
