Do Trees ‘Talk’ Before Solar Eclipses? Scientists Disagree on New Study
The idea that trees communicate and synchronize their behavior ahead of a solar eclipse has recently captured widespread attention. This fascinating notion stems from research detecting bioelectric signals in spruce trees during a partial solar eclipse in Italy's Dolomite mountains. However, a significant number of researchers remain skeptical, citing critical flaws in the study's methodology and raising questions about the validity of its conclusions.
Researchers monitoring spruce trees in the Dolomites during the October 2022 solar eclipse with custom-built CyberTree devices, observed that trees began adjusting their internal electrical activity hours before the celestial event. Gagliano said that the findings about the older trees in particular emphasize the importance of preserving these trees.
According to Monica Gagliano, ecologist at Southern Cross University in Australia, "This study illustrates the anticipatory and synchronized responses we observed are key to understanding how forests communicate and adapt, revealing a new layer of complexity in plant behavior," adding, "Basically, we are watching the famous 'wood wide web' in action!"
Despite these intriguing findings, the research has faced considerable criticism from within the scientific community. James Cahill, a plant ecologist at the University of Alberta in Canada, expressed strong concern, stating, "The paper doesn't meet what I would say are the basic standards needed for science. Its sample size is three, which is very low." He also pointed out the large number of variables being tested, suggesting that finding a pattern under such circumstances is almost inevitable.
Cahill and other researchers who spoke to Live Science highlighted the lack of replicates in the study. Justine Karst, a forest ecologist at the University of Alberta, emphasized that "nothing can be concluded from an experiment that does not include replicates." Furthermore, critics suggest that the observed bioelectrical signal changes could simply be a response to approaching darkness or other environmental factors, rather than a sophisticated form of communication related to the eclipse itself.
Adding to the skepticism, Cahill noted the lack of comparison with normal day-night cycles. "They also didn't compare this to just night and day, which is the obvious thing to do and that's very worrisome to me."
In response to questions about the study's publication, The Royal Society Open Science stated that "All research published by Royal Society Open Science goes through thorough peer review before being accepted." They also emphasized the importance of post-publication discussion in their process, encouraging academic debate and constructive criticism.
The study, published in Royal Society Open Science is already generating further research proposals. Alessandro Chiolerio revealed he is leading a research proposal that will be submitted to the European Innovation Council, calling it "a huge step forward, if funded."
While the concept of trees communicating during solar eclipses is undoubtedly captivating, the current evidence appears far from conclusive. The scientific community remains divided, with many calling for more rigorous research and larger sample sizes to validate these claims. Does the notion of a 'wood-wide web' hold water, or is this simply a case of misinterpreting natural responses to environmental stimuli? What are your thoughts?
