Researchers Confirm: Biodiversity Experiment Results Are Realistic
New research from the Senckenberg Centre has investigated whether results from biodiversity experiments are valid, even if experimental plots do not fully match natural conditions.
Researchers at the Senckenberg Centre have examined whether widely used biodiversity experiments, designed to mimic natural diversity, provide valid insights into ecosystem functioning. Critics have long argued that these experimental plots do not accurately reflect natural conditions, as they host species assemblages that are rare or even non-existent in nature.
The study analyzed sites such as the "Jena Experiment." Researchers compared vegetation on two large and long-term grassland experimental plots with equivalent natural and agriculturally used areas. The research team identified unrealistic sections within the experimental plots and excluded them from the analysis.
Surprisingly, the results showed little change even after the unrealistic plots were removed. This confirms that the observed relationships between species diversity and ecosystem function are valid in real-world nature as well. The study was published in "Nature Ecology & Evolution."
The research addresses a long-standing scientific debate about the importance of biodiversity. The scientists emphasize that biodiversity is essential for human survival and its conservation is crucial for future well-being. They state that the findings provide evidence that species loss has significant consequences.
