Findings From Experimental Biodiversity Sites Are Reliable

These sites contain combinations of species that are not found in the real world, which has led some ecologists to question the findings from biodiversity experiments. But the positive effects of biodiversity for the functioning of ecosystems are more than an artefact of experimental design. This is the result of a new study led by an international team of researchers from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), the University of Bern and the Senckenberg Biodiversity and Climate Research Centre. For their study, they removed 'unrealistic' communities from the analysis of data from two large-scale experiments. The results that have now been published in "Nature Ecology & Evolution" show that previous findings are, indeed, reliable.
